POWER ADAPTOR WITH INTEGRATED SERVER ANTENNA
BACKGROUND
[0001] Repeaters can be used to increase the quality of wireless communication
between a wireless device and a wireless communication access point, such as a
cell tower. Repeaters can improve the quality of the wireless communication by
amplifying, filtering, and/or applying other processing techniques to uplink
and
downlink signals communicated between the wireless device and the wireless
communication access point.
.. [0002] As an example, the repeater can receive, via an antenna, downlink
signals
from the wireless communication access point. The repeater can amplify the
downlink signal and then provide an amplified downlink signal to the wireless
device.
In other words, the repeater can act as a relay between the wireless device
and the
wireless communication access point. As a result, the wireless device can
receive a
stronger signal from the wireless communication access point. Similarly,
uplink
signals from the wireless device (e.g., telephone calls and other data) can be
received at the repeater. The repeater can amplify the uplink signals before
communicating, via an antenna, the uplink signals to the wireless
communication
access point.

EXAMPLE EMBODIMENTS
[0018] An initial overview of technology embodiments is provided below and
then
specific technology embodiments are described in further detail later. This
initial
summary is intended to aid readers in understanding the technology more
quickly
but is not intended to identify key features or essential features of the
technology nor
is it intended to limit the scope of the claimed subject matter.
[0019] In an example, as illustrated in FIG. 1, a bi-directional repeater
system can
comprise a repeater 100 connected to an outside antenna 104 or donor antenna
104
and an inside antenna 102 or server antenna 102. The repeater 100 can include
a
donor antenna port that can be internally coupled to a second duplexer (or
diplexer
or multiplexer or circulator or splitter) 114. The repeater 100 can include a
server
antenna port that can also be coupled to a first duplexer (or diplexer or
multiplexer or
circulator or splitter) 112. Between the two duplexers, 114 and 112, can be
two
paths: a first path and a second path. The first path can comprise a low noise
amplifier (LNA) with an input coupled to the first duplexer 112, a variable
attenuator
coupled to an output of the LNA, a filter coupled to the variable attenuator,
and a
power amplifier (PA) coupled between the filter and the second duplexer 114.
The
LNA can amplify a lower power signal with minimal degradation of the signal to
noise
ratio of the lower power signal. The PA can adjust and amplify the power level
of the
lower power signal by a desired amount. A second path can comprise an LNA with
an input coupled to the second duplexer 114, a variable attenuator coupled to
an
output of the LNA, a filter coupled to the variable attenuator, and a PA
coupled
between the filter and the first duplexer 112. The first path can be a
downlink
amplification path or an uplink amplification path. The second path can be a
downlink amplification path or an uplink amplification path. The repeater 100
can
also comprise a controller 106. In one example, the controller 106 can include
one
or more processors and memory. The controller can be communicatively coupled
to
the amplifiers, variable attenuators, LNA, PA, and other desired active
components.
The controller can be used to turn components on, off, control signal levels,
receive
3
CA 3074191 2020-02-28
data from the signal, input data to the signal, and apply other desired signal
processing.
[0020] FIG. 2 illustrates an exemplary repeater 220 in communication with a
wireless
device 210 and a base station 230. The repeater 220 (also referred to as a
cellular
signal amplifier) can improve the quality of wireless communication by
amplifying,
filtering, and/or applying other processing techniques via a signal amplifier
222 to
uplink signals communicated from the wireless device 210 to the base station
230
and/or downlink signals communicated from the base station 230 to the wireless
device 210. In other words, the repeater 220 can amplify or boost uplink
signals
and/or downlink signals bi-directionally. In one example, the repeater 220 can
be at
a fixed location, such as in a home or office. Alternatively, the repeater 220
can be
attached to a mobile object, such as a vehicle or a wireless device 210. The
repeater can be a signal booster, such as a cellular signal booster.
[0021] In one configuration, the repeater 220 can be configured to be
connected to a
device antenna 224 (e.g., an inside antenna, server antenna, or a coupling
antenna)
and a node antenna 226 (e.g., an outside antenna or donor antenna). The node
antenna 226 can receive the downlink signal from the base station 230. The
downlink signal can be provided to the signal amplifier 222 via a second
coaxial
cable 227 or other type of wired, wireless, optical, or radio frequency
connection
operable to communicate radio frequency signals. The signal amplifier 222 can
include one or more radio signal amplifiers for amplification and filtering of
cellular
signals. The downlink signal that has been amplified and filtered can be
provided to
the device antenna 224 via a first coaxial cable 225 or other type of radio
frequency
connection operable to communicate radio frequency signals. The device antenna
224 can communicate the downlink signal that has been amplified and filtered
to the
wireless device 210.
[0022] Similarly, the device antenna 224 can receive an uplink signal from the
wireless device 210. The uplink signal can be provided to the signal amplifier
222
via the first coaxial cable 225 or other type of wired, wireless, optical, or
radio
.. frequency connection operable to communicate radio frequency signals. The
signal
4
CA 3074191 2020-02-28
amplifier 222 can include one or more radio signal amplifiers for
amplification and
filtering of cellular signals. The uplink signal that has been amplified and
filtered can
be provided to the node antenna 226 via the second coaxial cable 227 or other
type
of wired, wireless, optical, or radio frequency connection operable to
communicate
radio frequency signals. The node antenna 226 can communicate the uplink
signal
that has been amplified and filtered to a node, such as base station 230.
[0023] In one embodiment, the device antenna 224 and the node antenna 226 can
be integrated as part of the repeater 220. Alternatively, the repeater 220 can
be
configured to be connected to a separate device antenna 224 or node antenna
226.
The device antenna and the node antenna may be provided by a different
provider
than the repeater 220.
[0024] In one example, the repeater 220 can send uplink signals to a node
and/or
receive downlink signals from the node. While FIG. 2 shows the node as a base
station 230, this is not intended to be limiting. The node can comprise a
wireless
wide area network (VVVVAN) access point (AP), a base station (BS), an evolved
Node B (eNB), a next generation Node B (gNB), a baseband unit (BBU), a remote
radio head (RRH), a remote radio equipment (RRE), a relay station (RS), a
radio
equipment (RE), a remote radio unit (RRU), a central processing module (CPM),
or
another type of WWAN access point.
[0025] In one configuration, the repeater 220 used to amplify the uplink
and/or a
downlink signal can be a handheld booster. The handheld booster can be
implemented in a sleeve of the wireless device 210. The wireless device sleeve
may
be attached to the wireless device 210, but may be removed as needed. In this
configuration, the repeater 220 can automatically power down or cease
amplification
when the wireless device 210 approaches a particular base station. In other
words,
the repeater 220 may determine to stop performing signal amplification when
the
quality of uplink and/or downlink signals is above a defined threshold based
on a
location of the wireless device 210 in relation to the base station 230.
[0026] In one example, the repeater 220 can include a battery to provide power
to
5
CA 3074191 2020-02-28
various components, such as the signal amplifier 222, the device antenna 224,
and
the node antenna 226. The battery can also power the wireless device 210
(e.g.,
phone or tablet). Alternatively, the repeater 220 can receive power from the
wireless
device 210.
[0027] In one configuration, the repeater 220 can be a Federal Communications
Commission (FCC)-compatible consumer repeater. As a non-limiting example, the
repeater 220 can be compatible with FCC Part 20 or 47 Code of Federal
Regulations (C.F.R.) Part 20.21 (March 21, 2013). In addition, the handheld
booster
can operate on the frequencies used for the provision of subscriber-based
services
under parts 22 (Cellular), 24 (Broadband PCS), 27 (AWS-1, 700 megahertz (MHz)
Lower A-E Blocks, and 700 MHz Upper C Block), and 90 (Specialized Mobile
Radio)
of 47 C.F.R. The repeater 220 can be configured to automatically self-monitor
its
operation to ensure compliance with applicable noise and gain limits. The
repeater
220 can either self-correct or shut down automatically if the repeater's
operations
violate the regulations defined in 47 CFR Part 20.21. While a repeater that is
compatible with FCC regulations is provided as an example, it is not intended
to be
limiting. The repeater can be configured to be compatible with other
governmental
regulations based on the location where the repeater is configured to operate.
[0028] In one configuration, the repeater 220 can enhance the wireless
connection
between the wireless device 210 and the base station 230 (e.g., cell tower) or
another type of wireless wide area network (VVWAN) access point (AP). The
repeater 220 can boost signals for cellular standards, such as the Third
Generation
Partnership Project (3GPP) Long Term Evolution (LIE) Release 8,9, 10, 11, 12,
13,
14, 15 or 16, 3GPP 5G Release 15 or 16, or Institute of Electronics and
Electrical
Engineers (IEEE) 802.16. In one configuration, the repeater 220 can boost
signals
for 3GPP LIE Release 16Ø0 (January 2019) or other desired releases. The
repeater 220 can boost signals from the 3GPP Technical Specification (TS)
36.101
(Release 16 July 2019) bands or LTE frequency bands. For example, the repeater
220 can boost signals from the LIE frequency bands: 2, 4, 5, 12, 13, 17, 25,
and 26.
In addition, the repeater 220 can boost selected frequency bands based on the
6
CA 3074191 2020-02-28
country or region in which the signal booster is used, including any of bands
1-85 or
other bands, as disclosed in 3GPP TS 36.104 V16Ø0 (January 2019), and

[0030] The number of LTE or 5G frequency bands and the level of signal
enhancement can vary based on a particular wireless device, cellular node, or
location. Additional domestic and international frequencies can also be
included to
offer increased functionality. Selected models of the repeater 220 can be
configured
to operate with selected frequency bands based on the location of use. In
another
example, the repeater 220 can automatically sense from the wireless device 210
or
base station 230 (or GPS, etc.) which frequencies are used, which can be a
benefit
for international travelers.
[0031] Installation of a repeater inside a vehicle can be difficult because of
the
number of cables used. The number of cables and the length of the cables can
lead
to undesired clutter. In addition, the routing of each cable in an after-
market
installation can require significant efforts. In order to hide the cables in a
vehicle,
various interior vehicle components may need to be removed, including, but not
limited to, the dash board, door panels, seats, carpet, headliner, and other
necessary parts to route a cable from one location to another. In one example,
3
cables are used to install a repeater: a cable between an outside antenna and
the
repeater, a cable between an inside antenna and the repeater, and a cable
between
a power supply and the repeater. Each cable may be routed in a different
direction
based on the location of the repeater, power supply, inside antenna, and
outside
antenna. It can be relatively expensive and time consuming to disassemble the
CA 3074191 2020-02-28
vehicle, route the cables, and reassemble the vehicle. Reducing the routing of
the
cables, or the number of cables needed to install a repeater, such as a
bidirectional
cellular repeater, can enable significant savings in cost and time. It can
also reduce
the number of components in a vehicle that are removed and reinstalled,
thereby
.. reducing the chance of damaging any of the components.
[0032] In one example, a repeater system can comprise a repeater and a power
adaptor integrated with a server antenna. By combining the power adaptor and
server antenna, a single cable can be used to communicate a signal and provide
power to the repeater. This can reduce the number of cables used to install
the
repeater in a vehicle. In this example, the repeater can comprise a donor
port, a
server port, and one or more amplification and filtering paths coupled between
the
donor port and the server port. The power adaptor integrated with the server
antenna can be configured to be coupled to a power source. The power adaptor
integrated with a server antenna can be configured to be coupled to the server
port
to enable the repeater to receive power from the power supply and to
communicate
the signal between the server antenna and the server port. The example
repeater
system will be described more fully below.
[0033] In one example, a repeater system can comprise a repeater and a power
adaptor, and an external server antenna configured to connect to the repeater.
The
external server antenna can be located in an antenna enclosure. The repeater
can
comprise a donor port, a server port, and one or more amplification and
filtering
paths coupled between the donor port and the server port. The donor port can
be
configured to be connected to a donor antenna. The amplification and filtering
paths
can include a first direction amplification and filtering path and a second
direction
amplification and filtering path. The power adaptor can be configured to be
connected to a power source to provide power over coax (POC) to the external
server antenna enclosure. The external server antenna enclosure can be
configured
to provide POC to the server port of the repeater. This example will be
described
more fully in the proceeding paragraphs.
[0034] As illustrated in FIG. 3, a cellular signal booster or repeater 320 can
be
11
CA 3074191 2020-02-28
configured to receive a signal from a user equipment (UE) or wireless device
310 via
a wireless connection of the wireless device 310 with the repeater 320. The
wireless
connection of the wireless device 310 with the repeater 320 can be one or more
of a
wireless personal area network (W-PAN), which can include a Bluetooth v5.1,
Bluetooth v5, Bluetooth v4.0, Bluetooth Low Energy, Bluetooth v4.1, or
Bluetooth
v4.2 configured radio access technology (RAT), or a wireless local area
network (W-
LAN), which can include an Institute of Electronics and Electrical Engineers
(IEEE)
802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.11ac, or IEEE
802.11ad configured RAT. The repeater 320 can be configured to communicate
with
the wireless device 310 through a direct connection, a Near-Field
Communication
(NFC) configured radio access technology (RAT), an Ultra High Frequency (UHF)
configured RAT, a TV White Space Band (TVWS) configured RAT, or any other
industrial, scientific and medical (ISM) radio band configured RAT. Examples
of
such ISM bands include 2.4 gigahertz (GHz), 3.6 GHz, 4.9 GHz, 5 GHz, 5.9 GHz,
or
6.1 GHz.
[0035] As illustrated in FIG. 4, in another example, a repeater can be
configured as a
multiband bi-directional frequency division duplex (FDD) wireless signal
booster 400
configured to amplify an uplink signal and a downlink signal in multiple bands
or
channels using a separate signal path for one or more uplink frequency bands
or
channels and one or more downlink frequency bands or channels. In one
embodiment, adjacent bands can be included on a same signal path. In the
example of FIG. 4, a first band is labeled as Band 1 (B1) and a second band is
labeled as Band 2 (B2). The labeling is intended to be generic, and does not
represent specific bands, such as 3GPP LTE band 1 and band 2.
[0036] A donor antenna 410, or an integrated node antenna, can receive a
downlink
signal. For example, the downlink signal can be received from a base station.
The
downlink signal can be provided to a first B1/B2 diplexer 412, wherein B1
represents
a first frequency band and B2 represents a second frequency band. The first
B1/B2
diplexer 412 can direct selected portions of a received signal to a B1
downlink signal
path and a B2 downlink signal path. A downlink signal that is associated with
B1 can
12
CA 3074191 2020-02-28
travel along the B1 downlink signal path to a first B1 duplexer 414. A portion
of the
received signal that is within the B2 can travel along the B2 downlink signal
path to a
first B2 duplexer 416. After passing the first B1 duplexer 414, the downlink
signal
can travel through a series of amplifiers (e.g. A10, All, and Al2) and
downlink
bandpass filters (e.g. B1 DL BPF) to a second B1 duplexer 418. In addition,
the B2
downlink signal passing through the B2 duplexer 416, can travel through a
series of
amplifiers (e.g. A07, A08, and A09) and downlink band pass filters (e.g. B2 DL
BPF)
to a second B2 duplexer 420. At this point, the downlink signals (B1 or B2)
have
been amplified and filtered in accordance with the type of amplifiers and BPFs
included in the multiband bi-directional wireless signal booster 400. The
downlink
signals from the second B1 duplexer 418 or the second B2 duplexer 420,
respectively, can be provided to a second B1/B2 diplexer 422. The second BI/B2
diplexer 422 can direct the BI/B2 amplified downlink signal to a server
antenna 430,
or an integrated device antenna. The server antenna 430 can communicate the
amplified downlink signal to a wireless device, such as a UE.
[0037] In another example, the server antenna 430 can receive an uplink (UL)
signal
from a wireless device. The uplink signal can include a first frequency range,
such
as a Band 1 signal and a second frequency range, such as a Band 2 signal. The
uplink signal can be provided to the second BI/B2 diplexer 422. The second
BI/B2
diplexer 422 can direct the signals, based on their frequency, to a B1 uplink
signal
path and a B2 uplink signal path. An uplink signal that is associated with B1
can
travel along the B1 uplink signal path to a second B1 duplexer 418, and an
uplink
signal that is associated with B2 can travel along the B2 uplink signal path
to a
second B2 duplexer 420. The second B1 duplexer 418 can direct the B1 uplink
signal to travel through a series of amplifiers (e.g. A01, A02, and A03) and
uplink
bandpass filters (B1 UL BPF) to the first B1 duplexer 414. In addition, the
second
B2 duplexer 420 can direct the B2 uplink signal to travel through a series of
amplifiers (e.g. A04, A05, and A06) and downlink band pass filters (B2 UL BPF)
to
the first B2 duplexer 416. At this point, the uplink signals (B1 and B2) have
been
.. amplified and filtered in accordance with the type of amplifiers and BPFs
included in
13
CA 3074191 2020-02-28
the bi-directional wireless signal booster 400. The uplink signals from the
first B1
duplexer 414 and the first B2 duplexer 416, respectively, can be provided to
the first
B1/B2 diplexer 412. The first B1/B2 diplexer 412 can direct the B1 and B2
amplified
uplink signals to the donor antenna 410, or an integrated device antenna. The
donor
antenna 410, or donor antenna, can communicate the amplified uplink signals to
a
base station.
[0038] In another example, as illustrated in FIG. 5, a repeater 520 can
comprise a
donor port that can be configured to be connected to a donor antenna 524 via a
cable 523. The repeater 520 can further comprise a server port that can be
configured to be connected to a server antenna 522 via a cable 521. The
repeater
can be further configured to be connected to a power supply 526 via a cable
525.
The repeater can be located in a vehicle (e.g., a car, a truck, a recreational
vehicle
(RV), or the like).
[0039] The server port of the repeater 520 can send a filtered, amplified
downlink
signal to the server antenna 522 for transmission of the downlink signal to a
wireless
device, such as a UE. The server antenna 522 can receive an uplink signal from
a
wireless device, such as the UE. The uplink signal can be sent, via the server
port,
to the repeater 520. The donor port can send a filtered, amplified uplink
signal from
the repeater to the donor antenna 524 via cable 523 for transmission of the
uplink
signal to a base station 530. The donor antenna 524 can receive a downlink
signal
from the base station 530. The downlink signal can be sent to the donor port
for
filtering and amplification at the repeater 520. In the example of FIG. 5, a
total of
three cables are used for the power 525, server port connection 521, and donor
port
connection 523. The three cables are typically installed to three separate
locations
in the vehicle.
[0040] FIG. 6a provides another example of a repeater 620 installed in a
vehicle.
The FCC Consumer Booster requirements for a repeater operating in a vehicle
severely limit the amount of power that can be sent from a server port on the
repeater 620 to a server antenna 628. The power limitation ensures that the
amplified cellular signals from the repeater 620 do not interfere with
adjacent
14
CA 3074191 2020-02-28
vehicles or nearby cellular phone users. Accordingly, the server antenna is
typically
located near the user, such as the driver or passenger in a vehicle. Modern
vehicles
typically locate a power source, such as a cigarette lighter adapter (CLA), or
other
direct current (DC) or alternating current (AC) power source near the driver
and/or
passengers. In order to limit the number of cables used for installation of a
repeater
system in a vehicle, while enabling the server antenna to be located near the
user(s), the server antenna can be integrated in a housing with the power
adapter to
form an integrated server antenna 628. In one example, the integrated server
antenna 628 can use a single coaxial cable to deliver both power and uplink
and
.. downlink signals to the repeater 620. This will be described more fully in
the
proceeding paragraphs.
[0041] The repeater 620 can comprise a donor port that can be configured to be
connected to a donor antenna 624 via a cable 623. The donor antenna 624 can be
configured to be coupled to an external location on a vehicle (e.g., a car, a
truck, a
recreational vehicle (RV), or the like). The repeater 620 can further comprise
a
server port that can be configured to be connected, via a cable 625, to a
power
adaptor (e.g., a cigarette lighter adaptor (CLA) or an on-board diagnostics
(OBD) ll
port adaptor) integrated with a server antenna 628.
[0042] The repeater 620 can further comprise one or more amplification and
filtering
paths coupled between the donor port and the server port. The power adaptor
integrated with a server antenna 628 can be configured to be coupled to a
power
source (e.g., a CLA power supply or an OBD ll port power supply). The power
adaptor integrated with a server antenna 628 can be further configured to be
coupled to the server port to enable the repeater 620 to receive power from
the
.. power supply. The cable 625 can also enable the repeater 620 to communicate
uplink and downlink signals between the server antenna integrated with the
power
adaptor 628 and the server port.
[0043] In another example, the repeater can be located in a vehicle. The power
adaptor integrated with a server antenna 628 can transmit a downlink signal,
which
was filtered and amplified by the repeater 620, to a wireless device, such as
a UE
CA 3074191 2020-02-28
(i.e. 310 in FIG. 3). The power adaptor integrated with a server antenna 628
can
receive an uplink signal from the wireless device, such as a UE, at the server
antenna 628 and send the uplink signal to the server port at the repeater 620
for
filtering and amplification at the repeater 620. The donor antenna 624 can
communicate an uplink signal, which was filtered and amplified by the repeater
620,
to a base station 630. The donor port of the repeater 620 can receive a
downlink
signal received at the donor antenna 624 from a base station 630, and filter
and
amplify the downlink signal.
[0044] In another example, the power adaptor integrated with a server antenna
628
.. (i.e. the integrated power adaptor), can be configured to provide power
over coax
(POC) via cable 625 to the repeater 620 via the server port as described in
further
detail with reference to FIG. 6c. The coaxial cable can include an inner
conductor
and an outer conductor. A direct current (DC) bias can be applied to the inner
conductor relative to the outer conductor of the cable. Radio frequency (RF)
signals
(i.e. the UL and DL signals) can travel along the same conductors (e.g. the
inner
conductor and the outer conductor) in the cable 625 (e.g., a coaxial cable) as
the
direct current (DC) bias. For example, the inner conductor of the cable 625
can
carry a positive DC bias and the outer conductor of the cable 625 can be
grounded
or carry a negative DC bias. This example is not intended to be limiting.
Other
types of biasing can be used to provide a desired voltage and current from the
integrated power adaptor 628 and the server port 620.
[0045] In another example, the cable 625 can comprise a leaky coaxial cable or
radiating coaxial cable that can be configured to provide a DL signal from the
repeater 620 to a wireless device.
[0046] In another example, as illustrated in FIG. 6b, the repeater 620 can
comprise
an auxiliary port configured to communicate a DL signal from the auxiliary
port of the
repeater 620 to an auxiliary server antenna 622 via a cable 621. The auxiliary
server antenna 622 can be configured to communicate an UL signal to the
auxiliary
port of the repeater 620. The auxiliary server antenna 622 can provide an
additional
.. coverage area when the coverage area provided by the integrated power
adaptor
16
CA 3074191 2020-02-28
628 is unfavorable.
[0047] In another example, the power adaptor integrated with the server
antenna
628 can comprise the power adaptor with the server antenna integrated with the
power adaptor in a housing. The server antenna can be a cellular antenna
configured to receive UL signals from a UE and transmit DL signals to the UE.
[0048] In another example, the integrated power adaptor 628 can be configured
to
convert 12 volt (V) direct current (DC) power to 5 volt DC power using a step
down
power converter, a step down voltage regulator, or the like. In another
example, the
integrated power adaptor 628 can further comprise one or more charging ports.
A
charging port can be a port with an adapter capable of providing a voltage and
a
current via the integrated power adapter. For example, the charging port can
be a
universal serial bus (USB) port, a lightning port, an Ethernet port, a 120 V
power
adapter, an adapter with a specified voltage and current for a selected
country, and
so forth. In another example, the integrated power adaptor 628 can further
comprise
one or more OBD II ports. In another example, the integrated power adaptor 628
can be configured to be connected to an OBD II port. The OBD ll port can turn
off
when the vehicle turns off.
[0049] In another example, the power adaptor integrated with the server
antenna
628 can be configured to be connected to a plurality of USB adaptors to enable
the
integrated power adaptor 628 to source adequate current to power the repeater
620.
In another example, the power adaptor integrated with the server antenna 628
can
comprise an alternating current (AC) adaptor configured to receive power from
an
AC power source.
[0050] In another example, as illustrated in FIG. 6c, a repeater 650 or signal
booster
650 can comprise a first-direction amplification and filtering path (e.g., an
uplink
amplification and filtering path) and a second-direction amplification and
filtering path
(e.g., a downlink amplification and filtering path). The first-direction
amplification and
filtering path can include a low-noise amplifier 652, a variable attenuator
654, a filter
656 (e.g., a bandpass filter), and a power amplifier 658. The second-direction
17
CA 3074191 2020-02-28
amplification and filtering path can include a low-noise amplifier 651, a
variable
attenuator 653, a filter 655 (e.g., a bandpass filter), and a power amplifier
657. The
first-direction amplification and filtering path can be coupled between a
duplexer 651
and a duplexer 659. The repeater can comprise a microcontroller. The duplexer
659 can be configured to be coupled to a donor antenna 660. The duplexer 651
can
be configured to be coupled to a capacitor (e.g., Cl). This example of a
signal
booster 650 is not intended to be limiting. A repeater configured to be
coupled to a
bias-T DC coupling box 680 can be used in place of the example of the signal
booster 650 provided.
[0051] In one example, the capacitor (e.g., Cl) can be configured to be
coupled via a
coaxial cable 665 to an inductor (e.g., L1) and a bias-T direct current (DC)
coupling
box 680. The inductor (e.g., L1) can be configured to be coupled to a
capacitor
(e.g., C2), which can be configured to be coupled to ground (e.g., GND1). The
inductor (e.g., L1) can be configured to be coupled to a signal booster DC
power
supply 662.
[0052] In one example, the bias-T DC coupling box 680 can comprise an inductor
(e.g., L2), a capacitor (e.g., C4), a capacitor (e.g., C3), and a ground
connection
(e.g., GND2). The bias-T DC coupling box 680 can optionally comprise a server
antenna 670. In an alternative, the bias-T DC coupling box 680 can be
configured to
be coupled to the server antenna 670. In one example, the bias-T DC coupling
box
680 can be configured to comprise both an internal server antenna 670 and an
external server antenna (not shown).
[0053] In one example, the coaxial cable 665 can be configured to be coupled
to an
inductor (e.g., L2) and a capacitor (e.g., C4). The capacitor (e.g., C4) can
be
configured to be coupled to the server antenna 670. The inductor (e.g., L2)
can be
configured to be coupled to a capacitor (e.g., C3) and an external DC power
source
690. The capacitor (e.g., C3) can be coupled to a ground connection (e.g.,
GND2).
[0054] In one example, the bias-T DC coupling box 680 can be configured to
integrated with the server antenna 670 and configured to be coupled to the
external
18
CA 3074191 2020-02-28
DC power source 690 and a server port of the signal booster 650 to enable the
signal booster 650 to receive power from the external DC power source 690 via
the
bias-T DC coupling box 680. In one example, the signal booster 650 can be
configured to communicate a signal between the server antenna 670 and the
server
port of the signal booster 650.
[0055] In one example, the external DC power source 690 can comprise one or
more
of a CLA power supply or an OBD II port power supply. The external DC power
source 690 can be configured to receive power from an AC power source.
[0056] In one example, the bias-T DC coupling box 680 can comprise a CLA or an
OBD II port adaptor. The server antenna 670 can be integrated with the bias-T
DC
coupling box 680 or the server antenna 670 can be separate from the bias-T DC
coupling box 680. In one example, the CLA can be configured to convert 12 volt
DC
power to 5 volt DC power using a step down power converter, a step down
voltage
regulator, or the like. In one example, the CLA can comprise one or more power
adapter ports, such as universal serial bus (USB) ports configured to provide
power
to a user equipment (UE), a wireless device, or any other device configured to
receive power from a power supply.
[0057] In one example, the bias-T DC coupling box 680 can be configured to
provide
power over coax to the signal booster 650 via the coaxial cable 665. The
coaxial
cable 665 can include an inner conductor and an outer conductor. A direct
current
(DC) bias can be applied to the inner conductor relative to the outer
conductor of the
coaxial cable 665. Radio frequency (RF) signals (i.e. the UL and DL signals)
can
travel along the same conductors (e.g. the inner conductor and the outer
conductor)
in the coaxial cable 665 as the direct current (DC) bias. For example, the
inner
conductor of the coaxial cable 665 can carry a positive DC bias and the outer
conductor of the coaxial cable 665 can be grounded or carry a negative DC
bias.
This example is not intended to be limiting. Other types of biasing can be
used to
provide a desired voltage and current from the bias-T DC coupling box 680 to
the
server port of the signal booster 650. The DC bias can be used to power
components of the signal booster 650. The DC bias can be removed prior to the
19
CA 3074191 2020-02-28
duplexer. A signal, such as an uplink signal or downlink signal, can travel
through
the capacitor C1. Accordingly, RF signals can travel between the duplexer and
the
server antenna.
[0058] In one example, the bias-T DC coupling box 680 can comprise an external
server antenna port (not shown), wherein the external server antenna port can
be
configured to be coupled to an external server antenna (not shown). In one
example, the bias-T DC coupling box 680 can include one or more of a splitter,
a
directional coupler, or a tap configured to communicate a signal (i.e. an
uplink signal
or a downlink signal) between: the server antenna 670 and the server port of
the
signal booster 650, and an external server antenna and an external server
antenna
port.
[0059] In one example, the bias-T DC coupling box 680 can be configured to be
coupled to the external DC power source 690 to provide power over coax to an
external server antenna enclosure to be described in further detail in the
proceeding
paragraphs. The external server antenna enclosure can be configured to provide
power over coax to the server port of the signal booster 650.
[0060] In some types of vehicles, a power source is not sufficiently close to
the driver
and/or passenger(s) to enable their UE to communicate with an integrated
server
antenna that includes both the power adapter and server antenna. In one
example,
as illustrated in FIG. 7, an additional server antenna 722 can be added to
allow
additional users to communicate with the repeater 720.
[0061] In the example illustrated in FIG. 7, a repeater 720 can comprise a
donor port
that can be configured to be connected to a donor antenna 724 via a cable 723.
The
donor antenna 724 can be configured to be coupled to an external location on a
vehicle (e.g., a car, a truck, a recreational vehicle (RV), or the like). The
repeater
720 can further comprise a server port that can be configured to be connected,
via a
cable 725, to a power adaptor (e.g., a cigarette lighter adaptor (CLA) or an
on-board
diagnostics (OBD) II port adaptor) integrated with a server antenna 728.
[0062] The repeater 720 can further comprise one or more amplification and
filtering
CA 3074191 2020-02-28
paths coupled between the donor port and the server port. The power adaptor
integrated with a server antenna 728 can be configured to be coupled to a
power
source (e.g., a CLA power supply or an OBD II port power supply). The power
adaptor integrated with a server antenna 728 can be further configured to be
coupled to the server port to enable the repeater 720 to receive power from
the
power supply. The cable 725 can also enable the repeater 720 to communicate
uplink and downlink signals between the server antenna integrated with the
power
adaptor 728 and the server port.
[0063] In another example, the repeater can be located in a vehicle. The power
.. adaptor integrated with a server antenna 728 can transmit a downlink
signal, which
was filtered and amplified by the repeater 720, to a wireless device, such as
a UE.
The power adaptor integrated with a server antenna 728 can receive an uplink
signal
from the wireless device, such as a UE, at the server antenna and send the
uplink
signal to the server port at the repeater 720 for filtering and amplification
at the
repeater 720. The donor antenna 724 can transmit an uplink signal, which was
filtered and amplified at the repeater 720, to a base station 730. The donor
port of
the repeater 720 can receive a downlink signal received at the donor antenna
724
from a base station 730, and filter and amplify downlink signal.
[0064] In another example, the power adaptor integrated with a server antenna
728
(i.e. the integrated power adaptor), can be configured to provide power over
coax
(POC) via cable 725 to the repeater 720 via the server port. The coaxial cable
725
can include an inner conductor and an outer conductor. A direct current (DC)
bias
can be applied to the inner conductor relative to the outer conductor of the
cable
725. Radio frequency (RF) signals (i.e. the UL and DL signals) can travel
along the
same conductors (e.g. the inner conductor and the outer conductor) in the
cable 725
(e.g., a coaxial cable) as the direct current (DC) bias. For example, the
inner
conductor of the cable 725 can carry a positive DC bias and the outer
conductor of
the cable 725 can be grounded or carry a negative DC bias. This example is not
intended to be limiting. Other types of biasing can be used to provide a
desired
voltage and current from the integrated power adaptor 728 and the server port
720.
21
CA 3074191 2020-02-28
[0065] In another example, the cable 725 can comprise a leaky coaxial cable or
radiating coaxial cable that can be configured to provide a DL signal from the
repeater 720 to a wireless device.
[0066] In another example, the integrated power adaptor 728 can comprise an
-- external server antenna port at the integrated power adaptor 728. The
external
server antenna port can be configured to be connected to an external server
antenna 722 via a cable 721. The server antenna of the integrated power
adaptor
can be disconnected from the server port of the repeater when the external
server
antenna 722 is connected to the external server antenna port.
-- [0067] In another example, the integrated power adaptor 728 can comprise a
switch
that directs a DL signal from the repeater 720 to the external server antenna

antenna 822,
comprising a server antenna and a power source, such as a DC power source, can
be configured to be located near a user. Power can be supplied from a power
source 828 to the integrated server antenna 822. The integrated server antenna
can
then be configured to be connected to a server port of the repeater 820 to
provide
POC, allowing both power and the UL and DL signals to be communicated between
the integrated server antenna 822 and the server 820.
[0073] In another example, the repeater 820 can comprise a donor port that can
be
configured to be connected to a donor antenna 824 via a cable 823. The donor
antenna 824 can be configured to be coupled to an external location on a

amplified by the
repeater 820, to a wireless device, such as a UE. The server antenna 822 can
receive an uplink signal from a wireless device, such as a UE, at the server
antenna
822 and send the uplink signal to the server port at the repeater 820 for
filtering and
amplification at the repeater. The donor antenna 824 can communicate an uplink
.. signal, which was filtered and amplified by the repeater 820, to a base
station 830.
The donor port of the repeater 820 can receive a downlink signal received at

signal.
[0076] In another example, the power adaptor 828 can be configured to provide
.. power over coax (POC) via cable 827 to the repeater 820 via the server
antenna
enclosure 822. The coaxial cable 827 can include an inner conductor and an
outer
conductor. A DC bias can be applied to the inner conductor relative to the
outer
conductor of the cable 827. Radio frequency (RF) signals (i.e. the UL and DL
signals) can travel along the same conductors (e.g. the inner conductor and
the
outer conductor) in the cables 827 and 821 (e.g., a coaxial cable) as the
direct
24
CA 3074191 2020-02-28
current (DC) bias. For example, the inner conductor of the cables 827 and 821
can
carry a positive DC bias and the outer conductor of the cables 827 and 821 can
be
grounded or carry a negative DC bias. This example is not intended to be
limiting.
Other types of biasing can be used to provide a desired voltage and current
from the
.. integrated power adaptor 828 and the server port 820.
[0077] In another example, the cable 821 can comprise a leaky coaxial cable or

comprise
an external server antenna configured to be coupled to the server port of the
repeater 820. The external server antenna enclosure 822 can be configured to
be
connected to an external server antenna port of the repeater 820 via a cable
821.
[0079] In another example, the external server antenna enclosure 822 can
comprise
a direct current (DC) power jack integrated with the external server antenna
enclosure 822. The DC power jack can be configured to provide POC to the
server
port of the repeater 820.

more
power adapter ports, such as universal serial bus (USB) ports. In another
example,
the power adaptor 828 can further comprise one or more OBD II ports. In
another
example, the power adaptor 828 can be configured to be connected to an OBD II
port. The OBD II port can turn off when the vehicle turns off.
[0081] In another example, the power adaptor 828 can be configured to be
connected to a plurality of USB adaptors to enable the power adaptor 828 to
source
adequate current to power the repeater 820. In another example, the power
adaptor
828 can comprise an alternating current (AC) adaptor configured to receive
power
from an AC power source. In another example, the power adaptor 828 can be

[00130] Various techniques, or certain aspects or portions thereof, can take
the
form of program code (i.e., instructions) embodied in tangible media, such as
floppy
diskettes, compact disc-read-only memory (CD-ROMs), hard drives, non-
transitory
computer readable storage medium, or any other machine-readable storage medium
wherein, when the program code is loaded into and executed by a machine, such
as
a computer, the machine becomes an apparatus for practicing the various
techniques. Circuitry can include hardware, firmware, program code, executable
code, computer instructions, and/or software. A non-transitory computer
readable
storage medium can be a computer readable storage medium that does not include
signal. In the case of program code execution on programmable computers, the
computing device can include a processor, a storage medium readable by the
processor (including volatile and non-volatile memory and/or storage
elements), at
least one input device, and at least one output device. The volatile and non-
volatile
memory and/or storage elements can be a random-access memory (RAM), erasable
programmable read only memory (EPROM), flash drive, optical drive, magnetic
hard
drive, solid state drive, or other medium for storing electronic data. The low
energy
fixed location node, wireless device, and location server can also include a
transceiver module (i.e., transceiver), a counter module (i.e., counter), a
processing
module (i.e., processor), and/or a clock module (i.e., clock) or timer module
(i.e.,
timer). One or more programs that can implement or utilize the various
techniques
described herein can use an application programming interface (API), reusable
32
CA 3074191 2020-02-28
controls, and the like. Such programs can be implemented in a high level
procedural
or object oriented programming language to communicate with a computer system.
However, the program(s) can be implemented in assembly or machine language, if
desired. In any case, the language can be a compiled or interpreted language,
and
combined with hardware implementations.
[00131] As used herein, the term processor can include general purpose
processors, specialized processors such as VLSI, FPGAs, or other types of
specialized processors, as well as base band processors used in transceivers
to
send, receive, and process wireless communications.
[00132] It should be understood that many of the functional units described in
this
specification have been labeled as modules, in order to more particularly
emphasize
their implementation independence. For example, a module can be implemented as
a hardware circuit comprising custom very-large-scale integration (VLSI)
circuits or
gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or
other
discrete components. A module can also be implemented in programmable
hardware devices such as field programmable gate arrays, programmable array
logic, programmable logic devices or the like.
[00133] In one example, multiple hardware circuits or multiple processors can
be
used to implement the functional units described in this specification. For
example, a
first hardware circuit or a first processor can be used to perform processing
operations and a second hardware circuit or a second processor (e.g., a
transceiver
or a baseband processor) can be used to communicate with other entities. The
first
hardware circuit and the second hardware circuit can be incorporated into a
single
hardware circuit, or alternatively, the first hardware circuit and the second
hardware
circuit can be separate hardware circuits.
[00134] Modules can also be implemented in software for execution by various
types of processors. An identified module of executable code can, for
instance,
comprise one or more physical or logical blocks of computer instructions,
which can,
for instance, be organized as an object, procedure, or function. Nevertheless,
the
33
CA 3074191 2020-02-28
executables of an identified module need not be physically located together,
but can
comprise disparate instructions stored in different locations which, when
joined
logically together, comprise the module and achieve the stated purpose for the
module.
[00135] Indeed, a module of executable code can be a single instruction, or
many
instructions, and can even be distributed over several different code
segments,
among different programs, and across several memory devices. Similarly,
operational data can be identified and illustrated herein within modules, and
can be
embodied in any suitable form and organized within any suitable type of data
structure. The operational data can be collected as a single data set, or can
be
distributed over different locations including over different storage devices,
and can
exist, at least partially, merely as electronic signals on a system or
network. The
modules can be passive or active, including agents operable to perform desired
functions.
[00136] Reference throughout this specification to "an example" or "exemplary"
means that a particular feature, structure, or characteristic described in
connection
with the example is included in at least one embodiment of the present
invention.
Thus, appearances of the phrases "in an example" or the word "exemplary" in
various places throughout this specification are not necessarily all referring
to the
same embodiment.
[00137] As used herein, a plurality of items, structural elements,
compositional
elements, and/or materials can be presented in a common list for convenience.
However, these lists should be construed as though each member of the list is
individually identified as a separate and unique member. Thus, no individual

without indications to the contrary. In addition, various embodiments and
example of
the present invention can be referred to herein along with alternatives for
the various
components thereof. It is understood that such embodiments, examples, and
alternatives are not to be construed as defacto equivalents of one another,
but are to

be considered as separate and autonomous representations of the present
invention.
[00138] Furthermore, the described features, structures, or characteristics
can be
combined in any suitable manner in one or more embodiments. In the following
description, numerous specific details are provided, such as examples of
layouts,
distances, network examples, etc., to provide a thorough understanding of
