1 INTRODUCTION
The FlexWave 2x1 microBTS is an environmentally hardened outdoor base station solution that
supports GSM/AMR voice traffic and GPRS/EDGE data traffic. An Internet Protocol (IP)
backhaul provides the interface between the microBTS and the Base Station Controller (BSC).
All voice and data traffic and all operation and maintenance functions are transported by the IP
backhaul. A complete FlexWave Operations and Maintenance Center - Radio (OMC-R)
management solution is available that provides total control of the microBTS, BSC, and other
FlexWave system elements.
The microBTS, shown in Figure 1, consists of an environmentally-sealed enclosure and various
electronic modules that are housed within the enclosure. Excess heat is dissipated using a
passive cooling system which eliminates the need for external cooling fans. The low profile
design of the enclosure requires minimal real estate for installation. The enclosure may be
mounted from a wall, pole, or overhead cable (strand). A separate base station antenna (not
provided) mounts near the enclosure.

• Provides Power Over Ethernet (POE) to the IP backhaul device
• Provides an RF interface (antenna port) for the base station remote antenna.
• Provides an RF interface (antenna port) for the Network Listen antenna.
• Accepts AC power input.
• Provides a visual indication of unit status
2.1 Primary Components
The microBTS is a fully integrated base station solution that includes the following: radio
transceivers (2), Linear Power Amplifier (LPA), RX Low Noise Amplifier (LNA), duplexer,
power supply, IP switches, Network Listen unit, processor board, carrier board, and enclosure.
The enclosure houses the electronic assemblies, controls RF emissions, seals out dirt and
moisture, and provides passive cooling. The internal components are not user replaceable or
accessible. The base station antenna cable connector, IP backhaul connector, AC power
connector, and the unit status indicator are located on the bottom of the enclosure. The Network
Listen antenna connector is located on the top of the enclosure.
2.2 Mounting
The microBTS may be mounted on a flat vertical surface (such as the side of a building), on a
utility pole, or from a strand. A combination wall/pole mounting bracket is provided with each
unit. Wall or pole-mount installation consists of securing the bracket to the mounting surface
and then hanging the enclosure from the bracket. The bracket may be attached to a variety of
surfaces such as wood, concrete, or masonry. Various fasteners including hex-head capscrews,
tee-nuts, and concrete anchors are provided. A separate strand-mount kit (accessory item) is
available if it is necessary to mount the microBTS from a cable. The mircroBTS should be
mounted in a restricted access location only.
2.3 Fault Detection and Alarm Reporting
The microBTS detects and reports fault and alarm information. A single bottom-mounted Light
Emitting Diode (LED) indicator turns from off to red if a major fault is detected. The status of
the microBTS, the alarm state, and other fault information is summarized and reported over the
IP backhaul. Fault and alarm information may be accessed using the FlexWave OMC-R
management solution.
2.4 IP Backhaul Connection
The IP backhaul cable connection is through an Ethernet port that consists of a single bottommounted hardened RJ-45 female connector. The IP backhaul cable carries the voice and data
traffic plus all OMC-R provisioning, alarm, and performance monitoring communications
between the microBTS and the BSC. The IP backhaul connection also provides DC power
(POE) to the IP backhaul device with a 15 Watt maximum power output at 48 VDC. The
maximum drop cable length is 300 feet (91.4 m).
2.5 Network Listen Antenna Connection
The Network Listen antenna (depending on the option ordered) connection is through a single
top-mounted NMO (female) RF connector. The Network Listen antenna attaches directly to the
NMO connector.
Page 2

2.6 Base Station Antenna Cable Connection
The base station antenna cable connection is through one 50-ohm N-type female connector. The
microBTS includes an internal duplexer which allows a single antenna cable to carry both
forward and reverse path RF signals between the base station antenna and the microBTS.
An externally-mounted lightning protector is available as an accessory. The surge/antenna
connector on the lightning protector is an N-type female connector. The microBTS enclosure
must be properly grounded for the lighting protector to function properly.
2.7 Powering
The microBTS is powered by 90 to 265 VAC (nominal 115 or 230 VAC), 47 to 63 Hz power.
The AC power is supplied through a 15-foot three-wire power cable that is provided with the
enclosure. The power cable connects to a mini 3-pin AC power connector mounted on the
bottom of the microBTS enclosure. The power cable is rated for indoor or outdoor use and must
not be placed within electrical conduit as this will impede the cooling of the cable during usage.
The stub end of the power cable must be routed to an external junction box (not provided) for
connection to the AC power source. A circuit breaker rated at 15 Amps (150 VAC) should be
used to provide overcurrent protection for the microBTS power circuit. It is also recommended
that an external AC outlet (not provided) be installed near the microBTS enclosure to power test
equipment and power tools.
ADCP-75-246 • Issue 1 • 6/2008
2.8 Grounding
A grounding terminal (hex socket capscrew and washer) is provided on the bottom of the
enclosure for connecting a grounding cable to the enclosure. A 1.5 meter #6 stranded copper
wire terminated with a ring terminal is provided with the microBTS for linking the enclosure to
an earth ground source.
2.9 Cooling
Passive cooling of the electronic assemblies is provided by conducting excess heat from the
internal electronic components to the aluminum enclosure. The heat is then dissipated to the
outside air by radiation and convection air flow over the enclosure’s external cooling fins. An
alarm is generated if a high temperature condition occurs within the enclosure.
2.10 User Interface
The microBTS user interface consists of the connectors, grounding lug, and LED that are
provided on the exterior of the enclosure. The microBTS user interface points are indicated in
Figure 2 and described in Tab le 1.

thoroughly to remove and dirt, dust, or foreign matter. Shake the paint bottle until thoroughly
mixed and then apply a light coat of paint to the damaged area using the small brush attached to

When the installation is complete, refer to the applicable publications for the system turn-up and
test procedures. To verify that the microBTS is ready to be placed into service, place the AC
breaker in the closed (on) position and observe the LED indicator light on the bottom of the
enclosure. The LED indicator should turn red immediately following power-up. The LED will
continue to stay red for up to 30 minutes following the initial power-up during which time the
microBTS will synchronize with an external clock source. When the microBTS timing has been
synchronized, the LED will turn off.
