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 bottom-
mounted 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.
