1.2 microBTS Description
The microBTS, supports or provides the following basic functions:
• Supports GSM/AMR voice traffic and GPRS/EDGE data traffic via four TRX units
• Supports OMC-R functions including provisioning, alarm management, and performance
management
• Supports IP back haul for voice and data traffic and OMC-R communications
• Provides Power Over Ethernet (POE) to the IP back haul device
• Provides an RF interface (antenna port) for the base station remote antenna
• Provides an RF interface (antenna port) for the GPS or Network Listen antenna
• Accepts AC power input
• Provides a visual indication of unit status
1.2.1 Primary Components
The microBTS is a fully integrated base station solution that includes the following: radio
transceivers, 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 mois-
ture, and provides passive cooling. The internal components are not user replaceable or
accessible. The base station antenna cable connector, IP back haul connector, AC power con-
nector, 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.
1.2.2 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.
1.2.3 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
