BWC-TMA-700C-VG Tower Mounted Amplifier
BWC-TMA-700C-VG Tower Mounted Amplifier ® Variable Gain 700 MHz Upper-C TMA with AISG Connector Overview Westell’s Variable Gain 700 MHz Upper-C Tower Mounted Amplifier (TMA) with an AISG connector is an ideal solution for optimizing LTE cell site performance by improving base station receiver sensitivity. With the BWC-TMA-700C-VG, operators will see fewer failed connection attempts, fewer context drops, expanded coverage area (critical for VoLTE), and increased uplink data throughput; all in a compact, highly-reliable, and cost-effective package. To support all types of deployment environments the gain of the BWC-TMA-700C-VG can be set in 1 dB increments from 3 dB to 13 dB using AISG 2.0. The AISG connector on the bottom of the unit allows operators to control RET antennas via a jumper cable from the TMA to the antenna, thus improving reliability and reducing cabling costs.
