WESTELL.COM General Description Westell’s Twin Variable Gain 700 MHz Upper-C Tower Mounted Amplifier (TMA) with AISG Re-inject output is an ideal solution for optimizing LTE cell site performance by improving base station receiver sensitivity. With the TTMAV-700C, 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 that supports one full sector. To support all types of deployment environments, the gain of the TTMAV-700C can be set in 1 dB increments from 3 dB to 13 dB, using AISG 2.0. Additionally the TMA supports control of Smart-Bias-T RET Antennas via AISG re-injection on the Antenna port eliminating the need for a separate AISG cable; thus improving reliability and costs.
