Westell’s tower mounted amplifiers (TMAs), an integral product suite in the cell site optimization solution, provide a cost-effective method for optimizing a cell site’s RF signal performance. A TMA is usually mounted on the top of a cell tower close to the antenna before the long cable run to the eNodeB to minimize signal loss.
The TMAs utilizes a low noise amplifier (LNA) to filter and amplify the uplink signal, extending the range of the uplink signal, providing higher data throughput, and increasing site capacity. The downlink signal is also filtered to minimize unnecessary out-of-band noise. If a power or LNA failure occurs, the TMA keeps the sector active with only slight signal degradation.
