Tower Mounted Amplifier (TMA´s)
Why you should use a Tower Mounted Amplifier (TMA) in your mobile network
BTS without TMA
Many wireless base stations installed today are experiencing unbalanced uplink and downlink paths. This essentially means that the base station downlink (transmit side) has a much better coverage area than the uplink (receive side). The reason for this is that the typical uplink transmitter is a handheld device with about 1 watt of transmit power while the downlink can transmit with typically 20 watts or higher. Taking into consideration the difference in sensitivity there is an unbalance in the downlink vs uplink coverage area.
BTS with TMA
In this scenario, the receive side performance is improved so that the uplink coverage area equals the downlink coverage area and the link budget equation is balanced. This makes Tower Mounted Amplifier (TMA) one of the easiest and most cost effective ways of balancing the system.
