700MHz Tower Mounted Amplifiers
As operators roll out Voice-Over-LTE (VoLTE) services, they need to deliver the high quality voice services that customers have come to expect with no interruptions in service. This can be accomplished by optimizing the uplink signal from the user device with tower mounted amplifiers, ensuring seamless VoLTE coverage while maintaining the high data throughput needed to deliver an optimal user experience.
Tower mounted amplifiers (TMAs) are increasingly being deployed in low band frequencies such as 700MHz as LTE is uplink-limited – and VoLTE underlines this limitation even further. The LTE system takes advantage of the added uplink gain provided by a TMA, reducing the transmitted power of all mobile devices in the cell. This reduces the overall interference that mobile devices generate in the uplink spectrum.
The new RFS tower mounted amplifiers include integrated Diplexers and Triplexers allowing operators to share existing antenna and RF feeder infrastructure, while amplifying the uplink signal to increase QoS. RFS TMAs feature the lightest weight and best noise figure in the industry. Proprietary high integration technology makes RFS tower mounted amplifiers extremely reliable, with the highest MTBF.
