Advanced Equipment Features Reduce Cell Site Power Consumption - Distributed BTS

Energy benefits from Remote Radio Heads (RRH) include:

Near zero dB feeder loss with RRH mounted close to the antenna (compared to 3dB loss with power amplifier installed at ground level) halve the energy loss

Elimination of air conditioning equipment
