The sum of each TRX configured maximum output power is bigger than PA maximum output power.

In the area with little traffic, BCCH carrier power configuration can be appropriately added by taking use

of dynamic power, and the remaining power is dynamically real-time shared among all TCH carriers to

enlarge coverage and reduce site quantity.

Networking Mode Saving Energy Consumption

PA module adoptes Doherty, DPD and multi-carrier PA, increasing overall efficiency to over 20%.

RRU is installed close to antenna, saving feeder loss. For the same coverage requirement, it reduces RF output power, hence lowering power consumption.

It supports some latest energy saving technologies such as intelligent voltage adjustment, carrier priority control and RRU module shutdown.

RRU adopts natual cooling system, BBU features in low power consumption and concentration which requires less equipment room and greatly reduces corollary equipments and air-conditioner’s power consumption.
