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.

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.

Constructing network by using SDR-based Base Station averagely saves single site’s energy by over 40%.
