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%.
