The RRU3008 supports AC and DC
power input modes and performs modulation, demodulation, data processing, and
combining and dividing for baseband signals and Radio Frequency (RF) signals.

l For S1, S2, S3, S4, S5, and S6,
the 8PSK output power is the same as the GMSK output power with the improvement
in the hardware capability.
l For S7 and S8, the 8PSK output
power is the same as the GMSK output power with the optional feature
GBFD-118104 Enhanced EDGE Coverage enabled.
l For the RF standards, see EN 301 502

2.5 Power Consumption
l TOC refers to the output power at the
duplex port on the BTS.
l The
typical power consumption is measured with a 30% load and power control and DTX
are enabled. The maximum power
consumption is reached when the base station works with 100% load.
