*125.6128.4131.1 As recommended in 3GPP TS 25.104, is measured in
the entire operating band at the antenna connector on the condition
that the channel rate is 12.2 kbit/s and the BER is not higher than
0.001. *: The receiver sensitivity (at the centre frequency) is
measured at the antenna connector provided that the AMR service at
12.2 kbit/s is used and the BER is within 0.001. 2.4 Output Power
Maximum output power = Maximum output power of the PA - Internal
losses. The maximum output power is measured at the antenna
connector of the RF module. One 80 W WRFU supports four carriers
and differentiated power configured for each carrier. Its output
power at the antenna connector reaches 80 W. Table 2-4 shows 80 W
WRFU output power. Table 2-5 shows 80 W WRFU (Optimized) output
power. Table 2-4 80 W WRFU output power Number of CarriersOutput

only the 2100 MHz band class. 2.5 Power Consumption The typical
power consumption is measured with the equipment 40% loaded at a
temperature of 25C. The maximum power consumption is measured with
the equipment 100% loaded at a temperature of 25C. In the 3x1 or
3x2 configuration, one WBBPb4 and one WMPT are configured. In the
3x3 or 3x4 configuration, two WBBPb4 units and one WMPT are
configured. 2.5.1 BTS3900 Power Consumption Table 2-7 BTS3900 power
