粘的乱了,下doc看吧,有点乱,我也没编辑了。
EDGE:
BTS power consumption
The BTS power consumption depends on the input voltage, the ambient temperature and the traffic load. The following values are calculated for operational configurations with a 2-way uplink diversity (all TRXs transmitting at full power in all timeslots):


Site configuration
Combining method
Power consumption (W)
  Frequency band

1800
1900

MCPA:
BTS power consumption
The total BTS level consumption is comprised of the following ‘blocks’:

Figure 14: BTS level power consumption ‘blocks’
(*) Fixed consumption excluding the impact of variable fan speed
(**) Varies depending on "per TRX power" setting and the number of active time slots
The total BTS level power consumption can be estimated by adding up these blocks:
    ESMx consumption (including the FIxx transmission card)
    RF Module idle consumption (with no RF output)
  • Branch (or pipe) level consumption

The branch level consumption varies for different configurations and depends on factors such as "per TRX power" setting and number of active time slots.
BTS heat dissipation can be estimated by subtracting total TX power from total BTS intake power.
The BTS power consumption figures given below are measured under the following conditions:
    Based on the measurements taken with random units of ESMB, ESMC, FXDA, and FXEA modules of version A.101 with EX3.1 MP1.0 BTS SW.
    Power Level (PL) =0 (maximum power), room temperature, dedicated 2G mode with GMSK modulation, 54 VDC power supply, Optimized Cooling profile (default).
    Measurements done in BTS Network Mode (under BSC control), TCH TRX(s) activated via 2G Flexi BTS Site Manager menu ‘Test’ and ‘TRX Continuous Transmission’ (activates all timeslots).
    The RF Module idle consumption measured when BTS (sector) or BCF object is locked on BSC.
  • Fans rotating at typical speed at room temperature. The maximum fan speed can increase module level power consumption by 20 W.


The following BTS level power consumption values are an estimate and a tolerance of ±10% compared to a real measured value is expected.
For examples of calculating power consumption or heat dissipation, see table [url=]Examples of power consumption calculations[/url].
Note that the [letters] such as [A] in the table [url=]BTS power consumption[/url], are used for examples given in the table [url=]Examples of power consumption calculations[/url].

Table 25: BTS power consumption

Examples of calculating power consumption using values provided in the BTS power consumption table
Configuration
BTS level power consumption / heat dissipation
1+1+1 BCCH only (60 W, 20 W, 10 W) with 1xFXDA and 1xESMB
Power consumption = [A] + + [C] + [D] + [F]
= 150 + 240+ 155+ 120 + 50 = 715 W
1+3+5 (60 W+20 W+10 W) configuration with 1xFXDA and 1xESMB
Power consumption = [A] + 3X[E] + [F]
= 150 + 720 + 50 = 920 W
1+1+1 BCCH only (3x10 W) with 1xFXDA and 1xESMB
Power consumption = [A] + 3x[D] + [F]
= 150 + 360 + 50 = 560 W
3+3+3 (all 20 W) with 1xRFM and 1xESMB
Heat dissipation = (A + 3xE + F) - (9x20W)
= 920 W - 180 W = 740 W
