MCPA:
BTS power consumption
The total BTS level consumption is comprised of the following ‘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:
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:
For examples of calculating power consumption or heat dissipation, see table [url=]Examples of power consumption calculations[/url].

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

MCPA:
BTS power consumption
The total BTS level consumption is comprised of the following ‘blocks’:
Figure 14: | BTS level power consumption ‘blocks’ |
(**) 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)
- Branch (or pipe) level consumption
RF Module idle consumption (with no RF output)
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.
- Fans rotating at typical speed at room temperature. The maximum fan speed can increase module level power consumption by 20 W.
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.
The following BTS level power consumption values are an estimate and a tolerance of ±10% compared to a real measured value is expected. |
