Carrier Unit (CU )
GSM 900: minimum guaranteed output power CU = 50 Watt tolerance value: 47.0 dBm
- 47.6 dBm (50 W - 57.5 W); GSM 1800, GSM 1900: minimum guaranteed output power
CU = 34 Watt tolerance value: 45.3 dBm - 46.0 dBm (34 W - 39.5 W).
The mentioned data are guaranteed from Module Factory Test only. The typical output
power at CU output is for:
GSM 900: 47,3 dBm GSM 1800: 45.7 dBm
To verify the typical output power values in field measurements, the tolerance value of
the used measurement equipment, environmental conditions and GSM 05.05 specifica-
tions have to be considered.
Carrier Unit (GCU )
GSM 900: minimum guaranteed output power GCU = 50 Watt (GSMK); GSM 1800:
minimum guaranteed output power GCU = 50 Watt (GSMK).
The GSM 1800 variant of the GCU V2 offers higher output power than the correspond-
ing CU (about 15 Watt): the increased output power of the GSM 1800 GCU V2,
has to be taken into consideration in the radio network planning.
EDGE Carrier Unit (ECU )
GSM 850, GSM 900: minimum guaranteed output power ECU = 63 Watt (GMSK) / 40
Watt (8PSK); GSM 1800, GSM 1900: minimum guaranteed output power ECU = 50
Watt (GMSK) / 32 Watt (8PSK).
The mentioned data are guaranteed from Module Factory Test only.
Rack Configuration
The BS-240/241 family, with 8 transceivers per Rack, which is expandable up to 24
transceivers in 3 Racks and can be supplied in two versions:
– a BS-240 for indoor installation, and
– a BS-241 for outdoor installation (also equipped with integrated link equipment,
Battery Backup and a cooling system).
