Product Profile

Increasing demands
demands forfor higher
capacity are met by BS-240/241
through reduced volume and an
expanded number of 24 24 TRX in

3 racks with a modularity
modularity of 8 TRX
per rack.This also makes the
BS-240/241 a powerful dualband
base station
station for
for GSM900 and
GMS1800,
GMS1 800, as well
well as for
for GSM900
and GSM1900.

A full spectrum of combining equip-

A future SDMA option is planned.
The modular archite

cture and the
flexible internal structure with data
rates of up to 2MBit/s enables the
BS-240/241 to provide new GSM
features such as EDGE.This platform
ensures that network evolution is as
smooth as possible.The use of latest
