A30808-X3247-L14-2-7618
The architecture of BS-240/241 provides maximum flexibility to develop higher capacity
BTSs with reduced volume and an expanded number of 24 TRXs in 3 Racks with a
modularity of 8 TRXs per Rack. Any operation for rack extension or TRX substitution
doesn't involve service interruption.The provision of a full spectrum of combining equip-
ment allows high power and minimized number of antennas. High receiver sensitivity is
also guaranted.
The modular architecture and the flexible internal structure, 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 the latest technology reduces power consumption and improves reliability;
the reliability is also increased by the redundancy of all core modules. Easy integration
is possible in the already installed sites, for the backward compatibility with existing
SIEMENS SBS systems. High Site efficiency is assured for composite transmit power
with minimal footprint requirements.
Homogenous service throughout the network is assured by common BTS SW running
on all the platforms.
The BS-240/241 primarily consists of:
•
Carrier oriented boards called carrier unit (CU),
•
Core boards (COSA, COBA) and
•
Combining equipment
