BS-240/BS-241/BS-240XL

Minimal footprint, maximum performance

BS-240/241/240XL is the new future-proof evolution of

Siemens’ BTS hardware. Highlights are configurations with

up to 24 TRX, significantly reduced volume per TRX, and a

future-oriented platform for new GSM features. Siemens’

latest base stations are already prepared for UMTS.

We designed the new Base Station BS-240XL to meet

customer requirements and at the same time provide space-

saving solutions for common sites for GSM and UMTS.

Product Profile

Increasing demands for higher

capacity are met by

BS-240/241/240XL through

reduced volume and an

expanded number of 24TRX in

2 or 3 racks with a modularity

of 8 TRX (resp. 12 TRX) per rack.

This also makes the

BS-240/241/240XL a powerful

dualband base station for

GSM900 and GMS1800, as well

as for GSM900 and GSM1900.

A full spectrum of combining

equipment means high output

power and a minimized number

of antennas for all cell

configurations.

The BS-240/241/240XL boasts

high receiver sensitivity and

thanks to its small footprint lets

operators save on infrastructural

expenses.The optional SDMA

(switched beams) is planned for

operators with limited frequency

spectrum.The modular archi-

tecture and the flexible internal

structure with data rates of up

to 2MBit/s enables the

BS-240/241/240XL to provide

new GSM features such as

EDGE.This platform ensures

that network evolution is as

smooth as possible.The use of

latest technology reduces power

consumption and improves

reliability.

Customer Benefits

■ Compatibility with existing

SBS ensures easy integra-

tion into the already installed

infrastructure

■ Possible site configurations

of up to 72TRX/site for

increasing capacity require-

ments

■ Highest reliability thanks

to redundancy for all core

modules

■ Reduced investment costs

due to integrated Abis cross

connect (8 PCM lines)

■ Fast network rollout:

approximately 50% fewer

sites required due to

superior RX sensitivity and

high output power

■ No service interruption

for rack extension orTRX

exchange
