5 Introduction <strong>to</strong> Siemens Mobile Networks
New Micro Base Station (eMicro BTS)<br />
The eMicro BTS is a new future-proof evolution<br />
of Siemens BTS.<br />
A new modular highly flexible architecture<br />
enables the new Micro BTS platform <strong>to</strong> support<br />
features which in the past were reserved <strong>to</strong><br />
macro base stations.<br />
Having the same software base it is fully<br />
compatible with Siemens<br />
BS-240/241, BS-20/21/22 and<br />
BS-60/61 products.<br />

3. Benefits of PowerCP<br />
• Increase of Call Processing Performance by fac<strong>to</strong>r 5<br />
• Enough Performance for more than 1 million subscriber MSC => enough<br />
capacity until 2010<br />
• Evolution of proven CP concept: same superior quality and well known<br />
operation and maintenance concept<br />
• Seamless integration in<strong>to</strong> existing platform due <strong>to</strong> compatible interfaces -<br />
only partial HW replacement necessary<br />
• One APS supports PowerCP (CP113E) and CP113C without further<br />
modifications<br />
• Solutions of other providers are based on complete new HW: this requires<br />
severe SW modifications and a new stabilization phase.<br />

D900 the most powerful switch - Keeping the distance<br />
The Siemens D900 <strong>to</strong>day is the most powerful <strong>mobile</strong> system<br />
on the world market<br />
Due <strong>to</strong> evolutionary concept D900 will continue <strong>to</strong> be at the<br />
leading edge<br />
The new Power MSC (SSNC + PowerCP) will be the first real<br />
One Million Subscriber Switch on the market<br />
High capacity switches require even higher reliability which<br />
are both provided by the D900<br />
Futureproof: Clear evolution path <strong>to</strong> GPRS and UMTS<br />
