Interference by Noise

Wanted field strength F d Minimum field strength F min

Noise level F N

Minimum field strength (C/N): It is a minimum field strength level which is necessary to fulfil the signal quality for coverage.

Usable field: Summation of the nusiance fields of the interfering tansmitters according to a certain summations algorithm (maximum, simplified multiplication, ...) It is the fieldstrength value which is usable by a possible new site just to fulfill the condition of coverage (C/I>0) by the existing interferer situation.

Network Processor


The Network Processor • produces network-wide results out of the singlecell-based results • allows to analyse the radio network

BS1

• allows to simulate changes of the network parameter

BS2

• allows to simulate changes of the network design • allows to optimise the radio network

BS3

• allows to plan the future roll-out phases • produces statistics on the selected results

each Service needs an own service-specific Network Processor  2005 by LS telcom AG



Network Processor


many other service-specific results can be processed by a powerful Network Processor, like: • Number of Max Sever • Number Best Server • Strongest Interferer • Level of Strongest Interferer • Coverage Probability • Coverage Reserve


• Power Difference • Assignment Probability • Handover Zone • Requeired Channels • Coding Sheme Area (GPRS) • SFN Level Gain • ...
