2G and 2.5G Networks

Planning of 2G and 2.5G (GSM/GPRS/EDGE) networks

Reception Probability (in downlink) 


Figure: Required Tx power at MS lto reach the serving BTS
Based on the prediction of the  SNIR, a reception probability is determined. The Rayleigh distribution is used and depending on the SNIR (in relation to the min. required SNIR defined for the MCS/service) the probability is determined to be above the the min. required SNIR target.

This map is determined individually for each MCS or service. The capabilities of the mobile stations (defined for this MCS or service) are therefore additionally considered (i.e. max. available Tx power in the mobile station, MS antenna gain, fast fading margin,...).

Features

Features of the 2.5G (GPRS/EDGE) module at a glance:

  • Coverage analysis based on accurate propagation models
  • Consideration of downlink and uplink
  • Adaptive coding and modulation schemes (MCS) are supported with individual SNIR targets
  • CoChannel Interference anaylsis
  • Coverage analysis (incl. Fast Fading margin)
  • Capacity estimation
  • Required Tx power in up- and downlink 
  • Multi-Service concept allows user-defined services   
  • Easy handling of the databases
