GSM Cell Planning Flow

ELP 0104  ★★★   

The GSM Cell Planning Flow describes the GSM/GPRS radio network design process, which is focused on fulfilling operator desired coverage, capacity and quality requirements. Coverage: both theoretical and semi-empirical coverage propagation models are presented and the signal strength design concept. Capacity: the concept of congestion and Erlang formula are presented and used for traffic and control channels capacity dimensioning. Quality: co-channel and adjacent channel interference and frequency reuse pattern concepts are presented and used for channel and BSIC planning. Impact of GPRS on the GSM network planning is also discussed. The training includes radio network design case study. The course also presents the in-building cell planning process and the selected radio network procedures essential for the cell planner.
