2G and 2.5G Networks

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

Prediction of Serving Cells (Best Server) 


Figure:  Best Server Map (Cells)
Each pixel (representing a mobile station) is assigned to a cell (i.e. transmitter). This cell is the serving cell for the pixel and all mobile stations at this location.


The cell assignment (best server assignment) can be made with two different algorithms:
  • Power based assignment: Max Power received in downlink
    The power received at the mobile station (pixel)  is computed for each transmitter (cell). The pixel is assigned to the cell with the highest received power.
  • Geometrical assignment: Aperture of antenna 
    For each antenna an aperture can be defined. All pixels within this aperture are assigned to the cell. If the pixel is lcoated in two apertures, the assignment is made to the transmitter with the smaller distance.
Of course it is also possible for the user to add own algorithms for cell assignment via an open DLL interface.

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
