2G and 2.5G Networks

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

Prediction of the max. received power in downlink 


Figure: Predicted max received power in downlink
For each pixel (mobile station) the max. received power in downlink from all cells (transmitters) is determined.

This is especially important if the cell assignment is based on the max received power. The value depends only on the max. available Tx power at each transmitter and the path loss between the transmitting antenna and the mobile station. The properties of the mobile station (antenna gain, losses,...) are not considered.

This map is not determined individually fort each MCS/service (because the settings of the MCS are not considered).


As shown below, the result plot can be used to make coverage analysis if a threshold for the received power is defined (in the figure the threshold is -60 dBm). The color of the pixels depends if they are above or below the threshold.
