Abstract

The present study reports the field strength measurements of some GSM transmitters in the 900 MHz band located in the urban and suburban regions of Delhi in India. The measured signal levels converted into path loss values have been compared with the losses predicted from models such as Hata, Lee and COST 231 Walfisch and Ikegami. The prediction errors and standard deviations of the prediction errors have been deduced. Based on these results, Lee prediction method has been tuned and new model parameters have been derived. The model comparison is done in terms of statistical parameters such as root mean square error, coefficient of determination and average hit rate error.
