Abstract

Propagation modeling is an important component of system design and helps to avoid surprises when the actual service begins in the case of wireless systems. Testing of various available models with the experimentally generated data helps to identify the suitable model which can be deployed for the design of future generation of mobile communication systems. This requires raising of new data sets which can be achieved by conducting experiments. With this objective the present study reports the narrowband signal level measurements of 11 GSM base stations in the urban, dense urban and suburban regions of Delhi in northern India. Comparison of the observed data has been carried out with electromagnetic models like AWAS and other empirical models like ITU-R, Cost 231 Hata, Walfisch-Ikegami and Dmitry. Based on the comparison mean prediction error and standard deviations have been deduced. High path loss exponents close to the base station were observed and AWAS electromagnetic code and ITU-R methods reported good agreement with the observed results compared with other methods.
