Abstract

This paper deals with the modelling of mobile signals propagated through, around and reflected from buildings and other structures common to a city in the near field region. In the modelling, upper microwave and lower mm wave propagation data available in the open literature at frequencies 9.6, 28.8 and 57.6 GHz are considered. A strong interference zone has been noticed in the near field region from 0.2 to 0.6 km. Three methods are proposed to predict the path loss to validate data in the near field region. The results predicted from the simulations are well compared with measured data. The standard deviations of the predictions made by these models in the near field region are within 7 dB at all three frequencies.
