Mobile train radio measurements in urban western India and comparison with some models

Field strength measu rements were conducted in the mov ing trai n in the UHF band in the urban and sub-urban regions of western India. The observed signal levels were compared wi th those predicted from methods like Hata, Wal fish and Bertoni, Uni form theory of diffract ion, Ibrahim and Parsons, Egli and Blomquist and Ladell and suitable methods were ident ified. These studies will be use ful for designi ng future train mobile communication systems and also for assessi ng the interfere nce potential of base stations for electromagnetic interference/electromagnetic compat ibility and spectrum management applications.
