Terrestrial mobile communication train measurements in western India
2003
Mobile train radio measurements were conducted in the UHF band in western India with a total distance of 140 km utilizing eight track side base stations in different environments. The observed path losses deduced from signal levels were compared with those deduced from several prediction methods and their standard deviations are discussed. Path loss exponents are derived from signal levels and their variation as a function of distance are also presented. Suitable prediction methods for this region are identified. These studies would be useful for designing future train mobile communication systems in this region, for spectrum management applications and in framing recommendations for the radio communication study group of ITU-R.
