Abstract

A system for narrowband propagation measurements at 1700 MHz comprising a portable transmitter and two stationary receivers is presented. With this set-up, simulcast is used, and the receivers sample the same carrier frequency. The measured field-strength values are recorded in a laptop-type PC, together with information from the transmitter including sample number and location. The system allows investigation of propagation losses, shadowing due to body effects and different diversity schemes since the recorded values can be identified and compared owing to the transmitted information. The first results show how the fading statistics change when the person carrying the portable transmitter disturbs the radio path
