Measurements and modeling of propagation losses in buildings at 1.8 GHz and 2.1 GHz

This paper compares the measured results at two frequencies, f=1.72 GHz and f=2.156 GHz, and the simulated results of the radio coverage in an open area office by ray-tracing and statistical tools. The propagation measurements have been performed by transmitting a 1.72 GHz and 2.156 GHz test signal from a fixed antenna to a mobile receiver, and by recording the received signal as a function of receiver location
