Abstract

Cross-floor signal propagation characteristics at 434, 862, and 1705 MHz were assessed from measured data in a building similar to a hospital as a first step toward maximizing electromagnetic compatibility (EMC) between wireless radiators within a hospital and medical equipment. Certain transmitter-receiver configurations resulted in 1/r ^d signal attenuation (d=2, and 3<4<4), while other configurations exhibited quasi-constant signal levels over increasing transmitter-receiver separations
