This letter presents radio channel measurements and modeling results for the feasibility study of 60 GHz highspeed radio systems in hospital environments. Two possible applications of those systems are considered: real-time video streaming for angiography and for ultrasonic inspection. Channel modeling was performed for the path loss and multipath characteristics of the propagation channel, i.e., the delay spreads. Results revealed generally lower path loss and delay spread values compared to regular indoor office and residential environments. The results indicate that the 60 GHz radio systems operating in hospital environments can provide better signal quality and wider coverage than those operated in regular indoor environments, though increased interference with neighboring cells might be an unfortunate consequence.
