Abstract
For the first time, this paper presents both static andmobile signal strength measurements made for a bodywornUWB radio channel in a 49m2 hospital environment usingRF-over-fibre technology to eliminate unwantedelectromagnetic interference effects associated with the use ofRF co-axial cables. The results show that received signalstrength values depend significantly on whether the transmitand receive antennas are in relative LOS or NLOS, with LOSvalues being higher than the reference value and NLOS beingless than the reference value. For mobile tests, LOS conditionstended to be either Rice or Gamma distributed with NLOSLognormal distributed. For static conditions, signal strength isalso dependant on user mode, with the difference betweenstanding and sitting in the same location being up to 10.66dB.
