Measurement and Modelling of Emergency Vehicle-to-Indoor 4.9 GHz Radio Channels and Prediction of IEEE 802.16 Performance for Public Safety Applications

Work reported in this paper contributes to the characterisation of 4.9 GHz radio channels in a scenario in which emergency vehicles are parked outside a building and operate as a communications centre for communications with rescue crews and equipment inside the building. Transmission loss, rms delay spreads, equivalent CW envelope fading characteristics, and frequency correlation characteristics are reported for the measured channels. Achievable IEEE 802.16 performance on the measured channels is also predicted, using simulations based on time series of 50 Mchps PN channel soundings.
