Abstract :
This paper presents early results from a study to develop wideband 2-dimensional channel models for ISM bands. Wideband measurements were carried out in Oxford, UK at 2.4 and 5.7 GHz, covering a bandwidth of 80 MHz for static outdoor to indoor scenarios. The measurements were targeted to provide impulse responses with angle-of-arrival information, information on correlation between horizontal and vertical polarisation, and information on small-scale spatial correlation. Parameter extraction used for the measured raw data is described. Examples of the results of parameter extraction are presented. The approach to the channel modelling is to model the clustering of multipath components in both time (delay) and space. The statistics of the cluster parameters are fitted against the measured data. A Markov chain model in both temporal and spatial domain is utilised
