The indoor-outdoor radio environment

Working within the Mobile VCE a team formed from several leading UK univers ity departments, in association with industry representatives, has been add ressing challenges of the modern wideband radio environment. A focus of the team's work has been to generate new mobile radio data-centric architectur es capable of delivering a high quality of service and a high network capac ity while coping with the little-known outdoor-to-indoor interface. In orde r to address this latter interface, unique propagation data have been captu red and new channel models have been proposed-to describe their behaviour. Finally, performance predictions have been conducted using a new simulation platform.
