Static WCDMA system simulator for indoor environments
K. Tigerstedt, Kari Heiska · 2002
A static system simulator has been developed for indoor purposes specifically. Based on an existing macro/microcell simulator, this new indoor simulator includes novel approaches for planning a WCDMA network using picocells in the 3D environment of a multi-storey building. A new computation-efficient propagation model for indoors was also developed, allowing for fast modification of the network plan and requiring only bitmap images of the building floorplan as input. Using some on-site measurements, the tunable parameters of this zone-based propagation can be set. The simulator allows modelling of typical indoor radiator solutions, such as omnidirectional and directional antennas and also radiating cables. Special emphasis is also put upon graphical presentation of results on a floor-by-floor basis, allowing for identification of base station (BS) dominance areas, soft handover areas, link loss displays, loading of BS etc.
