Locally Coherent Ultra-Wideband Radio Channel Model for Sensor Networks in Industrial Environment

We describe a new transfer function model for the static ultra-wideband (UWB) radio channel in industrial indoor environments for SPIN (sensor, positioning, and identification network) applications. The model addresses propagation between one or more transmitter and one or more receiver positions. It is locally coherent, i.e., it accounts for small scale displacements of transmitter and receiver. It is a geometry-based stochastic channel model which combines quasi-deterministic and purely stochastic components. The environment is represented by a set of scatterers which describe the interior structure of the building. Modelled quantities are the transfer functions pertaining to transmission between the transmitter and receiver positions, the corresponding set of paths, including directions of arrival at the receiver, individual path gains and delays. Parameters derived from 3-11 GHz measurements in an industry-type hall are given
