Indoor Propagation Modeling for Short Range Devices

The next generation mobile access network system design needs more precise characterization of the radio channel and needs sophisticated propagation models, because of the decreasing link lengths and of higher data rates. In particular, the planning of the coverage in indoor spaces causes design problems without deterministic models. In building propagation measurements, in the frequency band of 433 MHz are presented for narrow band applications, short range devices especially active and passive radio frequency identification (RFID). The propagation model based on 3D FDTD (Finite Difference Time Domain) simulation is proposed and the simulated results are compared with measured ones. The memory and computational time requirements are analyzed for a complex environment.
