5 GHz indoor channel characterization: measurements and models

The advent of the HIPERLAN standard in Europe and the emergence of the U-NII bands in the USA allow the development of high bit-rate (>20Mbps) indoor wireless products at 5 GHz. The home is a fertile application ground for such technology. This has prompted the need to investigate the domestic indoor wireless propagation environment at 5 GHz. From measurements in houses, two empirical models were proposed to describe the path loss variation with distance throughout a house. Both models are based on the log-distance metric. One model is specific to individual rooms in a house whereas the other is a worst-case generalisation for all rooms on a floor.
