Characterization of radio propagation at 60 GHz channel

The 60 GHz band is of much interest since this is the band in which a massive amount of spectral space (5 GHz) has been allocated worldwide for dense wireless local communications. This paper gives an overview of 60 GHz channel characteristics. A propagation model for indoor wireless communication at 60 GHz is developed using electromagnetic theory. In dense multi path environments, the signal strength is expected to drop off more rapidly due to high penetration loss. An exponential increase in loss with distance in an area populated densely with obstacles has been observed at the lower frequency bands.
