Abstract
The design of short‐range high‐speed wireless networks for the 60 GHz band requires consideration of factors from a wide range of disciplines. Key system choices that make significant differences to the final cost and performance include the type of antennas, multiple access strategy and channel coding. In this paper we assume a coded orthogonal frequency division multiplexing (OFDM) system providing high‐speed communications between low‐cost terminals over indoor 60 GHz channels that are frequently non‐line‐of‐sight. Under constraints of low transmit power and high path attenuation, we consider two practical options for using multiple low‐cost ‘bond‐wire’ antennas, compared with ideal monopole antennas at each terminal. For specified multiple access and channel coding schemes, we show that a sectorized strategy based on simple 2 element phased arrays can provide substantial benefits in system performance and flexibility.
