On the capacity of 60 GHz wireless communications

Abstract

In this paper, we determine the channel capacity of 60GHz wireless communications over additive white Gaussian noise channels. The channel capacity with phase shift keying (PSK) is investigated under FCC power constraints for the unlicensed 59– 64GHz radio spectrum. It is shown that the capacity of 60GHz wireless communications is a function of distance and signal to noise (SNR) ratio, which demonstrates a fundamental trade-off for system design. The 60GHz system capacity is also compared to the capacity of Ultra Wideband radio system.
