In this paper, the capacity of a cellular Code-Division Multiple Access (CDMA) system operating in the 63-64 GHz band, expressed as the number of users per cell, is evaluated. A propagation model for the 63-64 GHz band is first introduced and discussed. The system capacity is then analytically derived and compared with other CDMA schemes operating in conventional frequency bands (i.e. below 2 GHz). Finally, power requirements are derived and the impact of atmospheric conditions is evaluated. It turns out that the use of 63-64 GHz band greatly increases the capacity of asynchronous CDMA (A-CDMA) systems, and reveals suitable for cellular and personal communication networks (PCNs).

Finally, power requirements are derived and the impact of atmospheric conditions is evaluated.
