Adaptive antenna array methods in cellular applications are typically constrained by cost to the basestation. In order to achieve high network capacity, however, both the uplink and downlink channels must be improved; the basestation therefore must make use of reciprocity to transmit minimal interference to interfering co-channel users, while sending maximal power to desired users. In PHS, the primary limitation to reciprocity is channel motion, due either to user motion or environmental motion. This paper introduces statistics to quantify, this motion on a network-wide level. The results show great repeatability and are directly relevant to the assessment of network performance with adaptive array antennas.
