Abstract	Balanced dynamic channel assignment (BDCA) for TDMA radio systems can provide attractive characteristics in dense pedestrian wireless access environments such as wireless PBX or Centrex, but BDCA is less attractive in widespread residential and public access environments, because DCA approaches require frame synchronization of radio ports. BDCA systems make interference measurements at both radio ports and handsets of potential operating channels prior to channel selection, and channel selection is based on the joint measurements. Independent uplink and downlink power control is used to minimize interference. By using BDCA for indoor wireless operation, high capacity and high quality 32 kbps voice circuits can be provided with only two 5 MHz segments of spectrum. If nearby public access systems use adjacent spectrum segments and not the same spectrum segments, the potential interference problems of adjacent radio systems with very different radio port coverage-area sizes can be avoided, but handsets can readily access both types of systems. The performance of an efficient BDCA scheme suitable for indoor wireless operation which is highly compatible with WACS is described in this paper.
