A Combined Frequency and Time Based Channel Reuse Partitioning Multiple Access Technique for Indoor Wireless ATM Networks
This paper describes a multiple access technique suitable for indoor wireless ATM networks that exploits both frequency division and time division techniques for channel re-use (i.e. FDMA/TDMA). The novel feature of the proposed technique is that co-ordinated, prioritised TDM A is supported for clusters of Access Point’s (AP’s) using measurement based time slot assignments. This has the advantage of easily supporting uneven load distributions and allowing rapid handover between AP’s on the same frequency carrier. The proposed technique can also support bursty traffic efficiently by periodic time slot re-assignment, which is an important consideration for wireless ATM systems. Results are presented of the performance of the proposed technique and are compared with a conventional FDMA/TDMA strategy.
