“…However, recently, Zaka et al found that the packet size can deeply influence the throughput performance for non-real-time unicast services in WiMAX [7]; Zhu et al found that the variation of packet size has also an impact on the performance of real-time unicast services over wireless channels [8]. Inspired by these findings, we address the following issue here: how the Variable Packet Size (VPS) influences the throughput performance of the delay bounded general architecture for RWM services?…”

To satisfy the reliability of real-time wireless multimedia multicast services, the existing erasure error correction schemes usually assume that the packet size in transmissions is fixed. However, recent studies have shown that Variable Packet Size (VPS) can deeply influence the performance of unicast wireless services. Accordingly, using a delay-limited general architecture of EEC for real-time wireless multicast, this paper proposes an Adaptive Hybrid Error Correction (AHEC) scheme with VPS. Comparing with the AHEC schemes with fixed packet size, the analysis results show that the AHEC with VPS scheme can improve the throughput by about 10% in some cases.

This chapter presents a theoretical and experimental analysis of the electromagnetic signal propagation between a base station and a subscriber station in an urban setting using the IEEE 802.16d standard and test bed results, which are then compared to Ergeg’s (1998) modified version of the Hata-Okomura (1980) mathematical propagation model. The experimental results of the measurements are similar to the model using the type terrain Category B (Suburban). Additionally, under experimental conditions, equipment with technology IEEE 802.16d and IEEE 802.16e were used to analyze delay and throughput while data, voice, and video was transmitted. The tests show that delay is acceptable for Fixed WiMAX, although it is barely adequate for Mobile WiMAX. As far as throughput is concerned, the average rate is adequate to support applications that include data, voice, and video.
