Abstract:
IEEE 802.16 standard defines the wireless broadband technology called WiMAX. When compared to other wireless technologies, it introduces many interesting advantages at physical (PHY) and media access control (MAC) layers. The WiMAX technology based on air interface standard 802.16 wireless metropolitan area network (MAN) is configured in the same way as a traditional cellular network with base stations using point to multipoint architecture to drive a service over a radius up to several kilometres. The range and the non line of sight (NLOS) ability of WiMAX make the system very attractive for users, but there will be slightly higher bit error ratio (BER) at low signal to noise ratio (SNR). WiMAX networks incorporate quality of service (QoS) mechanisms at the MAC layer. The problem of assuring QoS is basically that of how to allocate available resources among users in order to meet the QoS criteria such as delay, jitter and throughput requirements and how to achieve the optimal usage of resources to maximize throughput and to minimize power consumption while ensuring system scalability. In this paper, we make practical measurements of the WiMAX- system’s QoS performance behaviour of the unsolicited grant service (UGS) and real time polling (RTP) classes.
