A Study on Wimax Network Technology

Jigeesha Joshi, Kanakkumar Yadav

Interest in broadband wireless access (BWA) has been growing due to increase in user mobility and the need for data access at all times. IEEE 802.16e based WiMAX networks promise the best available quality of experience for mobile data service users. Unlike wireless LANs, WiMAX networks incorporate several quality of service (QoS) mechanisms at the Media Access Control (MAC) level for guaranteed services for data, voice and video. 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, delay jitter and throughput requirements. IEEE standard does not include a standard scheduling mechanism and leaves it for implementer differentiation. Scheduling is, therefore, of special interest to all WiMAX equipment makers and service providers. So we can conclude IEEE 802.16(Broadband Wireless MAN) is fast growing wireless broadband networks of the world The combination of Multiple Input Multiple Output wireless technology with IEEE 802.16e-2005 (WiMAX) standard has been recognized as most promising technologies with advent of next generation broadband wireless communications. In this paper we provide an overview and review of WiMAX.
