A REVIEW ON OVERVIEW OF WORLDWIDE INTEROPERABILITY FOR MICROWAVE ACCESS (WIMAX) INNOVATION AND ITS FUTURE UTILIZATIONS

This paper introduces the elements of the Worldwide Interoperability for Microwave Access (WiMAX) innovation and future utilizations of WiMAX. It is a connection oriented wireless network that assures Quality of Service (QoS) for all users in the network. By comparing WiMAX with the popular Wi-Fi, 3G and LTE in the market, it analyzes the current situation and future development trend of WiMAX in terms of the difference in technology and applications. WiMAX will become the most prominent technology for Broadband Wireless Access (BWA). The next generation WMAN networks, using the WiMAX as the core technology is evolving as a 4G technology for providing ubiquitous computing solutions. In not a similar way like wireless LANs, WiMAX networks integrate various QoS mechanism at the Media Access Control (MAC) level for secured service for voice, data and video. The unique architecture of the WiMAX MAC and PHY layer that uses OFDMA to allocate multiple channels with different modulation schemes. A few references have been incorporated towards the completion of this paper for those eager to know in brief about certain
