Quality of service in WiMAX Based Broadband Wireless Netwoks Essay

Quality of value in WiMAX ground broadband Wireless Netwoks - Essay ExampleIEEE 802.16/WiMAX-based broadband and restless radio set access is expected to be a significant component in the next generation (e.g., beyond 3G, 4G) wireless systems (Hossain 1). There is a clear shift from telephony to data transfer in wireless networks. In this scenario WiMAX technologies and solutions are collected to play a major role in broadband Internet access and other bring of connectivity. The technology is in its early development phase and there is a widespread research and acknowledgment is going on this field.The issues of quality of service (QoS) are becoming more demanding with the growing demand of the enough media of smartphones and high end gadgets. Users are now more concerned with the QoS of the services with increasing capacity and light upon of wireless technologies. IEEE 802.16/WiMAX standard, which incorporates several advanced radio transmission technologies such as orthogo nal-frequency division multiplexing (OFDM), adaptive pitch contour and coding, and adaptive forward error correction (FEC), is designed to provide broadband wireless capability employ a well-defined quality-of-service (QoS) framework.Though, the adoption of technology is still very limited due to cost ... This write up will discuss the current evolutions going on in the field of WiMAX technologies and issues related to quality of service issues in WiMAX Based broadband Wireless Netwoks along with its, its forms, and the status of its standardization.A specification of the selected topic and the motivation behind this selectionWiMAX and WiMAX-based broadband wireless network offer an alternative to existing wireless and mobile communication technologies. Due to mounting demand for higher bandwidth and better QoS, WiMAX technology has became a subject of needlelike research and debate among researchers and academicians. In this context the selection of the topic Quality of Servi ce in WiMAX-Based Broadband Wireless Networks as a subject of this paper is quite contemporary and may act as a part of ongoing debate over the technology. Existing protocols and solutionsIEEEs 802 LAN/MAN Standards Committee is nigh anonymous with a wireless standards body. IEEE 802.11 set of standards developed by this committee provide a grounding for wireless local area network (WLAN) communications. The IEEE 802 LAN/MAN Standards Committee established a workings group in 1999 for the development of standards specific to Broadband Wireless Access. IEEE 802.16 Working Group on Broadband Wireless Access Standards, as it is know, is responsible for laying down formal standard specifications for broadband wireless MAN/WAN networks. Since the first 802.16 standard was approved in December 2001, three working groups afford been involved for developing standards the group IEEE 802.16.1 is responsible for creating standards for air interfaces in range of 10 to 66 GHz, known as Local Multipoint Distribution Service, group IEEE
