The Role of IEEE802. 16e Mobile WiMAX
International Journal of Computer Applications, 2013
A recent technology for the next generation (fourth generation [4 G]) of mobile broadband networks is commonly known as Worldwide Interoperability for Microwave Access (WiMAX) that is designed to provide high bandwidth over long range transmission. IEEE 802.16e mobile WiMAX is accountable for the job of establishing interoperability and conformance between products. This paper provides an brief overview of mobile WiMAX, its features and challenges on the wireless local and Metripolitan Area Network (MAN) standards IEEE 802.16 and IEEE 802.16e.

Most researchers are familiar with the technical features of WiMAX technology but the evolution that WiMAX went through, in terms of standardization and certification, is missing and unknown to most people. Knowledge of this historical process would however aid to understand how WiMAX has become the widespread technology that it is today. Furthermore, it would give insight in the steps to undertake for anyone aiming at introducing a new wireless technology on a worldwide scale. Therefore, this article presents a survey on all relevant activities that took place within three important organizations: the 802.16 Working Group of the IEEE (Institute of Electrical and Electronics Engineers) for technology development and standardization, the WiMAX Forum for product certification and the ITU (International Telecommunication Union) for international recognition. An elaborated and comprehensive overview of all those activities is given, which reveals the importance of the willingness to innovate and to continuously incorporate new ideas in the IEEE standardization process and the importance of the WiMAX Forum certification label granting process to ensure interoperability. We also emphasize the steps that were taken in cooperating with the ITU to improve the international esteem of the technology. Finally, a WiMAX trend analysis is made. We showed how industry interest has fluctuated over time and quantified the evolution in WiMAX product certification and deployments. It is shown that most interest went to the 2.5 GHz and 3.5 GHz frequencies, that most deployments are in geographic regions with a lot of developing countries and that the highest people coverage is achieved in Asia Pacific. This elaborated description of all standardization and certification activities, from the very start up to now, will make the reader comprehend how past and future steps are taken in the development process of new WiMAX features.
Qos Support in Wimax Networks: Issues and Experimental Measurements
The broadband wireless world is moving towards the adoption of WiMAX (the commercial name of the IEEE 802.16 standard) as the standard for broadband wireless Internet access. This will open up a very large market for industry and operators, with a major impact on the way Internet access is conceived today. On the other hand, the emergence of innovative multimedia broadband services is going to impose severe Quality-of-Service (QoS) constraints on underlying network technologies. In this work, after a brief review of the IEEE 802.16 standard, we intend to present an in-depth discussion of its QoS support features. We point out the scheduling algorithm as the critical point in QoS provisioning over such networks, and discuss architectural and algorithmic solutions for an efficient support of multimedia flows.
Through this paper we discusses the architecture, various standards applications and advantages of Wimax provided by developers who introduced the users across a broadband access services to solve barriers to adoption such as interoperability and cist of deployment.
WiMAX Based on IEEE 802.16 Standard- A Survey.
International Journal of Engineering Sciences & Research Technology, 2013
The IEEE 802.16 standard, commonly known as Worldwide Interoperability for Microwave Access (WiMAX) is that the latest technology that has promised to offer broadband wireless access over long distance. This standard was designed to support the bandwidth demanding applications with quality of service (QoS) and a solution to broadband wireless access (BWA) commonly called as (WiMAX), may be a recent wireless broadband standard that has promised high bandwidth over long-range transmission. In this survey we provide an overview of the stateof-the-art mobile WIMAX technology, its development, and (QoS) provisioning
A Review on IEEE 802 . 16 Standards and their Comprehensive Analysis on WiMAX
2017
IEEE protocol 802.16(d) i.e. fixed wimax provides to offer mobile broadband services even at a vehicular speed of up to 120 km/hr. In wimax quality of services provided through scheduling of the different types of service classes like BE, ertPS, nrtPS, rtPS and UGS. Scheduling algorithm are round robin, Weighted Round Robin (WRR) and Weighted Fair Queuing (WFQ). The performance is observed at end-to-end delay, throughput and packet delivery ratio among 2 to 10 number of nodes.
A Survey of Mobile WiMAX IEEE 802.16 m Standard
Arxiv preprint arXiv:1005.0976, 2010
IEEE 802.16m amends the IEEE 802.16 Wireless MAN-OFDMA specification to provide an advanced air interface for operation in licenced bands. It will meet the cellular layer requirements of IMT-Advanced next generation mobile networks. It will be designed to provide significantly improved performance compared to other high rate broadband cellular network systems. For the next generation mobile networks, it is important to consider increasing peak, sustained data reates, corresponding spectral efficiencies, system capacity and cell coverage as well as decreasing latency and providing QoS while carefully considering overall system complexity. In this paper we provide an overview of the stateof-the-art mobile WiMAX technology and its development. We focus our discussion on Physical Layer, MAC Layer, Schedular,QoS provisioning and mobile WiMAX specification.
