The history of WiMAX: a complete survey of the evolution in certification and standarization for IEEE 802.16 and WiMAX

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 3.5GHz 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

Compact planar inverted-F antenna for WiMAX application

This paper has focused on the development of multi-band planer inverted-F antenna for use in the three bands WiMAX application. Four slots have been added on the radiated patch to give the required three bands for the WiMAX 2.6, 3.6 and 5.6 GHz, the effect of each slot has been discussed. Both simulated and measured results have been presented

Interpretation of IEEE 802.16e (WiMAX)

The development of 802.16 standards for Broadband Wireless Access technologies was motivated by the rapidly growing need for high-speed, ubiquitous and cost-effective access. The limitations of conventional Broadband wireless access have been overcome with the scalable features of WiMAX. The aim of this paper is to analyse all compulsory features of the WiMAX OFDM physical layer specified in IEEE 802.16e. This paper gives an overview about the WiMAX standard and studies the performance of a WiMAX transmitter and receiver. This is done in order to study the WiMAX network practically. WiMAX network is implemented and analysed in great detail with the help of simulation results. Simulation is performed in the Matlab simulink

An identity aware wimax personalization for pervasive computing services

Mobile Internet access is becoming more and more pervasive in the new 4G scenarios, where WiMAX is to play a crucial role. WiMax has advantages when considering both energy consumption and bandwidth, when compared with HSDPA and LTE. However, we have found some limitations in IEEE 802.16 security support, which may limit authentication and authorization mechanisms for ubiquitous service development. In this article we analyze weaknesses and vulnerabilities we have found in WiMAX security. WiMax, with the adequate identity management support, could be invaluable for developing new pervasive computing services. We propose the introduction of identity management in WiMAX, as a pervious step to the definition of identity aware WiMax personalization of pervasive computing servicesProyecto CCG10-UC3M/TIC-4992 de la Comunidad Autónoma de Madrid y la Universidad Carlos III de Madri

Desain Band Pass Filter untuk Jaringan WiMAX 3.5 GHz

The development of Broadband Wireless Access (BWA) today, not only the connections that are needed, but also speed internet access and large capacity. One of the BWA technology is currently used in IEEE 802.16d WiMAX standard. IEEE 802.16d WiMAX standard using a frequency of 3.5 GHz. Indonesian satellite using the same frequency with the frequency of WiMAX. To avoid interference between WiMAX and satellite receivers need to filter WiMAX. Band pass filter is present as a solution to overcome the problem of interference between WiMAX and Satellite. In this final report discusses the design of bandstop filter circuit consisting of components - namely passive components, inductors and capacitors. Responses were used in this design is the Chebyshev response for Chebyshev response can result in a high degree of steepness of the passband to stopband

The impact of organisational culture on WiMax adoption by Saudi SMEs

Although there is some research that examines Worldwide Inter-operability for Microwave Access (WiMax) adoption, the role of the organisational culture by Small and Medium Enterprises (SMEs) has not been studied in the context of the Kingdom of Saudi Arabia (KSA). This paper presents the outcome of a study carried out to examine the impact of organisational culture on the WiMax adoption by SMEs in the KSA. Based on Cameron and Quinn's Organisational Culture Assessments Instrument (OCAI), 63 questionnaires were distributed to different SMEs in Saudi Arabia. The results showed that there is a relatively low level of WiMax adoption by Saudi SMEs. Findings stated that Saudi SMEs are dominated by the clan culture where people are less innovative than the people in adhocracy culture

A business planning framework for WiMAX applications

Mobile networking refers to wireless technologies which provide communications between devices. Applications for mobile networking have a broad scope as they can be applied to many situations in either industrial or commercial sectors. The challenge for firms is to better match market-induced variability to the organizational issues and systems necessary for technological innovation. This chapter develops a business planning framework for mobile networking applications. This framework recognises the fluidity of the situation when trying to anticipate and model emerging wireless applications. The business planning framework outlined in this chapter is a generic model which can be used by companies to assess the business case for applications utilizing mobile networking technologies
