This chapter addresses the issue of a cross layer radio resource management in IEEE 802.16 metropolitan network and focuses specially on IEEE 802.16e-2005 WiMAX network with Wireless MANOFDMA physical layer. A wireless bandwidth allocation strategy for a mobile WiMAX network is very important since it determines the maximum average number of users accepted in the network and consequently the pr...

WiMAX: An analysis of the existing technology and compare with the cellular networks. Abstract Broadband access technology has significant influences in the telecommunication industry. Worldwide interoperability for microwave access (WiMAX) is a broadband wireless technology which brings broadband experience to a wireless context. There are two different types of broadband wireless services. On...

In recent years, the integration of Worldwide Interoperability for Microwave Access (WiMAX) and Ethernet Passive Optical Network (EPON) has become one of the most promising broadband access solutions. The EPON network provides tremendous bandwidth while the WiMAX network can support mobility. Integration of PON and WiMAX combines the best of both technologies. However, the integration requires ...

Mobile Worldwide Interoperability for Microwave Access (Mobile WiMAX) is useful as next-generation wireless broadband access technology based on OFDMA. For it to proliferate, the radio interference between WiMAX, which is operated on the 2.3 GHz and 2.5 GHz bands, and WiFi/Bluetooth, which is located on the Industrial Scientific and Medical (ISM) band (2.4 GHz), needs to be resolved. Fujitsu ha...

Mobile Worldwide interoperability for Microwave access (WiMAX), IEEE 802.16e is a promising solution that provides ubiquitous wireless access with high data rates, high mobility and wide coverage. The main issue in mobile WiMAX networks is managing user mobility. Queues associated with the arriving packets should have enough bandwidth to meet the requirements; else the Handoff Call Dropping Pro...

IEEE 802.16e mobile WiMAX standard provides a promising technology for broadband wireless access. Owing to the limited bandwidth resource and increased data-rate requirement, some sort of mechanism is essential to achieve good spectral efficiency and to better manage the limited resources of bandwidth. Link adaptation technique helps in meeting out these demands and has now emerged as one of th...

A dynamic bias technology is proposed to meet linearity standards at high-power levels and simultaneously reduce power consumption at low-power output levels for a mobile WiMAX terminal application. The dynamic bias circuit induces voltage via the current from the source port of the final active stage, and makes the bias operate the PA dynamically as the output power level is increased. The fab...

Recently, there have been numerous standardization activities for making the IEEE802.16e system highly effective in supporting mobile users based on orthogonal frequency division multiple access (OFDMA) with Time Division Duplex (TDD) mode in (IEEE Standard 802.16e-2005, 2005) and (WiMAX Forum). Standardization activities of the IEEE802.16e system were completed in 2005, and currently enhanceme...

In this paper, we propose an end-to-end network architecture based on Worldwide Interoperability for Microwave Access (WiMAX) over Ethernet Passive Optical Network (EPON) and present a security framework adopting both RSA and Extensible Authentication Protocol (EAP) authentication. We also introduce handover scenarios in the integrated network and propose corresponding handover schemes, for whi...
