The telecommunication industry has been developing at a very fast rate, but data networking service revenue has continued to rise. This paper presents on performance enhancement of the WiMAX system (Worldwide Interoperability for Microwave Access) by using Adaptive Equalizer. WiMAX is an emerging global broadband wireless system based on IEEE 802.16 standards. It is a new wireless OFDM-based te...

<p>The implementations of the microstrip patch antenna for wireless local area network (WLAN) and worldwide interoperability microwave access (WiMAX) are analysed in literature this research. Dual or multiband has played a significant part meeting expectations service quickly developing world communication. Basically, transitory guide, an is device that emits absorbs radio waves. Numerous...

A Mobile Node (MN) continuously moves in heterogeneous networks. When connections need to migrate between heterogeneous networks for performance and high-availability reasons, seamless vertical handoff is necessary first step. Everyone around the world would like to be connected seamlessly anytime anywhere through the best network. When MN changes its point of access technology handoff occurs. ...

In order to reduce the power consumption of a mobile station, IEEE802.16e introduced the sleep mode to extend the standby time of battery-powered mobile stations. However, existing mainstream simulation platforms do not yet support the sleep mode. Since simulation tools play increasingly important role in the design, research of network protocols, products and applications, it is of high import...

Next-generation wireless networks will provide different wireless radio access technologies(RAT) like WiFi, WiMAX and GSM to mobile user. It provide seamless mobility with high speed connectivity. Like for phone calls user preffered UMTS and WiFi hotspot for web browsing. To enable connectivity during handoff, all the available networks need to known by mobile user. When multiple access network...

The telecommunication industry has been through disruptive times, but data networking service revenue has continued to rise. The telecom industry is expected to continue to grow as demand increases for cable and high-speed Internet in previously unserviced locations and as local telephone companies upgrade their lines in response to increasing competition. This paper presents an extended overvi...

WiMAX (Worldwide Interoperability for Microwave Access) is an emerging wireless communication system that can provide broadband access with large-scale coverage. Since 2001, WiMAX has evolved from 802.16 to 802.16d standard for fixed wireless access and to the new IEEE 802.16e (Mobile WiMAX) standard with mobility support. The importance of IEEE-Standard 802.16 WiMAX is growing and will compete...
