IEEE 802.16e WIMAX (Worldwide interoperable Microwave Access) is the upcoming wireless system which can offer high speed voice, video and data service up to the customer end..It offers both LOS&N-LOS wireless communication. By using WIMAX Technology we can overcome the limitation of short coverage area, lack of security and low data rate. The aim of this paper is the performance evaluation of a...

The WIMAX technology based on air interface standard 802-16 wireless MAN is configured in the same way as a traditional cellular network with base stations using point to multipoint architecture to drive a service over a radius up to several kilometers. The range and the Non Line of Sight (NLOS) ability of WIMAX make the system very attractive for users, but there will be slightly higher BER at...

Mobile worldwide interoperability for microwave access (Mobile WiMAX) based on IEEE 802.16e is a standard designed for metropolitan area networks (MAN) that cover an area wider than that covered by local area networks. Commercial WiMAX services are already available in some countries and regions. Services in Japan are scheduled to start in 2009. Mobile WiMAX supports “one-cell frequency reuse,”...

The main objectives of this paper is to examine the performance of the wireless broadband infrastructures and their support for Triple Play services under different separated scenarios by using OPNET Modeler 14.5. This simulation network uses several features to study the performances of WiMax on Triple Play services, 3.5GHz band is chosen in our studies because it is widely used band all over ...

Worldwide Interoperability for Microwave Access (WiMAX) specified by IEEE 802.16 supports Wireless Metropolitan Area Network (WMAN). In the environment of WMAN the mobile client has high mobility as it moves from the coverage area of Serving Base Station (SBS) to Target Base Station (TBS). Handoff is one of the Quality of Service (QoS) parameter in the WiMAX network which supports mobility and ...

This study considers the different UWB antenna designs with band notch characteristics. Different antennas designs to reject interference from WLAN, WiMAX, DSRC, and HIPERLAN/2A are considered and listed in table. Index Terms – UWB, WLAN, WiMAX, HIPERLAN/2A.

Broadband wireless networks have received a lot of research and development in the last few years. This network technology offers data rates in the 100s of Mbps with a range of tens of miles. The IEEE have developed the 802.16 standards, also called WiMAX, to provide specifications for these networks. Currently, there are over 500 deployments of WiMAX in over 140 countries with millions of subs...

The IEEE/802.16/WiMAX new technology provides wireless wideband access both in rural and urban areas. While the 802.16/WiMAX architectures are already defined in standards and many studies exist, research is still needed, on integration of this access in end-to-end architectures. This paper proposes a flexible architecture for management and control of the IEEE 802.16/WiMAX, used for access to ...
