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 ...

The latest technology that provide broadband access with large coverage area is Worldwide Interoperability for Microwave Access (WiMAX), Since Mobile WiMAX has an important advantage to serve large coverage areas per base station, Mobile WiMAX has become a popular technology for handling mobile users. As we know that for serving a large number of Mobile Users in practice requires an efficient h...

WiMAX has been introduced as a competitive alternative for metropolitan broadband wireless access technologies. It is connection oriented and it can provide very high data rates, large service coverage, and flexible quality of services (QoS). Due to the large number of connections and flexible QoS supported by WiMAX, the uplink access in WiMAX networks is very challenging since the medium acces...

The modern wireless systems are required to have high voice quality and data rate. Since our concern is most with scattering environment, antenna diversity is a practically effective and widely applied technique to reduce the effect of multipath fading. In this regard, Multiple Input Multiple Output (MIMO) techniques are an essential part of the IEEE 802.16e-2005 specifications, which form the ...

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 ...

Security support is mandatory for any communication networks. For wireless systems, security support is even more important to protect the users as well as the network. Since wireless medium is available to all, the attackers can easily access the network and the network becomes more vulnerable for the user and the network service provider. Worldwide Interoperability for Microwave Access (WiMax...

Wired WLAN (Wireless Local Area Network) technology emerged as the most widely used network. is suitable for those who need internet. By using will be found various advantages its users. Likewise with WiMAX (Worldwide Interoperability Microwave Access) wireless technology, basically has a function similar to WLAN, but certain small differences. can cover one local area, in contrast which metrop...

WiMAX (Worldwide Interoperability for Microwave Access) embodies the IEEE 802.16 family of standards that provisionwireless broadband access.With the IEEE 802.16e−2005 mobility amendment, WiMAX promises to address the ever-increasing demand for mobile high speed wireless data in fourth-generation (4G) networks. WiMAX market studies continue to project increased subscriber growth rates and plann...
