although many researchers have written about WiMAX IEEE 802.16e Standard system, it needs more attention and analysis in next generation wireless networks. Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) has become one of the key technologies for the B 3G & 4G broadband wireless communications. This paper is aimed at studying the performance analysis of OFD...

While mobile IPTV services are supported through the mobile WiMAX networks, there must need some guaranteed bandwidth for the IPTV services especially if IPTV and non-IPTV services are simultaneously supported by the mobile WiMAX networks. The quality of an IPTV service definitely depends on the allocated bandwidth for that channel. However, due to the high quality IPTV services and to support ...

ent types and numbers of antennas depending on the required coverage range, direction, and throughput. The CPEs are often engineered differently for indoor and outdoor uses and line-of-sight (LOS) and non-line-of-sight (NLOS) conditions. ITS applications rely on a huge amount of real-time traffic information, which needs a fast, reliable, and easily accessible communication network. WiMAX holds...

High data rates and interoperability of vender devices have made WiMAX a prime desire for use worldwide. WiMAX is based on the IEEE 802.16 standard. IEEE 802.16a, b, c & d versions were updated within three years of the first launch of WiMAX. However, during those early years reports were published that highlighted the security weaknesses of the standard. These weaknesses prompted the IEEE to i...

WiMAX is the next generation technology that offers broadband wireless access over long distances. As WiMAX standards expand from considering a fixed line-of-sight propagation and point-to-multipoint infrastructure high frequency system to a lower frequency non-line-of-sight mobile system, WiMAX is open to more security threats than other wireless systems. This paper presents the different secu...

This paper investigates the suitability of WiMAX/ IEEE-802.16 – based broadband wireless access (BWA) technologies for telemedicine services. Beginning with a brief review of Wireless communication technologies for health and comparison of the basic features of Wi-Fi and WiMAX broadband access technologies, performance of WiMAX physical layer has been evaluated for médical image transmission in...

In the recent years, the web and VoIP services has motivated the development of new broadband access technologies due to the increased demands for faster connection [12]. For the upcoming generation, IEEE 802.16 standard, WiMAX (Worldwide Interoperability for Microwave Access Forum) has become the most potential wireless access technology. WiMAX uses a common MAC protocol to incorporate the set...

Wireless telemedicine, also referred to as mobile health, which capitalizes on advances of wireless technologies to deliver health care and exchange medical knowledge anywhere and any time, overcomes most of geographical, temporal, and even organizational barriers to facilitate remote diagnosis and monitoring, and transfer of medical data and records. In this article we investigate the applicat...

Horizontal developments in communication systems have led to the emergence of new wireless technologies like WiMAX, 3G and 4G. These expansions can provide new opportunities for further advances and exciting applications in particular if we can integrate different technology standards into heterogeneous wireless networks. WiMAX and WiFi wireless networks are two examples of different standard t...

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...
