IEEE 802.6 metropolitan area networks (MANs) provide an efficient architecture for supporting wireless personal communication services (PCSs) over metropolitan areas by interconnecting wireless base stations into personal communication networks (PCNs). They also serve as peripheral gathering networks to transport PCS traffic over a wide area broadband integrated services digital network employi...

Abstract The IEEE 802.16 of standards is known as Worldwide Interoperability for Microwave Access. IEEE 802.16 standard defines Wireless metropolitan area network (MAN). It has been designed to provide high data rate communication in metropolitan area wireless networks. For broadband wireless access is employed for high speed and low cost, in which is easy to deploy, or provides a better altern...

Wireless Fidelity (WiFi) network is based on the IEEE 802.11 standard. Worldwide Interoperability for Microwave Access (WiMAX), based on IEEE 802.16, is a standard with similar principles. The main advantage of WiMAX over WiFi is that it covers larger areas and has higher data rates. WiMAX network operators provide WiMAX subscriber units that enable connection to the metropolitan WiMAX network ...

The use of geographic information systems in determining transit service areas has not progressed far beyond simple buffering operations even though there is widespread capability to analyze network walking distances in conjunction with demographic, cadastral, and land-use data sets. This article presents a method for determining the population with walking access to bus stop locations using th...

The National Institute of Standards and Technology (NIST) has developed a number of complete fiber-based high-speed quantum key distribution (QKD) systems that includes an 850 nm QKD system for a local area network (LAN), a 1310 nm QKD system for a metropolitan area network (MAN), and a 3-node quantum network controlled by a network manager. This paper discusses the key techniques used to imple...
