—This paper explores the next generation of mobile communication system from different perspectives. A user-centric approach to 4G is considered. We envision 4G as a convergence platform where wide-area (cellular) technology, wireless metropolitan area network (WMAN) and wireless local area network (WLAN) will coexist and complete. Legacy systems, their evolution as well as newly developed acce...

When planning a wireless local area network, there are design issues that need to be considered. In this paper, the fundamentals of planning a wireless local area network are introduced and discussed to highlight the requirements involved. Network constraints, as encountered in the physical environment, are discussed and their relevance to wireless network design is investigated. The paper conc...

Security is the most important aspect considered while using the wireless local area networks. Various techniques have been used in the past to increase the security of WLAN’s while simultaneously making the authentication process faster. The paper presents the review of various such techniques that have been used in the past for the enhancement of the security and achieving fast authentication...

In this paper we examine quality-adjusted prices for local area network (LAN) equipment. Hedonic regressions are used to estimate price changes for the two largest classes of LAN equipment, routers and switches. A matched model was used for LAN cards and the prices for hubs were inferred by using an economic relationship to switches. Overall, we find that prices for the four groups of LAN equip...

Particular attention has been given to propose systems to solve network management tasks, especially for the fault diagnosis and performance management. The construction of such systems requires an intense process of modeling the network environment through interviews with experts in the network management area as well as the use of Artificial Intelligence techniques. The aim of this paper is t...
