Wireless local-area networks (WLANs) based on the IEEE 802.11 technology have been widely adopted for private use over the past few years. However, several issues remain concerns for large-scale deployment in corporate environments. Enforcing security and quality-of-service (QoS) has become a fundamental challenge to managing IEEE 802.11-based ente...

The evolution of a fully “Always Best Connected” ABC enabled ‘fourth generation wireless world’, 4GWW, paradigm is addressed in this paper. It addresses the subjective and objective nature of the ABC concept from the viewpoints of the various wireless network ‘players’. ABC definitions corresponding to users’ viewpoints are considered primary and g...
