Evaluation of Dual Transceiver Approaches for Scalable WLAN Communications
IEEE 802.11 (Wi-Fi) is a standard feature on smart phones and an alternative to cellular networks for connectivity. Users can surf the Web, make VoIP calls and more from home Wi-Fi networks or public hotspots. At present this type of connectivity is intermittently available with limited mobility support. It is unclear if today's Wi-Fi scales for large number of users. The authors consider the challenges in providing Wi-Fi connectivity to mobile devices on a cellular network-like scale. The provision of quality services which rely on network connectivity, within entertainment parks is considered. Limitations of some existing communications technologies are examined and a number of important problems are quantified. Dual-radio and other solutions to the scalability problem are presented.
