There is a powerful trend toward seamless mobility in the wireless industry where mobile professionals today and eventually all consumers in the future will want to communicate and be able to do their daily business anytime, anywhere. As a result, there is real demand for ubiquitous connectivity between a wide variety of mobile devices and access technologies, which (at least for now) include wireless WANs and wireless LANs. Roaming and communications between these technologies is therefore a must for seamless mobility to occur. To realize the potential of seamless mobility and ensure continued profitability, service providers have to focus equally on WLAN implementations as they do on their cellular WWAN networks. Wi-Fi and traditional wireless services are adjuncts that can co-exist and succeed together and provide consumers what they want and when they want it. Customers will use these technologies for different reasons and at different times. The 2.5G and 3G technologies such as PRS, EDGE, CDMA 1XRTT and CDMA 1xEV-DO will be used for applications requiring instant gratification and bursty data: e-mail, calendar access, text messaging and MMS among others. But wireless LANs will be used in specific locations where users need access to their corporate files and Intranets. The talk will focus on 3G's business and technical shortcomings and how how service providers can take advantage of WLAN deployments to make up for 3G's revenue shortfall. This talk will also cover the drivers and obstacles that must be addressed to achieve growth in the wireless LAN market such as roaming, billing, security, seamless authentication and handovers.
