Seamless Connectivity Scheme for Heterogeneous Wireless Networks

The demand for the wireless Internet requiring broadband is expected to increase in a dramatic way due to popularity of tri player applications including voice, video, and data transmission. The existing wireless technologies UMTS, WiFi, WiMax, may not satisfy the customer requirements, for many reasons including availability, coverage, cost and most importantly mobility. Each technologies has it is own limitations related to the above characteristics. We present a seamless connectivity scheme for a mobile user, by aggregating different wireless technologies, to make the network transparent for the running applications on the mobile devices and satisfy wide range of services including voice, data, multimedia, and Web browsing.
