Security, Mobility and QoS in Open Access: Can you Get Three Things at Once?

The broadband access capacity that connects homes to the Internet is often only partially consumed, either because of the relatively low-range access subscription selected or because the user is not constantly on-line. By allowing strangers - that happen to be near but outside the home - to make use of these residential access facilities through their WLAN equipped terminals, the usage of the network capacity can be increased substantially. The challenge is to offer this access service in such a way that it is comparable to the services offered in 2G/3G networks, including the support of quality of service, secure connections and the possibility to roam from one home to another while continuing the session without noticeable disruptions. This paper sketches how to realise these challenges in an integrated solution.
