American Wireless local area networking (WLAN) manufacturer Trapeze Networks has upgraded its Mobility System Software to enable a new model of wireless deployment. Using virtual service sets, networks built with Trapeze equipment can deliver public and private WLAN services anywhere, over a single infrastructure to different constituencies while securing and isolating each group’s traffic and controlling where they roam and the resources they use. Trapeze Web Services for Wireless, another new feature set, is a complete package of browser based services for authenticating users and precisely regulating their access to network resources, accounting for network usage, and offering advertising and promotional services. Trapeze is also delivering a guest provisioning application that makes it simple to enable visitor access to a wireless network. These new capabilities are targeted at mixed-use environments including: transportation hubs such as airports and rail stations, shopping malls, colleges and universities, and multi-tenant commercial and residential properties. Virtual service sets allow a wireless network to be virtualised so disparate services can coexist on the same wireless infrastructure. Each component that comprises a service is configured separately: “We have found Trapeze’s Virtual Service Sets to be a very useful tool in our network,” says Chris Hessing, Head of Networking at the J. Willard Marriott Library at the University of Utah. “One way we use them is to provide the 802.1X client plug-ins that our users need. In certain areas of the building we broadcast both a secure and insecure network. The insecure network is restricted to getting information and software to connect to the secure network. This helps us eliminate the chicken and the egg problem of providing 802.1X software over the network, but requiring 802.1X to get it,” he adds.
