Roaming

Roaming in a WiFi WLAN is the ability to move seamlessly from one RF cell or coverage area to another without losing higher layer network connectivity. Roaming in 802.11 wireless networks is not straightforward. For seamless roaming in multi-vendor networks, an Inter-Access Point Protocol (IAPP) is required, and there is no standard available at present. Where layer 2 encryption gateways or layer 3 VPNs are used, data can be lost during handover between access points. Finally, roaming between 802.11 hotspots and mobile networks, such as GPRS and UMTS, is an area where only proprietary software solutions exist at present.
