Wi-Fi is increasingly emerging as a feature on smartphones and tablets, but today there is no consistency in the way these devices attach to Wi-Fi networks. This process includes device configuration, the use of access keys and the various mechanisms for acquiring and paying for connectivity. Wi-Fi roaming will allow mobile devices to seamlessly connect to a Wi-Fi hotspot using the SIM card for authentication, as well as enable mobile operators to uniquely and securely identify users whether they are on a mobile or Wi-Fi network.
Wi-Fi roaming will be based on the WBA's 'Next Generation Hotspot' programme and the Wi-Fi Alliance's 'Passpoint certification' technology. It will also build on the GSMA's successful roaming principles that have propelled the mobile industry to more than six billion mobile connections worldwide, a number that is expected to more than double within the next ten years.
To date, the Wi-Fi roaming initiative has identified and agreed to the basis for a common approach to authenticating mobile devices on Wi-Fi hotspots, automatically and securely. It will now work towards aligning guidelines on security, billing, data offload, device implementation and network selection to create a consistent solution for GSMA and WBA members. This work will build on the GSMA's GPRS Roaming Exchange (GRX) and the WBA's Wireless Roaming Intermediary Exchange (WRIX) roaming models, which combined, will enable billions of consumers around the world to enjoy straightforward Internet connectivity.
