London Ambulance Service is the largest ambulance service in the world, caring for more than one and a half million patients every year. A solution was needed that would enable London Ambulance to simultaneously switch between multiple wireless wide area (WWAN) and wireless local area (WLAN) network connections. Seamless Network Switching, a key component of the Broadbeam ExpressQ Wireless Platform, provided automatic switching between multiple wireless wide area (WWAN) and wireless local area (WLAN) network connections. Now, when a London Ambulance vehicle leaves the 802.11b WLAN environment, its connection can seamlessly switch to the GPRS (general packet radio service) and GSM (global system for mobile communication) networks as they become available for seamless communication.
