The BlackBerry 8820 is the first dual-mode BlackBerry handset, combining EDGE/GPRS/GSM cellular and Wi-Fi connectivity for data access and voice support through UMA (unlicensed mobile access) for fixed-mobile convergence (FMC) service offerings from various wireless carriers around the world.

The BlackBerry 8820 smartphone supports the 802.11 a/b/g Wi-Fi standards to enable data access over Wi-Fi connections in the enterprise, as well as through public hotspots and wireless home networks. The BlackBerry 8820 also supports UMA, enabling wireless carriers to offer a fixed-mobile convergence service for both business and home use. With a UMA solution in place, the BlackBerry 8820 can also seamlessly switch voice calls between a wireless carrier’s cellular network and a Wi-Fi network.
