At Mobile World Congress today, Cisco is introducing the industry's first carrier-grade, end-to-end Wi-Fi infrastructure to deliver Next-Generation Hotspots (NGH). The company also announced that it is working with several leading global service providers, including AT&T, BT, PCCW mobile, Portugal Telecom, Shaw Communications, Smart and True, to deliver mobile services with a new generation of intelligent 'small cell' solutions utilizing licensed and unlicensed radio technology. Cisco, which is now embedding Wireless Broadband Alliance (WBA)-approved NGH technology within its service provider Wi-Fi portfolio, recently became the first to deploy NGH technology to enable cellular-like roaming for Wi-Fi networks.
