Heeding a call from Secretary-General Kofi Annan to extend Internet connectivity to underserved populations around the world, the United Nations Information and Communication Technologies (ICT) Task Force and the Wireless Internet Institute has announced a series of programmes to accelerate the adoption of wireless Internet in support of universal connectivity. In his challenge to Silicon Valley in 2002, the Secretary-General said: "We need to think of ways to bring wireless-fidelity applications to the developing world so as to make use of unlicensed radio spectrum to deliver cheap and fast Internet access."
