Economist.com: “Here are four emerging technologies that show much promise: smart antennas, mesh networks, ad hoc architectures, and ultra-wideband transmission. Smart antennas are already in use and mesh networks are starting to appear, while ad hoc architectures and ultra-wideband are still largely restricted to the laboratory. But each challenges existing ways of doing things; each, on its own, or in combination with others, could shake up the wireless world.”
This is very important for emerging markets because they need hihg-speed communications right down to the last mile, without the costs and time for lating fibre, etc. Wireless is a possible answer for them to leapfrog.
