Long-Distance Wi-Fi
Protocol extends the range of wireless networks
Results: Researchers in India have developed a communications protocol to increase the coverage area of Wi-Fi mesh networks. In a conventional Wi-Fi network -- like the ones that are now common at many urban cafEs and airports -- a base station with a wired connection to the Internet exchanges radio signals with users' portable devices.
In a Wi-Fi mesh network, by contrast, several nodes can exchange radio signals with each other as well as with users. Such a network can provide Wi-Fi coverage for a given geographical area at a lower cost than a series of conventional Wi-Fi networks, because not all of its nodes must be wired to the Internet.
