摘要

results: Researchers in India have de-veloped 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.
