Lifi Mesh Networks
LiFi is a wireless networking technology that uses light, instead of radio waves, to pass data between computers. Mesh Networks that use LiFi instead of (or as well as) WiFi have the potential to work much more reliably, use less energy, and cause less EMF pollution. At present, LiFi has mostly been tested over very short distances, like within the rooms of a building. But in theory, LiFi transceivers on the top of buildings could be used to network with neighbouring buildings, creating a WAN (Wide Area Network) or MAN (Metropolitan Area Network). If the light used for LiFi networking can be successfully transmitted and received over longer distances, it could be used to connect towns and cities to each other. Danyl Strype
