Net3

Net3 was a Wi-Fi-like system developed, manufactured and commercialised by Olivetti in the early 1990s. It could wirelessly connect PCs to an Ethernet fixed LAN at a speed of up to 512 kbit/s, over a very wide area. It was a micro-cellular system, in which each base station had an effective range of about 100m indoors, 300m outdoors, and the system supported seamless handover between base stations.
