Abstract: A wireless local network and method integrating the locating and the seamless roaming of mobile nodes. The network includes a server constituting the core of the network, fixed access points providing the low-level protocol, fixed anchors providing the locating function and nodes comprising sensors and actuators according to the end purpose of the network. The fixed anchors determine a distance measurement with the nodes by time of flight of radio waves, with the nodes behaving as an active radio deflector.

Abstract: Wireless local network integrating the locating and the seamless roaming of mobile nodes. The device of the invention is comprised of a server (110) constituting the core of the network, fixed access points (120) providing the low-level protocol, fixed anchors (140) providing the locating function and nodes (140) comprising sensors and actuators according to the end purpose of the network. The regrouping of the upper network layers at the physical layer in the server allows for a seamless roaming and an approximate locating of the nodes by the network at each frame transmitted. The denser anchor network allows for a precise locating of the nodes, upon request, thanks to a distance measurement by time of flight of radio waves, with the nodes then behaving as an active radio deflector.
