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.

Claim (Index 6):
Network according to  claim 1 , comprising several nodes (N,  130 ) and at least two access points (PA,  120 ), said network further comprising at least one of the following characteristics:\n the access points (PA,  120 ) are connected to the server (S,  110 ) by TCP/IP computer links of which the latencies are less than 300 milliseconds, the nodes (N,  130 ), the anchors (A,  140 ) and the access points (PA,  120 ) are provided with radio transmitters-receivers that operate with the same modulation and in the same frequency band, the radio coverage areas of the access points (PA,  120 ) overlap at least partially, the access points (PA,  120 ) act on the layer 1 of the network and are transparent for the layer 2 of said network, in such a way that the communication between the nodes (N,  130 ) and the server (S,  110 ) as well as the communication between the anchor (A,  140 ) and the server (S,  110 ), is carried out transparently, without needing to address, or to be associated explicitly with one or more access points (PA,  120 ), data is exchanged in both directions between the nodes (N,  130 ) and the server (S,  110 ), the nodes (N,  130 ) communicate with the access points (PA,  120 ) thanks to an asynchronous level 2 protocol, wherein all of the exchanges are initiated by a node and wherein the server (S,  110 ) has a delay that is greater than double the typical latency between server and access points for transmitting a response to a node (N,  130 ) by the intermediary of an access point (PA,  120 ), the server ( 5 ,  110 ) is suitable for identifying frames received simultaneously by several access points (PA,  120 ), and for selecting, from those having received a frame transmitted by a node (N,  130 ), a single access point through which a response frame can be sent, the server ( 5 ,  110 ) is suitable for sending a frame containing commands to each anchor (A,  140 ) at any time, by the intermediary of an access point (PA,  120 ) known a priori, the server ( 5 ,  110 ) is suitable for using multiple distance measurements with a target node (N,  130 ), carried out by more than three anchors (A,  140 ) of which the positions are known, in order to calculate the position of said target node.
