| titleOfInvention | Wireless coupling of devices to a cable network. |
| abstract | Communication controllers (C1, C2, C3, C4) spaced from each other and coupled to a network of cables maintain communication between a portable device (18) and the network to allow data transmission. Each controller (C1, C2, C3 or C4) communicates with the portable device (18) via broadcast data packets, and requires the registration of the portable device (18) before offering packet transmission services. . The registration process consists in transmitting a packet from the portable unit (18) by requesting a response from the controllers (C1, C2, C3, C4) in transmitting a response packet from each controller ( C1, C2, C3, C4) receiving the request, selecting one of the responding controllers (C1, C2, C3, C4) at the portable unit (18) and according to criteria improving the transmission of data, and transmitting from said portable unit (18) a packet indicating the selected controller, which completes registration. The selected controller transmits to the other controllers via the network cable (10) a packet validating the registration. The controller with which the portable unit (18) was previously registered responds by canceling the registration of the unit (18) and transmitting via the cable (10) to the newly selected controller any stored packets including unit (18) is the recipient. The portable unit (18) operates on batteries, and an energy saving procedure consisting in deactivating the packet receiving section of the unit (18) is continuously adjusted to adapt to the speed of the transmissions. intended for the unit (18). |
