Description

FIELD OF THE INVENTION The invention relates to a LAN cable and a LAN installation incorporating such a cable.

STATE OF THE ART In order to provide multiple services combining voice, video and multimedia services, local communication networks must have ever more important data transmission capabilities. The increase of the transmission capacities passes by the increase of the carrier frequencies used for the wireless data transmission (via the WiFi protocol for example). The WiFi protocol makes it possible to transmit wireless data between a connection point (such as for example a fixed subscriber terminal called a "box") connected to a communication network and a user terminal (such as for example a computer or any other communicating object). The 802.11 WiFi standards allow a data to be broadcast in a building on 2.4 GigaHertz radio frequency bands and have a fairly large range, which can vary from 10 to 100 meters approximately. However, the transmission rates are less than 54 Megabits per second (ie a real data rate of 27 Megabits per second). The WiFiG or 802.11ad standard makes it possible to broadcast data in the building with higher transmission rates of more than 1 Gigabits per second. However, the signals exchanged on the 60 GigaHertz radio frequency band do not generally cross the walls, the possible metal structures and other furniture. In addition, the range is reduced to about 5 to 8 meters in free space. Local network installations are known that use "radio-over-fiber" transmission techniques (Radio-Over-Fiber) to defer radio frequency transmission and reception of data in the different rooms of the building by using of optical fibers. These installations generally comprise a set of optical fibers connected to the connection point and connected to antennas arranged in the different rooms.

However, some devices are not equipped with radio-frequency transceivers adapted to communicate wirelessly with the antennas of these installations. In addition, some services are not accessible through WiFi. This is the case, for example, of wired telephone, digital terrestrial television (DTT) or satellite television. SUMMARY OF THE INVENTION An object of the invention is to propose an installation allowing simultaneous access to a large number of services. According to a first aspect, this object is achieved within the framework of the present invention by means of a local network installation, comprising: an optical or coaxial coupler, a plurality of transceiver modules intended to be distributed in different locations in a building, 20 - a plurality of cables, each cable comprising a first conductive assembly comprising at least two metal conductors, a second conductive assembly, and a sheath surrounding the first conductive assembly and the second conductive assembly, the sheath comprising two sheath elements longitudinally separable so as to allow independent connection of the first conductive assembly and the second conductive assembly, each cable connecting the optical or coaxial coupler to one of the transceiver modules via the second conductive assembly of the cable, each transmitter-receiver module; receiver being adapted to transmit according to a com protocol wireless communication to user terminals present in the building, data signals transmitted by the second driver assembly, and transmit by the second driver assembly data signals received from the user terminals according to a wireless communication protocol. By "local network" is meant a residential network or a tertiary network, that is to say a network that connects a set of terminals of the same building or a small group of buildings. The cable implemented in the proposed installation makes it possible to transmit in the same channel the radio-over-fiber (or radio-over-coaxial) data signals or any other service using the optical fiber (or coaxial) and telephone, Ethernet or television signals via the pair (s) of metal conductors, without generating additional installation costs. In other words, the invention makes it possible to take advantage of local cabling allowing the transmission of radio data over fiber (or over coaxial) or any other service using fiber (or coaxial), to also authorize access to services which can not be transmitted via optical fiber (or coaxial), in particular terrestrial television or satellite television.

On the other hand, the first conductive assembly may comprise a shielding shell surrounding the metal conductors. The two metallic conductors surrounded by the shielding envelope preferably exhibit a substantially constant attenuation in the frequency bands used for the broadcasting of digital or analogue television. For example, for the broadcasting of analogue television in France, it is the frequency band III between 174 and 230 MegaHertz. For the broadcasting of digital terrestrial television in France, these are the frequency bands IV and V, between 470 and 862 MegaHertz. A "substantially constant" attenuation means that the attenuation of the power of the signals transmitted by the two metallic conductors is devoid of peaks for the frequencies considered.
