Description

 ADVERTISING PANEL WITH INTEGRATED MOBILE TELEPHONY RELAY

The present invention relates to an advertising panel with radio relay of integrated mobile telephony.

It relates generally to the industrial and commercial field of digital telecommunications networks allowing the use of portable telephones.

The radio telephone has long been reserved for few and localized professional users. The analog networks used entailed a high price for the terminals and a high cost of use due to the limited capacity of these networks. They were also perfectly incompatible between the different countries.

The European digital network "G. S.M." was commissioned in France in 1992 by the companies France Télécom and S.F.R. (French Broadcasting Corporation). It is a cellular-type digital network covering a growing part of European territory and gradually extending to countries outside the Community. It makes it possible to produce low-volume mobile terminals in the form of pocket telephone devices, which are more and more widespread.

The manufacturers have succeeded in imposing a new need, that of being reached and of being able to call everywhere. Of course, this need is paid for. First of all financially, then on a daily basis, due to the many problems faced by users.

The extremely rapid development of the mobile phone in recent years has caused network saturation leading to poor reception, especially in large cities. Faced with this explosion in the market, French operators are struggling to adapt to this clientele which has quadrupled in two years and to meet the technical challenge thus launched. According to the ART (Telecommunications Regulatory Authority) "The quality of service of French mobile telephone networks is generally good but has declined in the major French agglomerations". This poor reception in high density areas is mainly due to the overload of calls during peak hours, and the insufficient number of relays.

In fact, in large urban centers, the quantity of simultaneous communications requires a permanent increase in the number of radio relay stations. However, the available locations are becoming scarce and more and more expensive, when they are not lacking in certain areas.

The device according to the present invention aims to remedy this state of affairs in a large number of cases. It makes it possible to install radio relays in places where it is very difficult to find suitable locations.

It is made up of an advertising panel similar to those that one finds more and more frequently in the center of the cities and integrating the totality of the equipment of a hertzian relay for mobile phone and in particular an apparent antenna or not and a "radio bay" containing the equipment for connection to the energy supply network. The detailed description below relates to a non-limiting example of one of the embodiments of the subject of the invention.

In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention:

FIG. 1 shows an axonometric perspective of a double-sided advertising panel with central base and visible antenna,

FIG. 2 shows the same panel, seen from the front, with the antenna concealed in the structure of the panel,

Figure 3 shows under the same conditions a panel with one face and two support legs and Figure 4 is a side view of the same panel according to arrow F of the previous figure.

The device, FIGS. 1 to 4, consists of a single-sided 1 or double-sided advertising panel 2 fitted with a transmitter-receiver antenna 3 and an integrated radio bay 4.

The antenna 3 is of the type usually used for GSM relays installed for example on the roofs of buildings in built-up areas. It is generally in the form of an elongated rectangle arranged vertically grouping in fact receiving and transmitting antennas towards the mobile stations and possibly auxiliary antennas to ensure certain service or surveillance links. The antenna 3 can be mounted on a support mast 5 above the panel 1, 2 or, in certain cases, be hidden inside the panel, along one of its vertical sides.

The radio bay 4 is a cabinet grouping together all the electrical and electronic equipment necessary to ensure the necessary connections and conversions between the antenna 3 and the cable 6, most often underground, coming from a distributor of the GSM network A shielded cable 7 , placed inside the panel 1, 2 connects the radio bay 4 and the antenna 3.

According to a preferred embodiment, the advertising panel will be a double-sided panel 2 mounted on a single central leg 8 determined to be able to incorporate the radio bay 4. However, in the case of a single-sided panel 1, comprising for example two legs supports 9, this bay can be mounted in a box 10 integrated into the panel and mounted on the back of the latter.

The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
