Description

DISPOSITIF D'INTERCONNEXION À TRÈS COURTE PORTÉE ENTRE UN ÉQUIPEMENT DE COMMUNICATION ET UN RÉSEAU DE COMMUNICATION  VERY SHORT INTERCONNECTION DEVICE BETWEEN A COMMUNICATION EQUIPMENT AND A COMMUNICATION NETWORK
L'invention concerne les équipements de communication, et plus précisément l'interconnexion de tels équipements de communication à des réseaux de communication. The invention relates to communication equipment, and more specifically the interconnection of such communication equipment to communication networks.
Pour que l'on puisse connecter un équipement de communication à un réseau de communication, comme par exemple l'Internet ou un réseau local (ou LAN ("Local Area Network")), cet équipement de communication doit comporter un module de communication de type filaire ou non filaire (ou radio).  In order to connect a communication equipment to a communication network, such as the Internet or a Local Area Network (LAN), this communication equipment must include a communication module. wired or non-wired type (or radio).
Lorsque le module de communication est de type filaire, son couplage à un réseau de communication nécessite de le raccorder à un modem (ou tout périphérique équivalent) au moyen d'un câble de communication, puis de connecter ce modem à un connecteur dédié, éventuellement de type Ethernet, qui est connecté audit réseau de communication. Chaque établissement complet du couplage précité nécessite donc de nombreuses opérations manuelles, ce qui s'avère chronophage et rébarbatif. En outre, ce couplage s'avère réellement inesthétique dans la mesure où les câbles de connexion sont généralement apparents.  When the communication module is of wired type, its coupling to a communication network requires to connect it to a modem (or any equivalent device) by means of a communication cable, then to connect this modem to a dedicated connector, possibly Ethernet type, which is connected to said communication network. Each complete establishment of the aforementioned coupling therefore requires many manual operations, which is time-consuming and forbidding. In addition, this coupling is really unsightly insofar as the connection cables are generally apparent.
Lorsque le module de communication est de type non filaire (ou radio), son couplage à un réseau de communication non filaire (par exemple de type cellulaire ou WLAN ("Wireless LAN" - éventuellement de type 802.11 (ou WiFi) ou WiMAX)), se fait par voie d'ondes. Les points d'accès radio de ces réseaux de communication non filaires pouvant être relativement éloignés des équipements de communication qui s'y connectent, les ondes doivent être émises avec une puissance relativement importante afin d'avoir une portée suffisamment longue. Les personnes évoluent donc dans des environnements électromagnétiques qui sont plus ou moins denses. Or, il n'existe pas aujourd'hui de consensus relatif au danger que pourrait induire sur la santé, à court, moyen ou long terme, une exposition aux ondes électromagnétiques à longue portée qui sont utilisées pour échanger des données avec des réseaux de communication non filaires, compte tenu de leur puissance d'émission. Il en résulte qu'un nombre de plus en plus important de personnes refuse d'utiliser certains réseaux de communication non filaires (cellulaires ou WiFi) en raison d'un principe de précaution. Par ailleurs, l'interconnexion à un réseau de communication radio, notamment de type WiFi, pose de réels problèmes de sécurité, car elle peut permettre à un tiers malveillant de se connecter au réseau via la connexion d'une autre personne qui est située dans son voisinage immédiat. When the communication module is of the non-wired (or radio) type, its coupling to a non-wired communication network (for example of the cellular or WLAN type ("Wireless LAN" - possibly of type 802.11 (or WiFi) or WiMAX)) , is done by waves. Since the radio access points of these wireless communication networks can be relatively distant from the communication equipment that connects to them, the waves must be transmitted with a relatively high power in order to have a sufficiently long range. People therefore evolve in electromagnetic environments that are more or less dense. However, there is no consensus today on the danger that could in the short, medium or long term, exposure to long-range electromagnetic waves that are used to exchange data with non-wired communication networks, given their transmission power. As a result, more and more people are refusing to use certain wireless communication networks (cellular or WiFi) due to a precautionary principle. Furthermore, the interconnection to a radio communication network, including WiFi type, poses real security problems, because it can allow a malicious third party to connect to the network via the connection of another person who is located in its immediate neighborhood.
Aucune solution connue d'interconnexion à un réseau de communication n'apportant une entière satisfaction, l'invention a donc pour but d'améliorer la situation.  Since no known solution for interconnection to a communication network is entirely satisfactory, the purpose of the invention is therefore to improve the situation.
Elle propose à cet effet un dispositif, dédié à l'interconnexion entre un équipement de communication, muni d'un module de communication radio à très courte portée, et un réseau de communication, et comprenant:  It proposes for this purpose a device, dedicated to the interconnection between a communication equipment, provided with a very short-range radio communication module, and a communication network, and comprising:

[_'jnventiôn a pour objet d'offrir un dispositif d'interconnexion (D) d'u n nouveau genre, permettant une interconnexion entre un équipement de communication (EC) et un réseau de communication (RC), susceptible d'induire un minimum de risque pour la santé des personnes, et/ou d'empêcher des tiers malveillants de se connecter via les connexions d'autres personnes situées dans leur voisinage immédiat. The purpose of the invention is to provide a new type of interconnection device (D), allowing interconnection between a communication equipment (CE) and a communication network (RC), capable of Minimize the risk to people's health, and / or prevent malicious third parties from connecting through the connections of others in their immediate vicinity.
On a schématiquement illustré sur les figures 1 et 2, un exemple non limitatif de dispositif d'interconnexion D selon l'invention, destiné à assurer l'interconnexion entre un équipement de communication EC, équipé au moins d'un module de communication radio MCR à très courte portée (typiquement inférieure à 20 cm), et un réseau de communication RC lorsque sont réunies certaines conditions, sur lesquelles on reviendra plus loin.  FIGS. 1 and 2 diagrammatically illustrate a nonlimiting example of an interconnection device D according to the invention intended to ensure the interconnection between a communication equipment item EC, equipped at least with an MCR radio communication module. very short range (typically less than 20 cm), and an RC communication network when certain conditions are met, which will be discussed later.
Dans les exemples non limitatifs illustrés sur les figures 1 à 3, l'équipement de communication EC est un ordinateur portable (ou "laptop"). Mais, l'invention n'est pas limitée à ce type d'équipement de communication. Elle concerne en effet tout type d'équipement de communication filaire et/ou non filaire (ou radio), capable d'échanger des données avec un autre équipement de communication ou équipement de réseau, via un réseau de communication. Par conséquent, il pourra par exemple s'agir d'un téléphone fixe ou mobile (ou cellulaire), éventuellement de type "smartphone", d'un ordinateur fixe ou portable, d'un assistant personnel numérique (ou PDA), d'un récepteur de contenus multimédia (par exemple un décodeur, une passerelle résidentielle (ou « residential gateway ») ou un STB (« Set-Top Box »)), dès lors qu'il est équipé d'au moins un module de communication bidirectionnelle radio MCR à très courte portée. In the non-limiting examples illustrated in Figures 1 to 3, the communication equipment EC is a laptop (or "laptop"). But, the invention is not limited to this type of communication equipment. It concerns any type of wired communication equipment and / or non-wired (or radio), capable of exchanging data with other communication equipment or network equipment, via a communication network. Therefore, it may for example be a fixed or mobile phone (or cellular phone), possibly of the "smartphone" type, of a fixed or portable computer, of a personal digital assistant (or PDA), of a receiver of multimedia contents (for example a decoder, a residential gateway (or "residential gateway") or a STB ("Set-Top Box")), since it is equipped with at least one bidirectional communication module MCR radio with very short range.
Dans ce qui suit, on considère à titre d'exemple non limitatif que le module de communication radio MCR est de type WiFi à très courte portée (ou WiFi-SD ("Short Distance")). Mais, l'invention n'est pas limitée à ce type de standard de communication radio. Elle concerne en effet tout type de standard de communication radio à courte portée (et donc nécessitant une faible, voire très faible, puissance d'émission), et notamment le standard Bluetooth. On notera que le module de communication radio MCR peut être implanté à l'intérieur d'un équipement de communication EC, ou bien peut être un accessoire (éventuellement de type "dongle") que l'on vient accoupler à un connecteur (éventuellement de type USB) d'un équipement de communication EC, quand on veut utiliser le dispositif D selon l'invention.  In the following, we consider as a non-limiting example that the MCR radio communication module is very short-range WiFi type (or WiFi-SD ("Short Distance")). However, the invention is not limited to this type of radio communication standard. It concerns indeed any type of short-range radio communication standard (and therefore requiring a low or very low transmission power), and in particular the Bluetooth standard. It will be noted that the radio communication module MCR can be implanted inside a communication equipment EC, or it can be an accessory (possibly of the "dongle" type) that is coupled to a connector (possibly of USB type) of an EC communication equipment, when it is desired to use the device D according to the invention.
Comme illustré sur les figures 1 à 3, un dispositif (d'interconnexion) D, selon l'invention, comprend au moins des moyens de relais MR et une antenne AN.  As illustrated in FIGS. 1 to 3, an (interconnect) device D according to the invention comprises at least one of relay means MR and an antenna AN.
Les moyens de relais MR sont agencés (ou conçus) pour relayer des données, qu'ils ont reçues sous forme de signaux, soit vers des moyens de couplage MCP qui sont couplés au réseau de communication RC (directement ou indirectement), du fait qu'elles sont issues d'un équipement de communication EC qui interagit avec leur dispositif D (comme illustré sur les figures 2 et 3), soit vers l'antenne AN du fait qu'elles sont issues des moyens de couplage MCP et destinées à l'équipement de communication EC (lorsqu'il interagit avec le dispositif D).  The relay means MR are arranged (or designed) to relay data, which they have received in the form of signals, or to MCP coupling means which are coupled to the communication network RC (directly or indirectly), because they come from a communication equipment EC which interacts with their device D (as illustrated in FIGS. 2 and 3), or towards the antenna AN because they originate from the coupling means MCP and are intended for the EC communication equipment (when interacting with the device D).
Ces moyens de relais MR définissent donc, en quelque sorte, un élément de connectivité assurant l'interface de relais entre une antenne AN et des moyens de couplage MCP. These relay means MR thus define, in a way, a connectivity element providing the relay interface between an antenna AN and MCP coupling means.
L'antenne AN est couplée au moins électriquement aux moyens de relais MR (par exemple ils sont en contact étroit). Cette antenne AN est propre à rayonner et capter des ondes électromagnétiques à très courte portée qui sont représentatives de données échangées. Pour ce faire, elle peut être de n'importe quel type dès lors qu'elle présente une très faible extension verticale. Ainsi, elle pourra être de type dit à pavé (ou "patch") ou à fente(s) (ou "slot") ou à dipôle, et plus généralement de type dit panneau (ou plate). On notera que le lieu du contact entre l'antenne AN et les moyens de relais MR dépend du type de l'antenne AN.  The antenna AN is coupled at least electrically to the relay means MR (for example they are in close contact). This antenna AN is able to radiate and capture very short-range electromagnetic waves that are representative of exchanged data. To do this, it can be of any type since it has a very small vertical extension. Thus, it may be of type called pad (or "patch") or slot (s) (or "slot") or dipole, and more generally of said type (or flat). It will be noted that the place of contact between the antenna AN and the relay means MR depends on the type of antenna AN.
Le rayonnement est destiné à transmettre par voie d'ondes à très courte portée, au module de communication radio MCR de l'équipement de communication EC, des données qui ont été fournies par les moyens de relais MR (sous forme de signaux électriques) et donc qui sont issues d'un réseau de communication RC. Dans ce cas, l'antenne AN convertit les signaux électriques reçus en ondes électromagnétiques (qu'elle émet).  The radiation is intended to transmit, by very short-range waves, to the radio communication module MCR of the communication equipment EC, data that has been supplied by the relay means MR (in the form of electrical signals) and therefore that come from an RC communication network. In this case, the antenna AN converts the received electrical signals into electromagnetic waves (which it emits).
La capture est destinée à réceptionner des données transmises par — voie d'ondes à très courte portée par te module de communication radio MCR de l'équipement de communication EC, afin de les communiquer (sous forme de signaux électriques) aux moyens de relais MR pour qu'ils les communiquent aux moyens de couplage MCP du fait qu'ils sont destinés au réseau de communication RC auquel ils sont connectés. Dans ce cas, l'antenne AN convertit les ondes électromagnétiques (qu'elle reçoit) en signaux électriques.  The capture is intended to receive data transmitted by very short-range radio waves by the radio communication module MCR of the communication equipment EC, in order to communicate them (in the form of electrical signals) to the relay means MR. to communicate with the MCP coupling means because they are intended for the RC communication network to which they are connected. In this case, the antenna AN converts the electromagnetic waves (which it receives) into electrical signals.
On comprendra que l'échange de données par voie d'ondes à très courte portée ne peut se faire qu'à condition que l'équipement de communication EC soit placé dans le voisinage immédiat de l'antenne AN, comme illustré sur les figures 2 et 3. On notera que dans l'exemple de la figure 1 , l'interaction entre l'équipement de communication EC et le dispositif D ne peut pas se faire du fait que l'équipement de communication EC est trop éloigné de l'antenne AN.  It will be understood that the very short-wave data exchange can be done only if the communication equipment EC is placed in the immediate vicinity of the antenna AN, as illustrated in FIGS. and 3. Note that in the example of Figure 1, the interaction between the communication equipment EC and the device D can not be done because the communication equipment EC is too far from the antenna YEAR.
Tous les types de moyens de relais MR connus de l'homme de l'art peuvent être utilisés. Ainsi, on peut utiliser des moyens de relais MR qui sont agencés pour échanger des données par voie d'ondes avec les moyens de couplage MCP, comme illustré non limitativement sur les figures 1 et 2. Ces ondes peuvent être de n'importe quel type dès lors qu'elles sont de faible puissance et de portée limitée, et donc (quasiment) sans danger pour la santé. Ainsi, elles peuvent être de type infrarouge (ou IR). Dans ce cas, et comme illustré non limitativement sur les figures 1 et 2, les moyens de couplage MCP peuvent être agencés sous la forme d'un équipement émetteur/récepteur infrarouge qui est du type dit "à courant porteur en ligne" et connecté directement à une prise de courant électrique PC (éventuellement murale). Cette prise de courant électrique PC est reliée à un réseau électrique qui est couplé à un réseau de communication RC de type filaire. All types of MR relay means known to those skilled in the art can be used. Thus, it is possible to use relay means MR which are arranged to exchange data by waves with the MCP coupling means, as shown in non-limiting manner in FIGS. 1 and 2. These waves can be of any type provided they are of low power and reach limited, and therefore (almost) safe for health. Thus, they can be of the infrared (or IR) type. In this case, and as illustrated in non-limiting manner in FIGS. 1 and 2, the MCP coupling means can be arranged in the form of an infrared transmitter / receiver equipment which is of the type called "in-line carrier current" and connected directly to a PC electrical outlet (possibly wall mounted). This PC electrical outlet is connected to an electrical network which is coupled to a wired type RC communication network.
En variante, on peut utiliser des moyens de relais MR qui sont agencés pour échanger des données par voie filaire avec les moyens de couplage MCP, comme illustré non limitativement sur la figure 3. Dans ce second exemple (filaire), les moyens de relais MR sont connectés aux moyens de couplage MCP au moyen d'un câble de communication CC. Ce dernier (CC) peut, comme illustré non limitativement, être intégré dans l'équipement de support T qui est équipé du dispositif D et sur lequel est posé l'équipement de communication EC. Par exemple, les moyens de couplage MCP peuvent être agencés sous la forme d'un modem (ou de tout équipement équivalent) qui est connecté au moyen d'un autre câble de communication à une prise de communication PT (éventuellement murale), par exemple de type Ethernet. Cette prise de communication PT peut être connectée à un réseau de communication RC de type filaire par un câble téléphonique (xDSL) ou par des fibres optiques.  As a variant, it is possible to use relay means MR which are arranged to exchange data by wire with the MCP coupling means, as shown in non-limiting manner in FIG. 3. In this second example (wired), the relay means MR are connected to the MCP coupling means by means of a communication cable CC. The latter (CC) may, as illustrated without limitation, be integrated in the support equipment T which is equipped with the device D and on which the communication equipment EC is placed. For example, the MCP coupling means can be arranged in the form of a modem (or any equivalent equipment) which is connected by means of another communication cable to a PT (possibly wall-mounted) communication socket, for example Ethernet type. This PT communication socket can be connected to a wired RC communication network by a telephone cable (xDSL) or by optical fibers.
On notera que dans une variante les moyens de couplage MCP peuvent être une simple prise de communication (éventuellement murale), et non pas un modem.  Note that in a variant the MCP coupling means may be a simple communication socket (possibly wall), not a modem.
On notera également que les moyens de couplage MCP peuvent éventuellement faire partie du dispositif D, quel que soit leur type.  It will also be noted that the MCP coupling means may possibly be part of the device D, whatever their type.
On notera également, comme illustré non limitativement sur les figures 1 à 3, que l'antenne AN et les moyens de relais MR peuvent être avantageusement solidarisés à un support SP qui fait alors partie du dispositif D et dont les dimensions sont au moins égales à celles de l'antenne AN (afin de bien la supporter et éventuellement de la protéger). Un tel support SP peut être de type rigide ou flexible. Ainsi, il peut, par exemple, être agencé sous la forme d'une couche (ou d'une structure multicouches) définissant un tapis de relativement grandes dimensions. It will also be noted, as illustrated without limitation in FIGS. 1 to 3, that the antenna AN and the relay means MR may advantageously be secured to a support SP which is then part of the device D and whose dimensions are at least equal to those of the antenna AN (in order to support it well and possibly to protect it). Such a support SP can be of rigid or flexible type. Thus, it may, for example, be arranged in the form of a layer (or a multilayer structure) defining a carpet of relatively large dimensions.
Par exemple, on peut commencer par solidariser les moyens de relais MR au support SP, puis on peut solidariser l'antenne au support SP, par dessus les moyens de relais MR, et on peut éventuellement placer au dessus de l'antenne AN un film protecteur ou une couche protectrice transparente aux ondes électromagnétiques à très courte portée.  For example, it is possible to start by joining the relay means MR to the support SP, then the antenna can be secured to the support SP, over the relay means MR, and a film can be placed above the antenna AN. protector or protective layer transparent to electromagnetic waves at very short range.
Ce support SP peut être solidarisé fixement à une face inférieure d'un équipement de support T qui est propre à recevoir un équipement de communication EC. Cette solution est particulièrement bien adaptée aux équipements de support T qui sont implantés dans les bureaux, et notamment à ceux qui constituent des tables ou bureaux informatiques.  This support SP can be fixedly secured to a lower face of a support equipment T which is adapted to receive an EC communication equipment. This solution is particularly well suited to the support equipment T which is located in offices, including those that are tables or computer offices.
On entend ici par "face inférieure", la face qui est opposée à la face supérieure destinée à supporter des objets.  Here, the term "bottom face", the face which is opposite to the upper face for supporting objects.
Oans une vanante, le dispositif D peut être un accessoire portable, ët donc que l'on peut transporter avec soi afin de pouvoir l'utiliser dans de nombreux endroits, sous réserve que ces derniers soient situés à proximité immédiate d'une prise de courant électrique PC. Dans ce cas, le support SP est agencé de manière à pouvoir être posé sur la face supérieure d'un équipement de support T (quel qu'en soit le type dès lors qu'il peut recevoir un équipement de communication EC). C'est notamment le cas dans les exemples non limitatifs illustrés sur les figures 1 à 3. On notera que pour faciliter le transport du dispositif D son support SP et son antenne AN peuvent être flexibles. O a vanante, the device D can be a portable accessory, so it can be carried with you for use in many places, provided that they are located in the immediate vicinity of an outlet. PC electric current. In this case, the support SP is arranged so as to be placed on the upper face of a support equipment T (whatever the type since it can receive an EC communication equipment). This is particularly the case in the non-limiting examples illustrated in Figures 1 to 3. Note that to facilitate the transport of the device D support SP and antenna AN can be flexible.
