- RF tag radiofrequency tag
- a source of radio waves for example, equipment transmitting radio waves for television, FM broadcasting waves (Frequency modulation), etc. . — emits radio waves in the environment in which it is located, i.e. ambient signals.
- An RF tag placed within range of the source can then receive an ambient signal (we say that it is "illuminated” by the source), and backscatters the ambient signal received; a radio wave reader located within transmission range of the RF tag will then be able to detect the ambient signal backscattered by the RF tag.
- Figure 1 shows a system according to the invention for detecting the presence of people carrying communicating devices, in a specific environment.
- the system (10) for detecting the presence of people comprises an ENV environment, for example a geographical area located in a closed room such as for example a restaurant, a museum, a business, or a geographic area bounded by an outer expanse such as a beach.
- ENV environment for example a geographical area located in a closed room such as for example a restaurant, a museum, a business, or a geographic area bounded by an outer expanse such as a beach.
- Figures 2, 3 and 4 described below illustrate examples of such environments.
- a set of RF tags configured to backscatter an ambient signal.
- FIG. 1 two RF tags, TG1 and TG2, are represented respectively fixed or more generally associated with material objects 01 and 02.
- these objects are tables distributed in the dining room of the restaurant, while in that of figures 3 and 4, corresponding to a private beach, the objects on which the labels are fixed RF are umbrellas or deckchairs spread over the beach.
- the system for detecting the presence of people comprises an AR network equipment, which, in the embodiment presented and illustrated, is, or is incorporated in, a relay antenna of a wireless communication network, for example a mobile telephone network of the 3G, 4G or 5G type (3rd, 4th or 5th generation).
- the AR network equipment is a Wi-Fi access point, also referred to as a Wi-Fi hotspot (Wi-Fi or wifi: set of wireless communication protocols governed by the standards of the IEEE 802.11 group), i.e. equipment that provides access to a Wi-Fi wireless network allowing users of mobile phones, touch pads or laptops to connect to the Internet.
- FIG. 1 Still in Figure 1, in the environment ENV are shown two communicating devices, T1 and T2, located respectively near the object 01 on which the label TG1 is fixed, and near the object 02 on which the TG2 label is attached.
- These two communicating devices are, in the disclosed embodiment of the invention, are mobile telephone terminals of the “smart telephone” type better known by the English term smartphone; these terminals can moreover be connected both to a Wi-Fi wireless network and to a mobile telephone network.
- Each of the communicating devices T1 and T2 is worn by a different person (not shown in the figure).
- Each of the communicating devices T1 and T2 (also referred to as “terminals” in the remainder of the description) transmit radio signals corresponding to the wireless communication network to which they are connected (4G or 5G telephone network, for example). to data or control signals conforming to a communication protocol corresponding to this network.
- radioelectric signal reference is made here to an electromagnetic wave propagating by non-wired means, the frequencies of which are included in the traditional spectrum of radioelectric waves (a few hertz to several hundred gigahertz).
- the radioelectric signals transmitted by the communicating devices T1 and T2 then constitute ambient signals, respectively S_AMB1 and S_AMB2, which, by way of example, are transmitted in the transmission band [811 MHz, 821 MHz] within the framework of the 4G mobile telephony.
- the labels TG1 and TG2 correspond respectively to the detection zones Z1 and Z2.
- the terminal T2 is located outside detection zones Z1 and Z2, consequently none of the tags TG1 and TG2 can detect the ambient signal S_AMB2 emitted by the terminal T2, and therefore none of the tags will backscatter the ambient signal emitted by T2.
- the terminal T 1 is located inside the detection zone Z1 of the tag TG1, the latter can then detect and receive the ambient signal S_AMB1 emitted by the terminal T1 , and consequently produce a backscattered signal S_R(1).
- an AR network equipment in this example an AR relay antenna connected to the wireless communication network to which the terminals T1 and T2 are connected, can receive signals backscattered by the tags TG1 and TG2, and in this example, only the backscattered signal S_R(1), and consequently obtain presence information comprising at least one item of identification data for the TG1 tag, a network identifier for the terminal T1, and the date of receipt of the signal backscattered S_R(1).
- This process will be detailed below in connection with Figure 5.
- the network equipment is connected by a wireless or wired network link to an Internet-type network NW.
- each of the user terminals T1 and T2 can connect, for example via a mobile telephone communication network, to the network NW.
- FIG. 1 is represented a server SVR which can be accessed by the network equipment AR. The role of the SVR server is described below.
- a test smartphone can be used beforehand to carry out a measurement campaign in order to determine the geographical area within which the tag is detected, via the signal that it backscatters.
- the detection zone of a considered RF tag can be controlled by ensuring that part of the ambient signal is focused on the tag and by increasing the level of illumination. of the label. More specifically, during a first learning phase, a receiver device (smartphone) learning device is positioned where the tag will be deployed, then the receiver device is used to cause the device emitting the ambient signal to focus the signal towards the receiver device.
- the learning receiver device is replaced by the RF tag which can then receive an ambient signal focused towards it.
- a learning smartphone can be positioned at a chosen limit detection distance (the detection zone on the ground of a tag is substantially a disc whose the label occupies the center) then depending on whether or not the backscattered signal is detected by the smartphone, the emission power of the ambient signal is gradually adapted by the transmitting device, until the smartphone detects the backscattered signal by the label.
- FIG. 2 represents a first example of an environment in which it is possible to implement a method for detecting the presence of at least one person wearing a communicating device.
- the environment is a restaurant comprising tables distributed in two rooms 21 (square 1) and 22 (square 2).
- a radiofrequency tag TG is arranged in the center of each of the tables and is associated with a detection zone Z_TG.
- the ambient signal could be broadcast for example by a Wi-Fi terminal associated with the restaurant.
- FIGs 3 and 4 illustrate a second example of an environment in which it is possible to implement a method for detecting the presence of at least one person wearing a communicating device.
- the environment is a private beach on which parasols for rent are each equipped with an RF tag configured to backscatter an ambient signal broadcast by a relay antenna of a 4G mobile telephone network.
- the beach is therefore divided into detection zones for the tags attached to the parasols.
- the umbrellas P31 and P33 are respectively associated with tags TG31 and TG33 (not shown) whose detection zone is respectively Z TG31 and Z TG33, while the umbrella P32 is associated with a TG32 tag (not shown) whose Z TG32 detection zone is much larger.
- Figure 4 illustrates another example of a private beach on which umbrellas (or deckchairs) are each equipped with an RF tag.
- some offer a reduced detection zone Z TG41 and Z TG42 making it possible to identify people equipped with communicating devices near the parasols on which the labels are affixed; other labels, on the contrary, offer a larger detection zone, such as Z TG43, making it possible to identify people entering or leaving the detection zone of the corresponding label.
- FIG. 5 we will now detail the main steps of a method for detecting the presence of at least one person carrying a device connected to a wireless communication network, in an environment determined.
- This environment can be by a closed and covered place such as a building or a delimited outdoor place, as illustrated by the examples described previously in relation to figures 2, 3 and 4.
- a communicating device In the environment considered (for example a restaurant), are present for a period of time and on a given date a set of users each of a communicating device, carried by the person (in a pocket for example) or located close to the person (for example placed on a table).
- a communicating device is a smartphone (also referred to as a user terminal below) connected to a mobile telephone network (4G for example).
- the geographical environment considered has a set of at least one radio frequency (RF) tag placed at a known or determined geographical position.
- RF radio frequency
- each of the tags is configured to backscatter ambient signals emitted by user terminals located respectively in the detection zone of the tag in question.
- the environment can be for example a closed place, such as a restaurant or a museum, but also an open space such as a football stadium comprising stands for the spectators, with rows of seats, some of which include an RF label. (for example one out of two seats per row of seats).
- each label is associated with label identification data making it possible to identify the label or the object on which it is attached or affixed.
- a list of labels is previously created and saved, for example in a server (SVR server in FIG. 1) connected to an Internet-type network or a private computer network (intranet); this list contains in particular an association between each tag identifier and geographical coordinates, for example GPS coordinates.
- the process for detecting the presence of people begins with a step S50 during which the communication terminal T1, carried by a person and located in the detection zone Z1 of the tag S_R(1), emits an ambient signal S_AMB1 on the wireless communication network to which the terminal T1 is connected (as well as the network equipment AR) .
- step S51 the tag TG1 receives the ambient signal S_AMB1 and backscatters it in the form of a signal S_R(1) which includes identification data (ID TG1) of the tag.
- the backscattered signal S_R(1) is then received by the network equipment AR, at step S52.
- a signal processing module (or software application AP-6, see FIG. 6), incorporated into the network equipment AR, analyzes the backscattered signal S_R(1) and extracts the identifier Tag TG1 ID. In addition, a first time datum DT1 representative of the instant of reception of the backscattered signal is also generated.
- the network equipment processing module recovers, from the backscattered signal, an identifier (I D T 1 ) of the communication terminal T1 transmitting the ambient signal S_AMB1.
- the processing module of the network equipment is configured to separate the signals coming from different terminals (by using a signal separation technique known from the state of the art). Then, once the frequency band of the backscattered signal received has been identified, the processing module consults a register in which associations between allocated frequency bands and network identifiers of corresponding terminals have been previously recorded.
- the ambient signal (S_AMB1) transmitted by the terminal T1 includes a message containing the network identifier (ID_T 1 ) of the terminal, and the backscattered signal S_R(1) retaining this message, the terminal network identifier can be directly extracted from the backscattered signal received by the network equipment.
- the processing module (AP-6) of the network equipment AR monitors the state of reception by the network equipment of the backscattered signal S_R(1). As long as the backscattered signal is received (S54 "yes)" monitoring continues.
- the application AP-6 of the network equipment AR generates, in step S55, a second time datum DT2 representative of the instant of end of reception of the backscattered signal, as well as a presence information Pres- Z1 (T1) of the terminal T1 in the geographical zone corresponding to the detection zone Z1 of the TG1 tag, this presence information being made up of the ID TG1 identifier of the tag, the aforementioned time data DT1 and DT2, as well than a network identifier of the terminal T1 (I D T
- step S56 the presence information Pres-Z1 (T1) is recorded in a database (or register) DB.
- the database DB is integrated into the presence information processing server SVR (database DB S), accessible via the network NW (see FIG. 1).
- the network equipment AR transmits the presence information obtained to the server SVR.
- the aforementioned database is distributed between the network equipment AR and the server SVR.
- a database DB_6 is integrated in the network equipment AR, and in which the application AP-6 of the network equipment records the presence information Pres-Zk(Tj) generated over time for backscattered signals received from a set of tags TGk of the environment, and whose corresponding ambient signal has been transmitted by any terminal Tj present in the environment. Then, the network equipment AR can periodically transmit to the server SVR the presence information Pres-Zk(Tj) generated during a period of time considered.
- the server SVR may, for example, then record in its local database DB S, and keep up to date, presence information received from a set of AR network equipment.
- the server SVR can, on request, analyze the presence information stored in the database DB S, and previously received in coming from one or more network equipment (AR), in order to identify (step S58) users present on a given date (or a given period of time) in a geographically determined place. People can be identified from the network identifier associated with their communication terminal whose emitted ambient signal has been detected by a radiofrequency tag in the place considered.
