The disclosure relates to a mobile device detection and location system for passenger cabins of a vehicle, which enables a vehicle infotainment system to monitor radio frequency emissions and identify locations of mobile devices located within the cabin.
Vehicle manufacturers have developed various types of in-vehicle and/or on-board computer processing systems that include vehicle control, mobile and nomadic device communications systems, related messaging and control capabilities, and various other vehicle related applications. Additionally, such vehicle systems sometimes are further configured to enable automated vehicle features, and secure pairing and communications with such mobile and nomadic devices when located inside the vehicle. One such automated capability includes, for example, detecting a mobile or nomadic device that is configured to operate as a key and/or key fob for the vehicle, when such a key or key fob is detected to be within an effective range of a driver seat position.
Such key-fob-enabled mobile and/or nomadic devices have typically been configured as Bluetooth low energy (BLE) devices that must be within a predetermined range of a transceiver in the vehicle to enable such operations. While some advances have been made to detect locations of such mobile and nomadic devices within a cabin of the vehicle, limitations persist that prevent consistent and accurate location detection capabilities, and opportunities for improvements persist.
Many types of personal, commercial, and industrial vehicles, including combustion engine and hybrid, plug-in hybrid, and battery electric vehicles, hereafter collectively referred to as “vehicles,” include several types of in-vehicle computing systems, controllers, interfaces, networks, communications capabilities, and related applications. Such onboard systems and applications enable vehicle operation, as well as vehicle to mobile and nomadic device communications, and related capabilities that enable detection of such mobile and nomadic devices at precise locations inside the vehicle cabin.
The disclosure is directed to a vehicle that includes at least one and/or one or more in-vehicle and/or onboard controller(s) that is/are coupled to sensor groups spaced apart and arrayed within a cabin of the vehicle. Each sensor group generally corresponds to and/or with a plurality of and/or one or more seat positions that each have respective cabin seats, including a driver zone seat position that has a driver seat.
Each sensor group in the array includes at least one signal and/or digital signal processor (hereafter referred to as DSP or DSPs), and a plurality of antennas configured for and tuned to different electromagnetic frequencies. Each of the respective antennas also include and/or incorporate electromagnetically active, directional waveguides that adjust, amplify, and/or attenuate the sensitivity of each of the respective antennas and their responsiveness to electromagnetic energy received from and emitted by mobile or nomadic devices within the cabin and within a substantially limited effective range (LER) of each antenna.
The directional waveguide(s) may be formed from reflective, absorptive, and combination materials that are configured to adjust the sensitivity and electromagnetic responsiveness of the antennas. Each sensor group includes at least one of such waveguides and may also include one waveguide for each antenna of the sensor group, configured to adjust the capabilities for each antenna of the sensor group. In further variations, each sensor group also includes one or more of such waveguides to correspond to and/or be integrated with each and/or one or more of the antennas of the sensor group. Such waveguides may utilize materials formed and/or configured as band pass filters, polarizers, electromagnetic energy shields, masks, and/or other constructions that limit, adjust, attenuate, augment, and/or amplify antenna sensitivity, impedance, reception power, and/or responsiveness to electromagnetic frequencies and powers emitted by the contemplated mobile and nomadic devices when located inside the cabin.
Each of such configurations adjust the antennas such that mobile and nomadic device electromagnetic emissions may be detected and received by the antennas from within the respective LER of each antenna, and wherein the LER is adjusted by the waveguide(s) to correspond to and/or be super-positioned proximate to respective, single seats and/or seat positions. In these arrangements, the controller(s) are further configured to detect a location and/or seat position and one or more connection status(es) of the one or more nomadic and/or mobile devices located in the cabin, and to generate at least one and/or one or more mobile device and/or vehicle commands responsive to and according to the seat position and/or connection status(es).
The sensor groups and/or antennas of the groups are, in some variations of these arrangements, integrated into a headliner of the cabin, with each sensor group positioned to correspond with a respective seat position and seat proximate the position. At least one waveguide or each sensor group and/or each respective antenna is configured to establish the LER to be substantially limited to each respective seat position for each antenna of each sensor group and/or each sensor group.
In this configuration, the controller(s) alone, and/or in combination with one or more of the signal processor and each sensor group, is/are configured to generate locations, according to the limited effective range of the antennas, of each of the one or more mobile devices, which locations identify, are relative to, and/or are associated to each and/or one specific seat and/or seat position. Such seats and seat positions include the driver zone and the driver seat. In further modifications, the sensor groups and/or antennas thereof are positioned proximate to a seat position in the cabin, and also may be included, integrated, and/or incorporated as part of each seat within each seat position. In this arrangement too, the controller(s), alone and/or in combination with the DSP(s), generates the location of each mobile and/or nomadic device, relative to each proximate seat position and/or integrated seat.
In modifications to such variations, each sensor group includes the at least one and/or or one or more waveguide(s) being configured to establish the LER to be substantially limited to each respective seat position and/or seat for each antenna of each sensor group. As with other adaptations, the controller(s), in combination with the DSP(s), generates each mobile and/or nomadic device location relative to a single one of the respective seat positions and/or seats, and according to the LER. The one or more and/or at least one waveguide(s) and antennas are combined to be and/or are directionally oriented with respect to a corresponding single seat position and/or seat, such that the waveguide(s) establish the LER to be limited to each respective seat position, including the driver zone, and/or each seat, including the driver seat, for each antenna of each sensor group.
Such directionally oriented antennas and waveguide(s) are also configured to cooperate with the controller(s), also in combination with one or more of the DSPs and each sensor group, to generate the respective locations of each of the one or more mobile and/or nomadic devices, relative to each respective seat position and/or seat in the cabin, including the driver zone and seat, and according to the LER of the antennas and/or waveguide(s).
In the contemplated modifications wherein the waveguide(s) and antennas are integrated into the headliner of the cabin, and/or directionally oriented, each sensor group is located and positioned to be above and corresponding to a single seat position and/or seat in the cabin, including the driver zone and seat. The additionally described arrangements are similarly modified and configured when each sensor group is integrated as part of a single seat.
In additional variations, the sensor groups each include one or a respective DSP coupled to each of the different frequency tuned antennas, which antennas each may also include a respective waveguide. Each DSP is coupled to one antenna and integral or integrated waveguide, and the combination is tuned to one of the different frequencies. As with other arrangements, each combined signal processor, antenna, and waveguide, in combination with the controller(s), are also further configured to detect a respective communication protocol being utilized on the one different frequency, by one or more of the mobile and/or nomadic devices.
In other adaptations that include methods of controlling the vehicle and operation of the various configurations and arrangements, the controller(s) and sensors groups, including the DSPs, antennas, and waveguides, are further configured to autonomously generate the vehicle and mobile device commands, in response to the detected and/or generated location and a mobile device connection status. Whether the sensor groups and included components are integrated into the headliner, seats, and/or positioned proximate to the seat positions, the controller(s) are cooperatively are configured for generating the respective locations of each of the mobile devices, relative to each corresponding single seat of the seat positions, and according to the directional orientation of the antennas and waveguides and/or LER.

Such protocols, standards, and/or messaging formats are utilized for purposes of enabling various aspects of the disclosure and are known to those having knowledge in the relevant technology.
A number of international standards organizations are also involved in the field of technology and have generated various V2X resources such as SAE telematics and related standards J2945 and J2735: “On-Board System Requirements for V2V Safety Communications Standard,” SAE J2945/1_201603, available from standards.sae.org/j2945/1_201603/, and “Dedicated Short Range Communications (DSRC) Message Set Dictionary Standard,” SAE J2735_201603, available from standards.sae.org/j2735_201603, and others available from topics.sae.org/telematics/standards/automotive.
The SAE J2735 standard describes, defines, and specifies messages and data elements that make up messages/dialogs specifically for use by vehicle, infrastructure, and other off-board applications that utilize 5.9 gigahertz (GHz) DSRC for Wireless Access in Vehicular Environments (WAVE) communications systems. Such WAVE communications and related systems are described in more detail in various standards and reports established by and available from the Institute of Electrical and Electronics Engineers (IEEE) as described below. See, for example, standards.ieee.org, and more specifically, IEEE standard 1609, entitled, “Guide for Wireless Access in Vehicular Environments (WAVE) Architecture,” which is available from standards.ieee.org/develop/wg/1609_WG.html.
The IEEE 1609 WAVE standards enable and define an architecture and a standardized set of communications services and interfaces that enable secure V2V and V2I wireless communications. These standards enable a range of transportation and navigation applications, including vehicle safety, automated tolling, enhanced navigation, and traffic management, among others. The IEEE 1609 Wave capabilities are utilized in conjunction with others directed to various aspects of network and communications standards and architectures, including those managed by the IEEE 802 local area network and metropolitan area network (LAN/MAN) standards committee, which can be found at www.ieee802.org, as well as standards.ieee.org.
IEEE Standards 802.11 support software and firmware communications services of IEEE 1609, and enable data link media access control (MAC) and physical layer (PHY) capabilities, such as wireless local area network (WLAN) data communications in various frequency bands. The 802.11 standard is entitled “IEEE Standard for Information technology—Telecommunications and information exchange between systems—Local and metropolitan area networks—Specific requirements Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications,” and is available at ieeexplore.ieee.org/document/7792308.

The capabilities and configurations described in connection with any specific micro-processor-based controller as contemplated herein may also be embodied in one or more other controllers and distributed across more than one controller such that multiple controllers can individually, collaboratively, in combination, and cooperatively enable any such capability and configuration. Accordingly, recitation of “a controller” or “the controller(s)” is intended to refer to such controllers, components, subsystems, and systems, both in the singular and plural connotations, and individually, collectively, and in various suitable cooperative and distributed combinations.

The controllers communicate with one or more controller-based input/output (I/O) interfaces that may be implemented as single integrated interfaces enabling communication of raw data and signals, and/or signal conditioning, processing, and/or conversion, short-circuit protection, circuit isolation, and similar capabilities. Alternatively, one or more dedicated hardware or firmware devices, controllers, and systems on a chip may be used to precondition and preprocess particular signals during communications, and before and after such are communicated.

Each of such devices, components, processors, microprocessors, controllers, microcontrollers, memories, storage devices, and/or media may also further contain, include, and/or be embedded with one or more basic input and output systems (BIOSs), operating systems, application programming interfaces (APIs) having, enabling, and/or implementing remote procedure call (RPCs), and related firmware, microcode, software, logic instructions, commands, and the like, which enable programming, customization, coding, and configuration, and which may be embedded and/or contained in at least one of and/or distributed across one or more such devices, among other capabilities.
In this arrangement, VSC 140 and VCS 145 cooperatively manage and control the vehicle components and other controllers, sensors, and actuators, including for example without limitation, PCM/MCM/BCM 135, and/or various others. For example, the controllers may establish bidirectional communications with such internal and external sources, and communicate control commands, logic, and instructions and code, data, information, and signals to and/or from engine 115, EM 120, batteries 130, and PCM/MCM/BCM/power electronics 135, and other internal and external components, devices, subsystems, and systems. The controllers also may control and communicate with other vehicle components known to those skilled in the art, even though not shown in the figures.

The phrases “vehicle-based” and “onboard” refer to devices, subsystems, systems, and components integrated into, incorporated about, coupled to, and/or carried within vehicle 100 and its various controllers, subsystems, systems, devices, and/or components. In contrast, the phrase “offboard” is directed and contemplates such controllers, subsystems, systems, devices, and/or components being located external to and/or remote from vehicle 100.
For additional examples, VCS 145, GUIs 200, and other controllers of vehicle 100, may include, incorporate, be paired to, synchronized with, and/or be coupled with vehicle-based multimedia devices 215, auxiliary input(s) 220 and analog/digital (A/D) circuits 225, universal serial bus port(s) (USBs) 230, near field communication transceivers (NFCs) 235, wireless routers and/or transceivers (WRTs) 240, such as “Bluetooth” and Bluetooth low energy (BLE) devices, that enable wireless personal and local area networks (WPANs, WLANs) or “WiFi” IEEE 802.11 and 803.11 communications standards, and/or analog and digital cellular network modems and transceivers (CMTs) 245.
Such CMTs 245 utilize voice/audio and data encoding and technologies that include for example, cellular technologies that are managed by the International Telecommunications Union (ITU) as International Mobile Telecommunications (IMT) standards, which are often referred to as global system for mobile communications (GSM), enhanced data rates for GSM evolution (EDGE), universal mobile telecommunications system (UMTS), 2G, 3G, 4G, 5G, long-term evolution (LTE), code, space, frequency, polarization, and/or time division multiple access encoding (CDMA, SDMA, FDMA, PDMA, TDMA), and similar and related protocols, encodings, technologies, networks, and services.

With continuing reference to the various figures, including
The controller(s) 140, 145 and others, and transceiver(s) AT are configured to detect W Ss and to connect to nearby, or proximate, or distant, wired and wireless external, off-board network devices, which are transmitting such WSs that are in-range of transceiver(s) AT. The transceiver(s) AT are also configured to detect and connect to third-party, off-board, external devices such as nomadic, portable, and/or mobile or nomadic mobile devices 275, both internal to and within cabin 155, and external to vehicle 100.
For further example without limitation, many such transceiver(s) and/or antennas AT of vehicle 100 are WiFi and/or Bluetooth and BLE devices, which are configured according to the various standards described elsewhere herein. In one arrangement, for example without limitation and as depicted in
These WRTs 240, CMTs 245, WiFi sensors 280, and/or Bluetooth/BLE sensors 285 (hereafter also referred to collectively herein as “BT” sensors 285), and cellular sensors 290 are configured with effective and/or limited effective ranges (hereafter LERs), which are predetermined distances over which sensors 280, 285, 290 can detect and/or communicate with the various contemplated mobile and nomadic devices NMDs 275, when located with cabin 155 of vehicle 100. Such sensors 280, 285, 290 are configured to be insensitive to and unable to detect and communicate with such mobile and nomadic devices 275 beyond the near field communication range and/or LER, according to the configuration of the sensors groups, sensors, and related components.
An exemplary, schematic depiction of a representative LER is depicted in the various figures, including for example
For further examples, BLE sensors 285 are configured with a low power BLE configuration that limits communications between sensors 285 and BLE components of NMDs 275 in a near field communication range within about one meter. In other arrangements, controller(s), DSPs, and/or WiFi and cellular sensors 280, 290 are modified with ATs that limit reception of electromagnetic emissions from NMDs 275 that are within a near field communication range of about one meter or so. In other examples, sensor groups 175 and constituent sensors 280, 285, 290, DSPs, ATs, and related components are configured to have limited sensitivity to electromagnetic emissions from NMDs 275 by incorporating one or more and/or at least one antenna construction(s) that include respective directional antennas ATs and/or waveguides 295.
Such directional capabilities and directionally oriented configurations include, for example, implementing such antennas ATs and waveguides 295 to adjust sensitivity and responsiveness to electromagnetic energy in certain preferred directions that establish a predetermined shape and distal extent of LER, as is described elsewhere herein. For example, antennas ATs and waveguides 295 of sensor groups 175 are in one arrangement mounted and/or integrated with headliner 160 to emit and receive such electromagnetic energy from NMDs 275 that are located within the LER, which LER projects downwardly relative to headliner 160 and towards seat positions and seats 165. In other variations, antennas ATs and waveguides 295 of sensor groups 175 are mounted and/or integrated within and/or adjacent to seat positions and seats 165, and directionally oriented to project the LER upwards and/or forwards from a position on the seats 165 and towards NMDs 275 when carried by or located upon or near a driver and passenger that may be seated.
As shown in the figures, waveguides 295 may be for purposes of example but not for purposes of limitation, substantially conically shaped, which configures the volumetric shape of LER to be similarly and substantially lobed and/or conically shaped. However, in other possibly preferred arrangements, cylindrical, slotted masks, emitter/reflector elements, and other types of waveguides 295 may be utilized, according the various principles of antenna design known generally by those skilled in the art.
A number of antenna technologies are suitable and/or modifiable according to the disclosure for utilization as omnidirectional and directionally oriented antennas AT and sensors 280, 285, 290, tuned to the different BLE, WiFi, and cellular frequencies, and LERs described herein, and include for purposes of illustration and example, without limitation, those described in U.S. Pat. Nos. 5,532,709, 5,583,510, 5,777,583, 5,867,131, 5,898,404, 5,898,405, 5,943,017, 5,990,838, 6,005,519, 6,025,811, 6,054,955, and 6,052,096, among others.
Many vendors offer a variety of original equipment manufactured antennas AT, waveguides 295, and DSPs, which can be utilized as available and/or modified according to the disclosure to have omnidirectional and/or directionally oriented configurations that establish the LERs and other capabilities of the disclosure. For example, antennas AT and DSPs that may be utilized and/or modified for purposes of the disclosure includes Vishay DSPs and a Vishay VJ5106W240 series antenna, available from Vishay Intertechnology, Inc., Malvern, Pa., USA. Other exemplary DSPs and antennas include those available from: Texas Instruments, Inc., Dallas, Tex., United States, and include for example the AN-1811 antennas; NXP Semiconductors N.V., Irvine, Calif., United States; Molex, Inc., Lisle, Ill., United States; and DSP Group Inc., Los Altos, Calif., United States, among others.
Waveguides 295 are modified and configured as radio frequency (RF) reflective and/or attenuation devices that are configured to enable specific LERs and corresponding lobe shapes, omnidirectional, and/or directionally oriented configurations, which are associated with each of sensor groups 175, and the incorporated ATs and sensors 240, 245, 280, 285, and/or 290, such that NMDs 275 can only be detected when located within predetermined, specific, respective LERs associated with the respective seat positions 165 (and DZs) and seats 165 (and DSs).
A number of waveguides and related technologies are contemplated for modification with the described antennas AT, and utilization according to the disclosure, and include, for purposes of example without limitation, those described and illustrated in U.S. Pat. Nos. 5,414,394, 5,717,411, 5,764,116, 5,945,894, and 6,044,192, among others. Many such contemplated waveguides 295 are modifiable according to the disclosure to have omnidirectional and/or directionally oriented configurations that also adjust and establish the LERs, and are available from a number of vendors, including for example Fairview Microwave, Inc., Allen, Tex., United States; L3 Narda-ATM, Patchogue, N.Y., United States; and Pasternack Enterprises, Inc., Irvine, Calif., United States, among others.
Each of such sensor groups 175 includes the described and contemplated antennas ATs and waveguides 295, configured as band pass filters, electromagnetically polarizing, electromagnetic energy shields, masks, and/or other constructions that limit, adjust, attenuate, augment, and/or amplify impedance, reception power, and responsiveness of ATs of sensors 240, 245, 280, 285, and/or 290, to electromagnetic frequencies emitted by the contemplated mobile and nomadic devices NMDs 275 when inside cabin 155 and within the LERs of each respective seat position and seat 165.
In further configurations of the disclosure, vehicle 100 includes the controller(s) coupled to DSPs and spaced apart sensor groups 175, which form sensor arrays 170 within cabin 155, and proximate seat positions and seats 165. The sensor groups 175 and constituent components are spaced apart in the arrays, in side to side and front to rear positions in the cabin 155, to include one or more group(s) 175 for each corresponding single seat and seat position 165, to enable DSPs to detect signals, signal strengths, within each LER and to enable generation of the locations of NMDs 275 utilizing any number of distance and triangulation techniques, as is described in various co-owned patents listed elsewhere herein.
Seat positions and seats 165 include the driver zone DZ seat position 165, as well as the driver seat DS 165. Each sensor group 175 includes different frequency tuned antennas AT and at least one waveguide 295, as described elsewhere herein. For example, and with continuing reference to
The connection status(es) CSTs for each of the mobile and/or nomadic devices NMDs 275 include, for example, data that identifies whether such NMDs 275 are connected to other, different NMDs 275, and/or wireless data communications devices or services within and/or external to vehicle 100. Such CSTs also include data that identifies the one or more different frequencies being utilized for the identified connections, which different frequencies can include, for further example, one or more of Bluetooth, BLE, WiFi, and/or cellular communications frequencies. The CSTs also include data that describes the communications protocols being utilized on such different frequencies, for each of such Bluetooth, BLE, WiFi, and/or cellular communications frequencies.
Keycode KC can include one or more authenticate codes, such as a key fob authentication code or other type of code, which may identify the mobile devices and/or NMDs 275 as being paired and/or registered with vehicle 100. For further example, such keycodes may include those described and contemplated in co-owned U.S. Pat. Nos. 8,836,491, 9,349,231, 9,369,830, 9,580,044, and 9,725,071, among others. According to the location of the NMDs 275 within cabin 155, and the keycode KC, the controller(s), such as VSC 140, VCS 145, are further configured to autonomously generate mobile device commands (MDCs) and/or vehicle commands (VCs), responsive to the locations and KCs. For example, when such NMDs 275 are detected to be located in DZ and/or DS 165, the controller(s) may autonomously generate MDCs to lock and/or inactivate one or more functions of the NMDs 275.
In other arrangements, the automatically generated MDCs may temporarily disable email, messaging, and/or other features and capabilities of NMDs 275. The disclosure also contemplates autonomously generating VCs, according to the KCs, and responsive to and when NMDs 275 are detected to be in the DZ and DS 165, to set driver preferences for vehicle 100, which for example may include setting preferences for infotainment system features and capabilities, as well as seat height, and vehicle performance preferences, which settings and preferences may be retrieved from repository 180 and/or additional data that may form a part of such KCs.
Further variations of the disclosure include the controller(s) configured to automatically generate the VCs to enable vehicle 100 to be started, when NMDs 275 are detected in DZ and DS 165, and include KCs that are registered and/or paired with vehicle 100 to enable NMDs 275 to function as the already described key fob. The controller(s) may also autonomously generate VCs to control a maximum speed of vehicle 100, to generate voice or other alerts reminding a driver to avoid using certain features of NMDs 275 during vehicle operation, and/or other VCs. Still other adaptations include the controller(s) configured to detect and generate locations of the NMDs 275 located in seats and positions 165 outside the DZ and DS 165, and to autonomously generate VCs and MDCs to enable capabilities for vehicle 100 and NMDs 275, including for example multimedia streaming (audio, video, data, etc.), extravehicular internet access, and other features and capabilities that may be otherwise unavailable to a driver of vehicle 100 during operation thereof.
Vehicle 100 is also adapted to include sensor groups 175 integrated into headliner 160 and/or seat 165, such that each sensor group 175 is positioned to correspond with respective seat positions and seats 165, including the driver seat DS 165 and driver zone DZ 165. As with other arrangements, the at least one waveguide(s) 295 are configured to establish the substantially limited effective range (LER) to be limited to each respective seat position and/or seat 165, for each of the antennas AT of each sensor group 175. In this configuration, the controller(s), such as controller(s) 140, 145, in combination with the one or more DSPs and each sensor group 175, are configured to generate the locations of each of the one or more mobile devices and NMDs 275 that are proximate to the seats and positions 165, and according to and within the LERs of the antennas AT and sensors 240, 245, 280, 285, and/or 290.
The locations are generated relative to each seat position and seat 165, including driver zone DZ and driver seat DS 165. One or more of the controller(s) and/or DSPs of each sensor group 175, and antennas AT and sensors 240, 245, 280, 285, and/or 290, are configured to detect signals within the LERs, and/or signal strengths, of at least one and/or one or more of the different frequencies of NMDs 275, and to generate the locations of NMDs 275 relative to the seat positions and seats 165. An example of such signal and signal strength detection and location generation utilizing such controller(s), antennas ATs, and sensors 240, 245, 280, 285, and/or 290, includes the technologies and capabilities contemplated and described in co-owned U.S. Pat. Nos. 9,224,289, 9,516,492 and 9,612,797, among others.
As described, the sensor groups 175 are each positioned to correspond to the respective seat positions and seats 165 in cabin 155, such that the at least one and/or one or more waveguides 295 are directionally oriented to establish the LERs to correspond to each respective seat position and seat 165. Consequently, the controller(s), in combination with the DSP(s), generates the location of each mobile device and NMD 275, relative to a single one of the respective seat positions and seats 165, according to the LER.
The disclosure also contemplates each of the described arrangements, modifications, and variations configured with methods of controlling vehicle 100 and operation of the various controller(s), sensor groups 175, sensors 240, 245, 280, 285, and 29, antennas ATs, waveguides 295, and related components and systems, and for autonomously generating the locations of NMDs 275 and MDCs, VCs, and other commands. Such automatic generation of MDCs and VCs is in response to the detected and generated locations of NMDs 275, and the connection status(es) CST(s), and keycode(s) KC(s) detected and/or received from mobile devices and NMDs 275.
In the described and contemplated configurations of vehicle 100, including sensor groups 175 and included components being integrated into headliner 160, and/or seats and seat positions 165, the controller(s), antennas ATs, DSPs, and sensors 240, 245, 280, 285, 290, are cooperatively are configured for generating the respective locations of each of the mobile devices/NMDs 275, relative to each corresponding single seat 165 of the seat positions 165, as a function of and according to the directional orientation of antennas ATs and waveguides 295 and the correspondingly established LERs.
