For instance, if a first user needs to share the available bandwidth with other users intending to utilize services requiring high bandwidth, that will likely affect the bandwidth available to the first user. Typically, it is not practically possible to fully eliminate such effects with improvements in communication infrastructure, such as adding radio base stations or Wi-Fi access points to an area.
  • a wireless communication device in this example the AR glasses 10 of Figure la, improves this issue as will be described in the following.

  • Figure 2b illustrates the AR glasses 10 complying with the recommendation received in step S103 by instructing the user to orientate the AR glasses 10 in accordance with the recommendation, which in this example implies turning left in step S104 towards the radio base station 25 in order to direct the front antennas of the AR glasses 10 towards the radio base station 25.

  • the recommendation would not necessarily have contained instructions as to which direction the user should turn (i.e., 90° to the left), but may have only instructed the user to position herself somewhere at the left-hand side of the area 15.
  • the recommendation may have contained the instruction to orient the right-hand temple of the AR glasses 20 towards the radio base station 25 given that the right-hand temple of the AR glasses 20 comprises a transceiver for 4G LTE communication as previously discussed.
  • the supervision device 30 is enabled to provide a recommendation on how the user should orientate the AR glasses 10 for satisfactory quality of service as regards the wireless communication to be performed, in this case by turning 90° to the left.
  • the user may well have turned away from the radio base station 25, and may in such case even have failed to access or maintain the desired service with an expected quality of service.
  • the embodiment provides for a guidance system that informs user(s) utilizing wireless communication devices regarding favourable orientations (and possibly also positions) for wireless communication in order to provide a sufficient quality of service.
  • the users can thus move to more preferable positions and/or turn in more preferable directions, and even avoid unfavourable positions and/or directions.

  • a further recommendation taking this into account may thus be provided as the user moves along.
  • Such a recommendation may, e.g., be based on a route which the user is following to a target destination, e.g., provided by a routing service like Google Maps.
  • a route which the user is following to a target destination e.g., provided by a routing service like Google Maps.
  • the user is about to enter a cafe where she is planning to have a holographic or 3D video session with a couple of friends, or to play a certain Extended Reality (XR) game demanding certain performance from a local network.
  • the recommendation will preferably enable the user to find the “best” seat, or a sufficiently good seat, in the cafe given the current application, short-time future intentions of the user, device capability, battery status, etc. For example, a low battery level may result in a lower bandwidth being provided to the AR glasses 10.
  • different frequency bands may be assigned to the different users participating in the XR game for a best experience.

  • the supervision device 30 has, e.g., two alternatives when providing the recommendation, where one of the alternatives will result in a scenario where the required quality of service cannot be attained, while the other alternative indeed will result in the required quality of service being attained, the supervision device 30 will recommend the second alternative. It may also be that a sufficient amount of radio resources cannot be allocated at some location or in some direction of the area 15 for an extended time period, which information may be included in the recommendation, thereby enabling the user to avoid such locations and directions.
  • the supervision device 30 provides two or more recommendations, in which case the AR glasses 10 may select from the plurality of recommendations being provided.
  • the recommendations could be to orientate in two slightly different directions and the AR glasses may select the recommendation that adapts best to the capabilities of the AR glasses 10, such as having the user orientate in a direction where 5G communication is possible rather than in a direction only allowing 4G communication.
  • the recommendations can be presented to the user that makes a choice based on, e.g., personal preferences, or the AR glasses 10 may select a desired recommendation based on, e.g., a current or future service to be accessed, or a route which the user is following (e.g., a route provided by Google Maps or a similar service).

  • an updated recommendation is provided to the second set of AR glasses 11 upon the first set of AR glasses 10 entering the area, for instance to move closer to the second radio station 26 in order to avoid possible interference from the first set of AR glasses 10.
  • the supervision device 30 in step S102 concludes that the first set of AR glasses 10 should be directed towards the first radio base station 25 and creates a recommendation accordingly, since the further set of AR glasses 11 already is communicating with the second radio base station 26, thus advantageously providing for a better balance of communication resources by sending that instruction to the first set of AR glasses 10 in step S103.
  • Figure 7b illustrates the first set of AR glasses 10 complying with the recommendation received in step S103 and instructing the user to turn to the left in step S104 towards the first radio base station 25 in order to direct the front antennas of the AR glasses 10 towards the first radio base station 25, while the further set of AR glasses 11 remains directed towards the second radio base station 26.
