Abstract
The method for positioning an anchor B in a system RA defined by an anchor A, the anchor A and the anchor B being outside of UWB range from one another, but in Wi-Fi range, the positioning method using mobile equipment (2) comprising a UWB communication module (5) and a Wi-Fi communication module (10). The measuring method include the steps of: evaluating, by using UWB signals, a position PMA of the mobile equipment (2) in the system RA; evaluate a position PB of the anchor B, by using UWB signals, if the mobile equipment (2) is located in UWB range of the anchor B, or by alternatively using Wi-Fi signals; deduce from the position PMA and from the position PB, a position PBA of the anchor B in the system RA.

A method for positioning an anchor B in a system RA defined from a position of an anchor A, the anchor A and the anchor B being UWB anchors, which each comprise a UWB communication module, which are each integrated in equipment comprising a Wi-Fi communication module, and which are in Wi-Fi range from one another,
- the positioning method using mobile equipment comprising a UWB communication module and a Wi-Fi communication module, and which is located in UWB range at least of the anchor A and in Wi-Fi range of the anchor A and of the anchor B,
- the positioning method comprising the steps of:
- evaluating, by the equipment integrating the anchor A, by using first UWB signals, a position PMA of the mobile equipment in the system RA;
- evaluating, by the equipment integrating the anchor A and/or by the equipment integrating the anchor B and/or by the mobile equipment, a position PB of the anchor B, by using second UWB signals, if the mobile equipment is located in UWB range of the anchor B, or by alternatively using Wi-Fi signals;
- deducing from the position PMA and from the position PB, a position PBA of the anchor B in the system RA.
Electrical equipment comprising an anchor A, a Wi-Fi communication module, and a processing unit, the anchor A being a UWB anchor, the processing unit 7 being arranged to:
- evaluate, by using first UWB signals, a position PMA of mobile equipment in a system RA defined from a position of the anchor A, the mobile equipment being able to comprise a UWB communication module and a Wi-Fi communication module and being able to be located in UWB range of the anchor A and in Wi-Fi range of the anchor A;
- evaluate, by the equipment integrating the anchor A and/or by equipment being able to integrate an anchor B and/or by the mobile equipment, a position PB of the anchor B, which is also a UWB anchor and which can be in Wi-Fi range of the anchor A, by using second UWB signals, if the mobile equipment is located in UWB range of the anchor B, or by alternatively using Wi-Fi signals;
- deduce from the position PMA and from the position PB, a position PPA of the anchor B in the system RA.
Mobile equipment comprising a UWB communication module, a Wi-Fi communication module, and a processing unit, and which can be located in UWB range at least of an anchor A and in Wi-Fi range of the anchor A and of an anchor B, the anchor A and the anchor B being UWB anchors, the processing unit being arranged to:
- evaluate, by equipment which could integrate the anchor A, by using first UWB signals, a position PMA of the mobile equipment in a system RA defined from a position of the anchor A;
- evaluate, by the equipment which could integrate the anchor A and/or by equipment which could integrate the anchor B and/or by the mobile equipment, a position PB of the anchor B, by using second UWB signals, if the mobile equipment is located in UWB range of the anchor B, or by alternatively using Wi-Fi signals;
- deduce from the position PMA and from the position PB, a position PBA of the anchor B in the system RA.
Equipment comprising a processing unit arranged to:
- evaluate by equipment which could integrate an anchor A, by using first UWB signals, a position PMA of mobile equipment in a system RA defined from a position of the anchor A;
- evaluate, by the equipment which could integrate the anchor A and/or by equipment which could integrate an anchor B and/or by the mobile equipment, a position PB of the anchor B, by using second UWB signals, if the mobile equipment is located in UWB range of the anchor B, or by alternatively using Wi-Fi signals;
- deduce from the position PMA and from the position PB, a position PPA of the anchor B in the system RA,
- the anchor A and the anchor B being UWB anchors which can be in Wi-Fi range from one another,
- the mobile equipment which could comprise a UWB communication module and a Wi-Fi communication module, and which could be located in UWB range at least of the anchor A and in Wi-Fi range of the anchor A and of the anchor B.
