The invention concerns an arrangement for the localisation and identification of objects in one or several service regions defined by wireless networks in a room, and access to a contextual service for an approved object in the room, including;
- one or several identification elements (10) of short-range radio frequency type associated with the object that is to be identified and located
- a minimum of three first transmitters/receivers (20) of short-range radio frequency type that, deployed in the room, allow an external and an internal frame of reference (40; 40:1) to be formed in the room, whereby the geographical location of each first transmitter/receiver is known to the frame of reference
- calculation means (13) for the localisation of an identification element and the creation of measurement results based on distance or direction to the identification element on the receipt of a response to a request
- one or several second transmitters/receivers (30) that function at short-range radio frequencies and that can communicate with the said first transmitters/receivers
- calculation means (33) for the calculation of the position of the identification element based on measurement results that are obtained from the first transmitter/receiver (20). |
