Abstract
An entertainment system includes radio access nodes (RANs) spaced apart from each other and a location measurement node. The location measurement node includes a memory and at least one processor. The memory contains a seat layout map identifying an arrangement of seats and locations of the RANs relative to the seats. The processor measures distances between the RANs and a transceiver device located at a seat among the seats arranged according to a seat layout map residing in memory, and retrieves from the seat layout map, the locations of the RANs relative to the seats. The processor identifies one of the seats within the seat layout map where the transceiver device is located based on comparison of the measured distances and the retrieved locations of the RANs relative to the seats, and stores in the memory an identifier for the transceiver device associated with an identifier for the seat.
