Embedded rfid recorder in short-range wireless devices

Abstract

The invention relates to a portable communications device. The invention further relates to its use of and to a method of operating it. The object of the present invention is to facilitate adaptation of a communications device to its present environment, e.g. to facilitate spectrum sharing in short range communication devices. The problem is solved in that the portable communications device comprises a wireless communications interface for communicating with another device, a memory and an RFID-recorder for receiving an RFID-signal transmitted from an RFID-interrogator, wherein the device is adapted for storing individual received RFID-signals in the memory. An advantage of the invention is that it provides a relatively simple scheme for extracting information from a current environment of a portable communications device. The invention may e.g. be used for adapting listening devices, e.g. hearing instruments, headphones, or head sets to local, e.g. country specific, conditions or to operate in an efficient way under given interference conditions.
