Portable communication device with tunable antenna and method of operating such portable communication device
First Claim
1. A hearing aid, comprising:
- a transceiver unit for establishing a wireless communication link using a digital modulation scheme with a packet-based frequency hopping scheme including an advertising channel, wherein the transceiver unit is configured to receive audio data;
an antenna;
an antenna tuning circuit physically coupled to the transceiver unit and the antenna for tuning the antenna,wherein the transceiver unit is adapted to estimate strength of signals received in the advertising channel and to transmit a control signal partially based on the estimated strength of signals;
wherein the antenna tuning circuit is adapted to tune the antenna partially based on the control signal, wherein tuning the antenna includes reducing a frequency range for transmission or increasing transmission strength of signals associated with the advertising channel, andwherein the transceiver unit is adapted to judge whether an interferer is present during the estimation of the received strength of signals in the advertising channel and to use the respective estimation of the received strength of signals only in case that it has been judged that there is no interferer present.

Abstract
A portable communication device having a transceiver unit (30) for establishing a wireless communication link (16) using a digital modulation scheme with a packet-based frequency hopping scheme including at least one advertising channel, an antenna (32), an antenna tuning circuit (34) connected to the transceiver unit and the antenna for tuning the antenna, and a control unit (36) for controlling the antenna tuning circuit. The transceiver unit is adapted to estimate the strength of signals received in the at least one advertising channel and to supply the control unit with a signal representative of the estimated signal strength in the at least one advertising channel. The control unit is adapted to control the antenna tuning circuit such that the antenna is tuned according to the signal representative of the estimated signal strength in the at least one advertising channel.

15. A method of operating a hearing aid, the method comprising:
-
establishing a wireless communication link between a hearing aid and an external device by using a digital modulation scheme with a packet-based frequency hopping scheme including an advertising channel; estimating, by the hearing aid, strength of signals received in the advertising channel, and tuning the antenna partially based on a signal representative of the estimated strength of signals in the advertising channel, wherein tuning includes reducing a frequency range for transmission or increasing transmission strength of signals associated with the advertising channel; decoding an audio data packet in the advertising channel during the estimation of the received signal strength; and determining an interferer is present based on determining the audio data packet has not been correctly received. - View Dependent Claims (16)
