1. A method of exchanging data packages between a first portable communication device and a second portable communication device over a bi-directional wireless communication channel, where at least one of the first and second portable communication devices comprises a hearing instrument, the method comprising:

  • generating, by the first portable communication device, a first plurality of data packages;

    transmitting the first plurality of data packages from the first portable communication device to the second portable communication device through a plurality of spaced apart frequency bands distributed across a radio frequency range of the bi-directional wireless communication channel;

    computing, at the first wireless communication device or at the second wireless communication device, transmission quality estimators for the respective spaced apart frequency bands;

    determining a favoured frequency band based on the transmission quality estimators; and

    transmitting, from the first portable communication device to the second portable communication device, a second plurality of data packages on the favoured frequency band, the second plurality of data packages comprising a first data package;

    wherein if the transmission of one of the second plurality of data packages fails, the method further comprises;

    selecting, in accordance with a frequency hopping key, a frequency band of the plurality of spaced apart frequency bands that is different from the favoured frequency band; and

    retransmitting the one of the second plurality of data packages on the different frequency band.
