Transceiver circuitry, portable communication device and method for performing radio communication

The present invention relates particularly to transceiver circuitry, a portable communication device and to a method for performing radio communication. Transceiver circuitry comprises a first portion having a first modulation means operating at a first order of modulation, for transmitting and receiving voice signals; a second portion having a second modulation means operating at a second order of modulation, for transmitting and receiving digital signals at a higher data rate than is achievable by the first portion; and a data conversion means operable to convert from or into voice signals intended for processing by the first portion into or from digital signals for processing by the second portion.
