The module communicates with the portable device via an interface, wherein said portable device further comprises at least one secondary wireless transmitter/receiver module comprising a diversity antenna and communicating with said main transmitter/receiver module via a direct data link external to said portable device. Thus, flexibility, exchangeability and upgradeability of the portable device are increased.
