A mobile telephone in which the electronic circuits of the telephone are separated into two units, one unit 1 being a handset containing the earpiece and microphone, the other unit 2 containing the transmitter, and any other circuit elements which generate large amounts of electromagnetic radiation. During operation, the transmitter unit is located at some suitable distance from the- head of the user to minimise the amount of radio energy impinging on the user's head, thereby reducing user health concerns. Further more, if the user is wearing a hearing aid, interference in the hearing aid caused by the telephone's emissions are reduced to an acceptable level. Speech and control signals are exchanged between the handset and the transmitter unit via a wire link or a wireless link consisting of an infra red link, a low power radio link, or some other arrangement which does not produce unacceptable levels of electromagnetic emissions. |
