Abstract

The system for wireless transmission of medical data comprises a piece of transmission equipment carried by the patient which comprises a unit for differential amplification and band filtering, a unit for rejection of interference noises, particularly the sector and its harmonics, existing in the band of the useful signal, an amplification circuit with automatic gain control and a modulator receiving a carrier frequency, for example microwave at 2.45 GHz and the useful signal, in analog or after a digital conversion and optional processings. The system also comprises a suitable receiving station. The carrier frequency can be either generated in the transmission equipment, or in the receiving station which then transmits the nonmodulated carrier for the transmitters that are associated with it.
