Abstract

The present invention provides for a communication system for conveying biomedical data between a plurality of patient monitors and a centralized base station. The communication system includes a plurality of base transceivers within the base station. Each of the base transceivers is coupled with a dedicated transmit antenna and a dedicated receive antenna. The communication system additionally includes a plurality of remote transceivers each coupled with one of the patient monitors. Each of the remote transceivers communicates with a respective base transceiver. Each of the base transceivers may be interconnected via a common bus. The base transceivers and remote transceivers each have at least one tuning device controlled by a microcontroller for varying the center frequency thereof according to a hop sequence. The communication system may include a forward error correction device, a scrambler and a modem for providing GMSK modulation of the biomedical data.
