More Information
Summary:The invention concerns an underwater transceiver device, communications system and method of communicating sensor data underwater. The transceiver device comprises a sensor unit or a sensor connection for an external sensor unit for providing a sensor value and a communication unit functionally connected to the sensor unit or connection and comprising means for wirelessly transmitting the sensor value to another underwater device as data packets according to a timing scheme. According to the invention, the communication unit further comprises means for wirelessly receiving data packets of other underwater devices, and means for adjusting the timing scheme based on data packets received so as to avoid simultaneous transmitting of underwater devices. The invention enables energy-efficient and robust communications between diving equipment.
