1. A monitoring system comprising a master device adapted for wireless communication with two slave devices each having a sensor adapted for acquiring a respective physiological signal,
wherein the master device is adapted for
providing synchronization signals to the two slave devices, and
instructing each of the two slave devices to acquire the respective physiological signal based on timing instructions,
wherein each of the two slave devices is adapted for
receiving a synchronization message,
setting a time anchor point based on the synchronization message,
measuring the respective physiological signal by means of the sensor according to the received timing instructions at a predetermined point of time relative to the time anchor point that is the same for each of the two slave devices so as to synchronize measurement of the respective physiological signals between the two slave devices, and
transmitting the acquired respective physiological signal wirelessly to the master device, and
wherein the master device comprises a processor adapted for processing the acquired physiological signals acquired by the sensors of at least two slave devices in order to extract a measure for a physiological parameter.
