A marine propulsor comprises: a stationary part and a movable part which is movable relative to the stationary part; and a wireless communication system, comprising at least one transmitter which is disposed in the movable part and is configured to transmit an electromagnetic data signal and at least one receiver which is disposed in the stationary part and is configured to receive the electromagnetic data signal. The wireless communication system includes a diversity scheme for mitigating multipath distortion of the electromagnetic data signal between the at least one transmitter and the at least one receiver.

Wireless communication system and method

There is provided a wireless communication system for a marine propulsor, comprising: a transmitter; a receiver; and a waveguide, arranged to convey an electromagnetic data signal between the transmitter and the receiver; wherein the waveguide comprises an electrically non-conductive solid or liquid medium for propagating the electromagnetic data signal.

Wireless communication system

There is provided apparatus for propagation of a wireless signal through a barrier comprising a first antenna for location on a first side of the barrier, a second antenna for location on a second side of the barrier and a waveguide. The waveguide comprises a conducting member passing through the barrier between the first and second sides. The conducting member is held within an insulator sleeve such that it is spaced from a surrounding metal wall of the waveguide. A wireless signal received by the waveguide on the first side of the barrier is transmitted through the barrier by Transverse Electro-Magnetic (TEM) mode propagation along the waveguide is re-radiated on the second side.
