Abstract:
A wireless communication system comprises one or more control units operable to transmit control signals, a plurality of actuators responsive to the control signals, and a plurality of sensors operable to transmit sensor data used by the one or more control units in generating the control signals. Each of the sensors, actuators, and one or more control units are located at a fixed position in the system relative to one another. Each of the plurality of sensors and each of the plurality of actuators are coupled to at least one of the one or more control units via a plurality of wireless paths. Each of the plurality of sensors are operable to transmit the sensor data in an assigned time slot to at least one of the one or more control units over a plurality of wireless channels in each of the plurality of wireless paths. The number of channels in each of the plurality of wireless paths is determined based, at least in part, on a worst-case estimate of potential interference, and each of the plurality of sensors is operable to pseudo-randomly switch the plurality of channels over which the sensor data is transmitted.
