A wireless network is provided that uses pseudo-static time slots. These time slots remain fixed in time unless and until a network controller specifically changes them and the network controller subsequently receives confirmation of the change. Times and durations of the pseudo-static time slots are only changed in small steps as each relevant device in the network acknowledges the step. To aid in allowing full coverage even during a change of active devices, when a transmitter and receiver are moved to a new time slot, the receiver is set to listen to ...


1. A method of controlling a transmitter and a receiver to adjust transmitting and receiving times in a super-frame having a plurality of active time slots and one or more unused time intervals, the transmitter and the receiver both being initially assigned to a starting active time slot chosen from the plurality of active time slots, comprising:sending a first instruction from a controller to the receiver to listen for signals from the transmitter during both the starting active time slot and a target unused time interval chosen from the one or more unu...
