Abstract
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 both the old and the new time slots until the transmitter confirms that it has made the switch.
