Abstract
In a method of establishing communication between a primary node and secondary nodes over communications channels, the secondary nodes are placed in a sleep state in the absence of active communications and are responsive to a wake-up message transmitted over the one or more communications channels from the primary node to enter a wake-up state. A wake-up message is sent from an instigator at the primary node to a receptor at a said secondary node. The communications channels with the receptor at said secondary node are periodically sniffed for a valid wake-up message. In response to reception of a valid wake-up message the receptor places the secondary node in the wake-up state. The instigator and receptor employ a selected operational mode being defined by the timing of the wake-up message and sniff pattern at the receptor. The selected operational mode is changed to suit different channel conditions.
