Abstract
The present invention is directed to managing power consumption in a wireless frequency hopping communication among a plurality of nodes. For example, the present invention is directed to features such as reducing power consumption of an individual node within a wireless communication system by powering on the transmitter/receiver of the node only when actual transmission/reception is required.
Claims9
Method for controlling communication of frequency hopped radio signals among a plurality of nodes in a communication system, comprising the steps of:
- initializing the communication system by synchronizing the nodes to a first node;
- placing at least one of said plurality of nodes into an inactive state of reduced power consumption at a first time, wherein said at least one node saves timing information of said first node corresponding to said first time;
- and
- configuring at least one of said first node and another node in said communication system to determine that said at least one node is in said inactive state by monitoring messages from other nodes in said communication system.
