Bi-directional communication system for logistic tracking
First Claim
1. A method of operating a bi-directional communication system between a plurality of communication devices which comprise at least one communication controller and a plurality of nodes including a first node, the method comprising:
- periodically broadcasting a beacon signal from said communication controller at a broadcast interval via a channel of a first host, said beacon signal containing a first address of said communication controller;
periodically scanning said beacon signal on said first host by said first node;
upon detecting of said beacon signal by said first node, transmitting an identification payload from said first node to said communication controller; and
upon receipt of said identification payload by said communication controller;
transmitting an acknowledgement signal to said first node;
wherein said acknowledgement signal further contains a command instructing at least one subsequent action to be taken by said first node;
wherein said at least one subsequent action is said first node entering sleep mode.

Abstract
The present invention provides a method of operating a bi-directional communication system between a plurality of communication devices, which comprises at least one communication controller and a plurality of nodes including a first node. The method includes periodically broadcasting a beacon signal from said communication controller at a broadcast interval via a channel of a first host. The beacon signal contains a first address of the communication controller. The method further includes periodically scanning the beacon signal on the first host by the first node. Upon detecting of the beacon signal by the first node, the first node transmits an identification payload to the communication controller. Upon receipt of the identification payload by the communication controller, an acknowledgement signal is transmitted to the first node.
