Abstract
A wireless bidirectional communication system and method for tracking smart tags affixed to assets located within a defined area. Asset tracking is provided by a central processor operated by a user. The central processor combined with communication modules communicates with the system tags for deriving corresponding assets'"'"' locations. Communication is synchronized by way of broadcasting a clock generator signal over the communication link. The broadcasted clock signal is further used by the system for generating distinct time slots assigned to a tag by demand. Synchronizing the communication between the tags and the central processor is beneficial for maintaining reliable and short messages across the data link and maintaining low power draw from the tag battery.
