Track Boxes operate using 2.4GHz for communication, and  can be set to one of 8 channels and tracking mode on Transponders should be activated on the same channel. Since these are the same 2.4GHz channels used by transponders for communication with active timing systems, the channel used for tracking mode should be different from those used for timing points to prevent saturation of the 2.4GHz channel. 

When active the Track Boxes are constantly waiting to receive Track Pings from transponders which have tracking mode activated. The range of the antenna ensures that Track Pings should be received within a minimum radius of 50m, in clear environments with little interference this range may be even wider.

Since Track Pings are sent in a short interval (interval depends on the transponder and the current status), the Track Box is likely to receive multiple Track Pings from each transponder. To optimise the accuracy and reliability of data the Track Box uses a detection algorithm to only send the most accurate time or recently seen transponders. 

For each Track Ping received the Track Box also sends an acknowledgement to the Transponder, this ensures the transponder's tracking mode remains activated according to the tracking mode time limits.

Times will be sent in batches, the frequency of which depends on the number of Track Pings being received. If no Track Pings are being received then the Track Box will only communicate with the server every 4 minutes.
