WE-T32K125The Dual Band Active RFID Tag is a battery powered active RFID tag. The tag has two operating frequency bands, 125KHz band and 2.4GHz band. The tag has location and inventory functions.

• The 4 GHz band is the main operating band for communication between tags and active readers;
• The 125 KHz band is used to wake up the dual-band tag that triggers the dormant state and receives the ID of the exciter;
• The operating mode of the tag is TTF (Tagged-To-Transmit-To-Transmit).

The label has 4 operating modes:

• LF Trigger Mode: The tag can be awakened from dormancy by the low frequency excitation signal from the exciter. The awakened tag receives the ID and check data from the exciter, and if the received data is correct, the tag sends the combination of the exciter ID and its own ID through the 4GHz channel. The data sent by the tag can be received by an active reader, and the exciter ID and tag ID are processed by the system software as the positioning information of the digital map;
• Timed Signal Mode: Normally, the tag is in hibernation mode in order to extend battery life. A dormant tag can be periodically woken up by the internal timer to enter the working mode. The awakened tag sends its own ID through the 4GHz channel, this data is called heartbeat packet, and the heartbeat packet interval can be set. Heartbeat packets can be used for real time monitoring of the tag;
• Alarm Mode: The tag uses a microswitch as an anti-removal alarm device. The switch is closed when the tag is mounted on an object, and once it is detached from the object, the switch opens and the tag sends out an alarm signal over the 4GHz channel;
• Search Mode: If you are looking for a tag in a poorly lit or complex environment, send a search command with the tag ID through the active reader, and when the tag being searched receives a search command matching its own ID, the tag's LED will blink, and this feature is optional.

The communication distance for the 4GHz channel ranges from a few meters to several hundred meters depending on the environment; the 125KHz channel has a trigger distance of 1-5 meters.
