5.7GHz, 2.4 GHz & 433 MHz Long Range RFID Technologies

All three of these technologies use active (battery assisted) tags, which allow them to reaching distances of over 65 feet (20 meters) and can relay sensor information back along with their unique identification. This makes them ideal for situations where other technologies cannot meet the requirements. One such example would be in transit tracking of a shipment for temperature, tampering or g-force. The reader can then be integrated with GPS allowing the entire shipment to be tracked much more cost effectively than GPS tracking each container individually.Get more news about Long Range Rfid Reader,you can vist our website!

433 MHz will make up the bulk of this page due to it's significantly longer range, and more refined feature set thanks to it's much longer lifetime.

Development on 433 MHz RFID started in the early 2000's and is fundamentally different than other RFID technologies. In RFID it is almost always a passive (or unpowered) tag that is "excited" or powered by the readers signal. This allows the tag to respond with it's unique ID. The 433 MHz we offer does the exact oppose; The reader is powered but does not send any signal of it's own. Instead the readers listen for the transmissions sent by the battery powered tags. This allows the reader to detect far weaker signals, sent with significantly greater strength by the battery powered tag.
Designed for applications in Transportation, Mining, Emergency Evacuation, Supply Chain, Petrochemical, Healthcare, Manufacturing, Gated Communities, Education, and the Military. The unique characteristics of our 433 MHz technology make it suitable for environments where interferance or electro-static sensitivity prevent most other electronics such as airports or specialized chemical storages. The sealed ATEX certified tags emit such a low power signal that it is well below any regulatory guidelines, making them safe for use in static free areas where cell phones must be powered down.

Real-Time Location Tracking  (RTLS) accounts for nearly all active tag RFID systems. The active tag transmits its identity on a predetermined basis, and with the correct antenna placements you can determine the location of the active tag. Sensors can be added to the tags for real time temperature sensing and real time motion sensing.

Temperature sensing tags can be used to store temperature information on a timed basis and send the collected information to the active tag reader.  In addition the temperature sensing tag can be set up to set off an alarm condition should the limit be exceeded.

Motion sensing tags can be set up to transmit a signal when moved or signal until movement stops.  This is ideal for high value asset control where you want to know if an asset is moving so that you can determine if the movement is justified or an intrusion.

Patient tracking in health care facilities is also a common application for active RFID tags. Using a wrist band tag a patients movements within a certain location are known and if the patients goes oustide of the area you can have an alarm sound or have a health care giver return the patient to the controlled area.
Most of our 433 MHz line of tags can be enhanced with motion and temperature sensors, tuned for your specific needs.  If you want to track assets that can be moved but also can remain stationary for a period of time, then we can equip our Industrial Tags with motion detectors so that when motion is sensed the tag beacons differently thus sending a signal to your applicaiton that motion has been detected.  When the asset stops moving the sensor again changes it's beaconing characteristics and once again the application is aware that the asset has stopped moving.
