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 other technologies cannot meet 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.


433 MHz RFID

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 it listens for the transmissions sent by the tags. This allows the reader to detect weaker signals, sent with greater strength by the battery powered tag.

Which results in distances over 1 KM (0.62 Miles) being possible with the right antenna's

Sensors & Inputs

Battery powered tags are excellent for situations where you also want to collect information or allow the wearer to signal for help. Since they are not reliant on power from a reader to function, battery powered tags allow for duress buttons or heart rate monitoring in hospitals.

They also allow for temperature, g-force, or any other sensor input to be monitored and sent along with it's unique ID when the tag "beacons".


Safety & Controlled Environments

The unique characteristics of the 433 MHz we provide also make it suitable for environments where interferance or electro-static sensitivity prevent most other electronics such as airports or specialized checmical storages. The sealed tags emit a signal well below any regulatory guidelines, making them safe for use in areas where cell phones must be powered down.

The nature of the signal is also fairly unique in that it is able to pass through quite a large amout of rock, concrete, steel, or water. Making it beneficial for finding victims in mining accidents or avalanches.
