2.4 GHz & 433 MHz Long Range RFID Technologies

All 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.

Long range RFID systems are generally called Active RFID systems. Active RFID systems have three essential parts; a reader, antenna, and a tag. Active RFID tags are equipped with their own power source in the form of an internal battery that enables them to have extremely long read ranges and sometimes even powering sensors (motion, duress button, temperature, humidity, etc).

Typically, active RFID tags are powered by a battery that will last around 5 years, but when the battery fails, the active tag will need to be replaced. Some tags allow for replaceable batteries that is a cost saving option.

433 MHz Active RFID

Our OEM 433 MHz tags and readers provide superior long distance reads in very demanding environments, reading through concrete and water and many other Industrial and Natural barriers. Our 433 MHz solutions provide accurate, real-time capabilities for detection, tracking, control and monitor a wide variety of Industrial, Marine, Mining, Healthcare, Vehicle and Personnel. This Dynamic Asset Management can be applied to operations and processes in a wide variety of industries and applications.

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 un-powered) 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.

Which results in distances over 3 KM (1.86 Miles) being possible with the right antennas.

Safety & Controlled Environments

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.

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

Active Tag Sensors and Features

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

Protecting Assets, Saving Lives

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.
Ideal for:
Office and Warehouse Personnel Tracking
Vehicle Availability

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.
Ideal for:
Cloud Chain

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. Motion sensing tags allow us to specify beacon durations when an asset or personnel is moving or not to conserve battery. We can also combine motion sensing with a duress button to allow any personnel to send a signal out to the reader that they need assistance which can trigger events in software for others to be notified.
Ideal for:
Facility Asset Tracking
Remote Asset Tracking

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 outside of the area you can have an alarm sound or have a health care giver return the patient to the controlled area.
Ideal for:
Personnel Tracking and Management

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 application 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.

RFID Antenna UHF 433 MHz

Antenna selection is critical to getting maximum read rate success. You need to match the antenna(s) to the specific application requirements and to the physical environment. We offer antennas that can range in size and shape- directional and omni-directional depending on the need of your application or even specific area within your deployment area. You can learn more about selecting the right antenna(s) in our RFID Reader Antenna Tutorial.

With the correct combination of tags and reader deployments, our solutions can locate your assets or personnel quickly and easily. The active monitoring means that you have a real time inventory of your tagged assets and personnel that is updated without any required effort on the part of your staff. Combine that with portable readers to go outside of your monitored zones to find missing assets or personnel quickly and easily.

Active Tag 2.45 GHz RFID

Numerous different configurations are available for 2.4 GHz readers and active tags. Most of the active readers can read up to 100 tags simultaneously. 2.4GHz RFID Active Tags can be configured to activate when moved, send a signal at predetermined intervals, record temperatures and more. Active tag RFID is also ideal for Real-Time Location Tracking (RTLS) projects.

This is a promising new technology which could add new functionality into RFID systems. We'll continue to publish updates as this technology advances towards commercial viability.
