AgDataOne's LiveTrack™ incorporates active RFID technology and web based applications/interfaces built on open systems to fulfill the requirements of the USDA/USAIP animal identification plan.


This system provides individual animal data-collection and reporting tools and is capable of tracking the nation's cattle and swine supply, which is fundamental to controlling any disease threat, foreign or domestic.
By providing real-time source details, production details, immunization records, and custody information, the occurrence of and therein the rapid containment of animal health emergencies (such as foot-and-mouth disease or BSE) is realized.
The AD1 ear tag/ transmitter is a high-performance synthesized ASK/OOK 450>1000Mhz low power Transmitter. (1mW of output power) This unit is capable of sending serial data at up to 10,000 bits/second. Due to the transmitter being completely self-contained, requiring an antenna as the only additional RF component, the sizing becomes appropriate for medium/large animal usage. This unit is programmed with a unique ID number during Fab, which will become the animal tracking ID.

The AD1 receiver utilizes an advanced single-conversion superheterodyne architecture. Transmitted signals enter the module through a 50-ohm RF port intended for single ended connection to an external antenna. RF signals entering the antenna are bandpass filtered and then amplified by an NMOS cascode Low Noise Amplifier (LNA). The filtered, amplified signal is then down-converted to a 10.7MHz Intermediate Frequency (IF) by mixing it with a low-side Local Oscillator (LO). The LO frequency is generated by a Voltage Controlled Oscillator (VCO) locked by a Phase-Locked Loop (PLL) frequency synthesizer that utilizes a precision crystal reference. The mixer stage incorporates a pair of double balanced mixers and a unique image rejection circuit. This circuit, along with the high IF frequency and ceramic IF filters, reduces susceptibility to interference. The IF frequency is further amplified, filtered, and demodulated to
recover the baseband signal originally transmitted. The received signal is then run through an anti-collision algorithm to insure a single count of any unique ID and to weed out spurious signals from outside sources. These two units provide a reliable serial link capable of transferring data over line of site distances in excess of 3,000 feet.
