Benefits
- open architecture
- modular design
- at the permitted levels of radiation power the reading range is 3 times longer compared to other radio frequency identification technologies based on passive RFID tags
- low reader radiation level
- high radiation resistance of radiometers (up to 6 Us)
- high durability SAW RFID tags to high intensity electromagnetic fields
- wide temperature range of SAW RFID tags in extreme conditions (from -60 °C to + 125 °C)
- reader and RFID tags service life is at least 25 years
- high reliability
- high noise immunity (thanks to new encoding methods)
- impossibility of detecting by the method of nonlinear location
- impossibility to change the unique identification code of the SAW RFID tag without authorization
Scope
- transport
- industry (automotive, aviation, nuclear, chemical, etc.)
- agricultural industry
- logistics
Configuration
- reader
- reader antenna
- RFID tags (for a variety of Scope)
Principle of Operation
Passive acoustoelectronic RFID tags based on surface acoustic waves are applied for object radio frequency identification and mounted on the identifiable objects. Information about the object is read by the reader and transmitted to the control unit. The request and response exchange occurs between reader antennas and transceiving antennas built in RFID tags.
RFID Scope of Application::
- stationary reader is used to control moving objects in the controlled area. The reader is installed at the post, the reader antennas are installed above the controlled perimeters. Up to two antennas can be connected to a single reader
- mobile reader is used for identification marking of cargo and modular units
