Omron has developed an RFID reader/writer compatible with both the existing 13.56 MHz and proposed UHF frequency bands. In addition, the company has also developed a UHF band IC tag that uses proprietary IC chip ultrasonic bonding technology.
The reader/writer is equipped with antennae compatible with both frequencies making it capable of communication with IC tags conforming to ISO (18000-6, 18000-3) standards. In addition, it adopts TCP/IP protocol for connecting to upper equipment, making the reader easier to build into existing networks.
Although the UHF band is not authorised for IC tag applications in many countries, including Omron’s home country of Japan, it is expected that radio laws and regulations will be modified allowing tags to use the 950 to 956-MHz UHF band.
With the acceptance of UHF band IC tag usage, communication with IC tags over a much wider range of applications becomes possible, and it is anticipated that practical applications such as freight management for goods distribution will expand exponentially.
