GAO RFID announced its active 433 MHz interrogator designed to provide real-time data collection in wireless applications such as the tracking and identification of cargo, vehicles, personnel or other assets.

The long range active reader, model 227007, utilizes ultra-high frequency (UHF) RFID technology to provide accurate, real-time data collection; coupled together with an integrated antenna to transmit and receive data at distances of over 140 meters (460 feet).

Utilizing the ISO/IEC 18000-7 interface for RFID communications in the 433 MHz band, the GAO reader also boasts a 2 megabyte Flash program memory and 128 kilobytes of non-volatile memory. In addition, it supports the ability to chain several interrogators to a host interface for data transmission via RS232 interface, which provides the need for only one connection to power supply.

Employing a standardized anti-collision, multi-transponder-handling algorithm, communication to compatible RFID tags remains accurate even when thousands of transponders are within the reader’s range.
