The Field-Mapper is a worldwide battery free UHF RFID power meter for Gen 2 RFID Systems. This can be used to check for low power areas or dead spots across an RFID tracking point. It's an essential tool for setting up robust RFID tracking points for applications like sports events where vehicles, metal barriers, buildings, cables, people, drones and other RF power sources may be present


  • No Battery – It uses the RF power
  • Pocket sized and hand held
  • 7dB attenuation switch for antenna testing
  • Wide frequency range
  • Works with all Gen2 UHF RFID Readers

What it can do
