What read range can I expect from a UHF RFID reader?

Jul 23, 2026

Read range depends on multiple factors: reader output power (dBm), antenna gain (dBi), tag type and size, and environmental conditions (metal, liquids, temperature). Our Symo Series readers deliver read ranges from 0 to 30 meters depending on configuration.

For example, the FR54A fixed reader with Impinj E710 chip and a suitable antenna can read tags up to 30 meters in optimal conditions.Integrated readers like the IR38A with built-in 8dBi antenna typically achieve 0–14 meters. In real-world deployments, we recommend testing with your specific tags and environment. Factors like metal shelving, liquid-filled containers, and tag orientation all affect actual range.
