Frequently Asked Questions
What is the read sensitivity of the Impinj M800 Series?
The Impinj M800 Series achieves -25.5 dBm read sensitivity, delivering up to 2 dB improvement over standard Gen2 implementations through Gen2X enhancements and AutoTune V3 technology.
What is the difference between M830 and M850 chips?
The M830 provides 128-bit EPC memory with no user memory, while the M850 offers 96-bit EPC memory plus 32 bits of user memory for additional application data storage.
Does the Impinj M800 support Gen2v2 privacy features?
Yes, the M800 Series supports EPCglobal Gen2v2 Untraceable and Short-range privacy features for consumer privacy protection, plus Impinj Protected Mode for tag data protection.
What is AutoTune V3 in the Impinj M800?
AutoTune V3 is Impinj's automatic RF tuning technology that optimizes the chip's impedance match to the antenna, improving read range and reliability across varying tag designs and operating conditions.
Is the Impinj M800 compatible with standard Gen2 RAIN RFID readers?
Yes, the M800 is fully backward-compatible with ISO 18000-63 and EPCglobal Gen2 readers, while offering enhanced performance when used with Gen2v2 or Gen2X-enabled readers.
What is FastID on the Impinj M800 Series?
FastID is a Gen2X feature that enables high-speed tag reading for rapid inventory operations, reducing the time required to read large populations of tags in retail and logistics applications.
