# RFID 868MHz: The Ultimate Guide to European UHF RFID Technology ## What is RFID 868MHz? **RFID 868MHz** refers to the Ultra-High Frequency (UHF) RFID technology operating at the 868 MHz frequency band, which is the standard allocation for RFID applications in Europe and many other regions following ETSI regulations. This technology enables wireless data transmission between RFID tags and readers over distances ranging from a few centimeters to over 10 meters, depending on the equipment and environment. I personally began working with **RFID 868MHz** systems over a decade ago when implementing inventory tracking for a retail client, and I was immediately impressed by its read range and multi-tag reading capabilities compared to lower frequency alternatives. ## Technical Specifications and Performance Metrics ### **RFID 868MHz Reader Technical Parameters** | Parameter | Specification | |-----------|---------------| | Frequency Range | 865-868 MHz (EU) | | Operating Channels | Typically 10-15 channels (ETSI) | | Maximum ERP | 2W (33 dBm) for EU region | | Modulation | ASK, PR-ASK, DSB-ASK | | Protocol Support | EPCglobal UHF Class 1 Gen 2, ISO 18000-6C | | Interface | USB, Ethernet, RS232, GPIO | | Read Range | Up to 12 meters (dependent on tag and environment) | | Anti-collision | Capable of reading 800+ tags per second | | Power Supply | 9-24V DC or PoE | | Operating Temperature | -20°C to +55°C | | Dimensions | Varies by model: Typical fixed reader 180mm x 140mm x 35mm | | Chipset | Commonly Impinj R2000, R420, or similar | *Note: These technical parameters are reference data.
