# RFID 865-868 MHz: Technical Specifications and Applications ## Introduction to RFID 865-868 MHz Systems RFID 865-868 MHz systems operate within the UHF (Ultra-High Frequency) band, which is widely adopted for item-level tracking, logistics, and supply chain management due to its longer read range and faster data transfer rates compared to lower frequency RFID. In my experience deploying these systems across retail and warehouse environments, I've found their performance in bulk reading scenarios to be transformative for inventory accuracy. ## Technical Specifications and Parameters **TIANJUN RFID Reader TJ-RU868 Specifications:** - Operating Frequency: 865-868 MHz (Region-specific, EU compliant) - Chipset: Impinj R2000-based module - Processor: ARM Cortex-A8, 1GHz - Memory: 512MB DDR3, 4GB Flash storage - Communication Interfaces: Ethernet (10/100/1000 Mbps), RS-232, RS-485, WiFi 802.11ac, Bluetooth 4.2 - RF Power Output: Adjustable from 10dBm to 30dBm (0.01W to 1W) - Read Range: Up to 12 meters (dependent on antenna and tag) - Supported Protocols: EPCglobal UHF Class 1 Gen 2, ISO 18000-6C - Antenna Ports: 4 RP-TNC connectors - Dimensions: 220mm × 160mm × 40mm - Operating Temperature: -20°C to +55°C - Power Supply: 12V DC, 2A **TIANJUN Passive UHF Tag TJ-TAG868 Specifications:** - Chip: Alien Higgs-3 (ALN-9640) or equivalent - Memory: 96-bit EPC, 128-bit TID, 32-bit user memory - Frequency Range: 865-868 MHz - Read Sensitivity: -18 dBm - Write Sensitivity: -15 dBm - Operating Temperature: -40°C to +85°C - Dimensions: 100mm × 20mm × 0.5mm (standard inlay) - Material: PET substrate with aluminum antenna - Data Retention: 10 years - Write Cycles: 100,000 cycles *Note: These technical parameters are reference data.
