Ultra High Frequency (UHF) Radio-Frequency Identification (RFID)

Ultra-High Frequency (UHF) is a Radio-Frequency Identification (RFID) based tag technology that enables UHF RFID devices to communicate with UHF RFID tags and other UHF RFID devices at close-to-long range for Connected Things projects. Adhering to the GS1 Generation 2 (Gen2) standard, this technology ensures global interoperability and improved performance within the UHF spectrum, typically 860 to 960 MHz. The standard facilitates faster data transfer rates and extended read ranges, crucial for effective inventory tracking, asset management and supply chain optimization across various sectors. With GS1 Gen2 compliant chips, UHF RFID tags can store unique identifiers and information, accessible by UHF RFID readers without necessitating direct line-of-sight, thereby streamlining data collection and exchange processes.

Benefits of UHF RFID

The utilization of Ultra-High Frequency (UHF) RFID technology brings forth a multitude of benefits across various industries, primarily due to its long-range reading capabilities, high-speed data transmission, and ability to read multiple tags simultaneously. This efficiency in operation not only enhances inventory management and asset tracking processes but also significantly reduces manual labor and errors associated with traditional barcode scanning. UHF RFID’s adaptability allows for seamless integration into existing systems, offering a scalable solution that can be customized to meet the specific needs of different projects. Moreover, its robustness and durability ensure reliable performance in diverse environmental conditions, thereby optimizing the overall efficiency and cost-effectiveness of operational workflows.


The range capabilities of UHF RFID systems significantly depend on the type of hardware used, particularly the choice of readers and antennas. Short-range readers, often utilized for close proximity applications such as access control and item-level tracking, can read tags within a few centimeters to a meter. In contrast, long-range readers and antennas are designed for applications requiring broader coverage, such as warehouse inventory management and vehicle tracking, extending the read range up to several meters or even tens of meters. The specific range achievable is influenced by factors including the power output of the RFID reader, the sensitivity and design of the antenna, environmental conditions, and the type of RFID tag in use. This variability in range capabilities allows for UHF RFID technology to be tailored to a wide array of applications, ensuring optimal performance based on the specific requirements of each project.
