Ultra High Frequency, or UHF for short, is an automated wireless communication technique that enables long-distance data reading. RFID is an automated identification system that uses tags to identify objects. Two sizable categories are created from the RFID tags:

passive tags: gadgets without a separate power supply

active tags: gadgets with an independent energy source

Three frequencies are primarily used by passive tags: ultra high frequency (UHF), high frequency (HF), and low frequency (LF).

Because UHF tags can read data at long ranges of 8 to 10 meters, they are effectively employed in the retail and logistics industries.

In the industrial sector, RFID tags using UHF technology are used for inventory management and logistics by utilizing portable handheld readers that can scan tags over long distances.

How UHF Technology Affects RFID

Three basic components make up the UHF technical system: an antenna, an RFID reader, and a tag, also known as a transponder. A microchip holding all the data is attached to the tag, and an RF antenna is used to send the data to the reader so it may be read and updated.

Electromagnetic waves are the basis of the technology’s operation, enabling this transmission even with devices lacking an independent power source.

Through the antenna, the reader creates an electromagnetic field that causes the tag’s spiral to generate a voltage, which feeds the chip and activates it. Utilizing the same spiral, the active chip transmits the data to the reader so that it may be read and processed by the reader.

Enhance Operational Effectiveness Using UHF RFID Technology

The significant rise in consumer product traceability requirements and the necessity for operational simplicity to boost manufacturing and distribution process efficiency are both directly related to the significant development of e-commerce.

The retail industry effectively uses the RFID system in conjunction with UHF technology to provide real-time enormous data collection, enhance supply chain traceability, and boost operational efficiency across a range of commercial applications.

Any kind of commodity, from pharmaceuticals to enormous cellars of wine to the opulent clothing of the fashion industry, might have a tag attached to it.

The following are the key benefits of integrating RFID technology with UHF technology:

It enhances inventory management procedures.

By assisting in stock reduction, UHF devices increase the accuracy of home control data. More than 100 tags can be scanned by an RFID scanner in a second. It is possible to locate and identify items with ease, which facilitates speedier order fulfillment.

Utmost Trackability

Using an RFID tag, a product may be distinguished from thousands of others that are identical to it, and the supply chain’s whole history—from the place where raw materials are mined to the point where the product is delivered to the customer—can be recreated.

Speed of reading and product administration

When RFID tags and UHF technology are combined, it is possible to read several tags at once at a distance and without a target at a rate of several hundred per second. The tag must come within the antenna’s field of view in order for the readings to be obtained. Up to 50% less time may be spent managing warehouses with this technology.

UHF System Application in the Industrial Sector

There are many applications and uses for the RFID system that combine UHF technology in the retail industry and other domains.

Although the RFID market is heavily utilized in the luxury and apparel fashion sectors, it is expanding rapidly in all other industrial sectors as well, with over a billion tags put only on these kinds of applications. These sectors include automotive, aviation, cosmetics, logistics, pharmaceuticals, and food. It is currently essential for a company’s quick and effective warehouse management and logistics, and it is widely used in the transportation sector as a particularly helpful monitoring system.

Through the use of an IP or WiFi network, an almost instantaneous inventory is possible thanks to the many, quick, and up-to-date readings of the tags placed to items. The most sophisticated and effective automation in the industrial sector up to this point is the development of an RFID gateway that makes use of UHF (or HF, depending on the demands).

RFID is widely employed in luxury goods and fashion retail, and it offers an excellent anti-counterfeit and anti-shoplifting system. It is also effectively used to track and monitor the vital cycle of commodities or items.

RFID readers are a dynamic technological system that may be used for recognizing patients and their clinical folders in the medical-sanitary sector. They also speed up data transfer and control operations across the many firm sectors.


UHF technology: what is it?

Ultra High Frequency, or UHF for short, is an automated wireless communication technique that enables long-distance data reading. UHF tags are widely used in the retail and logistics industries because they can read data at a distance of up to 8 or 10 meters.

What are the differences between UHF and NFC?

Two advancements made possible by RFID technology are UHF and NFC. RFID HF (High Frequency) is another name for NFC (Near Field Communication), and UHF stands for Ultra-High Frequency.

A radio-frequency identification system is the foundation of both technologies: high frequency for NFC technology and extremely high frequency for UHF technology.

The primary distinction lies in the frequency at which they operate, and consequently, in the transmission distance, data reading, and processing.
