Wat is UHF RFID?
Inhoudsopgave
Invoering
Did you know that UHF RFID systems can read up to 1,000 tags per second from over 10 meters away? That kind of speed and range is revolutionizing how companies track inventory, manage assets, and streamline supply chains.
UHF-RFID (Ultra-High Frequency Radio Frequency Identification) is a cutting-edge identification technology gaining momentum across various industries. From retail and logistics to healthcare and agriculture, its ability to enable fast, contactless data exchange is transforming how businesses operate.
Whether you’re exploring RFID for the first time or looking to deepen your understanding, this guide will walk you through what UHF-RFID is, how it works, its applications, and why it’s a must-know technology in 2025.
Wat is UHF RFID?
UHF RFID, short for Ultra-High Frequency Radio Frequency Identification, is a wireless communication technology that uses radio waves to identify and track tags attached to objects. It’s one of the three major frequency categories in RFID technology — the other two being Low Frequency (LF) and High Frequency (HF).
UHF typically operates within the 860 MHz to 960 MHz range and is well known for:
- Longer read ranges (up to 12 meters or more)
- Faster data transmission
- Bulk reading capability
In simpler terms, UHF RFID is like a digital “barcode on steroids” — no line of sight needed, and hundreds of items can be read instantly.
Hoe werkt UHF RFID?
To understand how UHF RFID functions, let’s look at its core components:
- RFID-tags: Contain a microchip and antenna that store data.
- RFID-lezers: Emit radio waves and receive data from tags.
- Antennes: Boost the signal between tags and readers.
- Middleware/Software: Processes and manages the data collected.
There are two main types of UHF RFID-tags:
- Passive UHF Tags: Rely on energy from the reader’s signal; cheaper and commonly used.
- Active UHF Tags: Battery-powered; suitable for long-range and real-time applications.
Key Functionality:
- The reader emits a signal in the UHF band.
- The tag receives energy, powers on, and sends its data back.
- The reader collects this data and sends it to a backend system for processing.
The system can read multiple tags simultaneously, even at high speeds — making UHF RFID ideal for dynamic environments like conveyor belts or fast-moving inventory.
Benefits of UHF RFID Technology
Why is UHF RFID gaining so much traction? Because it solves real-world tracking and automation challenges. Here are the standout benefits:
- Lang leesbereik: Up to 12 meters, even in rugged environments
- Bulk Reading: Read hundreds of tags in seconds
- Kostenefficiënt: Passive tags are affordable for large-scale use
- Realtime zichtbaarheid: Instant updates on inventory and asset movement
- Non-Line-of-Sight: No need to scan directly like with barcodes
- Scalability: Suitable for small operations or global supply chains
In short, it boosts efficiency, accuracy, and automation — key pillars for modern businesses.
Common Applications of UHF RFID
UHF RFID has emerged as a core technology in modern automation and tracking systems, offering exceptional range, speed, and versatility. Its ability to read hundreds of tags simultaneously and at long distances makes it invaluable across a wide range of industries.

UHF RFID vs HF and LF RFID – Key Differences
| Functie | LF (Lage Frequentie) | HF (Hoge Frequentie) | UHF (Ultrahoge frequentie) |
|---|---|---|---|
| Frequentie | 125-134 kHz | 13,56 MHz | 860-960 MHz |
| Leesbereik | ~10cm | ~1 m | Up to 12 m |
| Gegevenssnelheid | Langzaam | Gematigd | Snel |
| Kosten | Laag | Gematigd | Varieert |
| Gebruiksgevallen | Dieren volgen | Contactloos betalen | Supply chain, retail, logistics |
UHF RFID offers the longest read range and fastest performance, making it ideal for fast-paced environments and high-volume tracking.
UHF RFID Standards and Regulations
Standards govern global use of UHF RFID to ensure compatibility:
- EPCglobal Gen2 / ISO 18000-6C: Industry standard for passive UHF RFID
- FCC (USA): Operates in 902–928 MHz
- ETSI (Europe): Operates in 865–868 MHz
- Other Regions: Vary slightly depending on telecom regulations
It’s crucial to ensure compliance with regional frequency regulations when deploying UHF RFID globally.

Challenges and Limitations of UHF RFID
Like any tech, UHF RFID isn’t perfect. Here’s what to consider:
- Metal and Liquid Interference: Can block or distort signals
- Omgevingsfactoren: Extreme temperatures can affect performance
- Line-of-Sight Limitations: Tags in dense stacks may not be read reliably
- Upfront Cost: Infrastructure setup can be expensive
- Data Overload: Requires robust software to handle large-scale data collection
But with careful planning, these limitations can be minimized or mitigated entirely.
Future Trends in UHF RFID (2025 and Beyond)
UHF RFID isn’t just here to stay — it’s evolving fast. Trends include:
- Integration with IoT: Smart sensors + RFID = powerful data insights
- Cloud-Based RFID Systems: Manage tags from anywhere

Veelgestelde vragen over UHF RFID-technologie
What does UHF RFID stand for?
UHF RFID stands for Ultra-High Frequency Radio Frequency Identification. It refers to RFID systems that operate in the 860–960 MHz frequency range and are capable of reading tags from several meters away.
How does UHF RFID work?
UHF RFID systems use radio waves to communicate between a reader and a tag. The reader sends out a signal that powers up passive tags, which then send their data back to the reader. This enables quick, wireless identification of objects without needing a direct line of sight.
What is the range of a UHF RFID system?
UHF RFID systems typically have a read range of 3 to 12 meters (10 to 40 feet) for passive tags. Active tags with batteries can extend the range significantly, sometimes up to 100 meters or more.
