UHF RFID Reader
UHF RFID Reader
UHF RFID Reader is a technology widely used in the luxury products and fashion retail sectors. This technology can be utilized for various applications including inventory tracking and anti-counterfeiting.
The AD9361 is a highly integrated RF transceiver that includes an RF transmitter modulator, local oscillator (LO), and receiver analog baseband front end. It uses an external LO source and a GaAs pHEMT LNA with 0.8 dB NF.
1. Low power consumption
While LF and HF technologies require battery power to operate, UHF tags generate their own energy through radio waves. This helps to reduce the overall system cost. Additionally, UHF tags do not require line of sight like barcodes and can be read at distances from inches to over 120 feet, depending on the tag’s design.
While metal, water, and other elements can interfere with the signal, many RFID solutions are designed to address these challenges. With the right antenna tuning and RF front end, these pitfalls can be overcome for reliable UHF RFID reading.
As a result, UHF RFID reader technology is ideal for warehousing applications including cycle counts and tracking inventory in real-time. By using a rugged tablet with a UHF RFID UHF RFID Reader reader, warehouses can save time and labor in performing these operations. Ultimately, this allows for more efficient warehouse management and supports “smart” industrial production. By streamlining processes, RFID can help reduce costs while providing more visibility to inventory and reducing the risk of human error. DT Research’s UHF RFID readers are built with this in mind, combining high-performance computing and a rugged design that’s simple to use.
2. High speed
Compared to HF tags, UHF readers deliver high speeds, allowing you to read more items at once. This makes it ideal for warehousing and logistics applications where inventory counts need to be updated quickly to ensure accurate, real-time information.
To achieve these speed requirements, a high-performance UHF reader needs to have a good signal-to-noise ratio and an extremely low noise floor. The RF front-end block diagram uses an ADF9010-based transmitter modulator and ADC, ADL5382 demodulator, and ADL9963 receiver baseband filter and PGA to meet system-level performance requirements.
Reading a tagged item moving at high speeds requires thorough testing to optimize your setup. The first step is to experiment with the number of antennas used – the goal is to set up a perfectly spaced read zone so that one of the antennas sends the signal and energizes the tag, while another is able to receive the response without interference.
The next step is to test the angle of each antenna – you want to make sure they are positioned to optimally see the tagged item as it moves past. This will help you achieve the best signal-to-noise ratio and lowest noise floor.
3. High accuracy
Unlike barcode scanners which require direct line of sight, UHF RFID readers can accurately detect the backscattered signal of an RFID tag at long distances. This makes them a suitable choice for applications that have to deal with obstacles such as metal or water.
A key benefit of RFID technology is that it can provide real-time data that can help warehouses track inventory, identify and locate items and optimize inventory management processes. This data is available on handheld devices, such as rugged tablets, so that warehouse managers have a precise picture of what’s in the store and where it is at any given time.
In an RFID system, the ring oscillator of the digital baseband module has a high requirement for clock stability. To meet this need, a parallel voltage stabilizing and hard-limiting protection circuit is designed. Additionally, an improved feedback amplitude shift keying (ASK) demodulation circuit is designed, which improves the modulation depth and makes it easier to demodulate the RF signal. The sensitivity analysis results are also improved, resulting in better performance.
4. Easy to install
UHF RFID readers are easy to integrate and connect into existing infrastructure, such as access control systems. This helps you keep costs down and ensures the system is up and running quickly.
Whether you’re using RFID tags to track items within your warehouse or to deliver ‘buy online, pick in-store’ customer service, UHF RFID can help you improve productivity and accuracy. This technology offers an increased read range compared to low-frequency (LF) and high-frequency (HF) technologies, making it ideal for tracking large quantities of products or goods.
uPASS Reach logs vehicles as they pass by, helping you to identify who is in which car park and how many cars are entering and exiting. This makes it perfect for enabling secure entry to car parks and keeping traffic moving, even in peak hours. The reader is also able to limit the number of cars entering from a particular organisation, so you can be confident that only authorized people are using your parking space. It’s also great for preventing unauthorized users from accessing your site. This is especially important for protecting sensitive areas such as hospitals, airports or ports.
5. Low maintenance
UHF readers use long-range backscatter UHF RFID Reader technology to communicate with RFID tags without the need for line-of-sight, powering and focusing. This minimizes maintenance needs and downtime, which saves you money on both operations and capital expenditures.
RFID tags come in a variety of form factors and price ranges, from paper-thin labels/inlays to hard tag, which is more durable with a tougher exterior. The cost of UHF tags is lower than many alternatives, which allows you to tag more of your inventory and assets, increasing visibility into them.
Hospitals can track the location of equipment, medical supplies, critical documents and patients to drive productivity, patient safety and care quality up, and costs down. Similarly, airlines can streamline operations by enabling their employees to quickly locate and track baggage — so customers can get to their destinations faster and with less stress.
UHF readers operate in the radio frequency (RF) band and can be powered by a continuous wave (CW) transmission or by a radio-frequency identification system (RFID) signal. Choose a reader with the connectivity type that works best for your environment, depending on whether you’re using a wireless or wired connection and how long you need data to be transmitted.
