RFID Readers: Long-Range RFID Readers

Long range RFID Readers can read RF-transmitted signals from tags at long distances. They are instrumental in warehouses/distribution centres and help businesses gain real-time inventory visibility.

These wireless readers can also automate parking management, reducing labour costs. They can automatically identify vehicles and drivers to facilitate car parker entry/exit.

High Throughput

Article 266 300x200 - RFID Readers: Long-Range RFID ReadersUsing radio signals, long-range RFID readers transmit and receive data through an antenna that is integrated into the reader or attached to it externally. When an RFID tag comes within range, it automatically sends a signal to the reader with the required information, after which the read action is performed.

For instance, a driver can be identified at the gate of an airport to be given access. Or, an RFID system can verify a shipment and relay sensor data like temperature, g-force or tampering to a central control room.

High Accuracy

Long range RFID Readers accurately read ID tags, even in challenging environments. It makes them perfect for remote location asset tracking, secured access to a facility, accurate time tracking of vehicles or personnel, and more. SkyRFID offers a complete line of 433 MHz readers, tags (ATEX Certified) and antennas for use in any environment, including Intrinsically Safe – Atex Certification.

The detection performance of a long-range RFID sensor tag depends on the power density S of RF energy at a given read distance r from the RFID reader antenna and the radius of its detection area, modelled as shown in Figure 8.

The weights of the particles are updated with a probability proportional to their positions, using a measurement model in both the world coordinate system and robot coordinate system. The resulting algorithm estimates the part of the robot accurately and stably. Experimental results in Table 5 show that the eight HF-band RFID reader systems perform highly accurate self-localization, with errors more minor than 15 mm in the x direction and less than 25 mm in the y direction for both likelihood models.

Low Power Consumption

SkyRFID long-range RFID readers have been engineered to be durable and operate in all environments, including Intrinsically Safe – Atex certification. They detect and decode RF-transmitted signals from 1st Choice assets, vehicles and personnel tags.

In addition to RF read range and power efficiency, long-range RFID systems have a low total cost of ownership. It is especially important when deployed on a large scale in demanding applications like warehouses, vehicle yards and outdoor production sites.

Passive long range RFID readers tag offer a cost-effective solution for tracking pallets and RTIs in warehouses and vehicle yards. They also provide long read-range identification for work in process, dock door portals or any application where the location of the tags may change during production. In these cases, the reader can use different RF off-time parameters to decrease its power consumption without reducing the read range when no tags are in its field.

Long Lifespan

Long-range RFID systems use an antenna that is either integrated into the reader or connected to it externally. When a tag comes within range, it activates and returns a radio signal holding the required information. This information will be passed on to the user. It can be used for further action, such as access control for campuses and gated communities or vehicle and driver identification at airports.

Passive RFID tags have no battery but harvest energy from RF signals and use backscatter reflection techniques to send their data to the reader. Active RFID tags have batteries commonly found in toll passes and rail car tags. These can be read at highway speeds by the same readers and have a lifespan of about five years.

Using these readers with RFID cards or tags for doors and vehicle access gives you an easy-to-maintain system that can quickly let in vehicles and people. TPS also offers a hands-free parking solution that uses the same technology to allow only authorized people into your commercial or residential parking lot. So, if you want real-time inventory visibility, RFID is the answer.
