Which type of rfid tag can send a signal over a long distance?
What is long range RFID?RFID stands for radio-frequency identification. This technology is based on wireless identification that uses electromagnetic fields to identify and track objects. Whether it concerns vehicles or packed goods, RFID is able to automatically identify and track given objects and determine whether access is authorized. Show Every RFID system consist of three unique parts:
RFID systems allow for quick and easy identification of various entities, allowing for safer, faster and more reliable process automation and access control. Depending on the requirements of your security design, we would like to help you to find a fitting long range RFID system that works for you.
Long range RFID applicationsThe possibilities of long range RFID are numerous; ranging from access control for campuses and gated communities to vehicle and driver identification at airports. Find out in what circumstances long range RFID can be applied. Passive and active long range RFIDThere are three types of RFID systems that can be distinguished: passive RFID, semi-active RFID and active RFID. These technologies have unique specifications and are therefore suitable for different purposes. Knowing the difference helps you choose the best RFID system for your application. Passive RFIDPassive RFID systems make use of tags that do not have an internal power source. They are powered by the radio signals transmitted by the reader antenna. This guarantees a long lifetime. These tags use radio signal modulation to transmit information back to the reader. The read range relies on at which range the tags can still be powered and at which range the reader still receives the tag’s signal. Passive RFID systems are predominantly used for access control, supply chain management, file tracking and more. Semi-active RFIDSemi-active RFID systems use battery-powered tags but with no active transmitter. The tag does not draw power from the reader. It uses backscatter reflection techniques to transmit information back to the reader. This allows for a long read range without the high current consumption. Active RFIDActive RFID systems use battery-powered tags that broadcast their own signal with an active transmitter. These tags can actively transmit their signal to the reader. This allows for a long read range, but typically will have a limited lifetime compared to passive and semi-active tags. Long range RFID readersNedap offer a variety of long range RFID readers within two distinct technologies. Each technology comes with unique specifications that make it suitable for a wide variety of applications. Depending on the expected use and conditions, we advise you on what long range RFID reader and technology best fits your wishes. TRANSITOur TRANSIT technology is the leading platform for automatic identification of vehicles and drivers. This extremely robust long range RFID reader enables simultaneous identification of vehicles and drivers. This high-end reader is designed to perform well in high security applications, demanding vehicular access control applications and under harsh environmental conditions. TRANSIT has a read range up to 10 meters. Typical applications are airports, ports, mines and military bases. uPASSOur uPASS portfolio is our leading vehicle identification technology baed on UHF RFID technology where you can choose between different readers and tags. The uPASS long range RFID readers are perfectly suited for convenient yet secure access control in every parking facility, gated community and campus. Based on UHF RFID technology and using passive tags, uPASS is a cost-efficient yet valuable choice for a wide range of applications. Everything starts with a mesh network of active RFID readers (anchors) set up throughout your facility. These readers are strategically placed to provide complete coverage of the area. Each active RFID reader will always be scanning for the signal sent out by an RFID tag worn by staff or affixed to your equipment and vehicles. These tags are made up of a small antenna, sensors, RFID chip, and battery. The battery provides power allowing the RFID chip to transmit a radio signal actively. Some of the internal power sources on RFID tags can last for years before being replaced. RFID tags may transmit once every few seconds or minutes, depending on how often you want to receive movement data. The RFID readers may also have an internal battery that provides backup power for several hours in case of an outage. These signals sent out by the tags are picked up by the long range RFID readers placed around your facility. All data within the signal is converted into location data and sent back to RTLS software installed on a facility server. With this software, you can monitor the movement of everyone and all assets via the RFID tracker network. Litum’s RTLS software also allows you to create: Can RFID be read from a distance?Far-range UHF RFID tags can read at ranges as far as 12 meters with a passive RFID tag, whereas active tags can achieve ranges of 100 meters or more.
What is the maximum distance for RFID?Active RFID systems, on the other hand, can typically be read from 300 feet (90 meters) away, but many can now go up to 1,500 feet (460 meters) or more by employing signal repeaters.
What are the types of RFID tags?Each RFID type can be either active (powered), passive (un-powered) or semi-passive (battery-assisted).. Low-frequency (LF) RFID tags: 30 KHz to 300 KHz. ... . Ultra-high-frequency (UHF) RFID tags: 300 MHz to 3GHz. ... . Active, passive and semi-passive RFID tags.. What are the two types of RFID?There are two main types of RFID tags:. Active RFID. An active RFID tag has its own power source, often a battery.. Passive RFID. A passive RFID tag receives its power from the reading antenna, whose electromagnetic wave induces a current in the RFID tag's antenna.. |
