Grade and radio frequency identification

RFID is defined as the wireless use of electromagnetic fields to transfer data. Think of a retail environment here where the reader sends a radio signal to a tagged item of clothing and an alarm is triggered only when the tag is sensed in very close proximity to the designated choke point.

What are Real-Time Location Systems? RTLS on the other hand, is any solution that is used to automatically identify and track the location of an asset, individual or other objects in real time.

RTLS solutions consist of various tags and badges, platforms Wi-Fi, Infrared, Ultrasound, Radio Frequency, and othersnetwork appliances readers and excitersas well as other components like servers, middleware and end-user software.

Depending on the technology platform chosen, the system locates the tags within varying degrees of granularity. For example, with active-RFID location tracking, it can sometimes be difficult to determine if an object is on one side of a wall or another as RF signals have the ability to penetrate floors and walls.

Legacy IR technology requires a clear line of sight for the tags and sensors to communicate so if a badge is covered by a blanket or flipped around, the system may not function properly. Ultrasound, as a communications protocol, is slower with longer wavelengths than infrared, so it is generally unable to match the performance of other technologies.

Although Wi-Fi infrastructure is often pre-existing in healthcare facilities, accuracy is limited to as much as thirty feet, making its value as a location-tracking tool uncertain.

CenTrak specifically combines Gen2IR, a patented technology that does not face the same line of sight constraints as legacy IR, active-RFID, and Wi-Fi in order to deliver the levels of precision and flexibility that are unachievable by any single technology.Grade and Radio Frequency Identification.

A . A radio-frequency identification system uses tags, or labels attached to the objects to be identified. Two-way radio transmitter-receivers called interrogators or readers send a signal to the tag and read its response..

RFID tags can be either passive, active or battery-assisted passive. The IEEE Journal of Radio Frequency Identification (RFID) publishes peer-reviewed manuscripts addressing various aspects of RFID systems. The articles describe advances in theory, algorithms, design techniques, implementations, and applications of RFID systems.
