What is the read range of RFID tags? The read range depends on the type of tag, frequency, and environmental conditions. Passive tags typically have a range within 10 meters, while active tags can reach 100 meters or more. #1. What Is Read Range? Read range is the distance from which an RFID tag can be detected. The read range expresses the distance from which the tag receives just enough power to be activated to send back a signal to the reader. #2. How Is Read Range Determined? Generally, the manufacturer spec sheet includes RFID read range information.Table of Contents. What is RFID? How does RFID Work? What is RFID Used For? Types of RFID Frequencies. Ultra-High Frequency: Passive vs. Active. Passive RFID Focus. What is in an RFID System? What is an RFID Tag? What is an RFID Reader? What is an RFID Antenna? Other RFID System Components - Printers.

RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person. Here are the 6 factors that most commonly affect RFID read range. Contents. RFID Antenna Selection – Gain, Beamwidth. RFID Tag Selection and Positioning – Size, Orientation, Angle, Placement. RFID Reader Settings – Transmit Power, Receive Sensitivity. Antenna Cable Selection – Power Loss. Environment Factors – Metal, Water. 1.
Read Range – Read range describes the hypothetical range at which an RFID system can read a tag in a given direction in an ideal environment. When used in terms of RFID tags, it is the hypothetical range at which an RFID tag can respond in an ideal environment. Read range refers to the maximum distance within which an RFID tag can detect radio waves from an RFID reader. Whenever the tag is within this range, it becomes active and allows the reader to capture the data.
In general, low-frequency and high-frequency tags tags are read from within three feet (1 meter) and UHF tags are read from 10 to 20 feet. Readers with phased array antennas can increase the read range of passive tags to 60 feet or more.RFID, which stands for radio frequency identification, is a form of wireless communication that uses radio waves to identify and track objects. There are a number of forms of RFID technology on the market today. The most recognizable include low frequency (LF), high frequency (HF), and ultra-high frequency (UHF).
