radio-frequency identification
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromag ...
(RFID) tags which perform a specific function when attached to metal objects. The ROM tags overcome some of the problems traditional RFID tags suffer when near metal, such as detuning and reflecting of the RFID signal, which can cause poor tag read range, phantom reads, or no read signal at all.
The RFID-on-metal tags are designed to compensate for the effects of metal. There are several tag design methods to create ROM tags. The original method was to provide a spacer to shield the tag
antenna
Antenna ( antennas or antennae) may refer to:
Science and engineering
* Antenna (radio), also known as an aerial, a transducer designed to transmit or receive electromagnetic (e.g., TV or radio) waves
* Antennae Galaxies, the name of two collid ...
from the metal, creating bigger tags. New techniques focus on specialized antenna design that utilizes the metal interference and
signal reflection for longer read range than similar sized tags attached to non-metal objects. RFID-on-metal transponders will continue to create new opportunities for users in a wide range of asset tracking and broader industrial applications. The main applications are asset tracking on servers and laptops in IT data centers, industrial manufacturing quality control and manufacturing, oil and gas pipeline maintenance, and gas cylinders.
The technology is evolving to allow transponders to be embedded in metal. The capability allows manufacturers to track small metal items from cradle to grave. The main focus for RFID inside metal is tool tracking, weapon tracking, and medical device quality control.
RuBee (IEEE 1902.1) on metal
RuBee
RuBee ( IEEE standard 1902.1) is a two way active wireless protocol designed for harsh environment and high security asset visibility applications. RuBee utilizes longwave signals to send and receive short (128 byte) data packets in a local region ...
is a wireless 132 kHz packet-based protocol, with range of few feet to 50 feet, is magnetic and has near zero Radio Frequency (E) energy. RuBee is often used when RF based systems have challenges in harsh environments especially on and near steel and metal. Because it is magnetic it has no multipath reflections so no nulls, and is no
blocked by steel water, snow or dirt. RuBee is in widespread use in industrial environments (over 1,500 sites) on heavy machinery (Injection Molding Machines and Tools ), in armories and many defense
applications.
