Radio Frequency Identification (RFID)

RFID is a form of wireless technology that uses low-power radio frequency to communicate data. There are two forms of RFID – active RFID and passive RFID. Link Labs uses a form of active RFID called RTLS.

How RFID Works for Asset Tracking

RFID uses Internet of Things (IoT) technology to identify assets like inventory, equipment, or even people. New versions are continually being developed to improve their capabilities.

Through various means of RFID, such as active and passive, users have the power to select the option that works best for them.

Frequency-based technology
RFID is a method of sending or receiving messages from asset tracking tags using specific frequencies. RFID doesn’t require continuous transmission of information.

Passive RFID
RFID technology is a battery-free process whereby a reader sends out a radio frequency signal that essentially “wakes up” the tag. A great example of this is going through toll booths.

Active RFID
Active RFID leverages batteries in tags and often works in concert with Bluetooth or Bluetooth Low Energy (LE), though other options are available. These systems are battery-powered sensors that connect to various access points throughout an area (like a building) and transfer data to the cloud.

Active RFID Range
Active RFID range can be greater than 100 feet between the RFID tag and reader. This allows Active RFID systems to scale easily since you could potentially 10,000 square feet with one Active RFID reader and a few reference points.


Industries that Benefit from Active RFID

Active RFID has use cases with companies across a variety of industries that have gained benefit from the use of this type of technology solution.
