RTLS BASICS
RFID
Automatic identification technology which uses radio-frequency electromagnetic fields to identify objects carrying tags when they come close to a reader.
. Tags: Electronic identifiers attached to the object that needs tracking. They store information and transmit feedback signals to reader. Reader: Portable or static device that sends radio wave signals to the tags. Computer (Hardware and Software): Used to encode tags, display and manipulate read and written data.
RFID tags operate at 3 different frequencies: - Low frequency (LF) signals can travel very short distances. Up to 10cm. - High frequency (HF) radio waves can travel up to 1m - Ultrahigh Frequency (UHF) waves can travel up to 10-30m. "Blinksight 200+mts".
Used to alert the users while they approach the tagged component. Whenever an specific item is needed, the handheld reader can be used to search the RFID tag that is associated with an specific object. It is a good fit for applications that don’t need to automatically track the movement of items.
