1.0 Introduction
1.1 Fundamentals
IDENTEC SOLUTIONS’ ILR
®
(Intelligent Long Range
®
) technology is the next generation of
long range RFID (Radio Frequency IDentification). The objective is wireless and automated
data collection over large distances.
HOW RFID WORKS
Data is transmitted via high frequency radio waves between a tag and an interrogator.
Information stored on the tag can be read and modified. Data can be exchanged over long
distances, even in the presence of extreme operating conditions such as dust, dirt, paint or
oil.
The core element of the system is the active ILR tag, which can communicate large amounts
of data (up to 32 kBytes) at a rapid rate of transmission over very long distances (up to 100
meters). A sophisticated anti-collision handling algorithm enables the interrogator (i-PORT)
to record data simultaneously from hundreds of these tags within seconds. Connection of
the interrogator to a host computer system permits global data accessibility via a variety of
software platforms.
CHARACTERISTICS OF ILR:
• UHF Frequency (868 / 915 MHz)
• Long read and write range of 30 meters (optional up to 100 meters)
• Variable read range from just a few meters up to 100 meters
• Large storage capacity (8 kB or 32 kB)
• Temperature monitoring and recording (optional)
• Highly visible LED “pick-by-light” (optional)
• Long battery lifetime (up to 6 years)
• Anti-collision process and multi-tag handling
1.2 System Overview
IDENTEC SOLUTIONS’ ILR-System consists of 4 main components:
• Active tags (also called transponders) with internal power supply, which are used to
identify goods or to store data and histories
• Interrogator (i-PORT; fixed-mounted) and handheld devices (mobile), which exchange
information with the tags and host computer systems
• Antenna types for different applications
• A central computer system as basis for control and monitoring
