New tech cancels signal collision

Technology developed by researchers at Missouri University of Science and Technology (Missouri S&T) in Rolla, Missouri, significantly increases read rates, reduces read errors, and improves system coverage in RFID systems, reports MoreRFID.

Missouri S&T is seeking partners to commercialise the patent pending technology which eliminates RFID signal collision by employing two different schemes to adjust RFID reader power in response to interference levels.

The technology uses distributed adaptive power control and probabilistic power control schemes to adjust RFID reader power output in response to interference levels caused when multiple RFID readers try to read RFID tags and by RFID antennae in close proximity to each other.

Kovio has developed a silicon ink-based RFID tag and the company's printed silicon RFID platform for item-level intelligence, says Nanotechnology Now.

This revolutionary platform enables the development of affordable item-level RFID intelligence solutions for various markets, including retail, pharmaceuticals, transit, logistics and asset management.

Kovio's silicon RFID tags reduce the overall cost of tag manufacturing.

GAO RFID has released an active long-range tag, the GAO 137003, says New Design World.

The RFID tag has an expandable memory of 32 000 bytes for massive information storage, an LED for visual recognition, and an internal sensor for temperature monitoring.

The reader conveys data using progressive UHF radio frequency technology at a distance of up to 100 feet from a handheld device or up to 300 feet from a fixed interrogator.
