A company named Mojix announced today a radically different approach to RFID tag reading that, if it can deliver as promised, has the chance to cause dramatic shifts in the RFID market, and potentially spur RFID deployment in distribution.
The company was formed in 2004 based on research from founder and CEO Ramin Sadr, who was involved in NASA programs related to deep space communications with satellites. That work employed technology that could pick up very faint radio signals and isolate them from a complex mix of other space “noise.”
Fast forward more than a decade later, and Sadr’s company has expanded on that knowledge to bring to market a new system that changes the paradigm of passive RFID technology.
To date, so called “passive” tags readers, such as those following the EPC standards, have combined the “exciter,” which energizes the tags so they can communicate data with the reader, which accepts and processes an activated tag’s signal.
As shown in the figure below, the Mojix technology separates those tasks, deploying a network of stand alone exciters that work in conjunction with just a few readers (or even just one reader) that, according to the company, have read ranges dramatically higher than readers available to date – a capability derived from the space communications technology that was capable of picking up very faint wireless signals.
The company says it will guarantee a read radius of 600 feet for a single STAR reader, which (using the “pi R squared formula) delivers a total read range of approximately 250,000 square feet. That’s as much as 100 times the read range of standard passive RFID readers.
