"Called Optag <http://www.optag-consortium.com/>, it would employ 
panoramic cameras and active 5.8 GHz RFID 
<javascript:OpenGlossary("RFID");> transponders with a 10- to 20-meter 
read range <javascript:OpenGlossary("read range");>."

"Real Time Location Systems" (RTLS) based on ACTIVE  RFID tags is 
nothing new, and is becoming popular to track major assets (eg in 

An Australian based RFID technology company, G2 Microsystems, 
develop IC for such devices.

CISCO and others incorporate RTLS technology in their access points.
