rubee is often confused with radio frequency identification (rfid). it does not work like passive or active rfid, and has a protocol more in common with wifi and zigbee. all passive and active rfid protocols use what is known as backscattered transmission mode. passive and active rfid tags act like a mirror, and work as reflective transponders. in contrast rubee, similar to wifi and zigbee in that it is peer-to-peer, is a networked transceiver that actually transmits a data signal on demand, but is much slower (6-8 two way packets per second). the main difference between rubee and wifi or zigbee is that rubee works in the long wavelength band using the magnetic field, whereas wifi, bluetooth, delta7, and zigbee work in the vhf, uhf or shf bands and with the electric field. the 1902.1 standard has been approved by the ieee. rubee received the technology of the year award from frost & sullivan in 2007.
