RuBee is often confused with RFID Radio Frequency Identification. It does not work like passive or active RFID, and has a protocol more in common with WiFi, Bluetooth 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 typically WiFi and Zigbee works in the VHF, UHF or SHF bands and with the electric field.

Comparison of RFID Vs RuBee Wireless Sensors Networks

  • All RFID tags are backscattered transponders. RuBee is an active transceiver.
  • RuBee is a bidirectional, on-demand, peer-to-peer, radiating, transceiver protocol operating at wavelengths below 450 Khz.
  • RuBee protocol works in harsh environments with networks of many thousands of tags and has an area range of 10 to 50 feet.
  • Cost – RuBee provides more functionality for a lower cost respective to an RFID tag with similar features.
  • Long Life – The RuBee tag runs at low speed because of the low frequencies it uses to transmit information. Batteries can last up to 15 years
  • Security – RuBee tags are far more secure than their RFID counterparts. The range at which one can intercept messages is about the same as the range of the tag itself. The tag can also implement further security measures such as keys and pads.
  • Safety – The RuBee system only emits nanowatts of radio energy. This means that RuBee produces about 10 times less power and field strengths than a metal detector.
  • RuBee unaffected by water, and steel can enhance signal or not affect
  • RuBee reads in a volume vs. RFID has reads in an “angled cone” – a flash light, beacon.
  • RuBee volume reads in harsh environment – RFID is Line of Site near steel or water
  • RuBee tags can be thin tag waterproof and military rugged
