introduction
Introduction
  • Human Area Network………
  • Uses the surface of the human body.
  • Technically, it is completely distinct from wireless and infrared technologies.
  • RedTacton can achieve duplex communication over the human body at a maximum speed of 10 Mbps.
  • Transmission path is formed when a part of the human body comes in contact.
history
History
  • The concept of intra-body communication was first proposed by IBM in 1996.

Reported technologies had two limitations 

    • The operating range through the body was limited to a few tens of centimeters.
    • The top communication speed was only 40 bit/s!!

These limitations were overcome by NTT (Nippon Telegraph and Telephone Corporation) located in Tokyo, Japan by using photonic electric field sensors and finally in 2005 they came up with a human area networking technology called ‘REDTACTON’.

what is redtacton
What is RedTacton?
  • RED: a warm color emphasis and cordial communications
  • TACTON: Action triggered by Touching.
  • RedTacton utilizes a point to point network, known as a Pico net.

Transmitter sends data.
  • Transmitting transceiver creates a change in the field.
  • Field from human body dissipates into earth.
  • Electric field is received using sensing technology.
  • Receiving transceiver recognizes the change in the electric field.
  • Sensing technology measures the weak electric fields induced.
  • Electro-optical crystal uses laser to convert and read the signal.

Broadband & Interactive:

Bandwidth does not deteriorate even with duplex

operation & simultaneous access by many users!

challenges
CHALLENGES
  • The obvious barrier to entry is that the cost and time to develop HAN TECH. is very expensive.
  •  As a new technology HAN need to gain popularity among users to help pull the technology into the marketplace instead of having it pushed upon them. 
  • Widespread marketing campaigns will need to be developed to highlight the benefits of HAN technology to facilitate its adoption. 
  • Not useful unless many people adopt it.
  • It can be useful within few centimeters only.
