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.

How it works

How it Works?


Redtacton

The electric field Es that reaches the receiver is

Es = Ea – (Eb + Ec)


Redtacton

  • 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.

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.
