Introduction Principle How it works Block Diagram of Red Tacton Transceiver Working procedure Security Transmission modes Merits and Demerits Applications Conclusion

• Red Tacton is a new Human Area Network technology.

• It gives us safe and high speed network transmission.

• Developed by NTT, a Japanese Company.• Red Tacton uses weak electric fields on

the surface of the body as a transmission medium.

Transmitting transceiver creates a change in the field.

Some 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.

Requires physical contact.Must be wearing the transceiver and

touching something else with a transceiver.

The transmitting and receiving electrodes of the Red Tacton transceiver are completely covered with insulating film.

When communication occurs , displacement current is generated by the electrons in the body because the body is subjected to minute electrical fields.

1) Touch2) Broadband & Interactive 3) Any Media

Touching, gripping, sitting, walking, stepping and other human movements can be the triggers for unlocking or locking, starting or stopping equipment, or obtaining data.

• Duplex, interactive communication is possible at a maximum speed of 10Mbps. Because the transmission path is on the surface of the body, transmission speed does not deteriorate in congested areas where many people are communicating at the same time.

• Maximum communication speed may be slower than 10Mbps depending on the usage environment.

• In addition to the human body, various conductors and dielectrics can be used as transmission media.

• For example, metal or water could be used.

Data transfer is faster and easier through this technology.

Data loss during transfer is less.Use of minimum amount of power(of some

milli volt range)Security is more.

It has no compelling applications that aren’t already available.

Too costly.It can be useful within few centimeters

only.Not useful unless many people adopt it.

• I conclude by saying that Red Tacton is one of the best technologies ever when compared to all the other technologies in existence today.

• There is no trouble of hacking as we ourselves act as media.

• For short distances, Red Tacton is the best to connect to the network.

• If this excellent technology is brought into the market soon, it would bring tremendous change and would be adopted by many people all over the world.
