Abstract: Nowadays, due to enhancement in various networking
technologies the human expectations have raised to a very higher level. We
humans have adorned our bodies with all the latest networking gadgets around
us. So, the need for smaller devices with low prices for transmitting
information is increasing. The various types of connectivity options available
include LAN (Local Area Network), WAN (Wide Area Network), MAN (Metropolitan
Area Network). Now as human society is entering an era of modern computing,
connectivity should become very easy and handy where there is no requirement of
methods mentioned earlier. Redtacton comes up with a very challenging technology
that can transmit information and data through humans at high speeds where
there is no compromise with data security. Basically, Redtacton is Human Area
Networking technology.
Introduction: Redtacton, Human Area Networking technology was
introduced by Nippon Telegraph and Telephone Corporation (NTT) that uses the
human body surface as a high speed and safe network transmission path.
Redtacton is the electronic future where information can be shared whenever and
where ever required. All this can be done just
by using our finger tips with some equipment incorporated into our attire. We
can share data through different gestures. Like for example by just looking at
our wristwatch we can share our location. All this is possible with HAN.
RedTacton is a breakthrough technology that enables reliable high-speed HAN for
the first time. In the past, infrared communications (IrDA), Bluetooth, radio
frequency ID systems (RFID) and other technologies have been proposed to solve
the "last meter" connectivity problem. However, those technologies
each have various certain fundamental technical limitations that constrain
their usage, such as the precipitous fall-off in transmission speed and network
congestion in multi-user environment.
What this technology is? RedTacton Technology was
introduced by Nippon Telegraph and Telephone Corporation (NTT). TACTON - meaning
“action triggered by touching” and RED - It is an auspicious colour according
to Japanese culture for warmth. It is a technology that uses the surface of the
human body as a safe, high speed network transmission.
A brief study of Human
Area Networking-
a. RedTacton uses the minute
electric field emitted on the surface of the human body. It is completely distinct
from wireless and infrared.
b. A transmission path is formed at a part of the human body
which comes in contact with a RedTacton transceiver. Physically separating ends
the contact and thus ends communication.
c. Using RedTacton, communication starts when terminals carried
by the user are linked in several combinations according to the user's natural,
physical movements.
d. Communication is possible using any body surfaces, such as
the hands, fingers, feet, face, legs, skin or torso. RedTacton works through
shoes and clothing as well.
Features: RedTacton Technology has three main functional features:
a. Touch: Touching, sitting, walking, stepping, gripping and
other human movements can be the used as triggers for unlocking or locking,
starting or stopping the equipment, or obtaining data.
b. Broadband & Interactive: Bandwidth does not deteriorate
even with duplex operations and also simultaneous access by many users. Duplex,
interactive communication is possible at a maximum speed of 10Mbps. This is
because the transmission path is on the surface of the body; transmission speed
of RedTacton does not deteriorate in congested areas where many people can
communicate at the same time.
c. Any media: In addition to the human body, there are various
conductors and dielectrics can also be used as transmission media. Conductors
and dielectrics may also be used in combination.
Working: RedTacton takes a different technical approach. Instead of
depending on electromagnetic waves or light waves to carry data. RedTacton uses
weak electric fields on the surface of the body as a transmission medium as
shown in figure above.
a.
The Redtacton transmitter induces a weak electric field on the
body surface.
b.
The receiver senses the change in weak electric field on the
body surface.
c.
Redtacton relies on the properties of an electro-optic
crystal can vary according to the changes of a weak electric field.
d.
The figure shows a block diagram of RedTacton working.
Conclusion: We can conclude that Redtacton when compared with
other technologies can give a much better performance over others. And also we
can add it up by saying that when it comes to short distance network Redtacton
is the best way to do it. Also a major problem of hacking is solved as we use
our own body as a networking medium.
