What is Redtacton..
“ A New Technology That Will Turn Human Body Into Communication Path “
3
3 Levels Of Connectivity
1. WAN – Re m o te l y C o n n e c t A l l Ty p e s O f S e r v e r s A n d Te r m i n a l s
2. LAN – Interconnects Computers Within A Limited Area Such As A Home school
3. HAN - F o r C o n n e c t i v i t y To Pe r s o n a l I n fo r m a t i o n , u s e s H u m a n B o d y

HAN- Human Area Networking
It uses the surface of the human body
It is completely distinct from wireless and infrared technologies
it uses the minute electric field emitted on the surface of the human body
History
First proposed by IBM
Operating range was limited
Speed was only 40 bit/s.

Overview Of Redtacton
• Introduced by NTT
• Innovative Human Area Networking Technology
• Uses Weak Electric Field On The Surface Of The Body
• Communication Is Possible Using Any Body Surface
• Transmission Path Is Formed When Human Body Comes In Contact
With A Redtacton Transceiver
• Uses Super Sensitive Photonic Electric Field Sensor
6
Meaning of Redtacton
• Red - Warmth,
• T - Touch,
• Acton - Action.

NARRATIONHow Redtacton Works
Transmitter induces a weak electric field on the surface of the body.
Receiver senses changes in the weak electric field.
The Optical Properties Of An Electro Optic Crystal Can Vary According To The
Changes Of A Weak Electric Field
Detects changes in the properties of an electro-optic crystal

Mechanism Of Redtacton
• Data is received using photonic electric field sensor.
10
Transfer Of Data
11
Redtacton Transceiver
• The Data Sense Circuit Senses The Signal• After Sensing ,Transmitter Circuit Activates• The Changes In The Electric Field Is Detected By The Sensor• The Output Will Be Given To Detector Circuit
12
Functional Features
A Communication Path Can Be Created With A Simple Touch,
Automatically Initiating The Flow Of Data
Two Way Communication Is Possible, point-to-point
Up to 10 Mbps Transfer Speed
Signal Can Travel Through Users Clothing, shoes etc.
Redtacton Utilize A Wide Range Of Materials As Transmission Medium
13
Set Up Of Intra Body Communication
14
System Safety
No Current Flows Into Human Body From Redtacton Devices
Naturally Occurring Electric Field Is Used For Communication
Devices Are Covered By Insulating Films
Satisfies Radio Frequency Exposure Protection Standard(rcr STD 38)
15
FEATURES OF REDTACTON
1. Touch
2.Broadband
3. Any media
16
1.Touch
Touching, Griping, Sitting, Walking and other human movements can
trigger the actions
17
2.Broadband
• Bandwidth is not at all affected with the variations in the number of users
• Not affected with the use of duplex operation.
• The speed is not compensated in congested areas.
• Communication possible at a maximum speed of 10Mbps

3.Anymedia
• Redtacton can utilize a wide range of materials as a transmission medium
• Conductors and dielectrics may also be used in combination.
20
Comparison With Other Human Communication Methods
• RedTacton does not require the electrode to be in direct contact with the skin.
• With the electric current method, electrode must be in direct contact with the skin.
21
APPLICATIONSMajor applications of redtacton
One to one services
Intuitive operations of personal information
Device personalization
New Behavior patterns
Marketing applications
Security Applications
22
Military applicationsA Redtacton transceiver can be implanted in the gun.
This can reduce the black market of the weapons
The misuse of stolen weapons can be reduced
23
Comparison With Other TechnologiesThe performance of is better as compared to other technologies as Wi-Fi, Bluetooth, IrDA
It is best to connect network within short distances.
There is no any type of problem of hackers as our body itself is the transmission media.

Advantages of Redtacton
• Data transfer is faster and easier through this technology.
• Data loss during transfer is less.
• Use of minimum amount of power (of some mille volt range).
• Security is more.
• Less Charging
26
• RedTacton does not require the electrode to be in direct contact with the skin.
• High-speed communication is possible between any two arbitrary points on the body.
• Body-based networking is more secure than other broadcast systems,
• Network congestion due to fall in transmission speed in multiuser environments is
avoided
• Superior than Infrared technology Superior than Wi-Fi.
Advantages of Redtacton
27
Disadvantages of Redtacton
It Can Be Useful Within Few Centimeters.
User Must Be Familiar To Technology For Efficient Use
It Has No Compelling Applications That Aren’t Already Available
It Is Very Costly.
28
Scope of Research
• Communication between electronic devices on the human body
• Wired connection can be replaced.
• Can be implemented to Avoid packet collision in crowded areas
