ABSTRACT
Does the idea of using your body as a data transmission appeal to u? Then this paper will surely grab your attention. Technology is making many things easier; I can say that our concept is standing example for that. So far we have seen LAN MAN,WAN, INTERNET & many more here is new concept of “ RED TACTON ” which makes the human body as a communication network by name . HAN (Human Area Network). Focusing on the naturalness ,inevitability and sense of security conveyed by touching which we call Redtacton [Red-Warmth ,T-Touch ,Acton-Action]which could let people transfer data to each others handhelds by means of handshake or a slap on the back. using a transmitter embedded in say , a PDA Redtacton sends a 5 volts pulse along the surface of body. The human body shunts most of electricity to ground resulting in weak electric field that can be modulated to carry signals .As the receiver is located either on another part of the body ,the components of a hand free handset or in an acquaintance PDA as it senses modulation in the electric field the receiver decodes them to recover the data, Human Area Network is an important over current wireless technologies such as Bluetooth because users can narrowly limit signal recipients rather than broadcasting to all devices within given range. Using Redtacton enable devices music from our digital audio player in your pocket would pass through your clothing and shoot over your body to headphones in your years. Instead of fiddling around with the cable to connect your digital camera to your computer you could transfer pictures just by touching the PC while the camera is around your neck and since data can pass from one body to another you could also exchange electronics business cards by shaking hands, trade music files by dancing cheek to cheek or swap phone numbers just by kissing. While a good idea, Redtacton unfortunately has no compelling applications that are not already available. It doesn’t work reliably and yet has also been experiencing face perception among the general public. In this paper we will discuss about Redtacton and its working states and application of Redtacton in various fields and we will our Redtacton with other technologies for Data Transmission and know about Human Area Network.
INTRODUCTION
Today people can communicate anytime, anywhere, and with anyone over a cellular phone network. Moreover, the Internet lets people download immense quantities of data from remotely located servers to their home computers. Essentially, these two technologies enable communications between terminals located at a distance from each other. Meanwhile, all kinds of electronic devices including personal digital assistants (PDAs), pocket video games, and digital cameras are becoming smaller, so people can carry around or even wear various personal information and communication appliances during their everyday activities. However, user-friendly ubiquitous services involve more between remotely located terminals. Communication between electronic devices on the human body
(wearable computers) and ones embedded in our everyday environments such as illustrated in Fig. 1 is also critical, so this has driven extensive research and reported by several research groups around the development on human area networks. Wired connections between electronic devices in human area networks are cumbersome and can easily become entangled. Short-range wireless communication systems such as Bluetooth and wireless local area networks have some problems. Throughput is reduced by packet collisions in crowded spaces such as meeting rooms and auditoriums filled with people and communication is not secure because signals can be intercepted. The principle drawback of infrared communications (IrDA) is the tight directionality of beams between terminals needed for the system to be effective. The ultimate human area network solution to all these constraints of conventional technologies is “intrabody” communication, in which the human body serves as the transmission medium. In ubiquitous services (which imply communication between electronic devices embedded in the environment in close proximity to people), if we could use the human body itself as a transmission medium, then this would be an ideal way of implementing human area networks because it would solve at a stroke all the problems reduction, low security, and high network setup costs. The concept of including throughput intrabody communication, which uses the minute electric field propagated by the human body to transmit information, was first proposed by IBM.The communication mechanism has subsequently been evaluated and world. However, all those reported technologies had two limitations:
1) The operating range through the centimeters body was limited to a few tens of and
2) The top communication speed was only 40 kbit/s. These limitations arise from the use of an electrical sensor for the receiver. An electrical sensor requires two lines (a signal line and a ground line), whereas in intrabody communication there is essentially only one signal line, i.e., the body itself, which leads to an unbalanced transmission line, so the signal is not transmitted correctly.

APPLICATIONS
In this section we highlight three distinctive features of RedTacton. First, a transmission path is formed automatically by body contact and this initiates communication between electronic devices. A device can be started, information can be obtained, or various services can be triggered by a wide range of natural human actions such as grasping, sitting down, walking, or standing in a particular place. Second, the communication is interactive and broadband. In contrast
