  • 1. RED TACTON –DATA TRANSMISSION TECHNOLOGY BHARTI VIDYAPEETHS COLLEGE OF ENGINEERING, GSSIP UNIVERSITY,DELHIChetna rdeepali92@gmail.comInstrumentation and control(III YEAR) Instrumentation and control(III YEAR) ABSTRACT : body as a safe, high speed network transmission path. In an age where information is being considered as the blood of this century, the RedTacton takes a different technical very idea of transmitting such data or approach. Instead of relying on information to someone very specific sends electromagnetic waves or light waves to carry these cold waves all around our body. With so data, RedTacton uses weak electric fields on many hackers and other anti-social elements the surface of the body as a transmission spread all around the world, secure data medium. A RedTacton transmitter couples transmission is considered to be a myth these with extremely weak electric fields on the days. With the recent technological surface of the body. The weak electric fields advancements success has been achieved to an pass through the body to a RedTacton extent in tackling the above stated issue.
