RedTacton is a new Human Area networking technology that uses the surface of the human body as a safe, high speed network transmission path at a speed of 10mbps. RedTacton uses the minute electric fields generated by human body as medium for transmitting the data. It was developed by Japanese Technology NTT Lab.
NTT , the Japanese telecoms group, and the team of scientists invented the RedTacton system. "Tacton" because with this technology, communication starts by touching (Touch), leading to various actions (Act on). As reported on Gizmodo(02/25/2008), the technology is currently being marketed as a way to turn a human into a swipe card.
Three levels of connectivity:1.Wide Area Networks (WAN)- typically via the Internet.2. Local Area Networks (LAN)-typically via Ethernet or Wi-Fi connectivity.3.Human Area Networks (HAN)- for connectivity to personal information, media and communication appliances.
For communication terminals should be carried by the user or embedded in devices. It is a Duplex communication. RedTacton uses “SUPER SENSETIVE PHOTONIC” electric field sensor. The body surfaces may be any of our parts like hands,fingers,arms,face,feet,legs.
NTT has made three types of protocols:1)Redtacton Transceiver (PC card type)2) Redtacton Transceiver (Hub type)3) Redtacton Device (Box type)
Military Applications-to provide gun security. Medical Applications-medicine containers could have chips embedded in them that when touched could send an alarm to the user. Consumer Applications-such as admissions systems and payment processing devices.
Secure lock administration is possible by combining personal verification tools such as fingerprint ID biometric in the mobile terminal. Red Tacton can carry music or video between headsets, mobile devices, mobile phones. A communication environment can be created easily and at low-cost Communication.
It’s adoption could be slow since Bluetooth and other radio technologies are already entrenched. It will be comparatively expensive. As it uses electric fields on the surface of the body ,it may cause harm to the body.
We conclude that, when we compare RedTacton with other technology present today it can give a better performance over others and to connect the network with in short distances RedTacton is best. In this technology there is no problem of hackers as our body is itself a media Human society is entering an era of ubiquitous computing,
