History Of HANistory Of HAN The concept of intra-body communication was

first proposed by IBM.

This communication mechanism was later

evaluated and reported by several researchgroups around the world.

All those reported technologies had two

limitations.

These limitations were overcome by NTT (NipponThese limitations were overcome by NTT (Nippon

Telegraph and Telephone Corporation) by usingTelegraph and Telephone Corporation) by usingphotonic electric field sensorsphotonic electric field sensors and finally came up withand finally came up with

a human area networking technology called a human area networking technology called REDRED

Human Area Networking is a technology that

safely turns the surface of the human body intoa data transmission path at speeds up to 10Mbps between any two points on the body.
