Human AreaNetworking (HAN) isa technology thatsafely turns thesurface of the humanbody into a datatransmission path atspeeds up to 10 Mbpsbetween any twopoints on the body.
HAN Technology, Transmitting data usingelectric field on the surfaceof the body
Communication ispossible using any bodysurfaces, such as thehands, fingers, arms, feet, face and legs.RedTacton worksthrough shoes andclothing as well.
A sensor that bouncesa laser beam off of acrystal (electro-opticcrystal) and measuresthe reflected beam.Oscillations in theelectric fieldsurrounding thecrystal affect thecrystal, which changesthe reflected lightspolarization
Transmitter induces a weak electric field on surfaceof the body. Receiver senses changes in the weak electric field onthe surface of the body caused by the transmitter. Optical properties of Electro-optic crystal varyaccording to the changes of a weak electric field. Changes in the optical properties of an electro-opticcrystal is measured using a laser and converts theresult to an electrical signal in a optical receiver circuit
Communication starts when terminals carried by the user orembedded in devices are linked in various combinations throughPHYSICAL CONTACT according to the human’s naturalmovements.
Duplex, interactive communication is possible at a maximumspeed of 10Mbps
Human body, various conductors and dielectricscan be used as transmission media.

The evolution of Red Tacton, technology is a bigachievement, which will likely be targeted for use in applicationssuch as wireless headset, medical application , securityapplications, wireless transmission by applying different actions. No Problem of Hackers Speed Enhancement for short distance Communication, of about10Mbps Uses Electro-optical effect(not electro-magnetic)
For long term plans the size of the transceiver should bereduced. Trident Method. High cost of Electo optic Crystal. Optical Pick Up Technology. NTT is committed to quickly identifying and openingup those application areas with the most commercialpromise for RedTacton , a business development process to becoordinated under NTT’s Comprehensive Product Functionprogram Efforts are already under way to improve HAN communicationmodules, including lower power consumption and thinner profiles. Telecom giant Nippon Telegraph and Telephone Corp (NTT) isplanning a commercial launch of a system to enter rooms thatfrees users from the trouble of rummaging in their pockets orhandbags for ID cards or keys.Touch-Tags Mobile can be automatically charged , while user iscommunicating.
