RedTacton - Human Area Network Technology<br />
3.3 COMPARISON WITH OTHER NETWORK TECHNOLOGIES<br />
Performance:<br />
E: Excellent,<br />
P: Poor<br />
3.4 ADVANTAGE OVER BLUETOOTH<br />
The system envisioned by NTT, utilizes a conversion method which takes<br />
digital d<strong>at</strong>a into a stream of low-power digital pulses. These can be easily transmitted<br />
and read back through the human electric field.<br />
While it is true th<strong>at</strong> similar personal area networks are already accessible by<br />
using radio-based technologies like Wi-Fi or Bluetooth, this new wireless technology<br />
claims to be able to send d<strong>at</strong>a over the human skin surface <strong>at</strong> transfer speeds of up to<br />
10Mbps, or better than a broadband T1 connection. Receiving d<strong>at</strong>a in such a system is<br />
more complic<strong>at</strong>ed because the strength of the pulses sent through the electric field is<br />
so low.<br />

Tacton<br />
RedTacton solves this issue by utilizing a technique called electric field<br />
photonics: A laser is passed though an electro-optic crystal, which deflects light<br />
