Power
Trunk delivers a 100 Mb/s on-premise data networking solution to enable
on-premise networks without the addition of new wires. Using the
Company's Harmonic Multi-Tone Spread Spectrum (HMT-SS) chip-set users
can use existing electrical power outlets and/or telephone outlets to
connect audio and video equipment as well as computer networks to the
Internet via cablemodems or xDSL modems. Most recently in Germany with an access system (transformer to the home). This system supported voice and data transmission at about 500 - 1000 Kb/s. |
