世論 What Japan Thinks

Oops, I forgot to post this last night!

A recent survey conducted by goo Research into computers was reported on by japan.internet.com, where they chose to focus on PLC-related questions. PLC is Power Line Communication, using existing electrical circuits as network cabling.

Demographics

Between the 13th and 16th of April 2010 1,088 members of the goo Research monitor group completed a private internet-based questionnaire. 52.3% of the sample were male, 16.1% in their teens, 17.9% in their twenties, 21.1% in their thirties, 16.2% in their forties, 16.5% in their fifties, and 12.1% aged sixty or older.

The total awareness from Q1 is 39.0%, yet last year it was 48.5%, and 51.7% two years ago. Similarly, the usage rate dropped from 2.8% to 1.4% over the space of the last year.

It’s supposed to be a good and cheap way to network and more secure than wireless, although interference when other electrical devices switch on and off is the biggest drawback.
