Broadband over Powerlines - analytical review

A leading Australian internet research, analysis and strategies consultancy, Caslon Analytics Pty Ltd has reviewed the state of play with BPL and drawn a number of conclusions and makes several observations.

In its review, aimed at industry and the investment sector, Caslon Analytics finds that some observers have characterised BPL as a marketing phenomenon, and not a technology that will gain global acceptance.

The Canberra-based Caslon Analytics says the theoretical claims for BPL to provide every home with a fast internet connection have not been tested on a large scale in a commercial environment.

BPL industry media releases, it says, promote major benefits for consumers and power companies, but contain no substantive mention of technological or regulatory concerns.

A lack of balance is occurring with little or no reporting of criticism of BPL or the failures of the industry when commercial backers withdraw from projects.

Caslon Analytics refers to BPL in New Zealand as having followed the same trajectory as overseas, with initial hoopla, small-scale trials and little follow-up.

The trial in Auckland by United Networks and Vector ceased after it "failed to produce commercial results", with Vector commenting that "we haven't been able to get anything commercially viable ... We can't get enough distance and the equipment is a bit expensive".

The review is extensive, discusses the radio pollution concerns surrounding BPL, and can be read on the Internet (text version http://www.caslon.com.au/powerlinenote.htm)
