High frequency radios are still recommended for people travelling in remote areas. When tourists and 4WD enthusiasts are planning outback trips they should contact a Flying Doctor Base to ensure they are equipped with the appropriate communications equipment and information.
There is already significant evidence from overseas trials that the technology involved in BPL impacts heavily on this area of the radio frequency spectrum but this is conveniently overlooked by the companies seeking to introduce this technology. The necessity for this technology is questionable particularly in light of the fact that broadband or other high speed
services are deliverable by many other means in remote areas such as satellite and ISDN telephone lines.
There are so many users of HF who aren't going to be able to afford the changeover to alternative technologies this is definately not a good idea in a country with such distances to communicate over.
Why would I want the ongoing costs of satphones when I can use my HF for next to nix?
Have a look around the net and on the Australian Communication's Authority's web site and you might change your thinking (Solarpanel & Groove)
BPL is not the panacea that it is cracked up to be.
The Australian Communications Authority Background Briefing into BPL technology states that,
“HF communications is particularly important in Australia for long distance communications, and some of these
services have defence or safety-of-life implications.” (Page 9, Download Report
)
It goes on to state that:
“There would appear to be a potential risk to HF radiocommunications
services from the widespread use of broadband powerline communications systems; the risks appear to be associated with in-house applications as
well as last-mile applications. This can be seen in the early filings to the FCC enquiry into powerline communications and the findings in ECC Report 24. There have now been broadband powerline communication trials held in the USA, Europe and Asia. The results of these trials have not alleviated concerns over the potential interference risk to radiocommunications.” (Page 16)
The ACA recognises also that conditions which allowed BPL in other countries may make BPL technology dangerous in Australia:
“Europe and the USA have greater degrees of urbanisation than Australia
and the weighting placed on the protection of HF
services in those countries may
well be less than that required in Australia.” (Page 16)
Technology isn't always good progress, and those that seek to introduce it are often induced by $ potential, not the good of the community.
Before Solarpanel & Groove stick the boots in:
I do live in a rural community. I do own a HF. I don't want a satphone as it won't do what I want and it won't do it at ten times the cost or more. I have seen HF save lives in the past six months.
If it was your kid's life at stake in the Wonnangatta would you want my
HF radio, my skills (Paramedic) and my
first aid kit and a helicopter to get your kid to hospital? Or a band aid and a wave because that's as much as I can do without comms.
Your call,
