Taming the Australian Airwaves

It’s time to add another item to the survival provisions of those traveling
to the remotest regions of the continent of Australia. Along with the anti-snake
venom kit, shark repellant and English-to-Aboriginal Dictionary, intrepid travelers
would do well to pack their laptops and 802.11 access gear.

While much of the land down under remains untamed, a grassroots movement among
computer enthusiasts is steadily blanketing the Australian continent with networks
based on Wi-Fi technology. From Melbourne, to Perth, to even tiny and isolated
Tasmania, wireless networks offering both Internet access and high-speed links
to private networks have become the biggest thing to hit the Outback since CBS
wrapped up its Survivor series.

Providing some of the logistical work for coordinating the growth of community-based
wireless networks is Xnet Wireless, an Australia-based
business that maintains a Web site that provides resources for building wireless
networks and links to existing Wi-Fi hotspots across the continent. Xnet’s proprietor,
Paul Young, says that the tutorials and links on the site are an add-on to the
companies wireless hardware business.

"We provide the free services in order to grow the wireless market and
create interest in out products," says Young, who was interviewed through
e-mail exchanges with 802.11 Planet.

Young says that most of the participants in community wireless networks have
so far been hobbyists and technicians who have capitalized on the low-cost of
wireless technology to string up a high-speed network to largely share files
and play games. Another perk of the wireless communities, says Young, is the
ability to share Internet access.

For Australians who live and work outside of major cities, Young says broadband
Internet access is difficult to find.

"Australia seems to be lagging behind some other countries when it comes
to broadband Internet access," he says. "This is made worse by the
fact that it is a very large country with low population densities outside the
capital cities."

For the most part, Internet access doesn’t seem to be much more expensive than
access charges in the United States. Young says that a typical dial up line
is about $25 to $30 a month in US money for unlimited access. A broadband cable
connection, he says, runs about $65 a month, with a cap on what subscribers
can download.

In addition, Jean-Michel "Mick" Howland, who runs a seven-node Wi-Fi
network in Perth called innaloo.net, says
that Internet access providers charge extra for long distance and international
traffic. That’s the primary reason Howland does not plan to allow his wireless
network subscribers to share access to the Internet over his DSL line.

Fitting the pattern of most of the Wi-Fi networks that are springing up down
under, innaloo.net is primarily dedicated to high-speed exchanges among a group
of friends or colleagues. "Most of the people on the network work in the
IT field and rely a lot on the network for after-hours maintenance of systems
at work," says Howland. "So the value would be almost essential in
some ways."

Both Young and Howland, who was also interviewed via e-mail, cite the ease
of use and low-cost of using unlicensed wireless spectrum as the primary catalyst
for the surge in community-based wireless networks across Australia.

"I guess once again it all boils down to money," says Howland. "We
can link together friends at multi-megabit speeds for nothing. To do this using
normal telephone companies, such as Telstra, would cost us tens of thousands
of dollars per month."

Howland says that in 1999 he was paying about $2,500 Australian for a 2Mbps
connection to a point of presence (POP) in Perth, which is about 8 kilometers
from innaloo’s hub.

In Tasmania, an island about the size of West Virginia off the southern coast
of Australia, a group of wireless users have launched the Tasmanian Public Airwave Network (TPAN).
According to the organization’s FAQ, one of the major motivations is to help
IT workers defray some of the expense of downloading large files from the Internet.

According to the document, Internet access in isolated Tasmania is largely
based on a per-bit pricing scheme. Downloading the Linux kernel, for example,
could cost an Internet subscriber roughly $17, according to the TPAN site. By
hosting files frequently downloaded by small businesses on a wireless network
with no access charges, business could have high-speed access to vital information
without paying an arm and leg to download it from the Internet. (The operators
of the TPAN network did not return any e-mail inquiries.)

While the majority of community networks across Australia are not interconnected,
Young says that one of the functions of Xnet is to provide a sort of clearinghouse
for information that will help operators of individual networks forge peering
relationships. At this point, says Young, ISPs don’t seem to be concerned that
Wi-Fi hotspots that share Internet access are siphoning off significant revenue.

He says that the small amount of Internet sharing that goes on among members
of a Wi-Fi community has yet to capture the attentions of ISPs.

As these networks grow and become united, however, that situation could change.
