the Class Licence for spread spectrum devices, which is the same licence
that 802.11b operates under specifies a band at 5.8 GHz with 1W EIRP. There
are no restrictions that I can see here. This document can be found at
HYPERLINK
"http://www.aca.gov.au/legal/licence/class/spread.htm"http://www.aca.gov.au/
legal/licence/class/spread.htm
There is also the class licence for "Low Interference Potential Devices",
which lists the "other" 5 GHz band as indoor use only and 200 mW EIRP (with
technical conditions).
HYPERLINK
"http://www.aca.gov.au/legal/licence/class/lipd.rtf"http://www.aca.gov.au/le
gal/licence/class/lipd.rtf
I believe the problem is that most 802.11a gear currently available uses the
"indoor only" 5.2 GHz band. Gear using 5.8 GHz _can_ be used indoors and
outdoors with 1W EIRP under the same licence as 2.4 GHz uses.
I have added some excerpts of the relevant sections below. Refer to the
URLs above for complete information.

Subject: [MLB-WIRELESS] Need details on 802.11a outdoors...
I've been talking to a number of members of parliament about Melbourne
Wireless Inc and general 802.11 laws etc, and the matter of using 802.11a
outdoors was raised... I informed the member in question that 802.11a was
illegal to use outdoors under the current rules... We had a quick discussion
why this was so, and I've been asked to write up a quick report on why
802.11a should be allowed to be used outdoors, and what the exact details
are....
I'm kinda pushed for time at the moment, so I was wondering if I could get
you guys to find some details for me....
1) What is the frequency range of 802.11a equipment?
2) What is the allowed 5Ghz frequency range for outdoors?
3) What is around the 802.11a frequency range?
4) What is the ACA regulation showing this? (Act & section number or URL
would help)
Please reply to the list, as I'm going to formulate my response based on
everyone's input...
Thanks in advance - hopefully we can get 802.11a approved for outdoors use!
:)

Steven Haigh
