[MLB-WIRELESS] Flogging a dead horse.

[Peter Buncle]

Evening,

I too would like a formal answer on this one.

I was actually reading an article in a recent WIA magazine which had
comment from the ACA on this issue.

The basic outcome as i read it, was that as a licenced amateure you are
allowed to run upto 100w. 
(i think thats tx power too , not eirp)
on 802.11b, but they encouraged amateurs to be mindfull of interference
where ever possible.

Cheers

Peter

Hello,

I just thought I would do a bit of regulatory research into power usage
of 
wlan e
quipment an the amateur radio operator.

I visited the ACA web site (www.aca.gov.au) and found the Technical
Licence 
Specification
(TLS) that governs the various levels of licences for amateur radio 
operation in Australia.
This TLS stated what power levels are allowed for what spectrum
allocation 
and any restrictions
  thereof.

Reading through Schedule 2 part 5 shows me that within the amateur 
allocation 2400.000 Mhz
to 2450.000 MHz Unrestricted and Limited licence level holders are
allowed 
to utilise ANY mode
of operation with the exception of areas of the 3.4 to 3.6 GHz band.

Further reading,
Part 3
(16)
(1)

Subject to section 15, the licensee must not operate an amateur
unrestricted
station, using a transmitter output power of more that 400 watts pX, it
the
emission mode of the station includes:

(a) C3F;or
(b) J3E;or
(c) R3E


(2)

The licensee must not operate an amateur unrestricted station, with an 
emission
mode mot mentioned in subsection (1), using a transmitter output power
of more
than 120 watts pY.

Subsection (15) gives frequency allocation restrictions for the 50 MHz
band 
and the
3 Ghz band

Emission types, C3F, J3E, R3E represent........

C3E = AM or VSB Analog modulated Telephony

J3E = Suppressed Carrier Analog Modulated Telephony

R3E = Reduced Carrier Analog modulated Telephony

So,  if one was to interpret this literally,  being allowed ANY emission

type in the
2.4 Ghz section would mean that one, suitably licensed, could indeed use
upto
120 watts carrier power using DSSS emission type.

Now.  I could NOT find any reference to Amateur Radio DSSS emissions on
the
ACA web site?

Can anybody quote me a document that either shows that DSSS is a
restricted
emission type for amateur radio or other relevant information that will
lay 
to rest
my interpretation of the regulations pertaining to amateur radio
operation.

Before anyone jumps on my back about HIGH power WLAN usage.  I am not
thinking about a 120 Watt Node or anything like that, however I would
like 
to know
that as a licenced amateur radio operator, if I was to pump a higher
level 
of RF
into an antenna, (up to 10 watts say), that I was being legal within the

regulations that
I am licensed under.

No Flames please

Mark
