Ad Hoc on the a Band

I am having trouble setting up an ad hoc network on the 802.11 a band.
Someone mentioned to me that this was not allowed by the 802.11
regulatory specification, but I have not been able to find that
information in my IEEE spec (perhaps because they are old).

If anybody knows about this, please respond.

thx,

Hi
It should work in Ad-Hoc Mode.

Thanks for the detail. It does clear up some of the issue.

What I have is an Atheros 5006 running on a WINCE 5.0 platform. I
updated the ar5210.reg file to have the device use the a band, channel
36 when an ad hoc network is created. This works fine and the sniffer
shows the CE device beaconing on channel 36. However, when I change the
channel to 52, things go wrong. The sniffer shows that the CE device
still beaconing on channel 36 instead of 52 (strange).

A coworker of mine suggested that this was probably due to regulatory
constraints and when setting the ad hoc band to a, it probably just
ignores the channel setting and defaults to 36 always.

I'd be interested to see if Vista allows you to set the specific channel
in the a band or if it too limits ad hoc on the a band to channel 36.
