Re: [amsat-bb] 2.4 GHz wireless network interference to AO-40 station ??

["Greg D." <ko6th_greg@xxxxxxxxxxx>]

Hi Jeff,

I had the same worry, and was surprised to find that I couldn't even detect 
the presence of the Wi-Fi net.  If you use the upper channels (11 is best), 
you will be clear of AO-40's downlink.  But, as an experiment, I tried using 
channel 1, and still couldn't hear it.  In fact, my "DSL" service is from a 
wireless ISP, yes, on channel 1.  The Wi-Fi antenna is a 18 dbi patch with a 
built-in radio; it's aimed away from my AO-40 antenna, but even with a good 
front/back there's got to be a bunch of energy coming out of the rear.  But 
I can aim my AO-40 dish right at the patch, and the ISP's transmitter behind 
it, and don't hear a thing.  Can't explain why.

I suppose if you had a whole bunch of computers and APs all on channel 1, it 
would raise the noise floor enough to be a problem.  Put them on 11 and 
you'll be fine.  I've discussed that possibility with my ISP, and he's 
willing to make the change, if his service becomes a problem.

Now, if they could just kill those #!$%^#% cordless phones....
