Dude, there's interference everywhere in the 900 band. Cordless phones,
baby monitors, security systems, smart meters, SCADA.. and the list goes on.

If you do 6 sectors, you're using the entire band and have nowhere to
go when one or two sectors is experiencing interference. Or you have
to drop down to 5MHz channel bandwidth which sucks. This is why we do
4x90 clusters. Two channels with wiggle room. Of course that's FSK's
8MHz channel width. I think a lot of people have found that 7MHz on
the 450i works best.

No, I’m not complaining, I’ll use them. I’ll figure out how to

a typical tower. I have some learnin’ to do.

Well, if you want small... there's these, I'm not sure I'd want to
try doing channel re-use with them though.

I’m specifically interested in the 900Mhz, I thought that was the
450i, I didn’t know it covered 5.8GHz also. I also need maximum
bandwidth off the tower although I don’t know tower or other
mounting locations yet to determine if I need 360 degrees. I
actually have more problems with aesthetics and those antennas are
going to be an issue due to the size. Right now I’m interested in
throughput per antenna and what kind of throughput to expect with GPS.

If you guys are talking about the 900mhz 450i 65 degree. Straight
from the horse’s mouth is the 65 and the 90 are the same antenna.
Just more role off to achieve the 90. I have tested it outside of
the 65 degree but within the 90. I was not happy with the results.
One customer had to be put back onto FSK yesterday until we can
get another AP up or a true 90 degree. Just would not modulate up
and finally dropped off completely.

I looked at the 450i and noticed the sector antenna is 65 degrees.
Does that mean a typical tower installation uses 6 antennas? In
that scenario, I’m assuming 10MHz channels if there is no
interference. In that scenario, what is the available bandwidth
per AP assuming most users get pretty good signal. Or is there a
better way to deploy the product?
