Forgive my ignorance, but is this 'cloaking' you speak of, a feature of

I believe I said we use reduced X2 cloaking for reduced RF spectrum
usage, which you do not use because you have older gear or software
that does not support it. You even agreed that reduced bandwidth
works
e switching out our amps to three sector solutions when the customer
volumes go high enough.

We run as many as 4 G mode with 16 dB 60 degree sectors. The AP uses
WLM54SuperG Atheros radios with X2 cloaking so this means the 4
channels are not overlapping. We are in a valley and the AP sites are
typically on the sides,
vs the other.

Totally agree. A bad G link will still give as good as a GOOD B link.
G will give 5 mbps even when it is close to not connecting and B
requires superb signals to get 5 mbps.

There is nothing wrong with an omni if the users are all around it.
You get better signals with a sector but a microcell is the perfect
place for an omni. The fact that your current sites can see each
other is awesome and you are part way to achieving a Mesh.

Actually G mode works better than that. We have clients with -80 dB
and they can pull a steady 10 mbps on a X2 cloaked channel (10 MHz of
RF bandwidth). Even at -85 dB they can still pull 5 mbps and burst to
10 mbps.
Of course these results are with Atheros cards. I have no idea about

I use pretty much all rootennas these days

There is times when I may still need a grid, It just does not happen
very often. I've got a bunch of them I just took down and I still would
rather spend the money and use a rootenna type antenna.
The way I figure it is
I have quite abit of G out there. All the clients and ap's I install
today are G.
60's is great, 70's work just fine too.
60's get top performance, 70' is still a great very fast connection and
even low 80's beat B.
B stands for Bad
G stands for Good

It's not about antenna size. It's about signal levels.
Most g radios need -60ish signal levels to work well. Use the antennas that
you need to make it work right.
Find the sensitivity levels of the product you are using, run the calcs, and
compute a 10 dB or so fade margin.
