The success of G is less noise and less power. IMHO
Never looked for a G amp or tried a G high powered card.

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

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.

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

I use pretty much all rootennas these days
5gig, 2 gig, and even 900 now.
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
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
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.

I know this goes farther than the B versus G debate that was started,
but the key thing in being able to do this is the cloaking with its
reduced RF spectrum use. A B mode AP cannot do cloaking, nor can
your AP do it if the AP is not
