As soon as you can offer 7ms latency to 100 people off the same AP
using WiFi based radios, please let me know. I will buy 200 AP's and
5,000 CPE. ;)
Oh, and they need to operate on the same channels within a 5 mile
radius. ;)

I, too, thought it was impossible. We started with Orinoco back in the day
(2002), it worked well up until 30 subs -- then it was like dailup. Back
then, we offered 256Kbps service. Turns out the big differences is not only
much better radios, much better software, but also the difference on B and
G.
For a very long time we got caught in the Canopy mentality "my Canopy is
better than your <<any other vendor here>>" We finally opened our eyes, got
jumped out of the gang, and are very happy we did. It seems a lot of Canopy
operators have the mentality that WiFi sucks -- probably because they too
started with it years ago, when it really did suck.
Canopy is good, but slow, and very expensive. We have a 1 Day ROI.
Compared to when we were deploying Canopy, 8-10 MONTHS.
This network is small, and we don't push it much. Like I said, we have a 1
Day ROI.

You don't say if you are using 5Mhz or 10MHz channels. I assume 10
with 40 customers.
With the smaller bandwidth and slower speeds I think fractional
channels limit the number of subscribers you can put on an AP. Does
anybody have any empirical data on the number of users that can use a
5MHz and 10MHz Ap?
I am not doing it, but think 40 is too many for a 5MHz channel, and
has to be approaching the limit for a 10MHz channel. Thoughts?

very small. We mainly focus on big businesses.

How many users per AP?

Our 2.4GHz spectrum is completely filled with vertical Canopy.
We run UBNT AP's. Fixed at 2mi ACK. No RTS. Fixed G-only.
Horizontal
polarity. Max data rate of 54Mbps. Sectors.
Customers are all within 2 miles, use Loco2's. Customers are Auto
ACK.
No
RTS. Fixed G-Only. Horizontal. Max 54Mbps.
On almost every single install we get at least 12Mbps down, 6Mbps up
(our
rate limit). Without limit, we usually see up to 18.
Funny... those lusers on the other guys Canopy pay like $40/mo for
1.5Mbps.
We give 12Mbps for $24.95/mo.
Don't use B. It's DSSS. G is OFDM. Performs much better.

In 2.4 land, if you have a lot of noise, which protocol is better -
B or
G?
Is it better to run an AP as locked into one mode or is it OK to do
a
mix?
Max I want off of 2.4 customers is 3meg so not that worried about
the
extra
speed that G will provide, but, I would like to know which is more
stable?
I've always thought that B was more stable overall but just provided
less
bandwidth. I've gotten some info that may counter that. What's the
real-world experience with folks in a high-noise environment,
combined
with
a higher useage AP?
I've got an AP that we've run in B mode only for a while. We've
started
having problems with it - speeds go from 3meg at the customer to
200k
and
fluctuate constantly. We've worked with RTS, ACK timeouts, etc etc
and
nothing seems to have improved the stability. For testing purposes
we
put
up another AP right next to the one we're having trouble with.
Switched
two
of our gaming clients to that one (setup as G mode only) and they
seem
to
be
doing better, but not quite as good as we feel they could be. This
is
on
Deliberant AP's (Duos). The backhaul part of it is not the issue -
we
can
pull close to 15meg back to our office when cabled into the AP. We
have
other Deliberant APs that are running MANY more clients than this
one so
we
know it's not limitations of the equipment. AP is on top of a water
tower.
Have taken all clients off and brought them back on one by one and
it
did
not reveal anything significant. With just one customer on the AP
started
acting up again. Swapped radios in the AP thinking we could have
one
going
bad and still no luck.
2.4 antennas are H-pol. We have a ton of noise in the area, but
we've
been
through basically every channel and it did not help either. Other
AP's
in
the vicinity are performing fine. Thought of the multipath issue so
we
raised our test AP up a little higher than the other one. As I
said,
the
test AP seems to be better, but next to it on top of the tower we
can
get
around 8 or 9 meg down (locked into G mode), but at the CPE's we're
still
barely getting 2.5-2.8meg.
Any thoughts? We changed everything we can. The new "test" AP has
a
9db
antenna compared to the 13db on the "production" AP. Other than
that,
they
are identical as far as equipment goes.
So, back to the subject question though, what's real-world
experience
with
G-only mode in the field?
