Hi, before this discussion thread gets too far out on a tangent ...
For the community solution, I'm assuming:
- all WAPs and bridges using same SSID, in an area with very few
other 2.4GHz devices around - they do exist ... ;-)
- the NOC - will be using directional antennas on non-overlapping
channels. I was going to use the 30 degree antennas
around the perimeter of the NOC building (ie. on the
outside walls, not from a tower on the roof), which
would likely mean the antennas shouldn't be interfering
with each other as the signals wouldn't likely penetrate
through the exterior and interior concrete walls very
far. But yes, the configuration would depend on the
building and doing a proper 'site survey'. So I may
need to reduce the APPO count for some NOCs.
- the remote site - would be located a mile (+/-) away and would
support local 'clients' and have a link back to the NOC.
- multiple RemoteSites would be installed in a trigular pattern to
blanket the area.
- clients could be - laptops, PDAs, tablets with a WiFi PCCard
- WiFi-capable cell phones
- desktop PCs, home networks, business networks
with WiFi device (card, USB bridge, etc.) of
some sort.
- bandwidth for any one subscriber connection (ie. at the MAC level)
would be limited by definitions within the subscriber's account
and would be enforced by a server in the NOC. So I don't care if
they run a whole corporation of PCs through that link - they're
only going to get a certain amount of bandwidth. They can certainly
purchase more bandwidth ... :-)
- roaming would be supported by a server in the NOC.
Thanks,
Steve

recommended for covering a small community ?
This is a good exchange ... Sully suggests a maximum of 60 clients per APPO.
Let me see if I can define 'client' so we can get a little further into this
question.
A 'client' is a client device associated with a household of three computers
that could be running at the same time. These two computers are running a
web browser, exchanging e-mail and instant messaging. The third computer is
generating a higher workload of some sort: gaming, file sharing or web based
music. This might be a good set of assumptions for this 'small community'.
Will one APPO really handle this kind of workload?

My quick 2 cents.
Unless you have some serious PHYSICAL separation from one side of that
building to the other, you will have BAD frequency interference.
Assumptions:
1. No one else is using 2.4Ghz band within MILES of your building
2. You plan on using channels 1, 6, and 11 (only non-overlapping
channels)
3. You plan to reuse channels 1, 6, and 11 for both vertical and
horizontal
The above shows that the max you could put off of one building would be
6 radios.
Radios support up to 128 simultaneous connections...but no one is going
to recommend that you put anything beyond 60 on each.
Therefore, you have 6 radios times 60 clients = 360 total clients off of
one WiPoP.
The other option would be to run all these radios on the same SSID and
allow for roaming. But that would be setting up a community hotspot.
Not my forte.
Again...that is just my personal opinion.
Sully

Subject: [smartBridges] Max clients per APPO ? SmartBridge recommended

Hi all, while I'm new to this list, I did try going thru the archives to
find an answer for this, but finally gave up looking for the proverbial
needle in the haystack.
I see in the specs for the AirBridge, there is a limit of 64 client IPs
-
but the same spec is not documented for the AirPoint.
Q1. How many concurrent mobile WiFi clients can be supported by the
AirPointPro Outdoor ?
Q2. Also, would you recommend this product line to provide WiFi coverage
for
a small community ?
I'm expecting to create a central site (or network operations center,
NOC)
which has:
- up to 12 AirPoint Total (each one covering 30' of the circle around
the
building),
- a server capable of supporting roaming, optional IPSEC links, RADIUS
accounting,
- a server for managing subscriber accounts which integrates with the
above
server,
- misc. servers for DNS, DHCP, firewall, etc.
- back-end high-speed Internet connection.
The NOC would support multiple 'Remote Sites', each with
- an AirBridgeTotal that points towards the NOC
- an AirPointPro with an omni antenna
Q3. There may be times when the NOC is not LOS with the Remote Site - is
there any reason why it could not instead be pointed to a nearby
RemoteSite
which would act as a hoping point ?
Thanks,
Steve.
