in terms of physical layer (layer 1) - TurboCell and 802.11b is basically
the same - both use DS, etc
TurboCell's difference comes in the MAC layer (layer 2) - mainly in the MAC
layer control mechanism
802.11b uses a MAC control mechanism as CSMA/CA - a rough analogy; modified
Ethernet CSMA/CD
KarlNet uses a MAC control mechansism of dynamic polling - a rough analogy;
token ring
When a few nodes are in a short-range environment, closely together (indoor
wLAN) - CSMA/CA is more efficient
In an outdoor WISP environment, where many nodes are spread throughout a
large radius - polling is a more efficient

At the lower levels the Turbo Cell protocol works similar to 802.11b ad-hoc
or point-to-point systems. Or at least it does not fuction as an AP and
send out 802.11b AP beacon messages. This may be part of the reason Karlnet
does not do Auto Fallback speeds with Turbo Cell.
I am under the impression it does the polling, NWID and "System Access Pass
Phrase" on top of that.
If this answer is confusing or wrong please ignore.
I also see this same issue when doing a link test on some customers.

Here is my setup
AP-1000 w/ ISP base
RG-1000's w/ SOHO
Why when I do a link test at a client why do I not only get the
access point but adjacent clients? If I choose an adjacent client it looks
as if the clients are actually communicating with each other. It is
something I see all the time and would really like to know why they come up
this way.
Thanks,
Bob Hrbek
