Yep. Very few people (less than 5%) who deploy dense wireless LANs
understand that the interference radius around each access point omni
antenna is 4 times to 8 times (or more) GREATER than the usable
communications radius. People end up putting too many access points too
close together result
I strongly suspect that Alvarion would not "blow this test out of the water"
because they, like Cisco and Aruba, do nothing (so far as I know) to
coordinate transmissions to mitigate self-interference. Meru does, and this
is why it comes out so far ahead.

This afternoon while I was at the shop I noticed the internet was very
sluggish. So I opened up an ssh session into the tower ap that is
serving my shop. It was saying 3,900 to 4,000 something kbps in the
interface. I was thinking for a second

This does not surprise me that they ran in to this. The 802.11b/g spec is
designed as a carrier sense collision avoidance network where all users are
within range of each other so they can be polite and not transmit over top
of another. When you have all sorts of users and multiple access points

There are a number of things to do to gauge the quality of a link with MT.
CCQ is one. Signal levels, as well as Ping tests will give you most of what
you wish.
All three put together will tell you. Also, a ping test over a period of
time is helpful as well.

The problem with stats is they often are displayed as total loss from the
beginning of time. Not specific to an exact period, of controled usage.

to measure it after the change nad before the next one.

Since Trango offers SNMP, could it be programmed to work with the MT?
We are using the Dude with our Trangos and that works very well.

If you want to do that with star and I'm sure mt and others have this as
well. You just simply open up the ping utility on the ap and ping the
client. You can select your packet sizes as well.
And another thing we do, is to test throughput from the su to the ap or
beyond with the built in bandwi

With Mikrotik, you have stats for the wireless link as well. You

Hi,
With a product like Trango, they have a utility called "linktest" that
shows packet loss after sending ten sets of 100 packets and measuring
on both sides the loss:
[suid] 2 [pkt len] 1600 bytes [# of pkts per cycle] 100 [cycle] 10
0 [AP Tx] 100 [AP Rx] 96 [AP RxErr] 0 [SU Tx] 100 [SU
It was a mistake.
Never have I seen Chuck do religious or political postings on any list.
Anyways, this is probably a reaction to Starbucks loosing market share
and probably some long term negotiations on ATT's part.

Not weird really...just a discussion of a particular Christian doctrine.
Not sure how that applies to Starbucks though... :-)

I'm looking to expand my training on Mikrotik. As far as I know the two front
runners are Butch Evans and Mikrotik themselves. Mikrotik is cheaper than
Butch, but Butch seems to cover things more. Butch also has available an
advanced course.
Comments?
