Real-world conditions almost always seem to shoot lab conditions in thefoot. I think Tom's has done a follow-up recently that show some of thestrengths and weaknesses of a wide variety of APs.

I think the beam-forming concept used by Ruckus is very interesting aswell as very effective.

We’re looking seriously at Ruckus to solve our coverage issues
simply due to the fact of where we had to install our APs in
our dorms (in the hallways). Our initial tests show much
improved SNR over most vendors to the edge of our dorms with
their mid-range AP. We had another vendor test almost as
good; Aruba (G SNR was a good bit lower but still above 30 in
most places, but A was a little higher on average). These
tests were in a pristine wireless environment; no sacks of
water, books, etc… A lot of the performance difference on the
omni antennas, which all use except Ruckus, has to do with the
gain and thus the horizontal push from the antenna in our
environment. We aren’t looking to decrease our AP count.

Excellent information, Harry- Thanks. I have a feeling Cisco
cringes to read that 3500 APs were tested with 4402s instead
of 5508 controllers.

Yes, we ran both systems at max power to allow for greatest
range; our densities in some lecture halls were over 150
active users for one array.

Ruckus provides a link to Tom's Hardware Guide that has done
some extensive testing of several front-line enterprises APs.
The results may surprise you.

Here's the link.

My suggestion would be to go to Tom's after reading the
"filtered" version for a more extensive explanation.

Strictly out of scientific curiosity, is the reduction in APs
while gaining coverage based on similar power settings in both
hardware sets, and how do you answer the “yeah, but what about
client capacity concerns in dense areas?” question when the
number of APs and uplinks to the network is reduced? Again, no
axe to grind, genuinely curious.

I know Cisco’s CAPWAP solution seems to strive to keep APs at
less than full power. It’s even a metric in the RMM panel in
WCS “AP’s at maximum power” and the lower your percentage the
“better” things are considered to be, generally speaking. At
the same time, we probably all have spaces where maybe 3 APs
would fill the building, but three times that are used to keep
cell size small and users per AP at a ratio that delivers
higher client throughputs on the wireless shared media. In
this case, we could certainly reduce our AP counts by upping
the power, but it comes with trade-offs.

I guess I’m wondering how much of the Ruckus advantages are
philosophical (simply use less APs at higher power to cover
same space) and how much is technical wizardry.

We have almost completely converted to Ruckus from Cisco and
Extreme.

We have had very little need for support; the things just
work. We have reduced our AP numbers by over 30% with better
coverage. Once installed in a dorm setting we have never had
to go back other than one device that drowned from a leaking
air-conditioner pan. Our dealer replaced the device at no cost
even though water damage of this nature is not covered.

The indoor models and outdoor function well and deliver
outstanding data, video and VoIP. We are also using the
wireless point-to-point bridge at a distance of 500 yards with
throughput at 250MB. We have the p2p pair on portable stands;
one had blown over during a very bad storm but was able to
keep connectivity when hanging upside down with the main dome
facing a wall 180 degrees away from it's partner. We didn't
realize the issue for several days since it never went down.

We use a Zone Director 1000 to establish a mesh group and to
keep track of rogue devices. I would like a 3000 but we don't
have that in our budget lines at the moment. We have over 100
APs throughout the campus.

We have had them almost 2 years with no issues. Client
problems have not been an issue.

Amazing devices.

Looking for feedback from any institutions using Ruckus as
their WLAN solution.

Comments on their support, WAPs, Controllers, client problems
and any other related topics would be appreciated.
