Testing Wireless Performance

[JB]

We are using test equipment from CMC (www.cmc.com).  They simulate 64
clients per unit.  They work fairly well.  To make them really useful you
would drive them with a smartbits or linux traffic generator or something
like that.  Internally they only support icmp so in order to any real
testing using that you have to make sure you turn off any icmp limitations
or DoS prevention in the kernel.

I'd say: don't call it production, but field testing.

Start giving the service as an experimental set up, and make the people
being "used" as lab rats feel like privileged users which will get
service before it is operational. Take your measures and react
accordingly.

They call it marketing ;-)

Seriously, it will be too expensive to build a test lab like the one
you want, so, make a field trial instead.
