I recently helped set up a wireless LAN for my church and associated school.
There were 3 buildings involved, each seperated by about 150 m. One of
the other committee members worked for Lucent and we were able to get a
WaveLAN installation at a good price (cheaper than a cable run, we paid cost
for the hardware and the Lucent technician who did the actual installation
volunteered his time). The system is 'rated' for 11 MBps, but the actual
throughput is closer to 3-4. This is not a problem for this situation, but
I could see where it might be for some others. Our internet connection is
directly to the school building, so the student/teacher traffic, which puts
the mosts traffic on the system, does not even hit the wireless segment.
For the parish priests and administrative staff in the rectory, the speed of
the wireless link has not been an issue.
In my day job, I work for a small private investment firm, and if we told
one of the traders or analysts or partners that we were putting then on a
shared 11 MBps segment, they would freak out, whether they needed more
bandwith or not.

Also, from my experience actual throughput is much less than 11 MB. I've
been lucky enough to test the Cisco Aironet, Compaq, and RadioLan offerings.
The RadioLan wireless has the best actual throughput, but they don't conform
to the 802.11 specification, operating at the 5.8Ghz range as opposed to the
2.4Ghz standard. The Cisco Aironet series drivers stink for win2000, and NT,
with many little issues, but I'm sure they'll improve them since Aironet was
just bought by Cisco. We use the RadioLan stuff in production, but we'll
move to the Cisco Aironet around the first of the year, as soon as Cisco can
catch up on orders. I hear that the Lucent offerings are
Just make sure to use encryption. And I would agree with most that the
wireless has its uses, but won't replace wired LANS for a while.

Something to note, the 11MB is shared by all users of the base station, they
don't each get 11MB.
