don't know about "for Mac", but Lucent definitely has a cool system that now
does 8MB -- their original one did 2MB. Network Magazine just gave them one
of their awards for the previous year. We just set up a trial in our library
(all PC). The radio broadcast antennas are simple, unobtrusive and have a box
similar to a minihub that plugs into the rest of your network. They handle
roving connection, so that a laptop moving out of range of one and into the
range of another will automatically transition without a break in connection.
The antenna receiver cards only stick out about an inch from the side of the
laptop.

We have a large library and found that with two antennas placed diagonally at
opposite corners we could easily cover the main floor. We could receive the
signal up one floor through the floor (this is a reinforced concrete 26 story
library) and book stacks. Two floors was iffy and you would have to be
vertically directly over the antenna. With a single hub point, something like
the elevator shaft would completely block the signal because of all the metal.

It is slightly expensive compared to a wired system, but not totally
outrageous. If your wiring situtation becomes overly complicated or difficult
for one reason or another or you just need the flexibility and convenience,
this would do it. You can actually go out on the lawn outside the library by
the pond and lay back with your laptop, connected to the network.

Just thought all that might be of interest to people on the list.

So, if you are searching the web, look for Network Magazine and look for
Lucent.

I could tell you more if I were at work, but given that info, you can
probably find it just as easily on the web.
