At the time there weren't any midspans released that would provide the
full 20 watts of power required by the 1252. It will run off of the
standard 802.3af power, but then you only get a 1x3 rather than the 2x3
capabilities.

Midspans have been available for several months now -- when were you
looking?

Q. Will third-party Power over Ethernet mid-span devices be able to
consistently power the Cisco Aironet
When I went looking for midspans back in June/July, there was only one that
actually supported the required Cisco signaling to enable high-power mode on
the AP. The midspan is/was the PhiHong POE125U-4HP four port unit. The other
midspans required a dongle at the AP to split the power back off

We are running 11n in 2.4 GHz on the 1252's, but only at 20MHz. 40MHz in
2.4 MHz seems like a very bad idea because of the lack of
non-overlapping channels.
As for range, the building I'm

As far as the range is concerned we do get a greater range with the
1252's. I can't say we use this as a feature, because we didn't have a

Thanks for sharing that. Have you ever considered midspan devices for
when you need more than a handful of bricks?

A lot depends on what kind of construction your building is -- brick,
concrete and concrete block is entirely different from drywall and
open spaces. The other aspect is your definition of full coverage. If
you want the location functionality to work, you need much higher
density and different
more based in reality.
