[MLB-WIRELESS] Max distance, Power over ethernet and 5v AP's

The other option is to run 48V to the AP, and use a splitter at the 
other end (just before the AP) to regulate the voltage back down to 12V. 
I'm not sure on the length of this method, but I'd assume it would be 
pretty good.

Linksys sells such a device for either 5V or 12V devices, and included 
the DC adapter, injector and splitter. They are made primarily for 
Linksys devices, but I don't see any reason why they won't work on 
something different (provided the DC plug fits, but with a new connector 
and a soldering iron, that isn't an issue).


I've used a few at work for powering WRT54GL's (12V version though), and 
they work fine.

If your adventurous enough, I suppose you could build a similar device.
