Building my own WISP II: Teach me about POE injectors.
July 28, 2014 3:43 PM Subscribe
As part of my continuing attempt to build a wireless bridge
to bring the internet to my house, I have obtained two used Tranzeo TR902-11f 900Mhz wireless access points sans any power supply. Please help me find (cheaply) POE injectors for these WAPs.

According to the data-sheet[pdf]
they are supplied by POE at 18v 1.1a (output) with 7 watts max. I have never set up a POE device before, but I assume that I need two POE injectors at 18v 1.1a (output) but, do they also have to be specifically at 7 watts or is the datasheet telling me that 7 watts is the maximum output of the WAP?
Also, in case anyone is wondering, trees with leaves do indeed form an intermittent but effective barrier to 2.4Ghz wireless signal transmission even at short distances (< 500ft) with no other barriers. Also, cheap 2.4Ghz panel antennas are not particularly directional. In addition, it's possible to find much cheaper non-Ubiquiti branded 900Mhz WAPs on your favorite internet auction website.
