Bridge for REMOTE OUTDOOR project.

I'm trying to use wifi bridges to connect a seismic datalogger high on a cliff to a computer a half mile away in a valley. This has been successfully done with a colleague's equipment using Senao/Engenius NCB-????(indoor model). So just order the same thing, right? Well, I tried... and I got a device (NCB-3220) that uses 48Volts, not 12Volts, despite the Engenius spec sheet listing the device at 12Volts, but it came with an AC->48VDC adapter. This is useless... it is infeasible to drag 4 12V batteries up the cliff.

I also ordered 2 outdoor bridges from Senao/Engenius, (the EOC-3220+ and the EOC-8610). BOTH are 48 Volts, BOTH reset themselves randomly (and then you have to go in via serial port to reset to factory defaults), one (8610) cannot even be reset to factory defaults, and so far, the customer service from ENGENIUS has been AWFUL!

Needless to say, I'm pretty fed up with Senao/Engenius. I need a couple of wifi bridge of some sort, at least one needs to be 12 Volts, and... this is the kicker... they actually need to work! Any suggestions?

I use Linksys WAP54G devices, they are 12v and they can be setup as a bridge. There limitation is power output, it is limited to 22mw with factory firmware, but you can load a third party firmware that will take them to 84mw. Not sure if that will be enough for your needs.

Forty Eight volts is required for Power-over-Ethernet (IEEE802.3af) when powering a device through up to 100 meters of cat5 cable. The NCB-3220 has an internal voltage regulator to reduce the final PoE voltage for its internal circuitry. If you have a 12v adapter available, try operating the NCB-3220 with 12 volts. It might operate just fine if you will be using a short data cable..

Thanks guys -
I'll try and see if it works w/ 12V. It might... I'm just confounded why the adapter is 48V (yea, I know PoE is 48V).
