Yep, if you're measuring amps like I was, the actual wattage can vary quite a bit depending on what exactly the voltage is. I would agree that 6 watts is a good number to use. ________________________________ From: [email protected] [[email protected]] on behalf of Josh Luthman [[email protected]] Sent: Wednesday, September 25, 2013 1:07 PM To: Randy Cosby; WISPA General List Subject: Re: [WISPA] ToughSwitch Question
Yup, definitely close, but when the radios are doing 3-5 watts it's kind of hard to measure (ie from 3 watts on the meter could be 2600-3400 mw). That's why I'd tack on a couple of watts when doing the math for batteries (or panels).

But from what I have seen, generally V x a = W is a going to be pretty close.

This came from Ubnt themselves in Vegas last year (it almost made it a year). So I took the new one in the box and put it in. I did all of the measurements on the AC side because I have a cord that enables me to easily do this. To measure the DC side, I'd have to cut open the wiring and I'd probably throw it away afterwards. 121.4 to 122.2 vac default (powered on, logged into it) 0.05 amp enabled all 5 poe ports (24v) no change put on old ns2 got .07 amps put on ns5m got .09 amps Now I'm not very confident in saying a Ubnt radio is only 2.5 watts (122vac * 0.02amps), but at idle I can't say that's impossible. It definitely went up another 0.01 amps while booting, but lost it when it was fully booted.
