A colleague of mine needs estimates for how much it would cost to provide backup power to Ubiquiti Nano http://www.ubnt.com/nanostation wireless APs, they run on 12 watts of power. It's for a large scale project, estimated to run over 140 APs. -- John Wesonga

Unless they are in a meshed network - i would go for POE and instead provide redundancy on the POE switch. If its a meshed network - 12watts can be achieved through solar panel, battery and inverter. Regards, Michuki.
Thanks for the feedback, we had received some very disturbing quotations which generally implies a complex solution but its clearly the simplest and cost effective solutions do exist.. On Mon, Oct 17, 2011 at 5:08 PM, Michuki Mwangi <michuki@swiftkenya.com>wrote:

Please send more info off list. We have done these kinds of installs before. ;) Blessings, Crystal On Mon, Oct 17, 2011 at 5:25 PM, John Wesonga <johnwesonga@gmail.com> wrote:

Kwani he wants to supply them with backup power from a single source? Then perhaps s/he can multiply the power consumption of each unit by 140 times the number of hours s/he foresees keeping them up on backup. Is it called power factor or something? Areba can tell better, although I see he's already given you the solution - a 600VA UPS for each! I think a 600VA UPS can keep one nanostation running for approximately 30 minutes???? I am not sure, but I'd love to test it if I were you. Let us know how they ultimately go it.. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ I can't hear you -- I'm using the scrambler.

I gave the solution for a UPS for the simple reason that you just said backup power, and I assumed that youre not placing all those nodes at the same point (wouldnt make sense). and that since you are looking for [backup] power, you have primary power supply. If you do not have primary power to begin with, solar powered is your best bet. Best thing though, have an energy audit done prior to signing LPOS...
