We are looking into using a cell connected router to provide wireless inside a truck. Right now we are trying to figure out how to power all of it with a UPS, etc that can survive freezing temps and very hot temps that the inside of the truck will be subjected to. I know some of you have provided wireless inside buses for students and other applications. Any thoughts on how to handle the varied environment?

Seems to me the power supply in the truck is your best bet. The router probably runs on DC at relatively low power compared to something like a car stereo, and the truck's battery would make as good an all-weather UPS as anything I can think of. The key questions are, what are the power requirements of your router, and how long might it need to run without starting the truck?

Check out http://www.powerwerx.com/batteries-chargers/ I've used products from this company for a few projects and have always been happy. Look at either a battery separator or battery isolator and, as Jonathan recommended, use a separate battery with the AH rating you need for your project. Be careful about what you hook up to a car power system, 12 volts doesn't always mean 12 volts. You will see a swing of +- 25% between when the battery is low and what the alternator puts out. Either check to make sure that the gear you're hooking up is happy with a large range, or take extra steps to smooth out the power. Ham radio folks have been running RF gear in cars for decades now. See what resources you can dig up with that in mind. -Luke =-=-=-=-=-=-=-=-=-=-=-= Luke Jenkins Network Engineer Weber State University
