David - Thank you, I understand it! But how did you get your computer powered when you were doing experiment outside? The laptops in our lab are very limited. Thank you!

We ran off-grid for a week like that, recharging the battery in place as needed with whatever power sources were handy. -- David On Nov 30, 2008, at 7:20 PM, Bill Stevenson wrote: Hello, all! We are utilizing USRPs to test the transmission range under some certain circumstances, say different modulation schemes. We are planning on testing the range outside, say in a football field since that condition is similar to the free space environment. But how can we get power for USRPs when we are testing outside? Could anybody tell me a decent way to power USRPs up without connecting the power cable to the extension board inside the building? What kind of batterypack can we use for the USRPs if battery is doable? Thanks a lot!
