Hi guys I'm looking for a nice GUI that can plot my AoA calculations in a some kind of a compass looking GUI. Does anything like that exists? or do i have to build one of my own? Don't really know how, and would prefer not to start learning Python right now (on a deadline). Any help would be much

Hi guys, I am currently working on a project for my university, where i'm trying to locate cellular phones using SDR (USRP B210). The idea of the project is to be able to find survivors/victims in disaster areas, such as earthquakes, by assuming they have their cellular on them. What i did so far

2016-01-09 Thread Meny Sidar
Hi guys, Is there a way, without establishing communication between a cellular phone to a base station, to calculate TDOA (or TOA) from my USRP B210 to the cellular nearby? My goal is to determine the distance to the cellular phone, or alternatively to know if i'm getting closer/further to it. Th

[Discuss-gnuradio] How can i determine my current phone's frequency?

2015-12-17 Thread Meny Sidar
Hi guys, I want to know which frequency my cellular phone is using (for uplink - UMTS). I'm using USRP B210, i tried the spectrum analyzer tool but i don't really know what to expect- isn't the transmitting power of my cellular supposed to be higher (in a single frequency) than all other frequencie
