Submission + - HackRF, an open source SDR platform (kickstarter.com)
lipanitech writes: HackRF is an open source hardware project to build a Software Defined Radio (SDR) peripheral. SDR is the application of Digital Signal Processing to radio waveforms. It is similar to the software-based digital audio techniques that became popular a couple of decades ago. Just as a sound card in a computer digitizes audio waveforms, a software radio peripheral digitizes radio waveforms. It's like a very fast sound card with the speaker and microphone replaced by an antenna. A single software radio platform can be used to implement virtually any wireless technology (Bluetooth, ZigBee, cellular technologies, FM radio, etc.).
