Fairwaves[Fairwaves -- concluded on 2013/04]
Fairwaves project is aiming at removing one more obstacles on the way to cheap and ubiquitous wireless networks --absence of free (open source), yet production quality building blocks for wireless equipment. There are plenty of expensive proprietary solutions you can use for coding.
Fairwaves is set to develop an Open Source framework for PHY and MAC levels of wireless protocols which will allow "free as in beer" development. It should foster innovation in the wireless communications and allow more projects like OpenBTS and Opendigitalradio to emerge.
