Fwiw I am working on an open baseband chip. It is illegal to use in regular networks yes, but if that gets fixed we will now have an open chip. Afaik it might be legal if you use it on your own premises (at home or if the organizers of a conference allow it - I might ask C3 folks)
Like the prototype is gonna consist of an SDR, which is quite expensive (think 800€ per baseband), but after I get the prototypes down I should be able to bring the cost down 1-2 orders of magnitude at least, by making my own ICs.
