Which firmware must be locked down? I was under the impression that is just retail end user devices, is the suggestion that chip manufacturers will not be allowed to sell parts to people who might make a non locked down device? Does that include if they don't supply firmware and the user writes their own/reverse engineers others? Sounds like a road to future regulating all rf hardware sale (stop people selling rp connectors as it's letting them circumvent the antenna limitations they were designed to impose?) Given the interference that caused this is a few incidents a year compared to the millions of units sold and that those cases were either bad users or caused by faulty devices it seems that the lock down would have to be total to prevent future incidents. Quite impractical. > Would I like someone to do this, Sure.

It think it would be cheaper and quicker to reverse engineer drivers for others hardware. Even if the cost could be covered to build it'd lag commercial products by years making it a difficult sell, and likely subjected to IPR claims from current manufacturers > If someone does the research and puts together a FPGA version That could be an interesting project. It may not help but we have an FPGA MIMO implementation we may be able to release to such a project (it may be unsuitable though, we've been making radio cameras https://www.google.co.uk/?gws_rd=ssl#q=bbc+r%26d+mimo https://www.google.co.uk/?gws_rd=ssl#q=bbc+r%26d+halfrf ) > and is looking for funding to convert it to a ASIC, I think you > could get funding. But that's not the question in front of us now. Yes, and if the lock down expands to chips too would have the same problem brandon
