So you give me additional reason to stay with Linux and not to migrate to FreeBSD since even a basic wireless adapter which came with your Sony isn't supported by FreeBSD. To be honest, I don't know if your Sony wireless adapter is supported by Linux, but in general, I think linux is more

Hi, The main issue is this: I really don't like the USB driver stuff in the kernel. When I last checked, there was no clean example of a wifi or ethernet driver which handles all of the odd corner cases of things correctly. So you'd end up with things like taskqueues still running whilst the NIC

FreeBSD TDMA: Legalizing 440MHz 802.11 modems

2014-08-27 Thread Bart Kus
Hello, I'm wondering if you can tell me if it's possible to modify the FBSD TDMA code to make this card: http://www.doodlelabs.com/products/radio-transceivers/sub-ghz-range/420-450-mhz-dl435-30/ legal to use in its intended spectrum. By default the card violates two Part 97 rules: 1)

Hi! So, I'm not sure if we can underclock it _that_ far. The 5/10MHz channels are implemented by underclocking various parts of the chip, which results in everything being some fraction of 20MHz (or 2x clocking it, resulting in 40MHz.) Bringing it all the way down to 200KHz is a pretty tall ask.

2014-08-27 Thread Bart Kus
Is the underclocking affecting the digital domain only? Or would there be some analog frequency response curves that would start falling off too? If it's a digital-only underclock I don't see why there would be any degradation (aside from the obvious speed decrease). Is this easily testable

I'm guessing the chip generates its own internal clocks from an external reference. Can that PLL be slowed down ahead of timers overflowing? Hopefully the PCI clock is generated independently. Also, I think Mikrotik implements narrower bands by dropping subcarriers instead of slowing down

Well I'll be damned, looks like 5MHz mode on Mikrotik is just slower signalling! All 52-subcarriers are indeed there, although a little hard to see: If you count peaks left/right of center, you'll get 26. 2*26=52, so that's every sub accounted for. Can you point me at your 5/10MHz docs?
