Hi Tom, define "embedded". If you use an x86 or powerful multi-core ARM
Single-Board-Computer, which I'd argue can be an embedded device,
then sure, I don't see any limitations with that compared to what
you can do on a PC. Of course, dealing with 20 MHz channels on a
poor ARM processor is very hard, so this might or might not work
out, and might require hand-tweaking system performance. Don't
forget that if using gr-ieee-802-11, you'll need a high-bandwidth
link to your SDR hardware – typically, Gigabit Ethernet or USB3,
the CPU power to handle the torrent of data that enters and leaves
your computer as samples through that link, the power to process
that data, and only if you've got all that covered and still have
CPU to spare to actually do something with your data payload, you
might consider doing a sensible network data rate benchmark. Generally, regarding rate: This is not 100.0% true, but in
essence: Either your computer is fast enough to run the flow graph
at the sampling rate you need to cover the full channel, or not.
It's not like "my slow computer can reliably use gr-ieee-802-11,
but to get great rates, I'll need a slightly faster one". Best regards, Marcus On 14.04.2017 18:58, Thomas Wilkinson
