Buffers, buffers everywhere... It depends on the sampling rate and technology (USB, ethernet, direct PCI), but in general 1msec is achievable, 10microsec is not achievable. That's why BladeRF-wiphy ( https://news.ycombinator.com/item?id=25814237 ) implements the lower level phy on FPGA - there's no way to reply
an IEEE 802.11 ACK frame within 10 microseconds of the end of the received frame, as required by the standard. |
