Re: [Discuss-gnuradio] IEEE 802.11 receiver not working for high sampling rates

Hi, As Marcus suggested, I put a frequency sink directly to the receiver to look at the signal. Both at 1 MHz and 10 MHz the signal is noisy. The power is around -120 to -100 db. However, in the case of 1 MHZ all packets sent by the USRP transmitter are received correctly with almost negligible pa

Hi, well, the next step here would pretty clearly be going through the flow graph and finding out where things don't work – you'd typically start with something like a frequency or waterfall plot directly at the receiver, and then look for packet errors, and so on. Use a Qt time sink to look for c

Hi Victor, I am using GNU Radio flow graph and it's actually IEEE 802.11 modules wifi-tx for sending data. Also I am not using virtualized environment and my ethernet port is 1Gbps. On May 25, 2017 11:11 AM, "Diez Victor" wrote: > The problem could be the transmission of data via ethernet port.

The problem could be the transmission of data via ethernet port. Are you working under virtualized OS conditions? These could be the origin of your problem, virtualized ethernet ports don’t reach enough high data rates. Another possibility could be that your ethernet adapter isn’t a gigabyte ethe
