I am new to gnuradio and trying to do some work based on 802.11. Through
understanding, the current implementations of 802.11-like schemes over
gnuradio are mostly limitted by the processing delay on and between the
computer and USRP boards, eapecially due to the bottleneck of the USB
connection between the USRP and host computer. Due to such delay
limitations, in the implementations to 802.11 with USRP, the bandwidth
to be scaled down and some tuning to the IFSs has to be done to make the
Now USRP2 offers Gigaehernet connection and more powerful signal
hardwares. To what extent USRP2 solve the limitations of implementing a
full-powerful 802.11 over the current gnuradio framework (together with
new m-block)? Besides USRP or USRP2 boards, any other issues mattered?
still need to scale down the bandwidth and tune the IFSs? Are there any
working implementations or studies which fully exploited the newest
Thanks a lot.
