Re: [Discuss-gnuradio] Gnuradio 802.11g

[Saulo Queiroz]

Also, in [1]  authors claim a version of gr-ieee802-11 that is CSMA-CA-capable on N210

(i think you have to switch from master to the agc_and_csma branch in [2]).

However the solution does not implement ACKs i.e. it is suitable only for WiFi broadcast

communications as is the case of some 802.11p scenarios. Check whether it can

be adapted to your need.

Well, if you implement a lot of the IEEE802.11 in the FPGA, yes, that could work. But: then it would hardly be a GNU Radio implementation.
Also, please don't expect the poor CPU of the E310 to process 20MHz of bandwidth itself; it's a power-efficient ARM, and you'll need a relatively new PC CPU to run things like FFTs at that rate.

Hi thank you for the reply.

I have acces to the USRP E310, is it posible that this hardware will support the correct timings using the RFNoC?

Hi Gabriel,

No. In most of boards, the delay between PC and device turns unfeasible

the work of critical time operations like csma count down. Depend on your

hardware, you can get that with RFNoC module from Ettus, but with hard work.

Hi

Is there any fully working implementation for the 802.11g protocol in gnuradio capable of working as an access point?

I was wondering if there exist one with the MAc layer fully developed, since i've only seen simplyfied MAC layers, or is there a software/hardware limitation.

Thanks in advance
