WARP Project Forums - Wireless Open-Access Research Platform

When the channel is set to some frequency using  "warpphy_setChannel(GHZ_2, newChan)" , then only we can do carrier sensing  using " warpmac_carrierSense() " function.  One doubt here .

Can we do carrier sensing with out setting the channel as the particular channel ?

I want to do carrier sensing in all the frequencies. Then i have to set the channel to all the 14 frequencies and do the carrier sensing for all the frequencies as per your code.  Is there anyway to avoid setting the frequency before doing the carrier sensing?

Another doubt :: does   the "warpmac_carrierSense() "  function do the " energy detection"  of the received samples?

Please clarify these doubts.

Thanks,
