    2.4GHz n with 40MHz channel width (Manufacturing\FCC testing)

    felix_turgeon

      We are developing our FCC test firmware for the BCM43341B0.  We are building on our original firmware for the 433262a2.

       

      Our problem comes when we try to transmit using 2.4GHz 802.11n with the channel width set to 40MHz (upper or lower sidebands).

       

      The 40MHz width seems to work fine for 802.11a and 802.11n as long as we use 5GHz for the band, and 20MHz width works fine with both bands using any 802.11 data rate (a/b/g/n).

       

      Is 40MHz wide channels currently supported with 2.4GHz? or is this a known deficiency in the BCM43341B0 WICED firmware?
