In my opinion/experience at least two-fold over-sampling is to be recommended with OFDM, The standard 802.11n has a mode with 40MHz bandwidth (not to mention 802.11ac). I have the feeling the dynamic range of 48dB is somewhat small for OFDM. Especially without fast AGC.

It's extremely cool. I verified that the 36MHz bandwidth option on the XCVR2450 actually works (and it does). With this kind of bandwidth it is possible to investigate true 802.11n and LTE signals (I wish we had this feature for TX as well). Many thanks Marc!
