[ns] need help regarding Mac/802.11Ext

[Zubiya ..]

Hi,
I need guidance for using Mac/802.11Ext.

1) How to set different data rates while using Mac/802.11Ext?

2) What does the following parameter mean?
              * Phy/WirelessPhyExt set noise_floor_             2.512e-13
;#-96 dBm for 10MHz bandwidth*

does it change with different modulation schemes?

Thanks in advance
