[ns] Mac/802_11 wireless link bandwidth

["Susan Tsao" <SusanTsao@WoodsideNet.Com>]

Hello,

I'm using the CMU wireless extension to run a simple simulation of two
mobile node
communicating over a wirless link . Does anyone know the default
bandwidth (link transmission
speed) value used for the wireless link? And how can I change that
value?

I added the following line to my *.tcl script:
	Phy/WirelessPhy set bandwidth_  10e6
but that didn't change my simulation results. 

I've also played with:  Mac/802_11 set bandwidth_  10e6
but I'm confused as which parameter actually determines the link
transmission speed. 

Thank you.
Susan
