[ns] About wireless bandwidth

["Wings" <wings@cis.nctu.edu.tw>]

Dear ns-users,

 

    The default value of wireless bandwidth is 2Mbps.

Because wireless channel is broadcast environment.

if only one TCP flow is start up,it can use all the channel.

But its rate can't achieve 2Mbps. Why?

 

    Thanks.

 

Best regard,

Wings
