[ns] how to test 802.11 in 60km range?

[Haiying \(Julie\) Zhu]

Dears,

 

I download the ns-allinone-2.29 package.  There is 802.11 included.  I
created a BS and several MS, when they are all within the range of 1km,
everything is fine.  When I change the MS position to be 50km from the BS, I
got "warning: Route to base_stn not known: dropping pkt".  Could any one
tell me how to fix this problem?  I would like to test how 802.11 perform
when MS and BS are 50km apart, with enough transmit power.

 

Thanks,

Julie
