freq_ is used for calculating lambda_ (the wavelength). The lambda_ value is 
stored in the packet-stamp in each packet. The PacketStamp class has a method 
called getLambda.
"grep -s getLambda *" gives

Binary file ns matches
packet-stamp.h:  inline double getLambda() {return lambda;}
propagation.cc: double lambda = ifp->getLambda();   // wavelength
shadowing.cc:   double lambda = ifp->getLambda();   // wavelength
tworayground.cc:  double lambda = ifp->getLambda();     // wavelength
tworayground.cc:                                         t->getLambda());
tworayground.cc:                                         r->getLambda());
wireless-phy.h: inline double getLambda() const {return lambda_;}
Binary file wireless-phy.o matches

This is nothing I am sure of but it looks as if lambda is only used for 
calculating propagation in thoose files.
