Changing bandwidth #51

Closed philipskotte closed 4 years ago

philipskotte commented 4 years ago

Hi!

I am simulating the simple-network-example.cc, but I can't figure out how to change the bandwidth for the simulation. Right now it is using the bandwidth of 125000 Hz, but I want to change that to 250000 Hz. Do you have any suggestions how to do this ?

Hi, to do that, you can change the configuration of channels in LorawanMacHelper. Keep in mind these two things:

Time on air computation with a 250kHz channel should be taken care of appropriately by the respective functions, no need to tweak that.

Hi again! Thank you for the answer! I just have one more question and that is in which file do you implement the size of the package that will be sent?

DvdMgr commented 4 years ago

This is decided by the application layer - typically, in the examples we use the PeriodicSender class.
