Receiver sensitivity Lr-Wpan

[mts dominic]

HI,

I have been trying to find the exact piece of code  that sets the receiver sensitivity(PER<1%) in the Lr-Wpan models and have not been successful. I have noted the code below in Lr-wpan-phy.cc but this has nothing to do with PER

// default -85 dBm in W for 2.4 GHz
  m_rxSensitivity = pow (10.0, -85.0 / 10.0) / 1000.0;

could someone help me please

Thanks

Hi,

please check the latest changes in the repository.

About the Sensitivity, we (the devs) had a quite long discussion, and it's not going to be a mutable parameter for now.

The reason is: the sensitivity is a parameter you don't "set". You measure it.
You build a receiver and, depending on the electronics you have, you'll get a sensitivity. The standard only states that you need to have a minimum one (which is pretty easy to met).

In the simulator, we may allow to set the sensitivity, but it will require a bit more of work. The point is: the sensitivity is changed by adding (or removing) the thermal and processing noise from the received signal.

The current model's sensitivity is far better than -85 dBm, of course. It's about -106 dBm The value comes out (of course) from measures.

Cheers,

T.
