The default operation of the Adaptive Data Rate (ADR)

I need to simulate a LoRa network that includes the Gateway and the End Devices. I need to simulate the operation of the default Adaptive Data Rate by the network server and the end devices.

Can this be done using a simulator?

Can the network server be simulated using the simulators?

What types of simulators can be used to simulate the LoRa and the ADR?

Are there any images for the firmware of the hardware equipment that can be used to simulate the operation of the LoRaWAN network components?

Just 2 questions at this point:

  1. Why?

  2. How does this relate to TTN? (the purpose of this forum…)
