* The noise source radio is used to simulate ambient background noise or
|
|
* point-sources of external interference (e.g. Wifi basestations).
|
|
*
|
|
* Note that interference generated from these radios are different from
|
|
* transmissions; they will not appear in the radio logger but may still
|
|
* hinder or interfere with ongoing transmissions.
|
|
*
|
|
* Noise source radios require significant processing resources in comparison
|
|
* to only transmission radios.
|
|
*
|
|
* COOJA's radio mediums may or may not choose to respect noise source radios.
