This radio medium model provides a hypothetical radio that simply uses one of the well-known modulations without utilizing other techiques such as forward error correction, interleaving, spreading, etc. It must be used in conjunction with the ApskScalarRadio model.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Extends

Name	Type	Description
RadioMedium	compound module	The medium model describes the shared physical medium where communication takes place. It keeps track of radios, noise sources, ongoing transmissions, background noise, and other ongoing noises. The medium computes when, where and how transmissions and noises arrive at receivers. It also efficiently provides the set of interfering transmissions and noises for the receivers.

Parameters

Name	Type	Default value	Description
physicalEnvironmentModule	string	"physicalEnvironment"	module path of the physical environment model
signalAnalogRepresentation	string	"scalar"
rangeFilter	string	""	filter parameters that control when signals are sent to receiver radios
radioModeFilter	bool	false	when enabled the radio medium doesn't send signals to a radio if it's neither in receiver nor in transceiver mode
listeningFilter	bool	false	when enabled the radio medium doesn't send signals to a radio if it listens on the channel in incompatible mode (e.g. different carrier frequency and bandwidth, different modulation)
macAddressFilter	bool	false	when enabled the radio medium doesn't send signals to a radio if it the destination mac address differs
recordTransmissionLog	bool	false	logging parameters
recordReceptionLog	bool	false	when enabled the medium writes one line per reception into the communication log file
