Known subclasses

Name	Type	Description
FlatRadioBase	compound module	This module servces as a base module for flat radio models.

Extends

Name	Type	Description
Radio	compound module	The radio model describes the physical device that is capable of transmitting and receiving signals on the medium. It contains an antenna model, a transmitter model, a receiver model, and an energy consumer model.

Parameters

Name	Type	Default value	Description
radioMediumModule	string	"radioMedium"	module path of the medium module where this radio communicates
energySourceModule	string	""	module path of the energy source module which provides energy to the radio
initialRadioMode	string	"off"
switchingTimes	string	"ms 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0"	time parameters to switch between radio modes
sendRawBytes	bool	false	when true packets are serialized into a sequence of bytes before sending out
separateTransmissionParts	bool	false	when enabled the transmission of preamble, header and data part are simulated separately
separateReceptionParts	bool	false	when enabled the reception of preamble, header and data part are simulated separately
displayCommunicationRange	bool	false	if true communication range is displayed as a blue circle around the node
displayInterferenceRange	bool	false	if true interference range is displayed as a gray circle around the node
centerFrequency	double		center frequency of the band where the radio transmits and receives signals on the medium
bandwidth	double		bandwidth of the band where the radio transmits and receives signals on the medium
