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
