Known subclasses

Name Type Description
Ieee80211DimensionalRadioMedium compound module

This radio medium model uses dimensional transmission power (that changes over time and/or frequency) in the analog representation. It must be used in conjunction with the Ieee80211DimensionalRadio model.

Ieee80211ScalarRadioMedium compound module

This radio medium model uses scalar transmission power in the analog representation. It must be used in conjunction with the Ieee80211ScalarRadio model.

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.

neighborCacheType string ""

NED type of the neighbor cache model

communicationCacheType string "VectorCommunicationCache"

NED type of the communication cache model

rangeFilter string ""

filter parameters that control when radio frames are sent to receiver radios

radioModeFilter bool false

when enabled the radio medium doesn't send radio frames to a radio if it's neither in receiver nor in transceiver mode

listeningFilter bool false

when enabled the radio medium doesn't send radio frames 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 radio frames to a radio if it the destination mac address differs

recordCommunicationLog bool false
