IRadioMedium

module interface

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.

Implemented by

Name	Type	Description
DimensionalRadioMedium	compound module	Radio medium model that uses dimensional representation (time and frequency domain) for signal power. Provides more accurate modeling of signal propagation, interference, and reception compared to scalar or unit disk models. Suitable for simulations requiring detailed physical layer behavior.
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 dimensional analog model in radios.
Ieee80211RadioMedium	compound module	This radio medium model is part of the IEEE 802.11 physical layer model. It must be used in conjunction with the ~Ieee80211Radio model or other derived models.
Ieee80211ScalarRadioMedium	compound module	This radio medium model uses scalar transmission power in the analog representation. It must be used in conjunction with the analog model in radios.
Ieee802154NarrowbandDimensionalRadioMedium	compound module	(no description)
Ieee802154NarrowbandScalarRadioMedium	compound module	(no description)
Ieee802154UwbIrRadioMedium	compound module	(no 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.
ScalarRadioMedium	compound module	Radio medium model that uses scalar representation for signal power. Provides a simpler and more computationally efficient alternative to dimensional models by representing signals as single scalar values rather than as functions of time and frequency. Suitable for simulations where detailed physical layer behavior is not required.
UnitDiskRadioMedium	compound module	This radio medium model provides a very simple but fast and predictable physical layer behavior. The idea behind this analog model is to describe transmissions with a few distance-based parameters: communication range, interference range, and detection range. Whether the reception is successful or not depends on the distance between the transmitter and the receiver.
