The analog model describes how the analog representation of the transmissions is turned into the analog representation of the receptions.

The antenna model describes the physical device (a part of the radio) which converts electric signals into radio waves, and vice versa.

The error model describes how the signal to noise ratio affects the amount of errors at the receiver.

The neighbor cache model computes the affected set of receivers on the medium for a given transmission.

The obstacle loss model describes the reduction of power as the signal passes through physical objects.

The path loss model describes the reduction of power as the signal propagates through space.

This module interface provides an abstraction for the interface of different physical layers.

The propagation model describes how a radio signal propagates through space over time.

Prototype for radio modules. Radio modules deal with the transmission of frames over a wireless medium (the radio medium).

The background noise model describes the thermal noise, the cosmic background noise, and other random fluctuations of the electromagnetic field that affect the quality of the communication channel.

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.

The receiver model describes the physical process which converts electric signals into packets.

The transmitter model describes the physical process which converts packets into electric signals.
