IRx

module interface

Interface for Rx processes. The Rx process checks received frames for errors, manages the NAV, and notifies other processes about the channel state (free or busy). The channel is free only if it is free according to both the physical (CCA) and the virtual (NAV-based) carrier sense algorithms. Correctly received frames are sent up to upper layers, corrupted frames are discarded.

Implemented by

Name	Type	Description
Rx	simple module	Responsible for checking frames received over the radio for errors, for managing the NAV, and for notifying other processes about the channel state (free or busy).

Used in compound modules

Name	Type	Description
Ieee80211Mac	compound module	Implementation of the 802.11 MAC protocol. This module is intended to be used in combination with the Ieee80211Radio module as the physical layer.
