The primary function of wireless communication protocol
is to transmit and/or receive information between two
nodes. The Media Access Controller (MAC) layer
provides the basic channel access, addressing and data
transmission/receiving functionalities, on top of the
Physical (PHY) layer that handles raw data. In the
standard Open Systems Interconnection (OSI) model, it
serves as the Data Link Layer (DLL). Because of the
wide variety of possible implementations in the PHY
layer, the MAC is the lowest possible layer to
standardize in the software for communication protocols.
This application note defines the Microchip MAC layer,
MiMAC, for communication protocols and transceivers
supported by Microchip for short-range, low data rate
and low-power wireless applications.
Implementing MiMAC benefits wireless application
developers in multiple ways:
• Traditionally, wireless communication protocol
stacks are complicated to implement and difficult
to use. With the new definition of MiMAC, it is
possible to make the protocol stack available for
widely different RF transceivers. AN1283
