The Application/

The MAC Layer
The Physical
Layer
The Hardware
Abstraction
Layer
The application and network layers of the software solution are necessary components
of the final software solution. They comprise the highest levels of the software control
hierarchy and direct the Atmel MAC to perform lower level functions. Proper definition
and implementation of these layers ultimately allow the user to realize the final
application.
The MAC layer handles all access to the physical radio channel and is responsible for
the following tasks:
IEEE 802.15.4 defines the Physical Layer (PHY) as responsible for the following tasks:
The Hardware Abstraction Layer (HAL) is specific to a particular radio and interfaces the
common PHY layer to the physical radio. Due to the number of radios that are available
in the marketplace, Atmel engineers have designed and added the HAL as a module
that is changeable to meet the differing requirements of the various radios.
– Generating network beacons if the device is a coordinator
– Synchronizing the beacons
– Supporting PAN association and disassociation
– Supporting device security
– Employing the CSMA-CA mechanism for channel access
– Handling and maintaining the GTS mechanism
– Providing a reliable link between two peer MAC entities
– Activation and deactivation of the radio transceiver
– ED within the current channel
– LQI for received packets
– CCA for CSMA-CA
– Channel frequency selection
– Data transmission and reception
