IEEE 802.15.4 MAC User Guide PRELIMINARY

Development
Background
The following paragraphs introduce this User Guide for the Atmel designed Medium
Access Control (MAC) layer utilized in an IEEE 802.15.4 (hereinafter referred to as the
IEEE standard). The subject, purpose, scope, and plan of development of this user
guide is provided as well as a brief background of the IEEE standard and the ZigBee™
Alliance. A list of supporting documentation is also provided.
This user guide describes the interface between the application/network and the MAC
layer as implemented by Atmel's IEEE 802.15.4 compliant firmware.
This guide provides the application programmer with a technical description of the ser-
vices provided by the MAC. MAC and callback functions are described in detail so that
the programmer can design a program that can fully utilize the services of the MAC.
This document is not intended to replace the IEEE standard. The focus of this material
contained within is on the interface between the Atmel
For additional details regarding the IEEE standard, the user is encouraged to reference
that document.
This user guide approaches the interface to the MAC by presenting an overview of the
MAC and its interfacing layers. A section on using the MAC services presents an intro-
duction to the function calls used to invoke MAC services and the callbacks that the
MAC returns to the application/network layer. The necessary source and include files
are listed as well as a presentation of the PIB. The main function is discussed and how
to reset the device is presented. Appendixes A through D contain lists of function call
semantics and parameters. Appendix E presents a list of all data elements and their
detailed parameters.
Wireless personal area networks (WPAN) are used to convey information over relatively
short distances. Unlike wireless local area networks (WLAN), connections effected by
way of WPANs involve little or no infrastructure. This feature allows small, power-effi-
cient, inexpensive solutions to be implemented for a wide range of devices. IEEE
802.15.4 defines a standard for a low-rate WPAN (LR-WPAN).
The ZigBee Alliance is developing standards for the application and network layers that
will use the LR-WPAN defined by the IEEE standard. OEMs are designing these layers
to accommodate their needs and their customer’s needs. The application and network
layers can theoretically be anything the user desires. From point-to-point (star) net-
works that report temperatures to self healing multi-hop mesh networks that not only
