IEEE 802.15.4 MAC sub-layer implementation now available

19 May 2004 Telecoms, Datacoms, Wireless, IoT Integrated Solutions

Chipcon has released IEEE 802.15.4 compliant MAC software, offered free under a licensee agreement to customers involved in ZigBee and IEEE 802.15.4 compliant product developments.

The IEEE 802.15.4 MAC sub-layer implementation runs on the company's newly-released CC2420DBK hardware platform, which includes an Atmel AVRmega microcontroller. As the software is written in C it can easily be ported to other platforms. The MAC sub-layer software may be configured for different user needs and applications such as a high-throughput router node or a low power sensor node. The software includes functions such as collision avoidance, beaconing, association, scanning, access control, AES encryption and authentication. These functions together provide the user with a highly reliable link between two or more MAC entities.

The IEEE 802.15.4 standard was approved in May 2003 ( www.ieee802.org/15/pub/TG4.html) and provides a worldwide standard for low data rate solutions with multimonth to multiyear battery life and very low complexity. It is intended to operate in an unlicensed, international frequency band. The typical applications are home and building automation, industrial control and monitoring systems, wireless sensor networks, remote controls and consumer electronics.
