Networking: Zigbee Alliance adds capabilities
The ZigBee Alliance , a global ecosystem of companies creating wireless solutions for use in utility, commercial building and consumer applications, announced it has approved comprehensive new features for the ZigBee specification giving more choices to manufacturers as they design ZigBee products. The organization says these new features significantly expand the capabilities of ZigBee, further strengthening its leadership position as the global standard for wirelessly connecting dramatically different devices into one, easy to install and use network.
The ZigBee specification offers all the wide-ranging features released in 2006, and adds new features, giving manufacturers greater flexibility when designing innovative ZigBee products. The original set of features published in 2006 is now known as the ZigBee Feature Set. An expanded set of features known as ZigBee Pro maximizes all the capabilities of ZigBee and facilitates ease-of-use and advanced support for larger networks. These features expand product development options available to manufacturers. The newly released Feature Sets are designed to interoperate with each other, ensuring long-term use and stability. Highlights of the expanded ZigBee Pro Feature Set include:
• Network scalability—Improved support for larger networks offering more management, flexibility, performance choices;
• Fragmentation—New ability to divide longer messages and enables interaction with other protocols and systems;
• Frequency agility—Networks dynamically change channels should interference occur;
• Automated device address management—Optimized for large networks with added network management and configuration tools;
• Group addressing—Offers additional traffic optimization needed for large networks;
• Wireless commissioning—Enhanced with secure wireless commissioning capabilities; and
• Centralized data collection—Tuned specifically to optimize information flow in large networks.
Access to the updated ZigBee specification is available immediately for all members. Free public availability of the new features is scheduled for early 2008.
