ZigBee's potential still unclear

19 March 2008 News

ZigBee, the formal network, security, application-framework, and application-profile layer overlay on top of the 802.15.4 PHY (physical) and MAC (media-access-control) layers used in low-power wireless mesh networks, continues to evolve with its potential still unclear, reports In-Stat. Currently, ZigBee technology targets building automation, industrial, medical, home automation, asset management, HVAC and other monitoring applications, the high-tech market research firm says. More applications will be invented as programmers acquire more understanding of the technology.

"Within the market, there are different philosophies between chipset manufacturers and their approaches," says Brian O'Rourke, In-Stat analyst. "A company like Jennic sees the technology as an application-enabler, focusing on giving its clients low-cost tool kits and providing its ZigBee software stack for free for customers who choose to build with their components. Ember on the other hand, allows its co-processor chipset, the EM-250, as an add-on for a customer that has application-specific MCUs."

Recent research by In-Stat found the following:

* Total ZigBee/802.15.4 node and chipset units will reach 120 million in 2011, up from 5 million in 2006.

* The ZigBee Pro feature set released to members in October 2007 includes network scalability, fragmentation, frequency agility, automated device address management, group addressing, wireless commissioning and centralised data collection.

* There is a surge in interest in ZigBee technology for Automated Meter Infrastructure.

* Adoption in consumer electronics is expected to be low because of competing technologies.
