Continua picks ZigBee, Bluetooth LE (2009) for health devices, sensors
The two wireless technology standards are targeted to support mobile and fixed location devices as defined by the next iteration of the Continua Health Alliance Design Guidelines. The alliance has selected Bluetooth low energy wireless technology (pending finalization of the specification) to enable low power mobile devices such as activity monitors and heart rate sensors to be used to monitor a user?s health and fitness levels. Additionally, Continua has selected ZigBee Health Care technology for low power sensors that can be networked in a variety of settings, and utilized in devices such as motion detectors and bed pressure sensors to enhance the daily living of those who require assistance aging independently.
?ZigBee standard enables powerful new wireless applications for safety, security, and control, ranging from smart energy to home automation and medical care to advanced remote control.
Bluetooth low energy versus ZigBee

I've touched on this topic before outside of the blog, but a recent comment made me think that it could be appropriate to bring it up again. People enjoy some controversy, so what's better than putting different standards up against each other? I'll try to explain the differences and explain why BLE and ZigBee don't really step on each other's toes in my opinion:
There will surely be some overlap in application areas, as there is always some tendency to try to broaden the scope of standards, but overall Bluetooth low energy and ZigBee target different areas. They each have their own strengths and weaknesses. BLE will be able to communicate with billions of Bluetooth devices, but does not support mesh. ZigBee can cover large areas, but is not so well suited to ad-hoc networking and requires powered routers.

Research and Markets: Bluetooth Low Energy Forecast to Dominate Wireless Sensor Network Market says Q2 2010 Report
West Technology Research Solutions analyst Kirsten West, quoted by our sister publication eWEEK, said "Bluetooth low energy will be a significant contributor to the overall wireless sensor network market, representing nearly half of all shipments in 2015. The advantage to this new protocol is that it is totally optimized for low power battery operation."
?Bluetooth Low Energy is designed to compete with protocols like ZigBee in applications which require infrequent and short bursts of data communication. The advantage to this new protocol is that it is totally optimized for low power battery operation.?
By 2014, analysts project, consumers will buy over 200 million wireless body sensors every year! Every one of them can communicate best with Bluetooth low energy communication technology!
Ultra Low Power Wireless Quarter
Tiny Sensors Run Forever (Almost)
Developers of ZigBee, a specification for building large networks of low-power radio transmitters, expect the first set of consumer products incorporating the technology to hit the market as early as the fourth quarter of this year.
"The great thing with this technology is it's slowly going to surround you -- whether you know it or not," said Bob Heile, chairman of the ZigBee Alliance, which includes more than 175 members, including large multinationals like Motorola, Philips and Samsung.
*Upcoming products, including several slated to be unveiled at the alliance's upcoming conference in Chicago this month, are *mostly tailored to home security. But backers of the technology expect it will eventually be deployed much more broadly, for uses like landscaping, automated meter reading, and home lighting systems.
?Low-power sensing and monitoring is a core competency of ZigBee and we are excited to help Continua build its technology roadmap and help expand the telehealth industry ecosystem,? said Dr. Robert F. Heile, chairman, ZigBee Alliance. ?ZigBee Health Care gives care professionals and consumers the ability to connect an almost unlimited number of monitoring devices with ease while maintaining privacy.?
