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.


Low-energy Bluetooth is formally adopted – News – Linux for Devices

Bluetooth. low energy

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.”


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.”
