I came across an article in Fast Company on a wireless technology standard that I think most people (especially non-techies) have probably never heard of – ZigBee.
ZigBee is a wireless technology that uses significantly less power than WiFi and as a result is ideal for monitoring applications. The application detailed in the Fast Company article was a remote healthcare monitoring solution called AT&T Telehealth, but the technology is also touted for energy management and efficiency, home automation, building automation, and industry automation.
If you are interested in learning more about ZigBee, they have lots of educational information on their web site.
What other uses can you imagine for this technology?
