WiFi Rides 900 MHz, Attacking Zigbee | EE Times via @eetimes
SAN JOSE, Calif. — WiFi is preparing to ride 900 MHz spectrum bands in an effort to compete in cost and range with a fragmented set of options in home and building automation and the Internet of Things. Chips and systems using the upcoming IEEE 802.11ah standard are expected to hit the market starting in 2015. The effort makes sense for the standard that is the most broadly used form of wireless local-area networking. However, it represents a reach for a sector already embracing 60 GHz for in-room multimedia and is no slamdunk against a dozen well-established options already optimized for building and home automation such as Zigbee and Z-wave . A first vote on the .11ah standard could come as early as the end of September, although a final standard is not expected until January 2016. That makes 2014 the time frame for development of new silicon for end nodes and access poi...
