By Jon Adams Seems like everyone wants to get into enabling the wireless part of the world of wireless sensors. Now there are the DECT (Digital Enhanced Cordless Telecommunications) fans! What’s DECT? It’s a wireless communications technology that’s been around for over 20 years, and today is pretty much used exclusively for cordless home telephones. [...]

By Jon Adams Over a year ago, the US NIST (National Institute of Standards and Technology) added ZigBee wireless technology to its Framework and Roadmap for Smart Grid Interoperability Standards, which defines systems and technologies that are approved for use in the rapidly growing smart grid. Then two months ago, in October, the Association of [...]

By Jon Adams Troy Wolverton at the San Jose Mercury News recently penned a great article on the value of ZigBee for low-rate, battery-friendly communications between devices in most household environments. He even opines that the potential volume for ZigBee-enabled devices could exceed that of Wi-Fi and Bluetooth no small challenge, but there’s some stuff [...]
By Jon Adams There sure are a lot of standards-based wireless communications technologies out there. Do there need to be so many? In the immortal words of Jack Nicholson’s President James Dale, “Can’t we all just… get along?” and pick just one?

By Jon Adams I’m traveling back from the IEEE802 plenary in Atlanta GA and have the opportunity to use the new inflight Wi-Fi service. I’d had a flight on the way out last week where I measured 0.4 sec latency and over 1Mbps throughput. While I’m still awed by the seemingly seamless connectivity that I [...]

Jon Adams Way back in the last century, a plucky band of engineers and visionaries got together under the aegis of a group called IEEE 802.11 to craft a technique to allow computers to share information via wireless networking. At the time, Ethernet was finally becoming established as the network connectivity medium, but already there [...]
