Dec 20 - DAY 4: ZigBee in Depth Part 2
Continuing Education Center 12/20/2012 216 comments The Operating Details Under each profile is a set of operating protocols for sending set data. We will look at the structure and operation of these. We will also look at how one may use the strong structure of ZigBee to build a proprietary profile, gaining from the advantages of the protocol while providing for your unique communications and control needs.
Dec 19 - DAY 3: ZigBee in Depth Part 1
Continuing Education Center 12/19/2012 225 comments Profiles one of the primary selling points for ZigBee is the guaranteed interoperability between nodes, regardless of who made the equipment. This is assured by the use of profiles that are established by the ZigBee Alliance and are independent of any one manufacturer. We will look at the established profiles and how they operate.
Dec 17 - DAY 1: Executive Overview - What is ZigBee, Anyway?
Continuing Education Center 12/17/2012 280 comments Much is being said about the ZigBee protocol and its promise for low-power and dependable mesh networking, but what does ZigBee entail and what does it mean for a company that is thinking of incorporating it? We will discuss just what the standard and protocol are about, its history, and where it is going.
Dec 6 - DAY 4: 802.15.4 Radio Design Factors
Continuing Education Center 12/6/2012 214 comments This discussion addresses factors that affect radio communications and small radio design. Range, power, and data transfer rate together with physical size, weight, and cost impact design choices. We will speak about link budget, operating frequency, and antenna considerations. The discussion reviews power requirements for typical 802.15.4 radio systems.
Dec 5 - DAY 3: 802.15.4 Radio Protocols & Topology
Continuing Education Center 12/5/2012 213 comments This discussion considers the 802.15.4 communications protocols. We address various operating protocols, taking a look at Zigbee and competing protocols. We also address 802.15.4 radio operating topologies such as star, star-mesh, mesh, and adaptive mesh approaches.
Dec 4 - DAY 2: 802.15.4 Radio Link Modulation
Continuing Education Center 12/4/2012 237 comments This discussion takes as its focus the 802.15.4 standard as it applies to radios operating at 2.4GHz. We consider 802.15.4 modulation, the concept of "chips" and direct spread spectrum modulation, data throughput, and alternate modulation techniques.
Dec 3 - DAY 1: Navigating FCC Regulations
Continuing Education Center 12/3/2012 235 comments Federal Communications Commission rules and regulations are confusing. This discussion helps you to sort out the relevant portions of FCR 47 as it applies to ISM radio for 802.15.4-style data communications. The discussion limits its focus to regulatory matters in the United States.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
