Dec 20 - DAY 4: ZigBee in Depth Part 2
Continuing Education Center 12/20/2012
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
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
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
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
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
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
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.
General Motors is putting an off-road twist on hydrogen fuel cell technology with an imposing new pickup demonstrator called the Chevrolet Colorado ZH2.
Fine powder printing of industry-standard metal and ceramic powders with a grain size of less than 10 microns is now available from industrial 3D printer maker ExOne for its Innovent printer.
At ARM TechCon 2016, CEO Simon Segars will discuss how he sees billions of devices scaling to trillions as IoT applications proliferate. We know it’s happening. How do we prepare?
The term “autopilot” is now at the heart of a growing debate between Tesla Motors Inc. and Germany’s Federal Motor Transport Authority.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
