Low-Power Wireless Networking for IoT

LinkedIn Lynda.com has rolled out a new IoT foundations course series in Internet of Things (IoT). The very first course released in April is IoT Foundations: Low-Power Wireless Networking, which covers the increasingly important and fundamental  topics in the IoT. This course is available at this link.

The course contents are self-contained with a carefully designed outline suitable for a wide audience. No matter you are a business strategist, product manager, developer, consultant, engineer, researcher, or post-secondary student, you probably will find something useful in the course.

Here is the course description:

The Internet of Things (IoT) has been significantly driven by the increasing number of networked devices with ubiquitous wireless connectivity. Low-power wireless networking is one of the most important connectivity technologies required by today’s IoT systems, ranging from smart home appliances to smart city systems. In this course, explore the key technologies and foundations of low-power wireless networking for IoT.

Ryan Hu begins by introducing wireless networking for IoT, and going over the basics of wireless communication and wireless networking. Next, he presents and compares the underlying wireless networking technologies in terms of system architectures, communication paradigms, performance, and use cases. Then, he explains how to integrate various networking technologies into an IoT system. To wrap up, Ryan discusses the use of low-power wireless networking in a typical lighting control system for both smart home and smart city environments.

 

News: ARM Adopts ubisys ZigBee 3.0 Technology for Its Cordio Radio IP

“Ubisys’ technology complements ARM IP to enable ultra-low-power, secure and scalable wireless solutions with a range of connectivity options,” said Bob Morris, vice president of marketing, Wireless Business Unit, ARM. “The world of IoT demands choice so products can be fine-tuned to the applications they are enabling. Ubisys’ ZigBee 3.0 solution, used alongside the ARM Cordio platform, delivers the range of connectivity that device developers are looking for.”

“We are extremely excited to partner with ARM in order to enable world-class ZigBee 3.0 solutions on platforms based on ARM processor cores, the Cordio radio IP solution for 802.15.4 and ubisys’ leading ZigBee stack,” said Dr. Arasch Honarbacht, managing director of ubisys. Honarbacht, who is also Vice Chairman of the ZigBee PRO Core Stack Working Group and elected voting member of the ZigBee PRO Technical Steering Committee within the ZigBee Alliance, added, “ZigBee 3.0 is the premier choice for creating interoperable, secure, scalable, reliable, low-power mesh networks for the IoT. Ubisys, the first company to successfully certify ZigBee 3.0 products, is the technology leader in this area. We are fully committed to making this partnership a roaring success and delivering an outstanding solution to the market.”

The ZigBee stack for Cordio is based on the same ubisys ZigBee PRO 2015 and Green Power implementation, which was awarded ‘Golden Unit’ designation by the ZigBee Alliance a year ago and has allowed ubisys to spearhead ZigBee 3.0 product certifications with 12 certified ZigBee 3.0 products so far.

In addition to core stack features, the comprehensive ubisys solution also includes higher-level software components for gateway-grade devices, for example the ubisys Smart Facility Service, ZigBee Gateway Service, Over-the-Air Upgrade Service and JavaScript Host. Adapters to global smart home frameworks like Apple HomeKit and Amazon Smart Home Skills, based on the Smart Facility Service, will be available as further building blocks for turnkey home hub solutions.
