Engineers developing products for the IoT need to plan security measures that grow more sophisticated over time to thwart attackers who get better at wreaking havoc. Lars Lydersen, Silicon Labs Skepticism about the Internet of Things (IoT) security seems to be high. Ironically, for many industries, the key to not being hacked is simply do […]

Everything you thought you knew about IoT security is wrong
Leland Teschler, Executive Editor Listen to the advice being given for securing IoT devices and you are likely to be told that the level of security should be scaled to meet the probable threats. Internet-connected home thermostats, for example, should be designed to prevent compromise by hobbyists and serious hackers. But the usual recommendation is […]
Gallery: Inside the Dialog Semiconductor SmartBond Wireless Microcontroller Tech Tour
Dialog Semiconductor is conducting a series of one-day free seminars around the country covering its offerings in Bluetooth low energy that includes hands-on training as well as presentations on the newest version of the Bluetooth spec, 5.1. One attraction of the event is that attendees get two free Bluetooth low energy development kits worth more […]
Smaller, cheaper, better: Microsatellites
by Rudy Ramos, Mouser Electronics In 1957, the Soviet Union launched Sputnik 1. The satellite was just 50cm wide. Today’s most massive unmanned spacecraft, the bus-sized Hubble telescope, weighs 11 tons. However, in recent decades, practical satellites have shrunk once more to Sputnik dimensions. Several factors limit satellite minimum sizes; solar panel area to generate […]

Understanding wireless across the spectrum
Waves are part of our world as both waves in the ocean and radio waves coming in from the Sun’s corona share fundamental properties.[i] Wireless communication was born from the science of waves and how they travel. After more than a hundred years of study, we’ve organized waves into a large electromagnetic spectrum (EM) that […]
The nuts and bolts of verification: Recasting SystemVerilog for Portable Stimulus
by Matthew Ballance, Mentor, a Siemens Business Nuts and bolts. So prosaic, yet so fundamental and essential. They can be reused, mixed-and-matched in endless ways. All those old jars and tins full of leftover nuts, bolts, and screws have saved many trips to the hardware store. Yet, if not for standardized gauge, thread count, and […]
IoT standards: The End Game
by Cees Links, Qorvo Quite regularly I get the question: with all these standards around, what should I choose? Zigbee, Thread, Bluetooth Mesh, or Wi-Fi? Or maybe LoRa? Or is it better to wait for 5G and NB-IoT? Of course, these questions create confusion and slow down the adoption of the Internet of Things (IoT). […]
LoRaWAN security design tips, Part 2: Taking the integrated approach
Part 1 of this two-part series on security design discussed using a stand-alone security chip. Here in Part 2, we’ll cover solutions that use an integrated chip and module, combining security and microcontroller (MCU) functions in a single chip. Integrated chip Cypress’ PSoC 6 MCU single-chip, dual-core architecture comprises the Arm Cortex-M4 and the Arm […]
Considerations for battery-powered designs
How can you make your resume really stand out? This has been the topic of books, articles, class assignments, and blogs for decades. It came up in conversation one day, and a friend of mine had a unique story. I’ve included it below, with some edits. “With so much written on the topic, there is […]
