by Kevin Tang, Sr. Director, Strategic Business Development, ON Semiconductor Market demand for higher bandwidth broadband services is on the rise, thanks to the rapid growth of the internet, social media, and online streaming services, especially as the number of broadband users per household increases and the trend of cord-cutting continues to accelerate. Across urban, […]
Who is winning the LPWAN race? Part 2
Continues from Part 1 FAQ on Low-Power Wide Area Network (LPWAN) technology & implementation 6. What are some of the LPWAN design considerations? There are many criteria a business can consider when trying to decide on the best LPWAN solution. For example, how quickly do you need the IoT device to transfer the data, how […]
Who is winning the LPWAN race? Part 1
A two-part tutorial series on Low-Power Wide Area Network (LPWAN) technology & implementation. Low-power wide-area networks have continued gaining momentum over the last few years, propelled by IoT growth and sensor ubiquity. In this article, we will answer the basic, frequently asked questions, and offer insights on the implementation strategy. There are different abbreviations for […]
Teardown: A simple pulse oximeter for home healthcare
If you’re recovering from a respiratory problem, chances are you may have had your oxygen levels checked with a pulse oximeter. Pulse oximetry is the non-invasive measurement of the oxygen saturation (SpO2). Oxygen saturation is defined as the amount of oxygen dissolved in blood, based on the detection of Hemoglobin, Hb, and Deoxyhemoglobin, HbO2. The […]
Starting an HMI design? Here are four things to watch
The human-machine interface (HMI) is growing in consumer as well as industrial applications ranging from lighting to HVAC to digital signage. There are many HMI solutions, including the ones that use buttons, sliders, wheels, capacitive proximity sensing, and even human voice. There are tools and kits available that simplify the fine-tuning of HMI designs. What’s […]
Billions of reasons to build a trusted safe and secure IoT world
by Marc Vauclair, Senior Security System Architect, NXP Semiconductors The IoT (Internet of Things) devices we use in our homes, cars, mobile communication devices, and payment systems are also becoming increasingly accessible across healthcare and industrial domains. These billions of connected devices – some forecast 75 billion IoT devices by 2025 — will be a […]
AI-assisted screening for COVID-19 using CT images
Although COVID-19 tests are one means to determine infection, the rapid spread of the disease has created a shortage of test kits and a tight supply of reagents that are used to create test kits. Symptoms are another indication, but some of the infected show very mild or no symptoms. Another method leading to a […]
Breaking BLE — Vulnerabilities in pairing protocols leave Bluetooth devices open for attack
Despite built-in safe-guards, Bluetooth Low Energy IoT devices are vulnerable to hacks when they communicate over the air. Here are the basics of the problem. Leland Teschler, Executive Editor If you eyeball internet-of-things items ranging from smart ac plugs to motion sensors you typically find connectivity via the Bluetooth Low Energy (BLE) standard. A lot […]
Developing connected medical devices for the IoT
Super-small radio SoCs are being paired with innovative battery technologies to bring inexpensive medical electronics online. Adrie Van Meijeren, Low Power Connectivity • Dialog Semiconductor The Internet of Things (IoT) has disrupted many industries in short order. However, when it comes to adopting the IoT, the medical and pharmaceutical space has largely been held back. […]
How to test USB4 designs
Designers must look at and characterize the entire Type-C ecosystem when testing USB4 designs. Jit Lim • Keysight Technologies The USB Type-C connector has received significant adoption with ubiquitous standards like USB, DP, and Thunderbolt. The next-generation variant of USB is USB4. USB4 will transmit and receive on all four lanes of the Type-C connector […]
