Is Li-Fi “To Be” or “Not To Be”? Part 1: Context
Optical wireless communications in the form of “Li-Fi” is a technical alternative to RF-based Wi-Fi with distinct strengths and weaknesses. You are undoubtedly familiar with Wi-Fi – a contraction of “Wireless Fidelity”– which has become the de facto standard for wireless connectivity between the Internet or local area networks and PCs, smartphones, countless appliances, gadgets, […]
Assessing safety and performance in connected vehicles
Testing and certification for vehicle and infrastructure devices ensure software and systems will perform as advertised. Ralph Buckingham, Wayne Stewart, Intertek As consumers look to connect their cars, the technology behind these vehicles and their various connected components is evolving far more quickly than standards governing them can change. Consequently, manufacturers and developers sometimes lack […]
Delivering advanced face recognition capabilities at the edge
By Rick Bye, Senior Product Marketing Manager, NXP Using face recognition for access control The COVID-19 pandemic highlights concerns over how many different surfaces we often touch during a typical day. For example, everyone entering a secured building, such as a workplace or after-hours hotel entrance, touches access control keypads that present an ideal surface […]
What is Wi-Fi HaLow? Players and future
Part 1 focused on HaLow technology; this part will explore who the major players are and discuss the future of the technology. Who are the major HaLow players? A few silicon startups are taking the lead in Wi-Fi HaLow rather than the traditional major chipmakers. They include Morse Micro, Newracom, Methods2Business (an IP provider), and […]
What is Wi-Fi HaLow? Part 1
In the first part of this two-part series, we focus on Wi-Fi HaLow technology. Part two will explore who the major players are and discuss the future of the technology. What is HaLow? In 2017 the wireless networking standard IEEE 802.11ah, also called Wi-Fi HaLow (pronounced “HAY-Low”), was released. HaLow uses the 900 MHz industrial, […]
Technical challenges of automated vehicles
Automated vehicles, also called self-driving cars or autonomous vehicles, are slowly emerging. It’s not an “all or nothing” situation. Features and technologies needed for automated driving are being developed incrementally, with some already in use. This FAQ looks at some of the technologies needed for automated driving, including various levels of “driver support features” versus […]
The role of ADAS sensors in automotive design
Advanced Driver Assistance Systems (ADAS) are intended to prevent deaths and injuries by reducing accidents. Exemplary ADAS applications include: pedestrian detection/avoidance, lane departure warning/correction; traffic sign recognition; automatic emergency braking, and; blind-spot detection. This FAQ starts with an overview of the “levels of driving automation” and its relation to ADAS. It then reviews the role […]
What are ASILs and how do they work?
Automotive Safety Integrity Levels (ASILs) are a risk classification framework based on the ISO 26262 standard for Functional Safety for Road Vehicles. ISO 26262 is the adaptation of the IEC 61508 standards to address the specific needs of electrical or electronic (E/E) systems within road vehicles. This FAQ reviews the current status of the ASIL […]
