Cold starts, hot power markets, and great expectations Recent cold spells across the United States have shifted the focus from “range anxiety” in electric vehicles (EVs) to concerns about their performance in cold…how they start, and how far they can go. Buzzworthy? Apparently. Newsworthy? Maybe, but it’s not new news. Reflecting on a youthful […]
December 2023 EV Engineering Supplement: Reducing range anxiety
How automakers are increasing EV battery voltages In this supplement, you can read about the following: How silicon-carbide technology can address high-voltage EV challenges? Sales of new electric vehicles (EVs) in the US exceeded five percent of the total market for the first time in 2022, joining 18 other countries worldwide that have surpassed the […]
The promise of AI for engineering leaders
The promise of AI is plain and simple: greater product development efficiency and faster time to market. Products are becoming more complex, yet engineering teams don’t have more time. Using historical or current engineering test data to train self-learning models, today’s visionary engineering leaders are reducing testing time and simulations for products with even the […]
Why O-RAN sync monitoring needs AI/ML
As Open RAN deployments gather pace and accurate timing, synchronization has emerged as a critical step toward consistent performance. It is a complex task, with devices requiring time synchronization to UTC reference via IEEE PTP/SyncE-based boundary clocks, slave clocks, PRTC clocks with GNSS receivers, as well as accurate, real-time monitoring in support of customer SLAs.…
What you need to know about potentiometers
From analog volume controls to precision measurement devices, potentiometers offer engineers a reliable means of achieving control and precision in electrical systems. Commonly referred to as “pots,” these devices are essentially resistors featuring a mechanical adjustment mechanism that allows for manual change of their resistance. Their basic principles and concept date to the 1800s with […]
August 2023 Issue: Automotive & Transportation Electronics
In this issue Smarter, safer, cheaper: how Ethernet will enable the car of the future The implementation of Ethernet as a universal standard throughout the automotive industry can optimize vehicle performance by reducing the number of electronic control units (ECUs) and associated wiring, thus enabling a smarter, cheaper, and safer future car. Zonal E/E will […]
What are the critical measurements in satellite uplinks and downlinks?
Noise measurement, LO substitution, receiver stress testing, power measurement, CCDF and PAPR characterization, and antenna-pattern measurement play critical roles in link budget, bit-error rate, and SNR requirements.
Open RAN networks pass the time
Network elements must meet certain frequency, phase, and time requirements to ensure proper end-to-end network operation. Synchronization architectures defined by the O-RAN alliance dictate how Open RAN equipment can meet these requirements. Open RAN continues to attract interest from service providers looking to reduce cost, improve competition, and drive technology innovation. The desire for a…
IoT devices in private 5G networks bring new verification tests
With private networks connecting to many IoT devices, testing the device’s user interface requires updating test processes. Many IoT use cases rely on private 5G networks because they offer greater network control, better security, more reliable performance, and dedicated coverage and capacity as opposed to using a public network. With these advantages, private networks play…
