EVs are getting more affordable worldwide โ except in the U.S.
The U.S. is impaired by a lack of supportive policy and subsidies, the unavailability of affordable Chinese models, and a preference for big cars.

While the long-term effects of AI have yet to be established, a new study reveals that the technology can seriously impair brain performance in a relatively short period.
A comprehensive guide to error vector magnitude (EVM), the primary metric for quantifying modulation accuracy in Wi-Fi, LTE, and 5G NR systems. What Attendees will Learn What error vector magnitude is and how it is calculated โ Understand EVM as the distance between ideal and measured constellation points, learn the difference between peak and RMS normalization, and see how EVM is expressed in both percentage and decibel formats. How digital modulation works and why it matters โ Explore the fundamentals of ASK, FSK, PSK, APSK, and QAM modulation schemes, and understand why higher modulation orders increase throughput, while also demanding greater accuracy in signal transmission and reception. What causes degraded EVM in real-world systems โ Examine the four main categories of EVM contributors: amplitude effects (compression, noise, frequency response), phase effects (phase noise), I/Q imperfections (gain imbalance, quadrature error), and configuration issues. How to diagnose modulation impairments using constellation diagrams โ Learn how visual inspection of constellation diagrams can identify phase noise, amplifier compression, noise, in-band spurious signals, and I/Q modulator imperfections as root causes of degraded EVM.
