Worst suspicions contirmed: The terrible security of internet routers Here’s the latest IDT security nightmare: All of the wireless routers through which most loT traffic passes are probably vulnerable to botnets and other kinds of security breaches. That’s the conclusion of researchers at Fraunhofer FKIE in Germany who analyzed 127 different routers sold by seven…

5 tips for designing with embedded antennas
Designing an antenna into a wireless embedded or IoT device requires special care to maximize performance.
IoT: How 5G differs from LTE
5G extends its scope beyond consumer only to many new vertical and enterprise markets. Thanks to its flexibility and improved performance, 5G opens the door to many industrial applications. When researchers and engineers began developing 5G in 2012, they began to look at use cases. The primary motivation for launching a new generation of wireless…
How to improve 5G coverage and capacity
The laws of physics work against RF engineers, forcing design tradeoffs in mmWave systems. Beam steering, frequency reuse, and greater spectral efficiency can help.
5G radios increase emphasis on compliance testing
Compared to 4G and previous generations, 5G’s mmWave frequencies and tight integration increase the complexity of both performance and regulator compliance testing.
Open RAN functional splits, explained
Open radio access networks offer the option of placing network functions in different places along the signal path. That option, called a functional split, lets network engineers optimize performance and make tradeoffs.

Battery breakthrough fatigue For some cheap thrills, try Googling the words “battery breakthrough.” You’ll be presented with page after page of articles breathlessly chronicling one research result after another in energy storage. But you might wonder why, with so many earth-shattering developments, electric vehicles can’t travel 1,000 miles before needing a recharge. The reason: It…

Why lithium batteries won’t fill up landfills Consumers with an inclination toward sustainability have been bummed out over recent revelations that most of the plastics they have carefully separated, washed, and placed in recycling bins typically end up in the local dump. So it may come as good news that dead lithium batteries are increasingly…
