5G base stations rely on phased arrays to steer signals and increase data rates. Beam steering circuits, however, consume power. Using waveguides could reduce energy consumption in base stations. Waveguides are physical structures that direct electromagnetic waves from one point to another, confining energy within specific boundaries to control propagation, direction, and mode. While waveguide…

5G is much more than cell phones. IoT devices, medical devices, and industrial devices can connect to networks using technologies such as TDD, network slicing, and beamforming. 5G New Radio (NR) made its long-awaited commercial debut in late 2018. Offering significantly faster speeds and greater capacity compared to 4G Long Term Evolution (LTE), 5G NR…

Millimeter-wave signals used in 5G networks provide wide bandwidth and high data rates. Signal losses, both over the air and through interconnects, bring design challenges.

Fixed-wireless access is a special use case of enhanced mobile broadband, one of the three use cases specified for 5G. FWA brings different challenges for deployment than eMBB.

Signals in the mmWave range require extra care and more expensive components than at sub-6 GHz frequencies.

5G brought passive intermodulation problems into the spotlight. Now it’s up to engineers and technicians to identify and mitigate signal degradation to minimize dropped calls and other issues. A loose connection; a metal roof; power lines. Even a rusty bolt. It’s estimated that mobile operators will spend $1.1 trillion on capital expenditure between 2020 and…

MediaTek’s Dimensity 7200 modem chipset offers much for consumers, but what of the engineers who design with it?

AI techniques can overcome nonlinear problems by extracting patterns automatically and efficiently.

Mediatek’s Dimensity 8200 CPU/GPU/modem features eight CPU cores, six GPU cores, and LPDDR5 memory to boost gaming and video.

Design the Telit LN920A13-WW data card into IoT and fixed-access devices.
