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…

Millimeter wave signals provide wider bandwidths and higher data rates than signals at lower frequencies. Take a look at the overall signal chain that falls between the antenna and the digital baseband. 5G new radio (5G NR) adds mmWave frequencies to cellular devices and networks. With that comes RF-to-baseband signal chains and components not needed…

Learn the basics about SmartNICs, their design, and why they’ll be a crucial element in future networks.

Return loss happens when transmitted energy reflects back to its source. Designers must pay close attention to optical return loss (ORL), an important metric in an optical network. ORL is defined as return loss for the entire optical fiber under test, which includes fiber backscatter and reflections relative to the source pulse. This ORL metric…

Yagi antennas have long been popular as beam antennas for amateur radio. Here’s how they work.

In a video interview, Wi-Fi test veteran Fanny Mlinarsky updates us on Wi-Fi 7’s new features and how they work.

Antennas come in a broad range of sizes, styles, and configurations to meet frequency, bandwidth, directivity, and many other objectives; the PIGA and Yagi antenna are two different yet widely used versions.

Antennas come in abroad range of sizes, styles, and configurations to meet frequency, bandwidth, directivity, and many other objectives; the PIGA and Yagi antennas are rather different yet widely used versions. With a few highly specialized exceptions, all antennas in general use—ranging from tiny ones in wearables to huge broadcast-transmitter designs — are extensions, enhancements,…

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

Communication systems such as 5G that operate at today’s wide bandwidths and high orders of modulation need to maintain proper SNR and EMV. Path loss and phase noise can get in the way.
