Spirent’s Wi-Fi test service lets you run a battery of performance and precertification tests for routers, access points, or IoT devices. I recently replaced a failed old dehumidifier. Like so many devices, the new unit has connectivity, which is great because now I don’t have to go downstairs to check if the bucket is full.…

BroadWave Technologies announced a 300-Watt fixed attenuator series designed for wireless applications. These attenuators reduce the amount of power delivered in a transmission line without introducing much noise or distortion. Model series 352-023-XXX is a 50-Ohm fixed attenuator with an operating frequency range of DC to 2400 MHz. Standard attenuation values are 3, 6, 10,…

Part 1 explains who originated massive MIMO and how it works IEEE Fellow Thomas Marzetta is well known for originating the 5G massive MIMO (multiple-input multiple-output) technology in 2006, which telecom experts consider to be one of the cornerstones of 5G wireless communications. This technology uses many small, individually controlled, low-power antennas to directly beam…

Rohde & Schwarz has updated software for its vector-signal generator and spectrum analyzer to perform measurements for signals specified in 3GPP Release 17.

Remcom’s XFdid electromagnetic simulation software’s schematic editor now simulates diplex matched antennas.

Wireless infrastructure company Ubiquia puts mmWave repeaters on top of streetlights, which can bring high-speed connectivity to urban areas and town centers.

Model 251-088-030 is a 50 Ohm directional coupler that covers a 500 – 2000 MHz frequency range and features a 30 dB coupling value. The frequency sensitivity is ± 0.75 dB maximum, insertion loss is 0.4 dB maximum, and directivity is 20 dB minimum. Maximum VSWR is 1.25:1, RF input power is 50 Watts average…

The QPB9378 from Qorvo covers 5G’s mid band, seen as the sweet spot for range and bandwidth.

In a video interview, Harrison Osbourn explains that he handle the CEO-level functions while Tom Lane takes over as president.

The u-blox SARA-R500E embedded eSIM lets IoT devices connect to cellular networks without the need for a separate SIM card and supporting hardware, thus saving board space.
