High-speed data challenges physical-layer optics
Calibration is important in the measuring the effectiveness of fiber-optic cables. Fluke fellows Seymour Goldstein and Jeff Gust explain why.
Module adds LTE Cat 4, Wi-Fi, Bluetooth to IoT devices
Quectel Wireless Solutions announces that it has launched its new generation of multi-mode Smart LTE Cat 4 modules, the SC200E series. The SC200E series delivers superior performance in LTE connectivity, multimedia functions, and support for long-lifespan IoT deployments, making it ideal for both industrial and consumer applications including smart POS, payment terminals, industrial handheld devices,…
Engineering at the heart of cellular repeaters
In a video interview with Nextivity CEO Michiel Lotter, EE World looks at the technology behind cellular repeaters that distribute signals over Ethernet cables before rebroadcasting.
Test service brings confidence to Wi-Fi devices, or finds bugs
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.…
Fixed RF attenuator handle 300 W
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,…
Creating 5G massive MIMO: Part 1
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…
5G RF test equipment supports Release 17
Rohde & Schwarz has updated software for its vector-signal generator and spectrum analyzer to perform measurements for signals specified in 3GPP Release 17.
Schematic editor software supports diplex matched antennas
Remcom’s XFdid electromagnetic simulation software’s schematic editor now simulates diplex matched antennas.
Full-brick 500-W supply provides 12 V and up to 42 A
Advanced Energy Industries, Inc. expands its presence in the industrial, robotics, and 5G telecom markets with the launch of the AE Artesyn AIF42 AC/DC converter. The new converter reduces system size, delivers best-in-class 93% efficiency, and enhances reliability by minimizing the need for external components. The AIF42 full brick module is rated for 500 W […]
