The upstream linear burst-mode transimpedance amplifier is the first to support 50 Gb/sec NRZ and 100 Gb/sec PAM4. They could drastically increase internet connection speeds and 5G infrastructure.
RF over fiber: overcoming an inherent transmission-line problem, part 2
Learn the basics of how to use RF over fiber. You have many options.
How to safeguard cellular base stations from five electrical hazards
Circuit-protection components such as fuses and TVS diodes protect power and data circuits from damage. Here’s where and how to insert them into your circuits.
Lens antennas focus multiple wireless beams
Using refraction instead of reflection or phased arrays, MatSing has created antennas that produce multiple beams. If you’ve recently attended a game at AT&T Stadium in Dallas, Allegiant Stadium in Las Vegas, Amalie Arena in Tampa, or even attended a presidential inaugural and used your phone, then you’ve probably used an antenna by MatSing. The…
Data centers get a boost from connectors and cables
Demands for bandwidth-intensive, data-driven services are fueling a rise in compute, data storage, and networking capabilities. These rises put pressure on connectors and cable to deliver data at higher speeds with better signals and less heat.
Can Wi-Fi 6E really share spectrum with incumbents?
Learn how Wi-Fi 6E standard-power transmitters must navigate around public safety and wireless backhaul signals in this video interview with Federated Wireless CTO Kurt Schaubach. For over two years, we’ve been hearing about how Wi-Fi 6E adds 1200 MHz of needed bandwidth to meet growing needs. The so-called “6 GHz band,” which covers 5.925 to…
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.
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.
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…
mmWave repeaters bring high data rates to city streets
Wireless infrastructure company Ubiquia puts mmWave repeaters on top of streetlights, which can bring high-speed connectivity to urban areas and town centers.
