Learn the basics of how to use RF over fiber. You have many options.
RF over fiber: overcoming an inherent transmission-line problem, part 1
Optical fiber can carry analog RF signals from antenna to receiver with far less loss than coaxial cables.
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.
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.
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…
Optical networks move to metro 800G and long haul 400G
Ever increasing data demands push optical networks to transport data at faster and faster rates. Modulation and baud rate affect the distances that optical signals can travel.
How cloud principles impact 5G
As part of the internet, “the cloud” core principles have significantly changed how software is developed and deployed. The principles of virtual machines and containers have impacted 5G’s system architecture. Here’s how.
Customize private 5G networks for application requirements
5G private networks show potential for a wide range of diverse applications. Engineers can implement features to address the requirements of markets such as manufacturing and non-terrestrial networks.
Synchronizing 5G networks brings timing challenges
Frequency synchronization in the radio access network (RAN) minimizes disturbances at the air interface, ensures mobile handover between radio base stations, and fulfills legal and regulatory requirements associated with a frequency license.
