Welcome to the third installment of the 5G Technology World quiz. So, you think you know 5G? The quizzes, sponsored by Keysight Technologies, will highlight a different aspect of 5G each month through December 2020. The quiz is interactive; it will tell you which questions you answered correctly or incorrectly. Each month, we'll select five people who correctly answered all the answers and give them a "shout out" on the leader board. To get a shout out, you'll need to enter your email address, a username, and select your country. The leader board is open to U.S residents only.

Did you not correctly answer all questions? That's OK. 5G is new to many of us. You can always read the source material from the provided link. Good luck. We look forward to seeing you on the leader board.

With the rise of the open radio-access networks (RANs), equipment from multiple vendors can for the first time be implemented in the same -RAN. Using software running on commercial hardware will let network operators pick and choose how to virtualize their networks, improve RAN innovation, enhance flexibility, and reduce costs by disaggregating proprietary baseband units into radio units, distribution units, and centralized units. Open RANs will add complexity to 5G networks, but the advantages may outweigh the risks.

This month's quiz comes from "O-RAN Next-Generation Fronthaul Conformance," a white paper from Keysight Technologies.
