Demystifying 5G – External harmonic mixer vs. spectrum analyzer

How to extend the frequency range of your spectrum analyzer? You can either use external harmonic mixers or invest in a new spectrum analyzer that covers the required frequency range. This video explains the differences between both methods and why a spectrum analyzer has a clear advantage compared to an external harmonic mixer.

Demystifying 5G – Testing the true performance of ADCs

Enhanced mobile broadband (eMBB), one of the 5G use cases, targets wider bandwidths at frequencies in the mmWave range to achieve the promised Gbps experience. This requires new, high-resolution digital-to-analog converters (DACs) and analog-to-digital converters (ADCs), such as the recently launched ADC12DJ3200 from Texas Instruments. They demand highest signal purity for testing their true performance.… Read more »

Demystifying 5G – 5G specification published by Verizon Wireless

In July 2016 Verizon Wireless, the United States tier-1 network operator, published a first set of technical specification for a proprietary 5G wireless communications standard. The standard is based on LTE Release 12 and intended for “fixed wireless access”. This video provides some background information and compares the Verizon Wireless 5G standard with the current… Read more »

Demystifying 5G – Enable mobility in 5G systems

Dual connectivity is the method of choice for (pre-)5G and 5G NR to enable full mobility using LTE as an anchor technology. However, there are quite some differences between the 3GPP-based version of dual connectivity and how (pre-)5G standards are planning to utilize this methodology. In this video we explore the differences between the two.
