In this video we explain how to use a scrambled bit sequence as payload in form of a data list for 5G waveform candidates, such as FBMC, UFMC or GFDM, using the R&S®SMW200A vector signal generator.
mmWave frequencies provide quite some challenges, including a much higher Doppler shift compared to sub-6 GHz frequencies when targeting higher speeds. This puts some significant challenges on system design to enable full mobility. In this video we explore the fundamentals for mobility in a cellular system and show how (pre-)5G and 5G systems eventually tackle… Read more »
This video demonstrates how to test a power amplifier that operates at 28 GHz. We use a downlink signal characteristic based on a waveform that follows the Verizon Wireless 5G specification.
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.
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 »
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 »
In this video we explore how to set up Rohde & Schwarz signal generators and spectrum analyzers to characterize a 5G power amplifier using 5G waveform candidates, such as FBMC, UFMC or GFDM.
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.
