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.
Andreas Roessler — Rohde & Schwarz In this presentation test and measurement aspects will be discussed, challenges identified and status of current solutions being presented.
Dr. Joy Laskar — Centric Technologies In this presentation, we will begin with an overview on the need and applications of millimeter wave with multi-gigabit bandwidths (>3.5Gbps). Next, we will discuss the key design and test considerations for a single chip CMOS mmW system on a chip, including full radio and baseband functionality.
Dr. Vuk Marojevic – Virginia Tech This talk will present Virginia Tech’s results on LTE coexistence with Radar in the 3.5 GHz band, obtained at Wallops Island in August 2013. These test results provide an important stepping stone towards secondary usage of federal spectrum, encouraging further research and innovation in this area.
In this panel session, we will hear from the industry’s leading OTA users and advocates their perspectives on the strategic role that OTA plays, the latest in OTA measurement techniques, and where and when OTA ideally fits within the mobile device design cycle.
Derek Skousen — Bluetest | Thorsten Hertel — Rohde & Schwarz This joint presentation will provide a high-level overview of over-the-air (OTA) testing now and into the future including the use of dynamic multipath environments. We will also discuss multiple-input multiple-output (MIMO) OTA test methodologies, how they are being addressed by the standard’s organisations, and… Read more »
