5G Insights On Demand
January - February 2020
Essential 5G Field Tests
Presented by: Rolland Zhang
5G technologies provide dramatic network speed improvement and super-fast connection time. 5G brings new physical layer technologies like beamforming, massive MIMO, and mmWave transmissions. You need to learn new ways to make network measurements to deploy these new physical layers and achieve designed performances.
Key learning highlights
- What is new in the 5G physical layer
- Understanding 5G network field tests
- Addressing 5G deployment using FieldFox
Modulation Distortion: How to Make High-Accuracy EVM Measurements for 5G
Presented by: Sam Kusano
Power amplifiers (PAs) play a critical role in RF transmission quality. PA designers need to maximize linearity while maintaining high efficiency. This balance is challenging to achieve with the wide signal bandwidths in the millimeter-wave (mmWave) spectrum for 5G New Radio.
To measure the nonlinearity of a PA under a modulated stimulus condition, the industry uses error vector magnitude (EVM) as a figure of merit (FOM) for in-band characteristics and adjacent channel power ratio (ACPR) for out-of-band characteristics. This webinar introduces an innovative method to characterize the nonlinear distortion of a device under a wideband modulated signal called modulation distortion.
- Key challenges for testing EVM of wideband PAs
- Modulation distortion basics
- How to improve EVM measurement accuracy
5G Non-Terrestrial Networks — Overview & Focus on Satellite Link Simulation
Presented by: Jani Tolonen
3GPP Release 17 includes 5G non-terrestrial networks (NTN). These networks are essential to offload traffic from terrestrial cellular networks and increase network coverage to hard-to-reach areas and isolated nodes such as airplanes and oil drilling platforms. Research and development efforts are in full swing, with deployment expected in 2021.
Join us in this webinar to understand the main use cases for 5G NTN. Learn about the different service implementations and satellite communication link simulation.
Key learnings:
- 5G NTN definitions and timeline for standardization
- Main use cases for 5G NTN
- How to overcome 5G NTN testing challenges, such as long delays and high Doppler shifts
