Published2019.10.17 07:01Wi-Fi 6 PA/FEM Test Reference Architecture Announced
Extending VST bandwidth, accuracy, and measurement speed
On the 16th, National Instruments (NI) announced a Wi-Fi 6 front-end test reference architecture for testing Wi-Fi 6 Power Amplifiers (PAs) and Front-End Modules (FEMs) operating in frequency bands above 6 GHz.

The NI Wi-Fi 6 Frontend Test Reference Architecture integrates RF signal generators up to 12 GHz and RF signal analyzers with an instantaneous bandwidth of 1 GHz to extend Wi-Fi test coverage to a new band between 6 and 7.125 GHz. This extends the high bandwidth, accuracy, and fast measurement speeds of the Vector Signal Transceiver (VST).
The new solution provides excellent linearity, low noise, and high dynamic range during PA/FEM characterization and verification to verify the performance of Wi-Fi 6 1024-QAM. In addition, dynamic EVM measurement was simplified while the speed of FPGA-based power level measurement was increased.
"VST's wide frequency range and large instantaneous bandwidth are important for delivering stable data across the entire Wi-Fi frequency band in a short time while embracing new bandwidths," said Stefanie Breyer, Vice President of Product Planning at NI. "By selecting NI's software-defined platform-based testers, you can respond to the latest wireless communication standards."

Three 5G NR Challenges That Can Be Solved Right Now
Korea's 5G is preparing for a step-by-step upgrade to meet market demands. This represents a leap from the 3.5GHz frequency band, known as 4.5G since its initial launch in 2018, to true 5G via 28GHz. By simultaneously utilizing the 3.5GHz band and existing LTE networks to bring the entire nation within 5G coverage, the NSA (Non Stand Alone) designation is expected to be removed after 2020. However, the introduction of 28GHz is adding further challenges to the already complex 5G development landscape, placing additional tasks before development engineers. This technical article addresses the challenges of 5G New Radio as presented by Keysight and discusses methods for resolving the current issues at hand.

SK Telecom First Applies AI-Based Network Operations at Gwanghwamun K-Pop Concert
SK Telecom announced that it applied an AI-based network operation system for the first time at a large-scale K-pop concert held in the Gwanghwamun area of Seoul on March 21st, managing communication quality throughout the event. Mobile data usage during the three hours before and after the concert reached 12.15TB, approximately doubling compared to the same time slot the previous weekend. SK Telecom monitored traffic using the AI system 'A-One' in five-minute and 50-meter units to respond to potential overload situations, while also operating temporary communication facilities and on-site personnel in parallel. This case is interpreted as confirmation of the practical applicability of AI-based autonomous network operation in an environment where demand from dense events and foreign users increases simultaneously.
