Keysight showcase solutions that accelerate the wireless evolution at Mobile World Congress 2023

Accelerate 5G

• Boost IoT with 5G RedCap: RedCap (Reduced Capability) 5G is a new optimised design for mid-tier use cases. Keysight's IoT security solution combined with 5G network emulator optimised for RedCap testing will demonstrate advanced security testing on a realistic RedCap network.
• Emulate Non-Terrestrial 5G: As tens of thousands of low earth orbit (LEO) satellites, or "mega" constellations launch, companies require test solutions to characterise performance of non-terrestrial networks (NTN). Keysight's NTN testbed demonstration will apply timing and Doppler pre-compensation, use extended hybrid automatic repeat request (HARQ), and measure device-under-test block error ratio (BLER) and throughput.
• Test Metaverse Devices: Using Eggplant Intelligent Automation, Keysight will test a 5G-connected HoloLens augmented reality (AR) / virtual reality (VR) device user interface (UI) and the user experience (UX). The device connects to a 5G Network Emulation Platform to validate application scenarios.
• Evolve Vehicle to Everything (V2X) Communications: Keysight will demonstrate how to run radio frequency (RF) and protocol tests to on-board unit (OBU) and road-side unit (RSU) certification for dedicated short-range communications (DSRC). The 5G Network Emulation Platform and C-V2X toolchain will create a complex scenario with congestion testing.

Advance Open RAN

• Develop 5G Green Networks: Energy efficiency is a top network operator priority as networks grow in capacity and reach. Optimising energy consumption without impacting the end-user experience requires cross-domain energy and performance KPIs, coupled with energy-saving mechanisms and intelligent control from RAN to core. Keysight and Analog Devices partner to showcase automated radio unit (RU) energy efficiency benchmarks and highlight gains using advanced energy saving mechanisms. Keysight will also demonstrate its O-RAN energy saving solution, which can reduce power consumption in a multi-vendor, cloudified ORAN system using intelligent control, telemetry, and power management features.
• Analyse O-RAN Massive MIMO: This demo showcases how to test downlink and uplink instantly, single-user and multi-user massive MIMO RF beam shape / weight measurements, or specific RF parametric measurements on multiple TR radios. Keysight will also demonstrate how to analyse the 5G New Radio (NR) air interface, including fronthaul signals and traffic in detail using WaveJudge.

Deploy private networks

• Deploy & Optimise Private 5G: Keysight will demonstrate how to validate and diagnose 5G private networks, using a combination of Keysight solutions such as the new Nemo industry probe for active monitoring of Industry 4.0, FieldFox analyser with its wide frequency and bandwidth coverage for field testing and site acceptance, and WaveJudge Wireless Analyser for full-stack audit of the air interface.

Shape future technologies

• Enabling early research in future technologies, including 6G: Network modeling spotlights how real-world data and behavior models can be achieved using digital twins to evaluate power consumption and analyse energy efficiency. Keysight will demonstrate the full potential of our network modeling solutions. Modeling future air interfaces demonstrates why the integration of machine learning (ML) technologies into the new air interface is essential for future wireless evolution. PathWave System Design Software simulates a model of a 5G physical layer and a 3GPP wireless channel, then estimates the channel. Using electronic design automation (EDA) software and real hardware connections, the demonstration will quantify the performance difference between traditional and new machine learning techniques.

• Sub-THz research: Frequency bands above 100GHz open new possibilities to deploy extreme data-rate communications and sensing. This demo showcases unprecedented bandwidth, data rate, and error vector magnitude (EVM) capability at 142GHz. Developed specifically for 6G, this proprietary technology and measurement science allows researchers to know exactly what is happening in their innovative designs.
