5G-A，来了！

Core Viewpoint - The article discusses the emergence of 5G-Advanced (5G-A), also known as 5.5G, as an upgrade to traditional 5G technology, highlighting its significant improvements in speed, latency, and connectivity, as well as its broader application scenarios in various industries [1][2]. Group 1: Technical Enhancements - 5G-A offers a maximum data download speed increase from gigabits to 10 gigabits, and upload speeds from hundreds of megabits to 1 gigabit, enabling faster downloads of large files [1]. - The latency is reduced to millisecond levels, enhancing real-time communication applications such as online gaming and video conferencing, and making remote surgeries and industrial automation more reliable [1]. - 5G-A supports a larger number of devices simultaneously, ensuring stable connections in crowded environments like shopping malls and smart homes, thus facilitating the development of IoT and smart cities [1]. Group 2: New Application Scenarios - 5G-A introduces capabilities in three main directions: "integrated communication and sensing," which allows for real-time environmental awareness and data capture, enhancing applications in various fields [2]. - The "integrated communication and sensing" feature can improve vehicle traffic management and smart home automation by recognizing household activities and adjusting environments accordingly [2]. - 5G-A is positioned as a productivity engine, aligning with advancements in artificial intelligence, IoT, high-end manufacturing, and low-altitude economy, contributing to high-quality development of new productive forces [2]. Group 3: Accessibility and Deployment - To access 5G-A, users need compatible local base stations and mobile devices, with most mainstream models currently available supporting this network without additional charges [3]. - As of now, operators have deployed 5G-A testing networks across 31 provinces in China, with the capacity to support 50 million users [3]. - The Ministry of Industry and Information Technology emphasizes the importance of advancing 5G-A and 6G technologies, aiming to accelerate the establishment of new information infrastructure standards [3].
