**Introduction to 5G**
5G stands for the fifth generation of mobile communication technology. Unlike previous generations, which were based on single wireless technologies, 5G is a combination of various existing and emerging technologies. It aims to provide faster data transfer, lower latency, and better connectivity than ever before.
The current 4G networks have limitations when it comes to handling high-definition video, immersive audio, augmented reality (AR), and virtual reality (VR). To address these challenges, 5G introduces advanced technologies that improve spectrum efficiency, expand available frequency bands, and increase the density of network cells. This allows for a more robust and scalable network, supporting high-speed data transmission, massive device connectivity, low latency, and a superior user experience.
**13 Cities Test 5G – Does Your Family Have 5G?**
China’s three major telecom operators—China Mobile, China Unicom, and China Telecom—are conducting 5G trials in 13 cities across the country, including Beijing, Shanghai, Guangzhou, Shenzhen, Wuhan, Chengdu, Tianjin, Nanjing, and others. These pilot projects are part of a broader strategy to accelerate the rollout of 5G technology nationwide.
China Mobile has started testing in five cities: Hangzhou, Shanghai, Guangzhou, Suzhou, and Wuhan. In addition, it will demonstrate 5G services in 12 other cities, covering applications like 4K HD streaming, AR, VR, drones, and more. China Unicom’s pilot cities include Beijing, Tianjin, Shanghai, Shenzhen, Hangzhou, Nanjing, and Xiong’an, while China Telecom’s focus is on Chengdu, Xiong’an, Shenzhen, Shanghai, Suzhou, and Lanzhou. Notably, Shanghai is the only city where all three operators are conducting trials.
China Telecom opened its first 5G base station in Shenzhen on October 27. Later, on November 8, it launched a 5G base station in Xiong’an, with field tests showing a 20x improvement in speed compared to 4G. Earlier in August, China Telecom announced the launch of its 5G innovation network in Xiong’an, aiming for commercial trials by 2019 and full commercialization by 2020.
The rapid deployment of 5G base stations in six major cities indicates strong preparation and coordination between China Telecom and its partners. For example, 5G base stations were opened in Suzhou on November 10, Shanghai on November 11, Chengdu on December 1, and Lanzhou on December 2.
Looking ahead, China Telecom plans to deepen collaboration with equipment manufacturers and chipmakers, as well as explore 5G applications in vertical industries such as AR, VR, smart cities, autonomous vehicles, and industrial IoT. The company has also been actively involved in global 5G standardization efforts since 2016, submitting over 250 technical proposals and 100 patents.
**How Fast Is the Measured 5G?**
Qualcomm conducted extensive simulations to evaluate 5G performance in real-world conditions. The experiments were carried out in two cities—Frankfurt and San Francisco—using different frequency bands and network configurations.
In Frankfurt, Qualcomm simulated an NSA 5G network operating on a 3.5 GHz band with a 100 MHz bandwidth. The results showed a dramatic increase in download speeds, from an average of 56 Mbps on 4G to over 490 Mbps on 5G, representing a nearly 900% improvement. The response time was reduced by almost seven times, and users experienced much smoother browsing and faster downloads.
In San Francisco, the simulation used a 28 GHz millimeter-wave band with an 800 MHz bandwidth. The results were even more impressive, with 5G download speeds reaching up to 1.4 Gbps—over 2000% faster than 4G. Users could stream ultra-high-definition content, including 8K videos at 120 FPS with 10-bit color, showcasing the transformative potential of 5G.
**How 5G Changes the Future**
5G isn’t just about faster downloads—it represents a fundamental shift in how we connect and interact with the digital world. Unlike earlier generations, which focused mainly on speed, 5G enables ultra-fast data transfer, ultra-low latency, and massive IoT connectivity.
According to Qualcomm, 5G is expected to generate $12.3 trillion in global economic output by 2035. It could contribute significantly to GDP growth, potentially matching the size of India’s economy over the next 15 years.
At the PyeongChang Winter Olympics, 5G made its debut with the world’s first large-scale 5G network in the 28 GHz band. This marked a milestone in the development of 5G technology and demonstrated its potential for real-time, high-quality media streaming and immersive experiences.
