5G-A Arrives in Kunming Subway, Delivering BlazingFast Speeds
Kunming, Yunnan Province, China – YunnanMobile has successfully deployed the province’s first 5G-A (5G-Advanced) base stations within the Kunming subway system, marking a significantleap in mobile connectivity for the region. The new base stations, located at Panjiawan Station on Line 3 and Juhuacun Station on Line 4,have achieved peak download speeds of 3.94 Gbps, a remarkable feat for a subway environment.
This initiative, announced by the Kunming Metro Authority, leverages cutting-edge technologies like Ultra-Reliable Low Latency Communication (URLLC), Real-Time Broadcast and Communication (RTBC), and Hybrid Communication and Sensing (HCS) to enhance passenger experience. Passengers can now enjoy seamless high-definition video streaming, crystal-clear video calls, and other bandwidth-intensive serviceseven while underground.
These base stations are equipped with advanced features that cater to the unique demands of a subway environment, explained a spokesperson from Yunnan Mobile Kunming Branch. They not only provide exceptional connectivity for passengers but also support the implementation of various intelligent applications for subway operations.
To achieve this breakthrough, Yunnan Mobilehas implemented a comprehensive network upgrade using LampSite X four-frequency stations (1.8G+2.3G+2.6G+4.9G). This innovative solution, a first of its kind in the industry, combines four frequencies into one, resulting in a significant reduction in weight, size, and powerconsumption compared to traditional solutions.
Furthermore, the Juhuacun Station on Line 4 features the industry-leading QCell 4-band active digital distributed system. This highly integrated multi-frequency, multi-mode device supports 1.8G, 2.3G, 2.6G, and4.9G frequency bands simultaneously, enabling the simultaneous operation of 4G and 5G networks.
5G-A: The Next Evolution of Mobile Connectivity
5G-A, also known as 5.5G, represents the next evolution of 5G technology. It boasts enhancedcapabilities, including:
- Ultra-high speed: Theoretical peak speeds can reach 10 Gbps.
- Massive connectivity: Supports a greater number of devices simultaneously.
- Ultra-low latency: Delivers near-instantaneous response times.
- Integrated communication and sensing: Enables seamless integration ofcommunication and sensing functionalities.
- AI-powered intelligence: Leverages artificial intelligence for optimized network performance.
This technology is poised to revolutionize various industries, including autonomous driving, smart manufacturing, and immersive entertainment.
Expanding 5G-A Footprint
In March 2023, ChinaMobile announced its commitment to deploying 5G-A commercially in 100 cities across the country, with plans to expand to 300 cities by the end of the year. The successful implementation of 5G-A in Kunming subway marks a significant step towards realizing this ambitious goal.
Thisgroundbreaking initiative showcases the commitment of Yunnan Mobile and Kunming Metro to providing passengers with an unparalleled mobile experience. The deployment of 5G-A in the subway system promises to enhance passenger comfort, convenience, and safety while paving the way for future innovations in smart transportation.
