TapTechNews August 7th news, the Shanghai government released the 5G Network Offshore Coverage and Converged Application '5G Lan Hai' Action Plan (2023-2024) (hereinafter referred to as the Action Plan by TapTechNews) at the 5G Lan Hai Converged Application Development Conference, and it was officially written into the 2024 Annual Work Key Points for the Construction of a Modern Marine City in Shanghai.
Data shows that in 2023, the marine gross product value of Shanghai reached 990.16 billion yuan, accounting for 21% of the city's total GDP and 10% of the national marine gross product value, forming three pillar industries: marine transportation, marine tourism, and marine shipbuilding industry.
The Action Plan shows that by the end of 2023, Shanghai's various basic telecom enterprises have cumulatively built 1800 5G base stations and 1491 4G base stations related to the sea, realizing extensive coverage from the coastal to the offshore and distant sea areas, laying a solid digital foundation for Shanghai to build an internationally leading modern marine city and a leading area for the construction of a marine power with Chinese characteristics.
It is reported that Shanghai Mobile, in cooperation with Huawei, has completed the commercial verification of the world's first 2.6G 64T dual-combined ultra-long-range high-quality network, promoting the extension of the 5G network to the ocean, which can effectively meet the data service requirements such as online handling of in-and-out port business, marine accident rescue, remote command, and web browsing, high-definition video calls, and high-definition live broadcasts for international cargo crew members of Yangshan Port.
In addition, the marine 5G terminal equipment independently developed by the Shanghai Industrial Innovation Center of the China Academy of Information and Communications Technology has a built-in antenna array specifically for the characteristics of marine wireless signal propagation, which perfectly combines with the existing 5G base stations. The pilot test shows that the farthest distance of the 5G network from the shore reaches 83.79 miles, and the downlink rate of the network speed at the mouth of the Yangtze River in Shanghai reaches 124.27 Mbps and the uplink rate reaches 4.95 Mbps.
In terms of the 5G smart marine network architecture, currently, Chinese operators divide the marine network into four types of areas such as coastal (0-20 km from the shore), nearshore (20-40 km), distant sea (40-100 km), and ultra-distant sea (more than 100 km) from the perspectives of the offshore distance, user types, and business requirements. With the goal of excellent experience in coastal areas, stable signal in nearshore areas, and reachable in distant sea areas, and in combination with the network demand of coastal ports and low-altitude drones, it is committed to building an integrated network communication ability of land, sea, air, and sky and a three-dimensional network with coordinated heaven and earth.
On the part of the operators, the 4G+5G base stations jointly built by Shanghai Telecom and China Unicom have reached more than 900, completing the full coverage of 4G/5G within 10 kilometers from the shore of the Yangtze River estuary, and the coverage rate within 30 kilometers in the nearshore area has reached 70%, and the coverage rate within 50 kilometers in the distant sea area has also reached 50%.
China Mobile and China Radio and Television jointly build and share 700 MHz 5G sites and fully share 2.6 GHz 5G sites. Currently, it has achieved good coverage in the North Channel deep-water fairway, South Channel fairway, South Branch fairway, Yangtze River fairway, and the distant sea area of 45 kilometers. A total of 4 new island stations have been built, and the coverage distance has been increased to more than 75 kilometers at most.
