"If you want the country to be rich and strong, you must not ignore the ocean." Wealth comes from the sea, and danger also comes from the sea", this quote of Zheng He recorded in "Overseas Chinese" is still applicable at present.
Since the commercialization of 5G, there have been many innovative changes in consumer applications and industrial applications of 5G. Just now, we found a blueprint for the application of 5G in the ocean in a Fujian film.
"5G Eight Fujian Tides Surging Haixi" focuses on one of the most oceanic places in China's territory: Fujian. The Bamin region is located on the edge of farming civilization and the center of marine civilization, where Fujian Mobile is working with Huawei to catalyze a variety of offshore 5G services through the establishment of offshore 5G sample points, setting 5G standards for the global smart marine industry.
The 5G story of 2022, let's start with the ocean.
5G is in Fujian, Fujian is in the sea
Discussing marine science and technology in China is inseparable from the most typical marine ethnic group "Min". The "Classic of Mountains and Seas" records that "Fujian is in the sea" is the most profound summary of the geographical location and cultural traditions of the ancients, and also explains why 5G can travel here.
From a geographical point of view, Fujian is "coastal" and "mountainous", with more than 3,000 kilometers of coastline and abundant marine resources, becoming a natural capital for 5G to embrace the sea. According to the preliminary coverage plan of Fujian Mobile, the mainland coastline of the mainland is 18,000 kilometers, and there is still a lot of room for the development of 5G sea areas.
Economically, Fujian has a long history of developing the marine economy, and today, the Fujian region is also the gateway to China's "Maritime Silk Road". The rapid growth of fishing and steak farming, offshore wind power, offshore government affairs, and maritime tourism has spawned a variety of data communication needs, and 5G coverage is strong.
From a scientific and technological point of view, the Bamin region also has a deep marine scientific and technological heritage, Zheng He's Fu boat, was the world's largest wooden sailing ship at that time, named because it was produced in Fujian, the level far exceeded the fleet of Columbus, Magellan and so on decades later. Such Fujian naturally has the awareness of taking the lead in embracing advanced technologies such as 5G.
It is not difficult to understand why the 5G-supported smart ocean was born in the Bamin region.
Ocean Travel, 5G Song
Traditional maritime communication, or rely on satellite transmission, which requires a large-scale satellite swarm, limited capacity, high tariffs, it is difficult to support the needs of ordinary users and small and medium-sized fishermen, marine institutions; the second is to rely on submarine cables, China has successively launched a number of submarine cable laying plans, the construction period is long, can not meet the needs of rapid growth of marine business; the third is to rely on the coastal areas have been covered by the 4G network, in the offshore experience is not good.
In this situation, the construction of a network in 5G sea areas has naturally become imminent and worthwhile.
Taking the ultra-long-distance three-dimensional coverage scheme for 5G sea areas created by Fujian Mobile and Huawei, what chapters are composed of supporting the development of offshore and coastal marine business?
The first part: the "Water Dragon Yin" of maritime supervision.
With the development of China's marine economy and the growing "circle of friends" of the Maritime Silk Road, sea-related activities have become more and more numerous, and many more refined supervision. In the Fujian region, a situation of "five dragons controlling water" has been formed by maritime regulatory departments.
The daily operation of these departments is inseparable from the communication support of large bandwidth, wide coverage and high rate.
Fujian Mobile and Huawei, in the blue space of the ocean, have planned a number of applications such as panoramic video surveillance of uninhabited islands, visual supervision of maritime, supervision of anchorage production and operation, import and export inspection of fishing vessels, and marine global network coverage.
On the one hand, improve the transparency of management. 5G networks transmit video back to the cloud in real time, allowing the law enforcement process to be traced back.
At the same time, improve management efficiency. Terminals such as 5G remote control unmanned aerial vehicles and shipboard 5G cameras can reduce the difficulty of supervision by superimposing AI recognition capabilities. For example, the "5G + cloud boarding ship" planned for the Maritime Safety Bureau replaces the traditional "satellite communication + helicopter airborne law enforcement personnel" method, and reduces the cost of law enforcement while avoiding personnel contact through the voice and video contact methods supported by the 5G network, which meets the requirements of epidemic prevention and control.
In addition, expand the regulatory area. In the sea area 50 kilometers away, through Huawei's ultra-long-distance sea area coverage solution, voice calls can still be realized and the blue space can be better managed.
The second part: the "symphony" of the marine economy.
According to the "China Marine Development Report (2018)" released by the State Oceanic Administration, China's marine economy has maintained rapid growth, and in 2017, China's total marine economy reached 7.76 trillion yuan, accounting for 9.4% of GDP.
However, due to the constraints of marine resources and environment, the rising cost of production factors such as labor, and the difficulty of marine development and utilization, there are still some shortcomings in the development of the marine economy. The arrival of 5G has played a "symphony" of innovation in many industrial fields.
For example, the rapidly developing offshore wind power industry has long been plagued by the problems of difficult operation and maintenance and expensive manpower. Fujian Mobile and Huawei jointly built 5G AR remote O&M, offshore wind power automatic inspection and fault diagnosis to solve O&M problems.
Through the 5G network, remote users can directly carry out spatial annotation in the real-time communication screen of AR glasses, integrate the annotation information with the physical environment and physical objects, guide on-site personnel to carry out maintenance, and reduce the labor and time cost of experts arriving at the scene. The use of drones also makes daily inspection and troubleshooting more secure and convenient.
The third part: the "aria" of the people's livelihood in the sea.
The development of the blue economy is inseparable from the participation of fishermen and workers. Due to the development of fisheries, Fujian has also formed a floating cage aquaculture industry, which has attracted a large number of people to gather and live on fish steaks, forming a dense and large-scale maritime community. In the Ningde region of Fujian alone, from April to October every year, hundreds of thousands of people live on fishing rows, and the needs of these residents have also spawned maritime clinics, hotels and other formats, due to the need for basic communication guarantees.
Fujian Mobile and Huawei's 5GtoC application enhances the broadband experience of resident fishermen, tourists, drilling staff, etc. through 5G network construction. A better network has also made applications such as live broadcasting popular, becoming an "artifact" that drives fishermen's income. Lianjiang fishing steaks are brought through live broadcasts, opening up sales channels for unsalable abalone.
Fujian Mobile and Huawei's pioneering explorations have played the song of 5G over the ocean, composing the offensive music of the digital age.
A maritime power, "leading the stars across the ocean"
More than 600 years ago, Zheng He led a fleet to the east coast of Africa through the "star-drawing technique", and wrote a strong stroke of Chinese navigation. Today, 5G also needs to have the ability to "lead the stars over the ocean":
First, lead the standard.
The scale of the leading star plate can measure the height of the stars. As a leader in 5G, China's communications industry is also facing the heavy responsibility entrusted by the times: determining the standards for building networks in 5G sea areas.
In the 5G sea area wide and deep three-dimensional coverage scheme created by Fujian Mobile and Huawei, according to the characteristics and business distribution of 5G ultra-long-distance coverage, the sea area is divided into coastal (about 10km offshore), offshore (about 30km offshore) and high sea (about 50km), and puts forward the standard of "excellent coastal experience, stable offshore signal, and high sea calling", becoming the forerunner of network construction in global 5G sea areas.
Second, lead the technology.
The curvature of the earth, the height of the base station and the position of the terminal will all interfere with the network coverage distance. To meet the network construction standards in different sea areas, it is necessary to innovate and apply a variety of technologies. For example, in the coastal coastal areas, through TDD+FDD dual-frequency networking, SUL uplink enhancement technology, high frequency and low frequency synergistic complementarity, time domain and frequency domain aggregation, to achieve coastal area experience coverage, sea and land with the same network speed.
Third, lead the way.
The foundation of the 5G sea area network is to become the base for the development of marine space and help the digitization and intelligence of related industries. Fujian Mobile Provincial Company, Ningde City Company and Huawei jointly built a 5G smart ocean model point in Ningde to incubate marine business in the 5G-covered sea area. With the introduction of intelligent technologies such as AI, AR/VR, machine vision, and unmanned driving, the value of the network can be transformed into application value, which can truly help the marine industry to reduce costs and increase efficiency and grow at a high speed. From this point of view, Huawei, which has 5G + cloud + AI full-stack technology capabilities, complete tool chains, and integrated solutions, is equivalent to having a "nautical chart", making 5G landing and industrial integration faster and more stable.
The history of the ocean is also an evolutionary history of science and technology. From wooden paddle sails to steam ships, from fukugawat cannons to aircraft carriers. As another stage for human survival and development, the ocean is naturally indispensable to the figure of 5G.
"5G spring breeze comes, the marine economy flies", Fujian Mobile's exploration and attempt, is making every drop of seawater shine with wisdom, holding up the industrial ship to ride the wind and waves, sailing to the sea of digital waves, a different 5G era.
