Through co construction and sharing, the quality of Shanghai 5g network has been continuously improved, and the network operation indicators have been significantly improved. According to the reporter, up to now, Shanghai Telecom and Shanghai Unicom have built and opened nearly 17000 5g outdoor base stations through the mode of sharing and co construction, basically realizing the full outdoor coverage of urban centers in the main urban areas and suburbs.
"In 2021, Shanghai Telecom completed the annual co construction and sharing goal issued by China Telecom Corporation Limited(601728) group ahead of schedule. The 5g co construction coverage increased significantly, and the download rate increased by more than 46%. In terms of network operation indicators, the 5g diversion ratio has increased to 30% and the 5g resident ratio has increased to more than 70% The relevant person in charge of network construction of Shanghai Telecom said. The higher the 5g dwell ratio, the more complete the 5g network coverage; The higher the 5g diversion ratio, the higher the 5g utilization rate, which has become the main bearing mode of information consumption.
According to the statistics of Shanghai Unicom, by sharing Telecom base stations, Shanghai Unicom can reduce the power consumption by about 360 million kwh every year.
A sound working mechanism has been formed between Shanghai Telecom and Shanghai Unicom. The heads of the two operators will regularly hold a leading group meeting on co construction and sharing to promote co construction and sharing. As early as the beginning of 2020, the two operators established a co construction and sharing team, and the personnel of both sides worked together to create "one team". The two operators have formulated six working principles such as "joint operation and undifferentiated service", established a decision-making mechanism for divergence upgrading and an integrated working mechanism of "planning, construction, maintenance and optimization", and made breakthroughs in the fields of joint planning, collaborative construction, integrated grid connection and 2b support.
China Telecom Corporation Limited(601728) and China United Network Communications Limited(600050) two large communication operators jointly build and share 5g full life cycle networks, which is the first in the world, providing "Chinese experience" for the global communication industry. Moreover, it is also a concrete practice of the new development concept of "innovation, coordination, green, openness and sharing", and accelerating the construction of digital information infrastructure Major measures to promote the development of digital economy. Nationwide, as of October 2021, China Telecom Corporation Limited(601728) and China United Network Communications Limited(600050) have jointly built and shared more than 600000 5g base stations, accounting for more than 40% of the number of 5g base stations built in the world. The world's first and largest 5g independent Networking (SA) Co built and shared network has been built, which has realized large-scale industrial applications, promoted 4G access network sharing at the same time, and saved more than 210 billion yuan in network construction investment, Every year, it saves 20 billion yuan of network operation cost, more than 10 billion kwh of electricity, reduces 6 million tons of carbon emissions, drives the upstream and downstream industrial chain, leads the global 5g development, and promotes the high-quality, healthy and green development of 5g industry.
In March 2021, the line and power administration of the Ministry of industry and information technology issued the technical requirements for base station RF of 5g mobile communication system in 2100mhz band (Trial). All along, the 2.1GHz frequency bands of China Telecom Corporation Limited(601728) and China United Network Communications Limited(600050) have been mainly used in 3G and 4G networks. China Telecom and China Unicom re plough the frequency band and deploy 5g, which helps to increase 5g coverage.
It is reported that Shanghai Telecom and Shanghai Unicom have promoted the re cultivation of the 2.1GHz frequency band originally used for 3G / 4G network, and used part of the bandwidth of this frequency band for 5g network, mainly to improve the quality of 5g coverage in indoor scenes such as buildings.
"In 2022, Shanghai Telecom will strengthen 5g indoor coverage, community coverage and 4G / 5G collaborative construction to create a higher quality 5g network." Introduction of relevant person in charge of Shanghai Telecom.
