During the recent “5·17†telecommunications day, the three major operators have joined forces to showcase their rich 5G applications in various demonstration and pilot cities and share their respective trial network planning. It is reported that Datang Mobile participated in the construction of China Mobile's 5G trial network in Wuhan, and also launched 5G drones, smart factories and other wonderful displays. Regarding the next 5G test construction plan of Datang Mobile and China Mobile and the challenges in construction, the all-media reporter of the Communication World interviewed Chen Bo, Marketing Director of Datang Mobile 5G Product Line.

Join hands with Hubei Mobile to showcase exciting 5G applications
China Mobile Hubei Company (hereinafter referred to as Hubei Mobile) plans to build more than 100 5G base stations in the core areas of Wuhan Optics Valley and the Yangtze River main axis this year to achieve 5G continuous coverage and carry out relevant technical verification and testing with the partners. By September 2019, 5G commercial trials will be launched; by 2020, 5G networking, construction, optimization, operation and other content research and verification will be completed, forming a complete commercial technology system with commercial operating conditions.
On 517 World Telecommunication Day, Datang Mobile and Hubei Mobile jointly organized the “5G Dare for the First Smart Beauty Green Road Technology Carnival†event. This exhibition is very important, and it can be said that Hubei Mobile 5G development has made an overall appearance. Chen Bo introduced that in this event, the contents of the 5G main exhibition area set by the two parties, including the image display area, the experimental network display area, the communication knowledge popularization area, the industrial capability display area, the business interactive experience area and the artificial intelligence experience area, were divided into six parts. .
In the exhibition area, ultra-low latency UAV based on 5G technology can remotely control and quickly respond to each command, making emerging applications such as driverless and smart cruise possible; the robot arm with 5G technology will be The "smart brain" is characterized by information-aware acquisition and intelligent judgment and decision-making; Beidou satellite navigation system and 5G mobile communication technology are deeply integrated, which can shorten the first positioning time, achieve centimeter-level accuracy requirements, and comprehensively enhance the service of Beidou system. performance.
After "5·17", the 3GPP 5G SA (Independent Networking) standard will also be determined in June. In this regard, Chen Bo said that the determination of the SA standard will gradually shift the test network from the NSA verification phase to the NSA and SA verification phase. “Datang Mobile is closely participating in and tracking the development of SA standards, and has completed the product development, production and operator laboratory test, to ensure that the SA construction and testing of the test network in each place is carried out according to plan.†Chen Bo said .
Datang Mobile and its operators have promoted 5G trial commercials in a multi-pronged manner
In the face of the value brought by 5G applications, from the beginning of 2017 to the beginning of 2018, various operators and places have started the construction of 5G test network. However, compared with the previous test network such as 4G, the 5G test network has some new challenges in addition to the conventional construction problems. Chen Bo gave a detailed introduction to this.
First, due to the initial stage of construction, the 5G standard has not been determined, and the non-standard products pre-researched by various manufacturers are facing more or less replacement and iterations, which puts new requirements for deployment, construction and arrival, and needs to be fully evaluated. The guiding significance of the pilot small-scale non-standard products to the follow-up large-scale experimental network construction planning, accurate theoretical calculation, simulation and field test to ensure the accuracy of the overall planning.
Second, 5G equipment has high requirements for transmission and supporting resources, and some requirements are even revolutionary. How to coordinate the resources of operators, towers, municipalities, etc., and complete the transformation of the equipment room, the sky surface and the transmission supporting facilities within a short period of time to ensure that the air-conditioning and power supply of each station meet the expectations, and the antenna feeder meets the planning and coverage needs, etc. New challenges were raised for the on-site executive team and the various stakeholders.
Third, due to the coverage and planning indicators of 5G NR, the parties are still exploring and formulating the stage. This also brings some reasons to the operator's network planning, site selection, test expectations, etc. Certainty.
However, Chen Bo also pointed out that it is precisely because of the difficulties and uncertainties that the construction of the test network and the full test are particularly important. It requires the employees and all relevant parties to continuously explore and explore the actual stage in the trial network. Departure, find problems, solve problems, and accumulate experience for 5G's formal commercialization.
Datang Mobile is actively participating in the pilot construction of 5G trial network for operators in many places. It is believed that with the joint efforts of operators, it has the ability to confidently meet the challenges, help operators build and technical verification of 5G trial network, and promote 5G industry. Commercially mature. Chen Bo finally said.
