Suggestions on how to write civil air defense communication signals well

In recent years, with the development of building technology and the application of new building materials, more and more high-rise residential buildings are equipped with elevators, and many people will encounter the problem of no signal when they take the elevator or make phone calls in underground parking spaces or storage rooms. Through interviews and investigations, it is found that there are no cell phone signals in elevators, underground garages and basements of many commercial residential quarters in our city.

According to relevant statistics, in recent years, complaints about poor signal in elevators, basements and other places remain high, especially in high-rise residential quarters. The number of complaints against these places is very large. Because of the unique structure of these places, it is difficult to cover wireless signals. Elevator signal coverage is a kind of deep coverage, which is also a headache for mobile operators and property management departments, and also affects the brand image of operators to some extent.

Therefore, it is suggested that the municipal government pay close attention to the people's livelihood in the city, set up special classes for relevant departments of the municipal government and operators such as China Mobile, China Unicom and China Telecom, and solve the obstruction problems such as base station construction, technical standards, fees and approval restrictions as soon as possible, so as to solve this problem that puzzles the masses and affects their convenient communication.

First, sort out the "stuck neck" problems in base station construction, technical standards, fees, approval and restrictions as soon as possible. For example, the elevator is a closed system, which is made of reinforced concrete from top to bottom, and the car is made of iron plate, which will filter the signal itself, so if there is a signal in the elevator, a signal amplifier should be installed. Sometimes, an elevator car needs to be equipped with three signal amplifiers, one at the top, one at the bottom and one in the middle. At present, all communication operators add their own products and cannot share compatibility with each other. For another example, with a signal amplifier, you need a base station to release signals. Some communication operators said that indoor distribution system can be incorporated into supporting construction in real estate development to ensure ideal signal coverage in indoor areas. For developed buildings and mature supporting communities, it is necessary for communication operators to build base stations in communities to achieve full coverage of 4G networks in communities. However, the current situation is that some residential properties do not allow base stations to enter, or set thresholds to collect electricity and parking fees. It is hoped that the relevant departments of the municipal government will sort out the relevant problems in time and solve them one by one according to the requirements of the "year of work implementation".

The second is to carry out statistical investigation on the coverage of mobile communication signals in elevators and underground civil air defense facilities as soon as possible. Conduct a thorough investigation in the whole city, organize and coordinate all telecom operators to find out the coverage of the city's 5G network and the depth coverage of key areas such as elevators, underground civil air defense facilities and underground facilities of commercial residential quarters as soon as possible, implement inventory management for areas with weak communication coverage, and formulate the allocation table of communication infrastructure construction promotion plan documents. Grasp the first-hand information and lay a solid foundation for the full coverage of mobile communication signals.

The third is to increase government support and speed up the construction of communication infrastructure. Study and formulate the compensation system and standard for the demolition of communication infrastructure, and determine the use price of communication pipe gallery through fair consultation. Accelerate the environmental assessment procedures for the construction of base stations and iron towers, open up green channels and implement centralized examination and approval. Increase financial support and arrange certain financial funds to support the information construction of elevators and underground civil air defense facilities covering mobile communication signals.

The fourth is to strictly implement the construction norms, not to approve the pre-sale and not to accept the completion. Strictly implement the norms for the construction of communication facilities, realize resource sharing and fair competition, and promote the orderly development of communication infrastructure. Conscientiously implement the national fiber-to-the-home standard, and the new residential area should have access conditions for multiple telecom operators; Implementation of the city's building mobile communication infrastructure construction norms, mobile communication infrastructure construction should be synchronized with the building planning, synchronous design, synchronous construction, synchronous acceptance.

Jin Haiyang Representative:

Your Bureau's "Proposal on Compulsory Coverage of Mobile Communication Signals by Elevators and Underground Civil Air Defense Facilities in the City" has been received, and we hereby reply as follows:

In recent years, with the popularization and application of mobile communication technology, especially the rapid development of 5G technology, the contradiction between people's demand for mobile communication services and poor wireless signal coverage is becoming more and more obvious, especially for key public transportation places (subways, railways, highways, airports, stations, docks, etc. ), large venues (gymnasiums, exhibition centers, libraries, etc. ), commercial buildings, elevators and large underground public parking lots used by many owners.

In 20 16, our province issued the Code for the Construction of Building Mobile Communication Infrastructure, and formulated five technical specifications concerning communication room, communication power supply, communication pipeline, roof facilities and acceptance, giving clear guidance to new civil buildings, industrial buildings and existing reconstruction and expansion projects. It is clear in the specification: "The infrastructure of indoor distribution system should be set in key public transportation places (subway, railway, highway, airport, station, wharf, etc.). ), large venues (gymnasiums, exhibition centers, libraries, etc. ), commercial and residential buildings and commercial buildings used by many owners, buildings of party and government organs with a building area of more than 3,000 square meters and other public buildings with a building area of more than 20,000 square meters. " At the same time, the housing and urban-rural construction department requires all construction units to "synchronize planning, design, construction and acceptance" according to the construction situation of mobile communication infrastructure, meet the requirements of equal access for many mobile communication operators, and review the construction plan.

At present, there are no relevant regulations in the industry, requiring elevators and underground civil air defense facilities to cover mobile communication signals. In the next step, our bureau will actively cooperate with the departments of development and reform, science and technology, industrial informatization, big data, etc., fully investigate the planning and design of mobile communication infrastructure in new residential areas and the reconstruction and expansion of mobile communication infrastructure in built residential areas, select some pilots, and introduce relevant measures to promote the full coverage of mobile communication signals in a solid and effective manner.

Thank you for your concern about government work, and please continue to pay attention to and supervise our work.

Municipal Bureau of Industry and Information Technology:

Dear representative of Golden Ocean,

Your Bureau's "Proposal on Compulsory Coverage of Mobile Communication Signals by Elevators and Underground Civil Air Defense Facilities in the City" has been received, and we hereby reply as follows:

In recent years, the municipal party committee and government have attached great importance to the construction of basic communication facilities, actively guided relevant departments to cooperate with the three major operators, and constantly optimized the construction environment of basic communication facilities. It has successively issued the Implementation Opinions of Dezhou Municipal People's Government Office on Further Standardizing the Construction and Management of Mobile Communication Infrastructure, the Notice of Dezhou Planning Bureau of Dezhou Housing and Urban-Rural Development Bureau on Implementing the Construction Specification of Mobile Communication Infrastructure (Dejiantong [20 16] 107) and the Notice of Dezhou Municipal People's Government on Printing and Distributing the Construction Plan of Emergency Rescue and Disposal Platform for Elevator Trapped Persons in Dezhou. A series of documents, such as the Notice of Dezhou Municipal People's Government Office on Printing and Distributing the Implementation Plan for Promoting the Co-construction and Sharing of High-level Resources and Accelerating the Construction of Mobile Communication Facilities, and the Implementation Opinions of Dezhou Municipal People's Government Office on Accelerating the Development of 5G Industry, provide fundamental guidance for standardizing the construction of mobile communication facilities and optimizing the construction environment of basic communication facilities. Ma Junyun, vice mayor, and others have held joint meetings of mobile communication facilities for many times, with multi-department linkage, strengthened cooperation, studied and solved difficulties and problems in project promotion, and improved supporting service systems such as planning, supporting construction, examination and approval process, public resources opening and network resources coverage.

After a thorough investigation, there are about 720 high-rise residential quarters, about 23,000 elevators and 750 underground garage storage rooms in Dezhou, and all kinds of civil air defense facilities are complete, including 33 1 high-rise residential quarters, 5,800 elevators and 80 underground civil air defense facilities. Unicom signal has covered 12 1 high-rise residential quarters, about 1600 elevators and 60 underground civil air defense facilities. The signal of telecom company has covered 3 10 high-rise residential quarters, about 1800 elevators and 140 underground civil air defense facilities.

Due to the intensification of urban construction in recent years, there are still many problems in the construction of mobile communication infrastructure. Elevator and underground civil air defense facilities have low signal coverage. The fundamental reason is that the elevator construction in residential buildings is large, the elevator shaft is high, the coverage construction is difficult and the signal attenuation is serious. Underground garages and other civil air defense facilities have a large area and a large investment in deep coverage. Operators can only implement deep coverage of signals in stages. In the construction planning of some high-rise residential quarters, the mobile communication infrastructure is not included in the synchronous construction planning, and the signal coverage problem is often considered after completion, which makes it difficult to select the base station and improve the construction difficulty of communication lines. Some built communities also have the problems of super-high field rent and high admission fee. At the same time, some residents in the community misunderstand the radiation of the base station, which makes it difficult for the base station to enter the community from time to time.

In order to further standardize the construction of mobile communication facilities, we will mainly do the following work.

(1) Improve the system of joint meetings. Coordinate the three operators to conduct a thorough investigation on the coverage of mobile communication signals in high-rise residential areas, elevators and underground civil air defense facilities in Dezhou, sort out and summarize the "stuck neck" problems existing in the process of base station construction and approval, and establish a list of problems. Convene joint meetings of communication infrastructure planning and construction with three operators, Housing and Construction Bureau, Bureau of Industry and Information Technology and other departments as members on a regular basis to coordinate and solve existing problems.

(2) Strengthen resource sharing. In view of the existing high-rise residential buildings, elevators and civil air defense facilities, the three operators sorted out the detailed distribution of indoor distribution systems of all parties. For scenes with existing indoor systems, coordinate operators to share them as free as possible, reduce redundant construction and save investment. Three operators are not at the scene to coordinate the overall construction. At the same time, coordinate the three operators to increase their efforts to win project and financial support, and strive for the city's policy inclination to the maximum extent.

(3) Strictly implement the construction standards. Coordinate the relevant departments directly under the municipal government to strictly implement the standards such as Code for Design of Communication Facilities in Residential Areas and Residential Buildings by the Ministry of Housing and Urban-Rural Development, Code for Design of Fiber-to-the-Home Communication Facilities in Residential Areas and Residential Buildings, Code for Construction of Building Mobile Communication Infrastructure by the Housing and Construction Department of Shandong Province, Regulations on Construction and Protection of Communication Infrastructure in Shandong Province, and Implementation Opinions of the General Office of Shandong Provincial People's Government on Accelerating the Development of 5G Industry. Specifications and documents, speed up the implementation of the relevant policies for supporting the construction of communication infrastructure in new residential areas, strengthen the mobile signal coverage and communication base station construction in special scenes such as elevators and underground garages in built residential areas, and incorporate the supporting construction of communication facilities and effective signal coverage in high-rise residential areas into planning, construction and acceptance.
