In the indoor scene where the mobile traffic is most concentrated, accurate monitoring of the indoor distribution system has been a difficult problem. In the recent TD Industry Alliance sponsored by Xi'an O-Telecom Technology Co., Ltd. co-organized "Mobile Internet of Things distribution management system seminar", TD Alliance Secretary-General Yang Hua said that despite the current 4G has matured, but the domestic indoor distribution system Of the active part has achieved effective monitoring, and the passive part so far there is no reliable and effective monitoring and online real-time management measures, the status quo is not optimistic.
For example, a large number of branches and end devices in passive distribution systems (such as antennas, feeders, connectors, passive components, etc.) are in an unmonitored state. There are many hidden dangers. Due to lack of real-time monitoring and supervision of end devices, network quality problems Can be repaired by user complaints, operation and maintenance is very passive, resulting in a waste of manpower and engineering maintenance costs. All these require telecom operators to completely change the supervision of passive antenna system.
How to make room points passive system to achieve intelligent management
In response to these questions, the Forum proposed a solution MIOTSS (Mobile Communication IoT Distribution Management System) that applies IoT technology to indoor passive distribution systems to change the regulatory approach. Yang Hua said: "indoor distribution system for many years in a" labor-intensive "state, its technical level to enhance and intelligent management issues such as the industry's attention is not high.Australia Telecom, including industry chain enterprises in the application of Internet of Things Technology to improve the intelligent management of passive distribution system and maintain a reasonable cost, made a useful attempt. "
When explaining the features of the MIOTSS program to the media, Wang Jianguo, chairman of Xi'an Aotong Telecommunications Technology Co., Ltd., mentioned that the system has gone through 3 years of study from abroad, site investigation and college demonstration. The project now consists of basic information, information statistics, Fault alarm, system settings, document output 5 modules, through the sensor acquisition of passive components, antenna feeder technical indicators and status of intelligent cloud computing to achieve quality management, in order to achieve real-time monitoring of the system network and passive components Monitoring, automatic detection and monitoring of alarm positioning, optimization of network services, so that passive devices to achieve the object connected, man-machine dialogue.
Technical characteristics and goals
From a technical point of view, MIOTSS by IOT sensor collection indoor distribution system performance indicators and status, and then through the IoT base station intelligent processing, through the background of big data processing to provide customers with the operation and maintenance of comprehensive services, a substantial reduction Investment in supervision, supervision, inspection and acceptance, asset management and after-sales service on behalf of maintenance management in the construction of subsystems also solved the huge investment in manpower, material and financial resources.
From a goal point of view, MIOTSS will provide a full range of IoT intelligent management of cloud computing and big data systems for a sub-project that will bring operators 70% of traffic revenue. It will also extend its industry IoT management services to other industries field.
It is reported that over the years the industry chain in the indoor distribution of passive antenna system monitoring have invested a lot of research and development efforts, is still only partial technical feasibility studies and not yet formed a system of patented technology. However, the management of passive antenna-fed room system urgently needs to solve the real-time management of intelligent monitoring and insertion / loss links on software and hardware, and more needs to be combined with technologies such as cloud computing big data to realize platform management and control. The MIOTSS system, which has these capabilities, has been piloted in different scenarios of China Mobile, China Unicom, China Telecom and China Tower in 14 provinces and cities such as Beijing, Shanghai and Guangdong, and the network optimization maintenance team of the operator Also showed strong concern.
At the same time, the system is also applied in the venue of the 2016 G20 Summit in Hangzhou. The office building of the Outskirts Procuratorate in Wuhan, the South Commercial Plaza in Central and Southern Changsha, and the Guangzhou Lying Commercial Complex have been applied.
"The design of the MIOTSS system can both serve the dual-loop indoor distribution system of a new project and can also be used for retrofit projects in older projects that account for more than 80% of the market. Therefore, the potential of a new construction project plus retrofit projects Is on the scale of hundreds of billions. "Wang Jianguo is very optimistic about the market prospects of intelligent management subsystem.
Secretary-General Yang Hua proposed that the next industry chain should establish a joint laboratory to promote technology and standardization work to promote the indoor distribution system to enhance the level of intelligence and rapid maturity of the industrial chain.
