Technological innovation, radio management ushered in a new situation
The independent innovation of wireless communication in China for 20 years not only makes China's wireless communication become a global leader, but also makes China's radio management business flourish. With the acceleration of the number of modules, the emergence of new formats such as Internet+ has also brought radio management into a new normal.
Lu Gongchao, director of the Beijing Radio Administration Bureau, said that with the development of China's radio industry for many years, especially the success of a batch of communication standardization industrialization with independent intellectual property rights, China's wireless communication development has reached a new level.
However, with the advancement of technology, wireless communication applications are becoming more and more extensive, and China's radio management is also facing a new situation. For example, spectrum resources are scarce, broadband cluster bandwidth demand is strong, etc., which requires China's radio management to continue to open up, innovation and win-win to achieve the new normal radio management.
Carrying on the past: private network communication to meet the new normal
Undoubtedly, private network communication has always played a vital role in China's economic and social development, people's life and stability.
However, with the rapid development of China's economy and society, people have put forward new demands and new expectations for private network communication. People are no longer satisfied that private network communication can only be heard and heard clearly; they also want to see and see clearly.
For example, Lu Gongchao said that the McWiLL private network previously built in Beijing was built by Xinwei and provided equipment. Beijing Gehua operated. In the more than 10 years of its operation, the technology and equipment performed well and completed various tasks. task.
With the rapid development of global broadband trunking communication and the establishment of a government-specific private network in Beijing under the new situation, a new generation of broadband band group solutions based on TD-LTE technology has begun to emerge, especially the B-TrunC (Broadband Cluster) Industry Alliance. The establishment of this process has accelerated this process. The B-TrunC system has high spectral efficiency, low latency, and support for voice and multimedia cluster services, which can meet user needs.
In addition, the standard is also internationally recognized. In November 2014, the sixth plenary session of the ITU-R Study Group 5 of the International Telecommunication Union Radiocommunication Bureau reviewed and approved the revised version of the M.2009 Recommendation submitted by the WP5A Working Group, “Broadband Cluster Communication Based on LTE Technology (B -TrunC) System Interface Technical Requirements (Phase 1) Air Interface" is written in Recommendation M.2009, which identifies the B-TrunC system air interface officially becoming the ITU-R recommended PPDR (Public Protection and Disaster Relief) broadband cluster air Interface international standard.
New situation: innovation, cooperation and win-win situation can seek development
With the growing demand for broadband cluster construction, the creation of local government private networks has brought about new changes in China's private network market. Not only have cluster providers continue to increase, but the local government's private network construction model has also undergone major changes. The innovation of construction mode and the cooperation and win-win of cluster industry have become the main theme of the new era.
According to Lu Gongchao, the emergence of TD-LTE-based broadband clusters has enabled traditional public network equipment providers to enter the private network. For example, Huawei and ZTE have successfully entered the special network through public network. The online market, this will undoubtedly further enrich the private network market, making the competition in the private network market more reasonable and making users more selective. At the same time, due to the unification of broadband cluster standards, it enables devices from different vendors to adapt to each other and change the status of traditional cluster vendors. We can cooperate and innovate under the same standard platform, so that China's broadband cluster industry will further expand. Be strong and achieve a win-win situation.
The demand for large-bandwidth spectrum in the broadband cluster system has also changed the network construction mode built by the original departments. The model of a government-specific private network in the city is being recognized.
Lu Gongchao used the Beijing Municipal Government Affairs Network as an example. The Beijing Municipal Government Special Network created the model according to the whole city's one network. All departments realized communication on this special network. The private network runs on the 1.4G frequency band and has 20M bandwidth, which not only saves a lot of spectrum resources, but also complete 20M bandwidth to meet all the large bandwidth service requirements, such as video and big data file transmission.
In addition to a government-specific network model, Beijing Government Affairs Network also has a new construction and operation management model. Lu Gongchao said that the traditional government private network construction is carried out by the government itself for tendering, construction, operation and maintenance. However, the government's main business is not the operation and maintenance of the private network, which has caused various situations in the operation of some private networks. In order to avoid the emergence of these problems, the Beijing Municipal Government Special Network has adopted a third-party model for the operation and maintenance of the first letter, and the purchase of services in Beijing.
The professional business is handed over to the professional company operation management to undoubtedly maximize the efficiency. At the same time, the purchase service model also greatly reduces the government's initial investment. It is understood that this model is currently being promoted to the whole country. However, in this regard, Lu Gongchao hopes that in the future, operators such as Capitel will be able to do more, so that the industry will be more competitive under the premise of guaranteeing profits. So that the industry can achieve healthy and healthy development, so that all parties in the industry can achieve a win-win situation.
The main function of the Solar Energy Storage System is to store the electrical energy generated by the solar panels so that it can continue to supply electricity when the solar panels cannot generate electricity or when the demand for electricity exceeds the supply of the solar panels. It is an energy storage solution for improving the self-sufficiency and energy efficiency of solar power generation systems.
Main effect:
Energy Storage: The Solar Energy Storage System uses batteries to store excess electricity generated by solar panels. When solar panels generate more power than needed, the excess power is stored in batteries to continue supplying power when needed.
Power supply backup: When the solar panels cannot generate enough power, such as at night, in cloudy, or in bad weather, the Solar Energy Storage System can use the stored power to continue to supply power to ensure the continuity and stability of the power supply.
Energy Balance: The Solar Energy Storage System helps to balance the energy difference between the electricity generated by solar panels and the electricity demanded, thus optimizing energy management and maximizing self-sufficiency.
Differences from other energy storage systems:
Power source: The power source of the Solar Energy Storage System is a Solar Panel, which directly generates electricity by converting sunlight. While other energy storage systems may come from other renewable energy sources, such as wind energy, hydro energy, or non-renewable energy sources, such as grid electricity.
Renewability: The Solar Energy Storage System uses solar energy as a power source and is a renewable energy system. Other energy storage systems may utilize different types of energy sources, with varying degrees of renewability.
Application scenarios: Solar Energy Storage System is mainly used in photovoltaic power generation systems, especially in conjunction with solar panels. Other energy storage systems can be used in different energy generation systems, selected according to specific energy sources and application requirements.
Overall, the main function of the Solar Energy Storage System is to store the electrical energy generated by the solar panels for continued power supply at night or when the solar panels are unable to generate electricity. Compared with other energy storage systems, it uses solar energy as a power source, is a renewable energy system, and is mainly used in photovoltaic power generation systems to improve energy utilization efficiency and self-sufficiency.
