Crystal oscillator industry will benefit a lot from the establishment of smart city in the future. The emergence and popularization of smart appliances have brought us too much enlightenment. In the future, the interconnection of everything will gradually deepen. Now this technology is also extended to warehouse management and industrial park management. In the future, a smart city management system will be established, especially with the deployment of 5g. Indeed, the demand for quartz crystal oscillator will be greatly increased in the future, Especially for the crystal oscillator products used in some network communication modules, it will be another competition place for the majority of manufacturers.   
    The birth of the concept of smart city stems from the social problems faced by cities all over the world, that is, the increase of the population migrating from rural areas to cities is the same as the sudden increase of the population in cities and towns in Asian and African countries. It is predicted that by 2050, about 6.7 billion people, accounting for 68% of the world's population, will migrate to cities and towns. What problems will the growth of urban population bring? It is easy to imagine the traffic jam of cars, the increase of exhaust emissions, and the shortage of energy such as electricity and gas In addition, the inability to accept satisfactory medical services and the fact that the city is full of garbage are also expected, and the city is likely to fall into a crisis of abnormal operation.

    In the context of the above social problems,The idea of using the Internet of things to manage the whole city and enable it to operate smoothly, efficiently and unimpeded came into being. For example,By alleviating traffic congestion, it can not only make the traffic more smooth, but also eliminate the need to add roads. By using the water pipe network system to detect abnormal phenomena such as water leakage,The most suitable repair and replacement can be carried out In other words, smart cities are not only beneficial to the convenience of life and environmental protection, but alsoInvestment that can reduce infrastructure can be carried out, bringing greater economic benefits. This is the ideal form of the future city described by the smart city. The biggest premise for the realization of wisdom is ubiquitous and fast network communication. The main function of establishing a transportation hub for data transmission is to realize data transmission. For example, 5g, a fast communication technology using quartz crystal oscillator as clock source is very suitable; Of course, artificial intelligence and data analysis are essential,The function of these two technologies is to analyze the situation at the first time and quickly put forward solutions to decision makers For example, optimize bus and tram services, reduce labor costs, or analyze the overall traffic flow of the city and propose routes to alleviate traffic congestion.

    Of course, these are some core technologies. You can't imagine how many devices are used in this large-scale construction. We need switches, servers, countless routers, and even a few cameras, sensors, radar, etc. for these devices, quartz crystal oscillator is necessary, Not to mention their performance requirements for crystal oscillator products, patch packaged products are bound to be used, because this can effectively reduce the volume of the equipment. For such systems that need to work continuously, it is best to choose low-power products to provide clock sources, mainly to reduce the power consumption of the equipment.
