China's government has repeatedly confirmed that 5g will be commercially available in 2020. Now, various technologies for 5g have been rapidly warming up, and many technical solutions have been gradually implemented.
How much do you know about 5g? What the hell is 5g? What is 5g? The fifth generation mobile phone mobile communication standard, also known as the fifth generation mobile communication technology, foreign language abbreviation: 5g. It is also an extension after 4G. Under study, the network speed can reach 5m / s-6m / s. 5g is simply summed up as four sentences: low power consumption, high speed, low time delay, interconnection of everything.
High speed: on the basis of 4G, the online speed can be increased by 100 times to 20gbps per second. Speed up is very valuable for technology and industry. Such a high speed, on the one hand, means that the spectrum utilization rate has been greatly improved. On the other hand, it conveys that some spectrum that was previously considered impossible to have commercial value can be used as mobile communication, which greatly improves the ability of human beings to develop mobile communication resources.
Internet of everything: in the era of voice as the core, the number of links supported by mobile communication is very limited. Now, China's base stations only support about 1.2 billion terminals, that is, each person has one or two terminals. In the 5g era, each person may have five or even 10 terminals, and the number of devices linked into each base station will increase five or even 10 times. A large number of scientific and technological products will be connected to the network. This means that in the 5g era, the concept of Internet will be completely forgotten, and networking is the norm. A large number of scientific and technological products will always be connected to the network, providing all kinds of valuable data, and becoming the basis of the intelligent Internet.
Low delay: for the user's command, 5g needs to reduce the response time of the base station as much as possible. Many users are used to waiting when they use computers to access the Internet and use mobile phones to make calls. However, for intelligent services after 5g, the requirements are totally different. It is used to support navigation. When the response is slow at an intersection, the user may cross the intersection and turn around. It will take a long time. Especially in the intelligent transportation system, all vehicles are managed through the central control center. A one second delay can lead to a series of car crashes. Therefore, low delay is a problem that 5g must solve.
Low power consumption: a large number of intelligent wearable products released this year, the basic idea is to connect through a mobile phone, and then communicate with the base station by the mobile phone, and send data to the Internet. These products are almost impossible to connect with base stations. Because today's base station is mainly to solve voice communication, even data is to do faster and faster, high power consumption is natural. But in the future, many technology products need to establish new channels to communicate with the base station. These channels do not provide high speed, but can provide low-power data communication at low speed. The emergence of 5g can solve this problem.
5g strong attack, so what impact does this have on the crystal oscillator industry? We all know that the current technology is inseparable from the use of electronic components, which has led to the development of many electronic products, including crystal oscillator. Quartz crystal oscillator plays a key role in communication equipment and is widely used in various time display and time control products.
The reason why 5g communication can achieve such amazing progress, including the use of chip crystal oscillator, 2016mm, 2520mm ultra-thin ultra-small chip crystal oscillator is most suitable for the mobile communication field such as the reference clock of mobile communication terminal. SMD crystal oscillator has the frequency of reference clock source for all kinds of mobile communication. SMD crystal oscillator has excellent electrical characteristics. Its environmental resistance is suitable for the field of mobile communication and meets the requirements of high temperature reflow temperature curve of lead-free welding.
