The 5th generation mobile networks, also known as 5G. It has become a hot topic of discussion in recent years. Internet speed is as fast as one second to download a high-definition movie. No longer need to wait for buffering when surfing the Internet. Although 4G has changed the way people live and travel, making our lives more convenient, but with the development of mobile communication technology. 5G, the new age of 5G communication will overturn our lives and open a new chapter of the Internet once again. At present, China's 5G commercial use has started, and communication service providers have also successively launched their own service plans. Many lucky people have enjoyed 5G's ultra-fast network already.
With the developing of 5G, smart wearables, AI robots, VR devices, autonomous driving, intelligent medical care devices, and voice communication will be further integrated into our lives. 
The arrival of 5G not only improves the network speed by a hundred times, but also makes it possible to interconnect everything, making our lives smarter. Everyone may have 5 or even 10 terminal devices. The equipment connected to each base station chain will increase by 5 times or even 10 times. A large number of technology products will be connected to the network. This means that in the age of 5G communication, the concept of Internet access will be completely forgotten, and networking is the normalcy, and a large number of technology products are constantly connected to the network to provide various valuable data. Becoming the basis of the intelligent Internet. Faster networks require higher performance equipment and more demanding components. So what role does crystal play in this 5G industrial revolution?
Crystal is the core electronic component in 5G technology. Its role is to provide high-end reference clock signals and receive transmission signals. 5G technology must be very accurate and efficient in all aspects, so the requirements for the crystal oscillator will be as high as possible. Passive crystals are the most widely used at present, but difficult to provide stable frequency output. In addition, 5G-related products require higher fundamental frequency crystals. Due to their own limitations, ordinary passive crystals must be equipped with higher stability and more accurate active crystals to make 5G devices work better. The active crystal oscillator has a built-in clock circuit, which can provide a more stable output frequency and make the circuit work more smoothly.
The age of 5G communication, There are huge demands for crystal oscillators in base stations, smart phones, servers, electric power, Automotive products and other fields. As the "heart" of electronic products, crystal oscillators must also be continuously upgraded to meet the higher requirements of 5G network equipment.
