| "4G network attacks, your old mobile phone can Hold live?" in the morning to the company to open the computer will see this information. Reported that now, China Mobile 4G TD-LTE network layout basically completed, it is expected, then the speed theory will be higher than the 3G network six times. Then, 4G struck, crystal again change far? Therefore, Jin Luo electronic mentioned 4G the arrival of network innovation once again the electronics industry will expand, crystal industry will usher in a new development.
4G is the fourth generation mobile communication and its technology. Compared with the traditional communication technology, 4G communication technology is the most obvious advantage of call quality and data communication speed. It is another wireless communication technology leap after the third generation.
In developed countries, the popularity of 3G services more than 60%, then this time will need to update the system to further enhance the quality of service. Once again, the electronics industry innovation will begin, crystal industry will usher in a new development.
Recalling the development of mobile phones, from the first generation analog communications technology to the second generation digital communication technology (2G), and then to the third generation (3G) mobile communication technology, communication technology has been rapid development in recent years. In particular, the expansion of 3G mobile phone functions, but also increased the number of electronic components, devices. The increase is not only the number of crystal, crystal performance has also further requirements, how to adapt to the requirements of 3G mobile phone technology to mobile phone support, is a lot of crystal manufacturers need to face the challenge, but it is also a good chance. It can be said that one of the important reasons which also prompted the crystal industry transform. 3G era has matured, 4G network will step into our life, it will give the various industries what kind of impact?
In order to make full use of the advanced service 4G communication brings to people, also must use a variety of terminal 4G to realize, before there are many communication operators in 3G communication has been a huge success, with the arrival of the era of 4G communication, they immediately to look at the production of 4G communication terminal products. The 4G license has not been issued, 4G intelligent mobile phone has come out, with the latest news: "4G LTE has started a pilot in some areas of the country, the China Mobile 4G LTE smart mobile phone has storage, the upcoming sale". There is no doubt that the 4G intelligent mobile phone also need to use the crystal, gold Luo electronic 3G iPhone need to use mobile phone 5 is two quartz crystal, do not know what there is a need to use the new 4G intelligent mobile phone in the crystal?
In the field of mobile communication, the constant temperature controlled crystal oscillator OCXO is the core component of 3G, it is mainly to provide the synchronous signal source of network communication. With the gradual expansion of the 3G infrastructure, the demand for high-end OCXO will continue to grow. With the arrival of the era of 4G communication, high precision, small size of crystal, such as high precision temperature compensated crystal oscillator TCXO products on the market, will also usher in a new development opportunity. Then, the crystal industry will enter the development stage of the high speed.
