The Internet is tapping into the traditional world at one point. Computers, mobile phones, TVs, and cars now go to the home. In the mobile Internet field, with the continuous improvement and improvement of more and more devices and technologies, the home industry is an industry that is closely related to people's life at all times. Naturally, the Internet cannot spread. In fact, smart home is not a new concept. Before the Internet, smart buildings, Smart Security, and smart buildings were avail

Front-end image acquisition is now evolving towards high-definition and digital; Image Storage and image analysis are evolving towards distributed and intelligent development; and image transmission technology is also evolving towards multi-network convergence. From both the overall technological development trend and the results of market competition, Image Transmission Technology fusion is an inevitable trend. Camera digitalization also lays the foundation for the int

+ and 5G can be clearly defined. The performance of Pre 5G obviously exceeds the 4G + standard definition, but it does not need to depend on the standard definition of 5G. It can only be implemented based on the Standard 4G. Therefore, even if there is no Pre 5G phase in the standard, a Pre 5G phase between 4G + and 5G will also appear at the implementation level. Some people may be skeptical about the 4G era and the intermediate stages before the arrival of 5g. However, the latest Ericsson mob

in the next few years. ATT spokesman Mark Siegel MarkSiegel did not disclose how many users will be migrated to the new network. ATT said: "We hope this transition will not have a major impact on the company's operating performance, however, the impact of migrating users from 2G devices to 3G devices or 4G devices on financial conditions will continue to be evaluated." ATT's move to shut down its traditional 2G network is to keep up with the pace at which other operators replace the original
