In the field of mobile communications:
The first generation is analog technology;
The second generation realized digital voice communication;
The third generation is the well-known 3G technology, characterized by multimedia communication;
The fourth generation is the 4g technology that is being rolled out, and its communication rate is greatly improved, marking the era of entering the wireless broadband.
G is an abbreviation of the English word GeneraTIon (for the X generation). Therefore, 5G is the fifth generation mobile communication technology.
To date, mobile technology has evolved from a "people-to-people"-based platform (3G) to a "people-to-informaTIon" connection (4G) at the global scale. 5G not only needs to be human-oriented, but also utilizes and expands the past research and development and capital investment for mobile technology, and promotes mobile technology to become a popular, low-latency and adaptable platform to meet future usage needs. 5G will support new cutting-edge applications, promote business innovation and stimulate economic growth. The emergence of 5G is a fulcrum that has evolved mobile technology from a technology that has a transformative impact on personal communications to a truly universal technology that is expected to change the industry and economy as a whole.
Whether it is mass Internet of Things, business-critical control or enhanced mobile broadband, these three areas have gone beyond the use of smartphones, expanding the application of 5G to a broader space. In addition to speeding up personal wireless communication services, 5G will also affect 21 industries in these three areas, including enhanced digital signage, smart agriculture, smart cities, self-driving cars, drones, etc. (IHS Markit "5G How to influence the economy"). This means that 5G networks will connect with more smart devices and industrial devices than just consumers' smartphones.
The difference between 5G network and 4G network
1. First and foremost, the LTE-based 4G network is experiencing a rapid deployment, while the 5G network is currently only in the research report and implementation project phase, and the latter's large-scale deployment is expected to wait until 2020.
2, 4G and the previous mobile network mainly focused on the provision of raw bandwidth, while 5G aims to provide ubiquitous connectivity, laying the foundation for a fast and flexible network connection, whether the user is in a skyscraper or a subway station.
3, 5G network does not exist independently, it will be a combination of multiple technologies, including 2G, 3G, LTE, LTE-A, Wi-Fi, M2M and so on. In other words, 5G was originally designed to support a variety of different applications, such as the Internet of Things, networked wearables, augmented reality and immersive games.
Unlike 4G, 5G networks have the ability to handle a large number of connected devices and traffic types. For example, when dealing with high-definition video online playback tasks, 5G provides ultra-high speed links. When faced with a sensor network, it will only provide a low data transfer rate.
4, 5G networks will be the first to use a new architecture such as cloud RAN and virtual RAN to promote the establishment of a more centralized network and maximize the use of server farms through localized data centers at the edge of the network.
5. Finally, 5G will also take the lead in using cognitive radio technology to allow the network infrastructure to automatically determine the type of band to be provided, to distinguish between mobile and fixed devices, and to adapt the current situation within a specified time. In other words, 5G networks can serve both industrial networks and Facebook applications.
We all know that curved-edge phones look good, but they are not easy to protect. In order to prevent the mobile phone from being scratched, current mobile phone users like to stick a phone Screen Protector on the mobile phone screen.
With the development of the market, more and more users like mobile phones with curved screens. Unlike flat mobile phones, the screen protectors of curved screen mobile phones are not easy to buy or stick. The main reason is that the Tempered Glass Screen Protector of curved mobile phones is difficult to fit the height of the mobile phone screen. Then our TUOLI Uv Screen Protector is the best choice for full screen users.
Using the curing principle of the 30 UV lamp beads of the UV Curing Machine to scan the entire screen, the UV Screen Protection Film has the texture of tempered glass. The upper limit of the high temperature of the UV Machine is 60 degrees, has a good heat dissipation function, and has a time setting: 180 seconds. Exquisite and easy to operate, it can make the Screen Protective Film have high light transmittance and smoothness.
