The G in 5G means that it is another generation of wireless technology that will provide us with faster speeds and promote economic, infrastructure, work, VR, telemedicine, driverless cars and other areas. Everyone wants to use 5G as soon as possible, but the time to achieve widespread deployment is much longer than we think. Let's follow the small series to check out some of the hottest topics about 5G technology discussions. First, 5G equipment Before the replacement to the 5G device, the initial connection needs to be made through 4G. And all 5G super phones still need to use 4G technology. But at present, there is no 5G smartphone on the market, and when the 5G smartphone is actually listed at some time in 2019, the extensive 5G network is not yet ready. Second, 5G will replace Wi-Fi This statement is purely nonsense. In 2019, Wi-Fi will account for more than 50% of total IP traffic on mobile and Wi-Fi devices. Wi-Fi requires intensive deployment, and 5G technology also requires intensive deployment. But Wi-Fi will continue to work for a long time. Third, the time of large-scale deployment has not arrived As the two most influential countries in the world, China and the United States will not implement commercial 5G services as early as 2020, so there is no need to worry. Relevant regulatory policies are still being developed. The US Federal Communications Commission has prepared for the deployment of 5G services in 2020, and for a number of reasons, China's 5G adoption process will be slower. The UK completed its first round of spectrum auctions in April 2018, and the UK operator O2 also conducted some small-scale trials, but it will not achieve large-scale 5G coverage until 2022. Fourth, the cost of the problem Operators have spent billions of dollars building 4G networks to make a profit, and the cost of 5G is expected to be higher. They know the high cost, so they want to ensure the investment prospects of the technology. Consumers are expecting better coverage, more data and lower prices. But operators are not concerned about these expectations of consumers. V. Infrastructure There is still a long way to go before the establishment of the 5G standard. Related tests are in progress and 5G mobile phones are in production. One of the challenges faced by higher frequency signals is that they are not as far away as the lower frequency signals, so multiple input and output antennas (MIMO) are needed to boost the 5G signal. The transition to 5G represents a new receiver for the new wavelength. Related tests are ongoing and experiments are performed using 16 antennas to ensure that at least some of them are capable of receiving 5G signals. Depending on the environment, due to cost reasons, operators cannot always have enough antennas in all locations. Who will benefit from 5G The first to benefit will be the next wave of technologies, such as autonomous vehicles, smart factories, smart cities, virtual and augmented reality, edge computing, and medical Internet of Things. The indisputable fact is that 5G is very fast and will bring huge potential and business opportunities, but it will not be realized soon, and it will certainly not be realized in 2019.
