Samsung 5G Technology meets challenges: terminal hardware and network bottlenecks

Tencent Science and Technology (Tom) Beijing time May 14 news, according to foreign media reports, South Korean Samsung announced recently, the company has successfully developed the first 5G core technology based mobile transmission network, which means that mobile phone users in less than a second time to complete a high-definition film download. In this respect, the well-known "time" magazine special writer Matt Parkham (Matt Peckham) recently on the author of Samsung's technology has been analyzed. Parkham that Samsung's 5G technology hype is overblown in the context of today's infrastructure and services, and it is unclear whether the technology will be able to resolve some of the current fatal flaws before it is commercialized in 2020. The following is the main content of the article: Samsung Electronics recently announced that the company has successfully developed the first 5G core technology based mobile transmission network, is expected to be in 2020 before the 5G network business promotion. Samsung said the 5G network uses a millimeter-wave technique, with 64 antenna groups overcoming obstacles to the spread of many negative signals and successfully achieving the target of transmitting more than gigabytes per second over a two-kilometer distance. It is reported that Samsung 5G Technology has successfully reached the 1Gbps transmission rate at 28,000 MHz (GHz) band. By contrast, the current popular 4G LTE service transfer rate is only 75Mbps. Moreover, the maximum transmission rate of the future 5G network will reach 10Gbps, which means that mobile phone users are expected in less than a second time to complete a high-definition movie download. When people see this news, it is believed that most of the reader's first reaction is excitement and anticipation, and looking forward to the 5G network may be brought about by the convenience of their lives. But after the excitement, it's not hard to see that the service still has a lot of unresolved problems, and faster network speeds are exacerbating these problems. Network load saturation For example, imagine that you are currently driving on a 80-mile interstate, but considering the limited lanes, actual traffic flow, and one fork at a time, your actual speed is about 40 miles, In this case we can also often in the smart phone in the campus area of the actual speed of the internet has been reflected. For example, when we connect to a network at a well-known game, holiday or recess, we often find that our network speed is far below the operator's theoretical data. The problem, therefore, is not that my smartphone has a 4G network fast enough (even 3G networks can smoothly play streaming media files from Netflix or Spotify), but because the mobile towers I use are overloaded with too many people. To be sure, mobile operators are now trumpeting their rising price of unlimited traffic data packages in the hope of maximizing profits from existing customer base. However, with the increasing number of users and the continuous development of faster mobile communication technologyRipe, the network pressure of the mobile operator is almost saturated, and it begins to affect the user's actual experience. The bottleneck of hardware technology in addition to the network load capacity of operators, faster network services also face some other problems. A few weeks ago, when I was waiting in the parking lot, a friend of mine sent me a video link and I clicked on the link and looked forward to a video clip like YouTube. However, after clicking on the link, my phone's browser was stuck for a few seconds before it was forced to shut down. Then I clicked on this link again, but the situation is still the case, but I have to give up. Soon after, my phone began to receive SMS alerts from operators, the first text message is "My month mobile data has been more than 50%", and then I received a second, third text message to remind me that data flow usage has been more than 75% and 90%. Under the feeling of being nasty, I can only reset the phone and call the operator immediately and ask them to investigate the situation clearly. Finally, I realized that the link my friend sent me was actually a very large volume of video content, but because my phone did not recognize the video format, the video's loading process was entirely in the background. When I clicked on this link, my phone actually started to receive a lot of video data, so it consumed my data package traffic. Through the events of my personal experience, we can see that people have a lot of problems when they have a faster internet connection. For example, if people do not close the mobile phone back-end program in time, it is possible to pay an expensive price. I always think that as long as the people in the hands of intelligent equipment storage space is still very limited, mobile operators Network load capacity is still saturated, the continuous discussion of mobile network data connection speed is meaningless. So I hope that companies such as Samsung will be able to reduce the discussion of building faster networks over the next 6-7 years, but more focused on solving network load and traffic anomaly detection. It should be noted that if today's 3G networks can be consistently connected, I don't mind letting devices such as my smartphone, tablet, and laptop use this network until 2020.
