Today I want to talk to you about the hot topic of 5G. Recently, Sun Wei, a professor at Beihang University, angrily tore the 5G fig leaf in a speech, which attracted the attention of many people. He believes that operators force users to buy 5G packages by reducing the speed of 4G networks, which is an unreasonable business method. In addition, he also raised a question: which software 4G cannot be used now, only 5G can be used? If not, then what do we do with 5G?
These points got me thinking. Indeed, most mobile applications can run smoothly under the 4G network, so why upgrade to 5G? In addition to some special application scenarios, such as VR, AR, etc., ordinary users do not have much demand. Moreover, the coverage of 5G networks is relatively low, and only 4G networks can be used where the signal coverage is not available.
At the same time, we must also see that it takes a long time for new technologies to emerge and apply. Just as trains have gone decades from invention to mass use, 5G needs a process. We can't expect full coverage and adoption overnight. In addition, the construction and promotion of 5G also requires huge investment, which is also a factor that operators need to consider in the process of promoting 5G.
Of course, 5G also has its advantages. It has faster transfer speeds, lower network latency, can support more device connections, and provides a better infrastructure for some emerging applications. For example, future smart homes, autonomous driving, industrial Internet, etc. all need 5G support.
In general, 5G as a new technology, its application and promotion will take time and process, we cannot expect it to replace 4G to become mainstream all of a sudden. At the same time, we should also take a rational view of operators' business methods, and not allow ourselves to be "forced" to upgrade to 5G. We should choose whether to use 5G networks according to our own needs and actual conditions.
In addition, I would like to say that what Ren Zhengfei said is very correct: "The value of 5G is in the future, not now!" "We need to be patient and let 5G play a greater role in the development of the future."
In addition to the points mentioned above, I think we also need to pay attention to some potential problems with 5G networks.
The first is the security of 5G networks. As 5G technology continues to evolve, so does the risk of cyberattacks and data breaches. 5G networks are more complex and widespread, which means attackers can more easily find vulnerabilities and attack portals. In addition, the larger amount of data in 5G networks and faster data transmission speeds mean a higher risk of data leakage. Therefore, we need to strengthen the security of 5G networks to prevent the risk of cyber attacks and data leaks.
The second is the electromagnetic radiation problem of 5G networks. With the promotion of 5G networks, more and more people are beginning to pay attention to the impact of 5G networks on human health. 5G networks require more antennas to achieve wider coverage, which means more electromagnetic radiation. Although there is not yet sufficient scientific evidence that 5G networks are harmful to human health, we still need to pay attention to this issue and conduct more scientific research and monitoring.
In addition, the construction and maintenance of 5G networks also requires huge investment and human resources. Although 5G networks can bring us more convenience and development opportunities, we also need to consider the cost of 5G network construction and maintenance. Operators need to invest a lot of money and human resources to build 5G networks, but also need to maintain and upgrade. This means that users may have to pay higher network fees, and operators need to bear higher cost pressures.
Finally, we also need to consider the impact of 5G networks on society. The popularization of 5G networks will bring more opportunities and challenges, which will have a profound impact on the industrial structure, labor market and social lifestyle. We need to actively respond to these impacts and take measures to ensure the healthy development of 5G networks.
In summary, as a new technology, 5G network will take time and process to apply and promote it. We need to take a rational view of the advantages and disadvantages of 5G networks, and also need to pay attention to the security, electromagnetic radiation, cost and social impact of 5G networks. Only on the basis of comprehensive consideration of these factors can we better promote the development and application of 5G networks and bring more opportunities and benefits to our lives and development.
