After the popularization of 5G, will fiber-optic broadband withdraw from the historical stage now?

After the popularization of 5G, in order to replace light, the following conditions must be met:

1, the network speed can reach more than gigabit. At present, domestic broadband is basically 100 megabits to 200 megabits. A few years later, with the popularization of 5G, domestic optical fiber will inevitably reach Gigabit. If the network speed of 5G is slower than that of optical fiber broadband, then it cannot replace optical fiber.

2. Realize super-large flow or unlimited flow. Home optical fiber is used by many people because there is no flow limit. You can download it within 7×24 hours if you like. However, data networks usually have traffic limitations. For example, the 4G we are using now, when it reaches 20GB or 40GB, the speed will be limited, and when it reaches 100GB, the network will be disconnected.

Now a Blu-ray HD movie costs 40GB, and a fun 3A game costs more than 100GB. Then if there are so many restrictions on the traffic of 5G, there is definitely no way to use it normally. Unless 5G traffic can at least achieve 1000GB traffic per month, it is impossible to replace fiber-optic broadband.

3. Tariffs must be reasonable. Fiber-optic broadband has been developed for so many years, and the price is already very cheap. 100M telecom broadband is less than 1000 yuan a year. Not long ago, Mobile even gave free broadband to old users. At present, some provinces, such as Jiangsu, have started the trial of gigabit fiber-optic broadband, which costs more than 200 yuan a month, which is not expensive. And if the price of 5G traffic exceeds that of optical fiber, then there will definitely not be too many people willing to use it.

4. Safety must be guaranteed. At present, home fiber-optic broadband is to dial through the cat first, then connect the home router, and finally connect various terminals such as mobile phones. In other words, there are at least two layers of security protection between the home WiFi and the external network. Although people may not feel it at ordinary times, devices such as routers also play a role in protecting network devices such as mobile phones from intrusion.

In the future, if computers, mobile phones, televisions and other devices at home are directly connected to the 5G network, there will be no protective barrier between them and the external network, which may lead to the disclosure of personal privacy data. Therefore, after the popularization of 5G, how to ensure the safety of Internet devices is also a difficult problem.

5.5G smart devices must be popularized. 5G is not only used for mobile phones and computers to surf the Internet. In the future, home appliances such as televisions, refrigerators, washing machines and water heaters may all have built-in 5G chips to connect with 5G networks. This is the real role of 5G-the Internet of Everything. When all smart devices use 5G chips to access the Internet, it may really be time for home broadband to quit the historical stage.

All in all, it is indeed possible for 5G to replace fiber-optic broadband in the future, but this first requires 5G speed increase and tariff reduction. If 5G is still the same as the current 4G, it is empty talk to replace broadband.
