Where will broadband go after 5G popularization? The result is different from what you think
With the development of science and technology, we use the network faster and faster. In 2019, many people call it the "5G first year". Why did the previous network updates go unnoticed, and this 5G everyone is so concerned? The main reason is that 5G is too obvious for network speed improvement. In theory, 5G will be 100 times faster than 4G. Now the download speed of 4G network can reach about 4MB/S. That is to say, the download speed of 5G network is about 400MB/S. It only takes three seconds to download a GB movie. This is beyond the reach of many families'broadband. Where will broadband go when 5G era comes? Why?
Most of the broadband we currently use is 100M. The theoretical download speed of 100M broadband is 8MB/S, and the speed of 5G will undoubtedly exceed 100M broadband, but many people think it is too simple to replace broadband. First of all, broadband is the signal transmitted by the line, and 5G is the signal tower. The charging time of the two is different. We can use broadband freely after a month. But mobile Internet access should be calculated according to the flow rate. The "infinite flow card" thing does not appear now. In the 5G era, it will not appear. 5G signal replaces broadband. We can not use it.
In addition, many people still underestimate the ability of optical fiber broadband. In fact, gigabit optical fiber has been realized very early, just because the cost is too expensive and has not been popularized, the speed of broadband is not as fast as 5G, but few people use such fast broadband. Under the impact of 5G network, broadband upgrade and cost reduction has become inevitable. Operators are not willing to replace 5G broadband lines laid over the years, and the lines are certainly much more stable than 5G base stations.
What's more, 5G speed is fast, but there are always places where 5G can't reach. The current 4G signal is the same. When we are in the elevator, sitting on the high-speed railway, driving into the tunnel, we can't actually receive the mobile signal. How can we get online at this time? It's through broadband routers, of course. And people have become accustomed to using wifi. Can hotels not support wifi?
