Why is ADSL bandwidth "Narrowing?

ADSL should have brought you a fast Internet access speed, but with the monthly subscription or "5400 yuan for 5400 hours of Internet access fees, free fashion computers "! With the launch of this preferential policy, everyone is riding on the "Broadband Express ". However, as the number of people increases, ADSL is becoming increasingly congested. I would like to know the reasons and how to solve them. Is it a technical reason or something else? The reporter asked related experts with questions.

According to experts, according to the modulation mechanism of ADSL, there are three reasons for broadband being not "wide": 1. line problems (telephone lines); 2. device problems; 3. outbound bandwidth sharing. There are also other causes, such as abnormal user usage and MODEM used by China Telecom. Because of the different LAN mechanisms used by ADSL and Great Wall broadband, the reason why ADSL is more complicated than Great Wall broadband. In fact, all the users on ADSL say that the implementation of the monthly subscription system is much slower, but there is a misunderstanding here.

How can we solve the problem of ADSL? It is not possible to maintain and select routes in short-term Internal Medicine. Simply put, for example, we usually use roads and vehicles to describe data transmission. There is no problem with the backbone of the road, China Telecom, and it is no problem to extend down to the main roads in various regions (of course there are some improper places), but it is complicated to go down from the intersections in various regions, for example, a large number of ADSL connections, problems affecting ADSL line communication, user usage problems, and terminal problems may cause users to feel slow. There are two major causes of ADSL Slowdown: line problems and device problems. The solution is divided into two aspects: first, the overall use of the line needs to be checked to check whether there is interference, to remove interference sources, the use of telephone lines and external lines is a strange situation. Generally, telecommunications is a line change until wireless networks can be changed. The formal solution is of course the use of standard twisted pair wires. Second, the bandwidth of the local network device port is adjusted. However, for the modulation method, China Telecom needs to invest a lot of money, and both local and client devices need to be replaced. Currently, this is unlikely.
