Domestic operators have frequent network failures, and those who once ridiculed Europe and the United States were ridiculed
Guangdong Mobile due to the network disconnection caused users can not call mobile phones and mobile phones, while users can access the Internet normally, this serious failure has been more than two hours, it is said that it has been hit harder than any in the past, why does this always happen to operators?
In fact, network failures are not uncommon, with China Telecom's branches in Shaanxi and Gansu having network problems, as well as Beijing Mobile, indicating that the incidence of network failures is much higher than in the 2G and 3G eras.
Looking back at the problems with the communication networks in Europe and the United States, comparing the two, will we still openly ridicule the problems of the European and American networks?No matter who the device is, the reliability of the network is very difficult, without any problems, the current network is very complex, and the device of a system can rarely be like the 2 G, 3 G network, to ensure that their network will not be as reliable as 2 G, 3 G.
Taking the network as an example, at present, China Mobile has 2G, 4G and 5G networks, China Telecom has 2G, 4G, 5G, 2G, 3G, 4 GMA, 4G 4G network, 4G is TD-LTE, 3G is LTE, CDMA2000, 4G is TD-LTE, LTE-FDD, China Unicom and China Telecom are building 5G base station networks, each with its own operating system. China Unicom and China Telecom are both building 5G base stations, but they have their own operating systems.
Due to the increasing complexity of the mobile Internet, traditional users can not provide more self-organizing capabilities, and can only rely on manufacturers for maintenance, in this way, due to its huge network maintenance tasks, it will inevitably greatly increase the probability of failure, and the frequent network failures of the three major operators are inevitable.
China, the world's most populous country, faces a huge challenge for its communications system: in high-density urban areas, telecom companies have to build 5 G base stations within a 500-kilometer radius, while setting up micro base stations on high-rise buildings, which makes network maintenance difficult.
China has 1.6 billion mobile**, but China Mobile accounts for 60%, which makes China Mobile's operation and maintenance more difficult, and the high density of users makes China Mobile's network density very high, especially during peak periods, which puts a lot of burden on China Mobile.
With the advent of the 4G and 5G era, among China's three major operators, China Mobile's optical cable transmission network is the most vulnerable, which is very unfavorable for China Mobile, 4G has been commercialized for nearly 10 years, and when purchasing optical cables every year, China Mobile occupies nearly 50% of domestic optical cables, but its optical cable transmission network is far from being as good as China Telecom and China Unicom.
China Telecom is a latecomer operator, acquired China Unicom CDMA in 2008, and since then has gone through three rounds of 3G, 4G and 5G technology updates, but each update interval is relatively short, and China Unicom jointly built a 5G network, but also increased its own operation and maintenance capabilities. Tough.
It can be said that with the rapid development of mobile phones, its technical difficulty is getting bigger and bigger, and now the reliability of mobile phones is getting worse and worse, whether it is foreign or foreign, it is so, ridiculing the network quality in Europe and the United States, this time China Telecom's network speed may make those who care about network problems feel better.
