With the development of 4G networks, although the network speed has become faster, the traffic is always insufficient, and the traffic of several hundred megabytes is used for half a month. Mobile, China Unicom and Telecom have found business opportunities and launched a number of package activities on traffic. It costs tens or even hundreds of yuan per month on traffic costs. Now that I am away from home, there is really nothing to do, that is, there can be no WiFi.
But nowadays, WiFi really has a sense of crisis, and the biggest threat to it is 5G.
According to industry estimates, 5G will be commercially available worldwide in 2020. What is the concept of 5G? As the fifth-generation mobile communication network, 5G network has the highest theoretical transmission speed of tens of GB per second, which is hundreds of times faster than the transmission speed of 4G network. The entire ultra-high quality movie can be downloaded within 1 second. .
???? Now what products are laid out 5G network
In 2014, Samsung announced that it has pioneered the development of the first mobile transmission network based on 5G core technology, and said that it will conduct commercial promotion of 5G network by 2020.
In 2016, Nokia and telecom media company Bell once again completed testing of 5G signals in Canada. In the test, Nokia's spectrum in the 73GHz range, the data transmission speed is also six times that of the existing 4G network.
Why do you say that the emergence of 5G network WiFi will exit the stage of history?
In addition to being fast, the 5G network is more stable. 5G network is fast, isn't it more traffic? For this problem, the current major mobile operators in the United States provide unlimited data traffic services, which means that people do not need to connect to WiFi to avoid high traffic charges.
The emergence of this package has directly affected the frequency of use of home broadband. According to a survey released by the US authoritative survey agency, about one-third of people no longer use home broadband connections because their mobile phones have unlimited Data Package.
In addition to the United States, China's three major operators have also launched unlimited traffic packages. In fact, as early as last year, China's three major operators have begun to lay out. In September last year, China Unicom launched the province's unlimited traffic card in Jiangsu. The card can achieve unlimited traffic in the province, 1G traffic nationwide, and free delivery of 1800 minutes of intra-provincial calls. No roaming or answering is available nationwide. The other two operators subsequently launched their own data packages.
Unlimited data packages will appear where WiFi will go
The premise that WiFi will gradually withdraw from the market is that there is a wireless unlimited data package and the price can be accepted by users. However, the decline in WiFi influence may be slow and irregular. Although the unlimited traffic package makes WiFi available to mobile phones, many home devices, such as PCs or Amazon's Echo, still need to connect to the Internet via WiFi. And WiFi can also be used as a supplement to cover office buildings and family homes with poor cell phone signals. Linked to the Internet of Things, the biggest feature of traffic demand: mobile, cost controllable. WIFI Internet access has a certain scope limitation. Due to carrier cost control, WIFI either becomes a traffic sub-interface for 5g access or replaces a new wireless connection.
?? WiFi will gradually withdraw from the market may be a big prospect, but for now this goal is a bit far. After all, domestic operators' traffic costs are very expensive. For example, China Mobile insists that 5 yuan and 10M will not waver, even if the future 5G arrives, but the traffic cost is still the operator's fragrance.
