According to CNET reports, AT&T, the largest operator in the United States, is already preparing for the world‘s first mobile 5G network launched at the end of the year. The current work is to launch more high-frequency 5G network testing to ensure that users can finally experience stability. 5G network speed.
According to the latest progress given by AT&T, it will start intensive testing in the 39GHz spectrum, which will prepare for future coverage of the area (and get more high-speed and low-latency data of 5G NR), and they also plan to A fixed 3GPP-compatible unit is added to Atlanta and Hawaii to ensure long-term testing, stability and continuity.
AT&T’s previous announcement stated that by the end of 2018 (before December 31), it will be the first to commercialize 5G networks in 12 US cities. In 2019, this range will be extended to 19 cities, and in 2020, the United States must have at least 200 million users experience the 5G network.
According to the instructions given by the operator AT&T, the 5G mobile network they are building is up to 125MB/s, and the delay can be controlled within 1 millisecond. However, due to the improvement of the previous infrastructure, the network speed It will be around 50MB/s for the time being, and will be upgraded to the highest 125MB/s.
For the 5G mobile network tariff, this may be the user’s biggest concern, because there is a possibility that everyone can’t afford it, but the high cost of commercial pre-up is inevitable. AT&T said that it will work hard for users. Bring a relatively cheap 5G tariff.
It is reported that AT&T’s 5G mobile network service launched at the end of this year will be launched in the form of a contract machine, which may be better to charge the control fee. As for the specific charging situation, if their member‘s monthly fee is higher than 50 US dollars. It is equivalent to about RMB 350, but it is generally believed that the final price may be higher than this, because the cost of building a 5G network by US carriers is very high, especially the terminal providers such as Huawei (5G base station equipment is very cost-effective). ).
Compared to the 5G mobile network, on October 1 this year, Verizon has announced the launch of the world’s first 5G broadband in the United States. The previous period was only concentrated in Los Angeles, Houston, Annapolis, Indonesia, and parts of Sacramento. It is 70 dollars, about 480 yuan.
What is the current speed of China‘s 5G network?
According to the plan given by the Ministry of Industry and Information Technology, China began trial commercialization of 5G networks in some cities in 2019, and officially launched 5G network commercialization in China in 2020. At present, China Mobile, China Unicom and China Telecom are building 5G networks, of which the latter two The progress is the fastest. For example, China Unicom has promoted 5G network construction and trial commercial conditions in 16 cities across the country. China Telecom has to send more than 1,000 models to support 5G network terminals by March 2019.
The last thing to note is that the current 5G network has not been completely built, let alone commercial, so all mobile phones on the market do not support this network. To experience this network, you must upgrade your mobile phone (mobile phone card). You can upgrade to the corresponding network service without having to renew it. Of course, the operator will also prepare a new 5G network SIM card. In June 2019, there will be a large number of mobile phones supporting 5G network. It includes Huawei and the use of Qualcomm solutions.
