Especially from the approval of the Ministry of Industry and Information Technology, China Telecom benefited the most from using the 800 MHZ frequency band. The scope of use this time is the whole country 14 provinces and cities. Low-frequency signals have low cost and fast Internet access, which can better promote the construction of 4g and 5g. The realization of 800HZ low frequency band can improve some problems, for example, the coverage of high frequency signal we use is not enough, because the range of high frequency signal is generally narrow.
For example, there is a WiFi installed at home, but there is basically no signal when you turn a corner. The 800MHZ frequency band promoted by the Ministry of Industry and Information Technology is a national network, which can overcome this difficulty. But the real implementation still needs to build more base stations, which is also a big problem for operators. Building more base stations also requires more wireless equipment and transmission resources, which is a huge investment, but now with the backing of the Ministry of Industry and Information Technology, the problem is not big.
With the low frequency band of 800MHZ being used in the network construction of 4G and 5G, it means that our future network will be more developed and the network quality will be better improved. However, China Telecom has also raised an important difficulty on this issue, that is, the business volume of 800MHZ frequency is relatively large in rural areas, but it is also extremely difficult to implement, because most people in rural areas always have a natural rejection of base stations, which requires our relevant departments to carry out scientific publicity and popularization so that residents can accept it.
