Recently, the national development and Reform Commission and other relevant departments have approved the pilot construction of 5g network by China Unicom, telecom and China Mobile in some cities, such as Beijing. Is there Chongqing in 5g pilot city? The three major operators have finalized 5g pilot cities, and each city will build more than 100 5g base stations.
Many netizens will say that the reason why the 5g pilot cities of the three major operators do not have Chongqing is because there are too many mountains. Is too much mountain also an impact???
At present, Huairou experimental network, which has been established by the state, is jointly developed by Datang communications, Huawei and keysight. All equipment manufacturers have participated in the experiment. The terminal is the size of a refrigerator. It is obviously just a face project, and the experimental significance is not obvious.
Therefore, the real answer is: too many mountains, the channel does not follow the universal propagation model, which is not conducive to 5g initial scale test. Chengdu and Guiyang are also located at the root of the mountain, but they are basically evenly distributed in the urban areas (not excluding the slope), and only the urban streets in Chongqing have a drop of 50 meters.
1. Which cities to choose is decided by operators, not 'countries', at least on the surface;
2. Testing 5g is not only a field test, but also a business test;
3. The main basis for choosing a city is the original infrastructure (upgrade base station, macro station), talent reserve (communication, radio frequency, network optimization, protocol, etc.) of operators in the corresponding city, and the support of local government.
