Recently, the Ministry of Industry and Information Technology of China issued a notice to adjust the use plan of the 700MHz spectrum and officially use it for 5G communications.
700MHz has been regarded as a "golden frequency band". Although the capacity is not large, as a low-frequency band, it has the advantages of low propagation loss, wide-coverage, strong penetration, and low networking cost.
This frequency band has been allocated to China Radio and Television, and has been incorporated into the 5G international standard, and is also the world's first low-band large-bandwidth 5G standard.
This series of facts has released the signal that the Ministry of Industry and Information Technology encourages the four major operators to share spectrum. The shared spectrum means that operators '5G construction can use different network roaming methods to increase network speed and reduce network construction costs.
Inter-network roaming, to put it simply, is the SIM card contracted by the communications operator contracted by the user and can also use the network of another communications operator. This approach can help operators reduce redundant construction and form complementary network resources.
Telecom analyst and communications industry writer Shang Xiaopu said that in terms of the characteristics of China's communications market, in low-traffic areas with a large population and a small number of people, if operators roam between different networks, the speed of network construction can be improved and the cost of network construction can be reduced.
From the perspective of technology iteration, it is also a general trend for operators to share network technology.
