In order to solve the problem of wireless signal coverage in areas with poor natural conditions or sparse population,or to ensure communication in emergency and disaster relief scenarios where the ground network is interrupted caused by natural disasters,and to solve direct connection between public terminals and satellites,NTN networks are paid attention from the industry.NTN networks,represented by satellite direct connection,take into account the characteristics of 5G network,and the biggest contribution is to solve the problem of mass terminal direct connection to the satellite,without the need for special terminals.It focuses on the application scenarios and key technologies of NTN networks,and also discusses the development of NTN networks.
