Frequency sharing of the international maritime satellite mobile communication system and the next generation IMT system
Abstract
According to the “Table of Frequency Allocations of People’s Republic of China”and the relevant provisions of the“Radio Regulations”，it is shown that there are frequency overlap between the space to ground（down） link of the fourth-generation international maritime satellite（INMARSAT）mobile communication system and the next generation international mobile telecommunication（IMT）system in China. In order to guarantee the coexistence of the fourth-generation INMARSAT mobile communication system and the next generation of IMT system，the operation prerequisites or protection distances were analyzed. Based on the theoretical analysis，the simulation and survey of production level of equipment company，some suggestions on how to make the above two systems coexist were presented.
