- Abstract
In order to analyze the feasibility of introducing fixed wireless access system in 40. 5 ~ 2. 3 GHz and 48. 4 ~ 50. 2 GHz, the electromagnetic compatibility between the fixed wireless access system and other systems of the principal services is studied according to the Radio Frequency Allocation Table. With computer static modeling method, that the interference power density of the fixed wireless access system to the systems of fixed service, fixed-satellite service, broadcasting service and radio astronomy varies with distance is discussed, and the separation distances in different interference scenarios are obtained according to interference protection criteria for related services. The result shows that the fixed wireless access system may not cause harmful interference to existing principal service systems under certain separation distance conditions and these bands can be used for fixed wireless access system beyond the separation distance. The conclusion can be used to support the re-allocation of the bands by the national radio spectrum management department.
