Summary:
|
The tropospheric duct phenomenon can cause extremely long-distance propagation of downlink signals, leading to electromagnetic compatibility issues with 5G TDD base stations and resulting in severe degradation of network performance.
This new research is to study the methods to EMC issues resulting from an electromagnetic phenomenon caused by tropospheric duct effects. The phenomenon falls under the category of EMC issues, which are not wanted, under specific physical conditions, it occurs under certain weather conditions, allowing electromagnetic waves to propagate over long distances within a ducting layer. It is a physical phenomenon, just like mirages caused by atmospheric optical effects.
