C-대역 기상레이다와 5GHz대역 WLAN장비의 전파간섭 해결 사례연구 = A Case Study on Resolving Interference between C-Band Weather Radar and 5GHz Band WLAN Equipments

다국어 초록 (Multilingual Abstract)

At airports, various types of equipment that utilize electromagnetic waves are operated to ensure the safety of aircraft. According to the aeronautical frequency allocation regulations, frequencies are assigned by purpose, and installations are selected based on operational considerations. However, frequency interference occurs frequently, due to the limited frequency resources and the spatial constraints of the airport environment. In particular, frequency interference between C-band weather radar and 5GHz band WLAN equipment occurs frequently, and ongoing research is being conducted to mitigate this issue. This paper addresses a case of radio frequency interference between C-band weather radar and 5GHz band WLAN equipment operating in close proximity within an airport. By applying frequency optimization and a commercial band-pass filter, successfully eliminated jamming on the weather radar, resolved issue such as communication speed degradation and frequent failure of the low noise amplifier in the WLAN equipment
