A Study on the Compatibility Analysis of Radio Altimeter for Efficient Frequency Utilization

This paper outlines a compatibility analysis method designed to assess the coexistence of 5G mobile service and the current radio altimeter within the 4.2 - 4.4 GHz frequency band. Additionally, interference analysis was conducted to investigate the potential compatibility between the radio altimeter and the 5G mobile communication service, specifically examining scenarios where the 5G system operates indoors within the 4.0 - 4.2 GHz bands, utilizing our proposed methodology.
