Cross-Border Coordination between International Mobile Telecommunications System and Aeronautical Telemetry System in the 1429–1518 MHz Frequency Band

this paper presents the co-channel compatibility analysis between Aeronautical Mobile Telemetry system (ATS) and International Mobile Telecommunications system (IMT) in the frequency band 1427 MHz-1518 MHz. IMT are developing at staggering rates and mobile operators always search for new possible frequency bands to expand their mobile and fixed communication networks (MFCN) and 1427 MHz-1518 MHz frequency band is attractive due to the qualified radio propagation conditions. However, this band is already operated by other technologies, such as aeronautical networks, radio relay, broadcasting networks, in the neighbouring countries. Co-channel and adjacent channel electromagnetic compatibility have to be evaluated. Electromagnetic compatibility between ATS and IMT is one of the most sensitive issues regarding the decision to identify this band to IMT. This paper was conducted to compare two protection criteria methods, i.e. I/N and C/(I + N).
