The HCM4A (Harmonized Calculation Method for Africa) Programmes are programmes developed for the harmonized application of the calculation methods as provided in the Annexes of the HCM4A Agreement.
Each ‘HCM4A Programme’ consists of the source code, including related Dynamic Link Library (DLL), the official surrounding programme (*.EXE), and the programme documentation. Every Administration is free to use the source code. In case of dispute, the official DLL utilised via the official HCM4A surrounding programme will be used as a reference.
The representatives of the administrations listed below are part of the Agreement, under Article 6 of the International Telecommunication Union Radio Regulations (ITU RR), on the coordination of frequencies between 29.7 MHz and 43.5 GHz for the purposes of preventing mutual harmful interference to the Fixed and Land Mobile Services and optimising the use of the frequency spectrum above all on the basis of mutual agreements. This Agreement is referred to as Harmonized Calculation Method for Africa Agreement (HCM4A Agreement) [2022]
