Performance of a Long Troposcatter Link in the Southeast Asia Equatorial Region

This paper presents the results of a propagation survey and the actual performance of a subsequently installed troposcatter system between East and West Malaysia, a distance of 739 km (463 mi), mainly over water. The survey was carried out at 1840 MHz and the installed system uses the 900-MHz band. The path attenuation results are compared with predictions based on the International Radio Consultative Committee (CCIR) method. The noise performances of the installed system with a capacity of 48 voice channels are compared against CCIR objectives for the hypothetical reference circuit.
