Statistical study to determine the sample size to define a propagation model adjusted to the equatorial jungle environment: A proposal to optimize telecommunications resource I

Abstract:

This work shows a methodology to determine the sample size required to define a propagation model adjusted to a specific and uncharacterized jungle region, based on the Longley Rice (L-R) propagation model. The analysis is performed in the HF frequency band and using high performance military tactical communication equipment. Initially, a simulation of the telecommunications system to be implemented were developed using the Radio Mobile platform. Subsequently, through the field measurements done insitu, we estimated the interval of confidence to get an accurate model and the data size to get such interval. The research includes a set of meteorological measurements to validate and characterize the environment under which the optimization is going to be applied. The results obtained yields a set of protocols for determining propagation models to be used on voice, video and data transmission in hostile and uncharacterized areas.
