The system is based on a measurement station that has the shape of a floating buoy which is supposed to be at anchor on the reservoir. Wireless data transmission problems that were encountered during the development of the buoy, modeling a radio link, and measurements of actual signal strength on the reservoir are discussed. A mathematical approach to procedures of early situation assessment was conducted, and specialized procedures were designed for measurement stations of the system. It is also discussed how such computations can improve a qualitative assessment of system performance in terms of real-time messaging}, type={Artykuły / Articles}, title={Some Practical Problems of Communications Reliability in Enviromental Monitoring Systems}, URL={http://ochroma.man.poznan.pl/Content/90139/PDF/Journal10178-VolumeXX%20Issue3_02.pdf}, doi={10.2478/mms-2013-0029}, keywords={Monitoring systems, GSM communication, floating buoy, real-time messaging}, }
