Abstract

Eksponencijalnim porastom prometa na internetu posljednjih nekoliko godina pojavila se potreba za rješenjima koja će poslovnim i privatnim korisnicima osigurati brzinu pristupa internetu od nekoliko desetaka Mbps ili više. Obzirom na stanju DTK infrastrukture, takvo rješenje za značajan dio korisnika može biti samo bežični sustav komunikacije, stoga je cilj ovog rada utvrditi pouzdanost i kvalitetu usluga takvih sustava u zahtjevnijim vremenskim uvjetima. Mjerenja po visokim i nešto nižim temperaturama te u suhim uvjetima, slaboj i jakoj kiši pokazala su da ne postoji korelacija između vremenskih uvjeta i kvalitete usluge putem takvog linka na frekvenciji od 5 oko GHz. Frekvencije preko 10 GHz vjerojatno bi pokazale značajno drugačije rezultate.

Abstract (english)

Exponential growth of traffic on internet in last few years has resulted with need for solutions that would allow business and private users access to internet with bandwith greater that few tens of Mbps. With state of distributive telecommunication infrastructure in mind, for a great number of users only option is a wireless communication system, so the purpose of this research is to determine the reliability and quality of service of those systems in challenging weather conditions. Measurements in high and lower temperatures, dry and rainy conditions have shown that there is little or no correlation between weather and quality of service of those links on frequency aroud 5 GHz. Frequencies above 10 GHz would have probably shown much different results.
