Abstract

U radu su detaljno opisane karakteristike NB-IoT radijske tehnologije kao predstavnika LPWAN radijskih mreža. Provedenim mjerenjima analizirana je dostupnost, propagacija i kvaliteta NB-IoT signala u zatvorenim prostorima u usporedbi s drugim radijskim tehnologijama s naglaskom na LTE. Također je napravljeno mjerenje na otvorenom terenu u ruralnom području na lokacijama s graničnom razinom signala. Ovaj rad utvrdio je stvarne uvjete ruba ćelije za NB-IoT tehnologiju na terenu te definirao... More granice u kojima usluga još ima zadovoljavajuću kvalitetu. Less

Abstract (english)

This paper describes characteristics of NB-loT radio technology as a representative of LPWAN radio networks in detail. By using own measurement, penetration, propagation and quality of NB-loT signals in closed areas have been analyzed in comparison with other radio technologies with emphasis on LTE. Moreover, measurement in the open field in rural area on locations with threshold signal strength has been carried out. The aim of this paper was to determine real conditions of the cell-edge... More for NB-loT technology in the field as well as to find limit values in which the service is still of satisfactory quality.
