Internet stvari ili IoT sustav je međusobno povezanih računalnih uređaja, mehaničkih i digitalnih strojeva, objekata, životinja ili ljudi koji imaju jedinstvene identifikatore (UID) i mogućnost prijenosa podataka preko mreže bez potrebe za komunikacijom od čovjeka do interakcija čovjeka ili čovjeka s računalom. Nagli razvoj IoT-a i problemi s pokrivenosti i potrošnjom energije koji postojeći protokoli nisu zadovoljavali doveli su do pojave mreža velikog dometa i male potrošnje. Vodeće LPWAN mreže su LoRaWAN, Sigfox i NB-IoT bežične senzorske mreže. Oni zadovoljavaju potrebe cijene, učinkovitosti, dometa, kvalitete... Prenose male količine podataka na velike udaljenosti uz nisku potrošnju energije. U radu su opisane te tri bežične senzorske mreže i navede su njihove glavne karakteristike te nakraju njihova međusobna usporedba po cijeni, pokrivenosti, dometu, sigurnosti... i doneseni su zaključci koja mreža je najbolja i najučinkovitija za pojedine zahtjeve IoT aplikacija. The Internet of Things or IoT is a system of interconnected computer devices, mechanical and digital machines, objects, animals or people that have unique identifiers (UID) and the ability to transfer data over a network without the need for human-to-human communication or human-computer interactions. The rapid development of IoT and problems with coverage and energy consumption that existing protocols did not satisfy led to the emergence of LPWAN, that is, low-power wide area networks. The leading LPWAN networks are LoRaWAN, Sigfox and NB-IoT wireless sensor networks. They meet the needs of price, efficiency, range, quality... They transmit small amounts of data over long distances with small energy consumption. The paper describes these three wireless sensor networks and lists their main characteristics, and finally their mutual comparison in terms of price, coverage, range, security... and conclusions are drawn as to which network is the best and most efficient for certain requirements of IoT applications.
