NarrowBand-Internet Yezvinhu (NB-IoT) inyowani inokurumidza kukura isina waya tekinoroji 3GPP cellular tekinoroji yakaunzwa muRelease 13 inogadzirisa zvinodiwa neLPWAN (Low Power Wide Area Network) zveIoT.Yakaiswa mumhando ye5G tekinoroji, yakamisikidzwa ne3GPP muna 2016. Inyanzvi-yakavakirwa pasi pesimba rakakura nzvimbo (LPWA) tekinoroji yakagadziridzwa kugonesa huwandu hwakasiyana hwezvishandiso zveIoT zvitsva nemasevhisi.NB-IoT inonatsiridza zvakanyanya mashandisirwo emagetsi ezvishandiso zvemushandisi, simba rehurongwa uye spectrum kunyatsoita, kunyanya mukuvhara kwakadzika.Hupenyu hwebhatiri hweanopfuura makore gumi hunogona kutsigirwa kune dzakasiyana siyana dzekushandisa kesi.
Nyowani yemuviri masaini masiginecha uye machaneti akagadzirirwa kusangana nezvinodiwa zvekuwedzera kufukidzwa - kumaruwa uye kwakadzika mukati - uye Ultra-yakaderera mudziyo kuoma.Mari yekutanga yeNB-IoT module inotarisirwa kuenzaniswa neGSM/GPRS.Iyo tekinoroji yepasi iri zvakareruka pane yanhasi GSM/GPRS uye mutengo wayo unotarisirwa kudzikira nekukurumidza sezvo kudiwa kunowedzera.
Inotsigirwa nemidziyo yese mikuru yenhare, chipset uye vagadziri vemodule, NB-IoT inogona kuvapo pamwe ne2G, 3G, uye 4G nharembozha.Izvo zvakare zvinobatsira kubva kune ese akachengeteka uye akavanzika maficha enharembozha, serutsigiro rwekuvanzika kwemushandisi, kuvimbiswa kwesangano, kuvanzika, kutendeseka kwedata, uye kuzivikanwa kwemidziyo yenhare.Yekutanga NB-IoT kushambadzira kwekutengesa kwapera uye kuburitswa kwepasi rose kunotarisirwa 2017/18.
Ndeupi huwandu hweNB-IoT?
NB-IoT inogonesa kutumirwa kwemidziyo yakaderera yakaoma munhamba huru (inoda kusvika 50 000 yekubatanidza pasero).Kureba kwesero kunogona kubva ku40km kusvika ku100km.Izvi zvinobvumira maindasitiri akaita sezvishandiso, manejimendi easset, logistics uye manejimendi ezvikepe kuti abatanidze masensa, trackers uye metering zvishandiso nemutengo wakaderera uchivhara nzvimbo yakakura.
NB-IoT inopa kuvharika kwakadzama (164dB) kupfuura matekinoroji mazhinji eLPWAN uye 20dB kupfuura yakajairika GSM/GPRS.
Ndeapi matambudziko anogadziriswa neNB-IoT?
Iyi tekinoroji yakagadzirirwa kusangana nezvinodiwa zvekuwedzera kufukidzwa nekushandiswa kwemagetsi mashoma.Midziyo inogona kupihwa simba kwenguva yakareba pabhatiri rimwe chete.NB-IoT inogona kuendeswa uchishandisa iripo uye yakavimbika nharembozha.
NB-IoT zvakare ine zvimiro zvekuchengetedza zviripo muLTE cellular network, sekudzivirira kwechiratidzo, chengetedzo yechokwadi uye encryption yedata.Inoshandiswa pamwe chete neAPN inotungamirwa, inoita kuti manejimendi yekubatanidza iite nyore uye yakachengeteka.
