NarrowBand-Internet of Things (NB-IoT) ndi mulingo watsopano waukadaulo wopanda zingwe womwe ukukula mwachangu wa 3GPP woyambitsidwa mu Release 13 womwe umakwaniritsa zofunikira za LPWAN (Low Power Wide Area Network) za IoT.Yasankhidwa ngati teknoloji ya 5G, yovomerezeka ndi 3GPP mu 2016. Ndi teknoloji yochokera ku low power wide area (LPWA) yopangidwa kuti ithandize zipangizo ndi ntchito zatsopano za IoT.NB-IoT imathandizira kwambiri kugwiritsa ntchito mphamvu kwa zida za ogwiritsa ntchito, mphamvu zamakina ndi magwiridwe antchito, makamaka pakuwunikira kwambiri.Moyo wa batri wopitilira zaka 10 utha kuthandizidwa pazinthu zingapo zogwiritsa ntchito.
Zizindikiro ndi ma tchanelo atsopano amapangidwa kuti akwaniritse zofunikira kuti athe kufalikira - kumidzi ndi mkati mwanyumba - komanso zovuta zotsika kwambiri.Mtengo woyambirira wa ma module a NB-IoT ukuyembekezeka kufanana ndi GSM/GPRS.Ukadaulo wapansi pano ndi wosavuta kuposa wa GSM/GPRS wamasiku ano ndipo mtengo wake ukuyembekezeka kutsika mwachangu pomwe kufunikira kukuwonjezeka.
Mothandizidwa ndi zida zonse zazikulu zam'manja, opanga ma chipset ndi ma module, NB-IoT imatha kukhalapo ndi 2G, 3G, ndi 4G ma network.Imapindulanso ndi chitetezo chonse komanso zinsinsi zamamanetiweki am'manja, monga kuthandizira chinsinsi cha ogwiritsa ntchito, kutsimikizika kwa kampani, chinsinsi, kukhulupirika kwa data, ndi chidziwitso cha zida zam'manja.Kukhazikitsa koyamba kwa malonda a NB-IoT kwatha ndipo kukuyembekezeka kutulutsidwa padziko lonse lapansi mu 2017/18.
Kodi mtundu wa NB-IoT ndi wotani?
NB-IoT imathandizira kuyika zida zovutirapo pang'onopang'ono (pafupifupi zolumikizira 50 000 pa cell).Kutalika kwa selo kumatha kuchoka pa 40km mpaka 100km.Izi zimathandizanso mafakitale, magwiridwe antchito a katundu, zowongolera ndi zowongolera zolumikizira zolumikizira zitsulo zotsika mtengo mtengo wotsika mtengo.
NB-IoT imapereka chidziwitso chozama (164dB) kuposa matekinoloje ambiri a LPWAN ndi 20dB kuposa GSM/GPRS wamba.
Kodi NB-IoT imathetsa mavuto ati?
Tekinoloje iyi idapangidwa kuti ikwaniritse kufunikira kwa kufalikira kwakutali ndi kugwiritsa ntchito mphamvu zochepa.Zipangizo zimatha kuyendetsedwa kwa nthawi yayitali kwambiri pa batri imodzi.NB-IoT ikhoza kutumizidwa pogwiritsa ntchito zida zomwe zilipo komanso zodalirika zama cell.
NB-IoT ilinso ndi zida zachitetezo zomwe zimapezeka mumanetiweki am'manja a LTE, monga chitetezo chazidziwitso, kutsimikizika kotetezedwa ndi kubisa kwa data.Kugwiritsidwa ntchito molumikizana ndi APN yoyendetsedwa, kumapangitsa kasamalidwe ka kulumikizana kwa chipangizo kukhala kosavuta komanso kotetezeka.
