NarrowBand-Internet of Things (NB-IoT) sabuwar fasaha ce mai saurin girma mara waya ta 3GPP ma'aunin fasahar salon salula wanda aka gabatar a cikin Sakin 13 wanda ke magance buƙatun LPWAN (Low Power Wide Area Network) na IoT. An rarraba shi azaman fasahar 5G, wanda aka daidaita ta 3GPP a cikin 2016. Fasaha ce mai ƙarancin ƙarfi mai ƙarfi (LPWA) wacce aka haɓaka don ba da damar sabbin na'urori da ayyuka iri-iri na IoT. NB-IoT yana haɓaka ƙarfin amfani da na'urorin masu amfani, ƙarfin tsarin da ingantaccen bakan, musamman a cikin zurfin ɗaukar hoto. Rayuwar baturi na fiye da shekaru 10 ana iya tallafawa don yawancin lokuta na amfani.
An ƙirƙira sabbin sigina na Layer na jiki da tashoshi don biyan buƙatun buƙatu na tsawaita ɗaukar hoto - ƙauye da zurfin ciki - da ƙaƙƙarfan na'ura mai ƙarancin ƙarfi. Ana tsammanin farashin farko na kayan aikin NB-IoT zai yi daidai da GSM/GPRS. Fasahar da ke ƙasa ta fi sauƙi fiye da GSM/GPRS ta yau kuma ana sa ran farashinta zai ragu da sauri yayin da buƙata ta ƙaru.
Goyan bayan duk manyan kayan aikin hannu, kwakwalwan kwamfuta da masana'anta, NB-IoT na iya kasancewa tare da cibiyoyin sadarwar wayar hannu na 2G, 3G, da 4G. Hakanan yana fa'ida daga duk fasalulluka na tsaro da keɓaɓɓun hanyoyin sadarwar wayar hannu, kamar goyan bayan sirrin sirrin mai amfani, tantance mahallin, sirri, amincin bayanai, da tantance kayan aikin wayar hannu. An kammala ƙaddamar da kasuwancin NB-IoT na farko kuma ana sa ran fitar da duniya don 2017/18.
Menene kewayon NB-IoT?
NB-IoT yana ba da damar tura ƙananan na'urori masu rikitarwa a cikin lambobi masu yawa (kimanin haɗin 50 000 a kowace tantanin halitta). Iyakar tantanin halitta na iya tafiya daga 40km zuwa 100km. Wannan yana ba da damar masana'antu kamar kayan aiki, sarrafa kadara, dabaru da sarrafa jiragen ruwa don haɗa na'urori masu auna firikwensin, trackers da na'urori masu aunawa a farashi mai sauƙi yayin rufe yanki mai faɗi.
NB-IoT yana ba da ɗaukar hoto mai zurfi (164dB) fiye da yawancin fasahar LPWAN da 20dB fiye da GSM/GPRS na al'ada.
Wadanne matsaloli NB-IoT ke magance?
An tsara wannan fasaha don saduwa da buƙatun ɗaukar hoto tare da ƙarancin amfani. Ana iya kunna na'urori na dogon lokaci akan baturi ɗaya. Ana iya tura NB-IoT ta amfani da kayan aikin salula na zamani kuma abin dogaro.
NB-IoT kuma yana da fasalulluka na tsaro da ke cikin cibiyoyin sadarwar salula na LTE, kamar kariyar sigina, ingantaccen tabbaci da ɓoye bayanan. An yi amfani da shi tare da APN mai sarrafawa, yana sa sarrafa haɗin na'ura mai sauƙi da aminci.
