NarrowBand-Interineti yibintu (NB-IoT) nuburyo bushya bwihuta bwihuta bwikoranabuhanga rya 3GPP ryikoranabuhanga rya selile ryatangijwe muri Release 13 ryita kuri LPWAN (Umuyoboro muke muto wa Network) ibisabwa na IoT. Yashyizwe mu rwego rwa tekinoroji ya 5G, igenderwaho na 3GPP mu 2016. Ni igipimo gishingiye ku gipimo gishingiye ku mbaraga nkeya (LPWA) ikoranabuhanga ryakozwe kugira ngo ritange ibikoresho byinshi na serivisi bishya bya IoT. NB-IoT itezimbere cyane gukoresha ingufu zikoreshwa ryibikoresho byabakoresha, ubushobozi bwa sisitemu hamwe nuburyo bugaragara, cyane cyane mubwishingizi bwimbitse. Ubuzima bwa bateri bwimyaka irenga 10 burashobora gushyigikirwa muburyo butandukanye bwo gukoresha.
Ibimenyetso bishya byumubiri hamwe numuyoboro byateguwe kugirango byuzuze ibisabwa kugirango habeho kwaguka - icyaro ndetse n’imbere mu nzu - hamwe n’ibikoresho bito cyane. Igiciro cyambere cya moderi ya NB-IoT giteganijwe kugereranywa na GSM / GPRS. Ikoranabuhanga ryibanze ariko ryoroshye cyane kurenza GSM / GPRS yumunsi kandi biteganijwe ko igiciro cyayo kizagabanuka vuba uko ibyifuzo byiyongera.
Gushyigikirwa nibikoresho byose bigendanwa bigendanwa, chipset hamwe nabakora module, NB-IoT irashobora kubana na 2G, 3G, na 4G imiyoboro igendanwa. Iyungukiramo kandi ibintu byose biranga umutekano n’ibanga biranga imiyoboro igendanwa, nko gushyigikira ibanga ry'umukoresha, kwemeza ibigo, ibanga, ubunyangamugayo, no kumenyekanisha ibikoresho bigendanwa. Imurikagurisha ryambere rya NB-IoT ryarangiye kandi biteganijwe ko isi yose izashyirwa ahagaragara muri 2017/18.
Ni ubuhe bwoko bwa NB-IoT?
NB-IoT ituma hashyirwaho ibikoresho bito bigoye cyane (umubare uhuza 50 000 kuri selile). Urwego rw'akagari rushobora kuva kuri 40km kugeza 100km. Ibi bituma inganda nkibikorwa byingenzi, imicungire yumutungo, ibikoresho hamwe nubuyobozi bwamato guhuza ibyuma bifata ibyuma bifata ibyuma bikurikirana, bikurikirana hamwe nibikoresho bipima ku giciro gito mugihe gikubiyemo ahantu hanini.
NB-IoT itanga amakuru yimbitse (164dB) kurusha tekinoroji ya LPWAN na 20dB kuruta GSM / GPRS isanzwe.
Ni ibihe bibazo NB-IoT ikemura?
Iri koranabuhanga ryashizweho kugirango rihuze icyifuzo cyo kwaguka hifashishijwe ingufu nke. Ibikoresho birashobora gukoreshwa mugihe kirekire cyane kuri bateri imwe. NB-IoT irashobora koherezwa hakoreshejwe ibikorwa remezo bya selile kandi byizewe.
NB-IoT ifite kandi ibimenyetso byumutekano biboneka mumiyoboro ya selile ya LTE, nko kurinda ibimenyetso, kwemeza umutekano hamwe no kubika amakuru. Ikoreshwa ifatanije na APN icungwa, ituma imiyoborere ihuza ibikoresho byoroshye kandi bifite umutekano.
