Ikoranabuhanga rigufi-interineti (NB-IOT) ni Ikoranabuhanga rishya ryiyongera 3GPP Ikoranabuhanga rya selile ryatangijwe mu kurekura 13 rikemura ibibazo bya LPWAn (Imbaraga zo hasi ( Byashyizwe mubikorwa nkikoranabuhanga rya 5G, risanzwe na 3GPP muri 2016. Nibisanzwe Ikoranabuhanga rishingiye kugari (LPWA) ryateguwe kugirango rishobore gukora ibice byinshi bya II). NB-IOT itezimbere cyane ingufu zikoresha ibikoresho byabakoresha, ubushobozi bwa sisitemu na spectrum imikorere, cyane cyane mubuvuzi bwimbitse. Ubuzima bwa bateri bwimyaka irenga 10 burashobora gushyigikirwa muburyo butandukanye bwo gukoresha.
Ibimenyetso bishya byumubiri hamwe nimiyoboro bigamije kuzuza ibisabwa bisaba ubwishingizi bwongerewe - icyaro no mu nzu yimbitse - kandi ultra-ibikoresho byoroheje. Igiciro cyambere cya NB-Iot Modules iteganijwe kugereranywa na GSM / GPRS. Ikoranabuhanga ryibanze ni ibintu byoroshye kuruta GSM / GPRS hamwe nigiciro cyacyo gicibwa vuba mugihe cyongera ibisabwa.
Gushyigikirwa nibikoresho byose bigendanwa, chipset na module Abakora, NB-iot barashobora kubana na 2g, 3g, na 4g imiyoboro igendanwa. Inyungu kandi mu mikorere yose n'ibiranga imiyoboro igendanwa, nko gushyigikira ibanga ry'umukoresha, kwemeza, ibanga, ubunyangamugayo, hamwe no kumenya ibikoresho bigendanwa. Ibikorwa byambere NB-Uot-Iot byarangiye kandi byicaroka ku isi biteganijwe ko muri 2017/18.
Ni ubuhe buryo bwa NB-iot?
NB-IOT ifasha kohereza ibikoresho bike bigoye mumibare nini (hafi 50 000 guhuza kuri buri selile). Intera ya selile irashobora kuva kuri 40km kugeza 100km. Ibi bituma inganda zimeze neza, imitunganyirize, ibikoresho hamwe nubuyobozi bwamato hamwe no guhuza sensor, abakurikirana nibikoresho byo guswera ku giciro gito mugihe gitwikiriye ahantu hanini.
NB-IOT itanga ubwishingizi bwimbitse (164Db) kuruta tekinoroji myinshi ya LPWAN na 20DB ibirenze GSM / GPRS isanzwe.
Ni ibihe bibazo nb-uot ikemura?
Iri koranabuhanga ryateguwe kugirango ryumvikane icyifuzo cyongerewe no gukoresha imbaraga nke. Ibikoresho birashobora gukoreshwa mugihe kirekire cyane kuri bateri imwe. NB-IOT irashobora koherezwa ukoresheje ibikorwa remezo bihari kandi byizewe.
NB-IOT nayo ifite imiterere yumutekano iboneka mumiyoboro ya lte, nko kurinda ibimenyetso, kwemeza umutekano hamwe namakuru ahili. Ikoreshwa ifatanije na apn iyobowe, ituma ibikoresho bihuza ibikoresho byoroshye kandi bifite umutekano.
