Yintoni iteknoloji ye-NB-IOI?

I-nerrowband-Internet yezinto (NB-IOI) ngumdlalo weTekhnoloji entsha ye-3GP ye-3GP yeTekhnoloji eyaziwe ekukhupheleni kwe-LPWAn (iNethiwekhi yeNdawo ePhakamileyo). Ihlelwe njengetekhnoloji ye-5G, inomgangatho omiselweyo nge-3GPP ngo-2016. Ingumgangatho ophantsi wecandelo eliphantsi kakhulu (i-LPWA) itekhnoloji yeTekhnoloji ye-LPWA) ukwenzela ukuba uluhlu olubanzi lwezixhobo ze-IOI ezintsha kunye neenkonzo. I-NB-IOI iphucula ubukhulu bokusetyenziswa kwezixhobo zabasebenzisi, amandla okwenza inkqubo kunye nokusebenza kwempumelelo kwe-vism, ngakumbi ekugubungelweni. Ubomi bebhetri yeminyaka engaphezu kwe-10 inokuxhaswa kuluhlu olubanzi lweemeko zokusetyenziswa.

Imiqondiso emitsha yomzimba kunye neendlela zenzelwe ukuhlangabezana nemfuno yokuhlawula imfuneko yokukhutshelwa kwendawo eyandisiweyo-ngaphakathi kunye nokunzulu ngaphakathi kunye nenzulu- kunye ne-Ultra. Iindleko zokuqala zeemodyuli ze-NB-IOI kulindeleke ukuba zithelekise kwi-GSM / GPRS. Itekhnoloji engaphantsi kwengqondo ilula kakhulu kune-GSM / GPRS ye-GSM kunye neendleko zayo kulindeleke ukuba inciphe ngokukhawuleza njengoko imfuno inyuka.

Ixhaswe zizixhobo eziphambili zeselula, abavelisi bemodyuli kunye neemodyuli, i-NB-IOI ingabakho nge-2g, i-3G, kunye ne-4G. Ikwazibonelelo kulo lonke ukhuseleko kunye neempawu zabucala zenethiwekhi yefowuni, ezinjengenkxaso yokuyimfihlo yomsebenzisi, ukungqinisisa, ukungqinelana kwedatha, kunye nokuchongwa kweesoftware. I-NOI yokuqala ye-NB-IOI igqityiwe kwaye ukukhutshwa kwehlabathi kulindeleke kunyaka ka-2017/18.

Luluphi uluhlu lwe-NB-IOI?

I-NB-IOI yenza ukuba ukuthunyelwa kwezixhobo eziphantsi kwempahla eziphantsi kwiinombolo ezinkulu (malunga ne-50 000 uqhagamshelo nganye nganye). Uluhlu lweseli lunokuvela kwi-40km ukuya kwi-100km. Oku kuvumela iishishini njengezixhobo, ulawulo lweeasethi, izixhobo kunye nolawulo lweenqwelo-mafutha ukunxibelelana ngezinzwa, iiprackers kunye nezixhobo zokulinganisa ngexabiso eliphantsi ngelixa igubungela indawo ebanzi.

I-NB-IOI ibonelela ngokudibeneyo

Zeziphi iingxaki olwenza ngayo i-NB-IOI?

Le teknoloji yenzelwe ukuhlangabezana nemfuno yokwandiswa kokusetyenziswa kwamandla asezantsi. Izixhobo zinokuxhonywa ixesha elide kakhulu kwibhetri enye. I-NB-IOI inokukhutshelwa kusetyenziswa izixhobo zeselula nezithembekileyo.

I-NB-IOI ikwanezinto zokhuseleko ezikhoyo kwinethiwekhi ye-lte yeselula, njengokhuseleko lomqondiso, ukuqinisekiswa okukhuselekileyo kunye ne-encryption encryption. Isetyenziswe ngokudibeneyo ne-APN elawulwa, yenza ukuba ulawulo lwezixhobo lulula kwaye lukhuselekile.
