NB - IoT yog ib qho kev siv tshuab uas ua rau muaj ntau yam khoom siv xa cov ntaub ntawv uas tsis muaj cov txheej txheem mobile network. Nws siv cov ntawv tso cai zaus spectrum uas tsis muaj kev cuam tshuam nrog lwm yam khoom siv uas lav tau cov ntaub ntawv hloov pauv ntau dua.

Ntxiv rau qhov no, vim li cas NB hauv IoT?

NarrowBand-Internet ntawm Yam ( NB - IoT ) yog cov qauv siv hluav taws xob qis dav dav (LPWA) thev naus laus zis tsim los ua kom muaj ntau yam tshiab IoT khoom siv thiab kev pabcuam. NB - IoT ho txhim kho lub zog noj ntawm cov neeg siv khoom, lub peev xwm thiab spectrum efficiency, tshwj xeeb tshaj yog nyob rau hauv sib sib zog nqus kev pab them nqi.

Puas yog NB IoT xav tau SIM daim npav? NB - IoT khoom siv xav tau SIM uas tau muab rau ntawm APN tshwj xeeb. Vodacom: NB - IoT cov kev pabcuam tam sim no tuaj yeem qhib rau ntawm ib daim ntawv cog lus SIM daim npav (10 lossis 14 tus lej). Tam sim no tsis muaj nyob rau hauv prepaid.

Tsuas yog li ntawd, NB IoT technology yog dab tsi?

Narrowband IoT . Los ntawm Wikipedia, dawb encyclopedia. Narrowband Internet ntawm Yam ( NB - IoT ) yog ib lub xov tooj cua Low Power Wide Area Network (LPWAN). tshuab tus qauv tsim los ntawm 3GPP los ua kom muaj ntau yam khoom siv ntawm tes thiab kev pabcuam.

Qhov txawv ntawm NB IoT thiab LTE M yog dab tsi?

Hauv ib nutshell, NB - IoT muaj kev sib txuas cov ntaub ntawv bandwidth tsawg ntawm tus nqi qis thiab tam sim no yog Europe tsom, thaum LTE - M yog optimized rau siab dua bandwidth thiab mobile sib txuas, nrog rau lub suab. LTE - M muaj ntau dua throughput nrog qis latency thiab siv roj teeb optimized raws li.
