Cov Ntaub Ntawv Qhia - Hauv Is Taws Nem (iot) thev naus laus zis

Cat M1 thiab NB - iot tam sim no ob qhov kev xaiv nrov tshaj plaws IOT IOT kev sib txuas. To taub cov ntawv thov thiab lawv qhov sib txawv yog qhov tseem ceeb kom nrhiav cov cuab yeej thev naus laus zis los txhawb ib qho kev thov. Kab lus no qhia meej txog lub ntsiab sib txawv thiab kev siv ntawm NB - iot thiab miv - M1.
Qhov kev nce hauv Is Taws Nem ntawm cov khoom (iot) hauv ob peb xyoos dhau los yog cov ntaub ntawv zoo, thiab cov kws txawj twv kwv yees tias tus naj npawb ntawm IOT cov cuab yeej yuav ncav cuag 75 billion. Txhawm rau txhawb nqa qhov tshwm sim no, project cov thawj tswj hwm thiab cov neeg tsim khoom lag luam uas lawv yuav tsum tau ua tiav cov tswv yim tshiab rau kev ua lag luam.
Txawm hais tias technically hais lus, cov kev txuas tuaj yeem ua tiav txoj haujlwm no, kev ua haujlwm tau zoo, tsim cov txiaj ntsig zoo, tsim cov lag luam zoo, thiab tso cai rau kev tsim kho yam tsis muaj kev txhawj xeeb. Cov. Qhov ob pom ntau dua IOT kev sib txuas hom hnub no yog LTE Cat - M1 thiab NB - iot.
Cov hauv qab no yog qhov sib txawv ntawm LTE Cat M1 thiab NB - IOT, thiab qhov twg yog qhov zoo tshaj rau koj qhov project iot.
LTE - M (LTE Cat - M lossis Miv - M1) yog cov ntaub ntawv tshiab txawb tsim nyog rau kev loj hlob LPWA lossis qes - Cov Khoom Lag Luam - Cheeb Tsam. Nws yog qhov tsim nyog rau cov qes qes - rau - cov ntaub ntawv nruab nrab kis tau dhau mus deb.
MAT - M1 muab cov bandwid nrawm txaus los hloov ntau qhov tam sim no 2G thiab 3G IOT daim ntawv thov. Nws sib txawv ntawm NB - iot hauv ntau txoj kev hwm ntawm tes: M1 Txhawb nqa cov ntawv thov mobile xws li cov cuab tam taug qab zoo xws li tswj hwm. Nws tseem txhawb cov suab ua haujlwm hauv cov ntawv thov IOT, xws li cov khoom siv kho mob thiab lub tsev uas tib neeg muaj peev xwm tham yog qhov tseem ceeb heev.
Tus qauv siv 1.4 MHz bandwidth thiab muaj txaus los ntawm kev hloov kho firrite, software, thiab lwm yam kev hloov kho kev nyab xeeb, suav nrog paub tab phib tawj - Ib yam dab tsi uas NB - iot tsis tuaj yeem ua. Ib qho ntxiv, miv - M1 txhawb nqa puv - Duplex thiab ib nrab - txhais tau tias cov tuam txhab siv hluav taws xob zoo li cas los ntawm kev xaiv ib nrab - Duplex. Nws muaj upload thiab rub tawm kev ceev ntawm 1mbps thiab qis qis ntawm 10 txog 15 milliseconds, ua rau sai dua.
Cov kev siv ntawm miv feem ntau - M1 suav nrog cov khoom siv hnav hnav xws li cov tshuab qoj ib ce thiab cov cuab yeej taug qab thiab cov cuab tam saib xyuas kev noj qab haus huv. Nws tseem dav siv hauv kev siv metering, kev saib xyuas kev nyab xeeb, kev saib xyuas cov tshuab thiab telematics.
NB - iot (Nqis (sparowband online ntawm tej yam lossis nb1) yog lwm cov ntaub ntawv loj tshiab rau kev cog qoob loo rau low - wower wireless appelesss (LPWA). NB - iot muaj uplin ceev ntawm 66kbps thiab rub tawm nrawm ntawm 26kbps nyob rau hauv ib nrab - hom ntawv, uas txhais tau tias cov ntaub ntawv tsuas yog kis tau nyob rau hauv ib qho kev taw qhia ib zaug. Nws tseem muaj kev ncua ntawm 1.6 mus txog 10 vib nas this.
Nws ua haujlwm nyob rau hauv ib tug heev nqaim bandwidth (180 khz) thiab tuaj yeem tso rau hauv cov neeg zov menyuam sib txuas ntawm LTE network, uas yog nyob ntawm cov channel nyob rau hauv kev tsis siv ntawm lub spectrum. Yog li ntawd, nws yog qhov tsim nyog rau cov haujlwm iot nrog ntau cov kev pab, thiab cov muaj ntau yog muaj technologies tam sim no xws li Cat M1, uas yog qhov ua tau zoo. NB - IOT muab kev tiv thaiv zoo dua ntawm cov tsev thiab cov nyom.
NB - IOT Relies on Yooj yim Willforms txuas, thiab nws noj ntau heev me me piv rau LTE miv M1. Yog li ntawd, nb - iot pab kiag li no tuaj yeem muab kev nkag tau zoo dua ntawm cov tsev thiab cov nyom. Qhov no kuj txhais tau tias nb - iot cov cuab yeej tsis tuaj yeem xa cov ntaub ntawv ntau li LATE Cat M1.
Cov ntawv thov feem ntau ntawm NB - iot suav nrog cov ntawv thov siv hluav taws xob ntse, xws li lwm yam chaw taws teeb, thiab lwm yam chaw taws teeb pom kev uas xa cov ntaub ntawv tsis hnov ​​lus lossis ntau qhov ntau. Qhov no suav nrog kev tswj hwm HVAC, cov saib xyuas kev lag luam thiab cov sension ua liaj ua teb uas saib xyuas cov dej khov kho thiab ntes.
