Narrowband-internet yezvinhu (NB-IIH) ndeyekuwedzera kutsva-kutsanya Wirelest tekinoroji tekinoroji yakaunzwa Yakaverengerwa se10G tekinoroji, yakaenzana ne 3GPP muna 2016. Icho chiyero-chakavakirwa pasi simba nzvimbo (LPWA) tekinoroji yakagadzirwa kuti iite huwandu hwakawanda hwekuita huwandu hwetsiva hweIHI. NB-IIH inotakura inovandudza mashandiro emagetsi emushandisirwo emushandisi, system kugona uye spectrum inoshanda, kunyanya mukuvhara kwakadzika. Hupenyu hwebhatiri hwemakore anopfuura gumi hunogona kutsigirwa kune dzakasiyana siyana dzekushandisa.
Nyowani dziripo dziripo uye zviteshi zvakagadzirirwa kusangana nezvinodiwa zvinodikanwa zveKuwedzeredzwa kwekupedzisira Kutanga mutengo weNB-IOT modules inotarisirwa kuve yakafanana neGSM / GPRS. Iyo yekuisa tekinoroji ndiyo yakanyanya nyore kupfuura yanhasi GSM / GPRS uye mutengo wayo unotarisirwa kuderedza nekukurumidza sekuda kunowedzera.
Yakatsigirwa neese makuru mbozha midziyo, chipset uye module vagadziri, NB-IIH inogona kuvapo ne 2G, 3G, uye 4G mobile network. Izvo zvakare zvinobatsira kubva kuchengetedzeka kwese uye zvakavanzika zvefoni mbozha, sekutsigirwa kwemushandisi kuzivikanwa kwekuvanzika, kusimbiswa, kuvanzika, kutendeka kwedata, uye nharembozha yekuzivikanwa. Iyo yekutanga NB-IIH-IIH COMPRICE YAKAITWA UYE GLOBAL LUL OUT inotarisirwa muna 2017/18.
Ndeipi mhando yeNB-IIH?
NB-ot inogonesa kutumirwa kwezvinhu zvakaderera zvakaderera mune manhamba makuru (anenge makumi mashanu ezviuru zvimakumi mashanu ezvibvumirano paCell). Iyo sero renzvimbo inogona kubva 40km kusvika 100km. Izvi zvinobvumira maindasitiri seanobatsira, Asset manejimendi, logistics uye flet manejimendi kuti vabatanidze sensors, vatengesi uye masheti emitauro yakafukidza iyo yakafukidza nzvimbo yakawandisa.
NB-IHIT inopa iyo yakadzika yekuvhara (164DB) pane yakawanda yeLPwan tekinoroji uye 20DB inopfuura kupfuura kujairika GSM / GPRS.
Ndezvinetso zvipi zvinokanganisa NB-IIH
Iyi tekinoroji yakagadzirirwa kusangana nezvinodiwa pakuwedzera kufukidzwa nekushandiswa kwakadzika kwesimba. Midziyo inogona kuve yakagadzirirwa kwenguva yakareba pane imwe bhatiri. NB-IIHT inogona kuiswa pachena uchishandisa iripo uye yakavimbika cellular incarsture.
NB-IIT zvakare ine iyo yekuchengetedza zvinhu zviripo muLTE Cellular Networks, yakadai sekudzivirira chiratidzo, kuchengetedzwa kwechokwadi uye data kunyorera. Inoshandiswa pamwe chete neyekuchengeterwa APN, inogadzira mudziyo wekubatanidza manejimendi akareruka uye akachengeteka.
