Piv nrog rau NB-IoT thev naus laus zis, WiFi ultrasonic dej ntsuas muaj qee qhov zoo ntawm kev xa cov ntaub ntawv ceev, kev sib raug zoo hauv network, cov nqi xa tawm, thiab cov xwm txheej thov, raws li qhia hauv qab no:
- Kev xa cov ntaub ntawv sai: Feem ntau WiFi muaj qhov xa tau sai dua li NB-IoT. NB-IoT feem ntau yog siv rau IoT daim ntawv thov nrog cov ntaub ntawv qis, thiab nws cov ntaub ntawv xa tau feem ntau yog ntawm kaum tawm kbps thiab ntau pua kbps. Qhov sib piv, WiFi tuaj yeem ncav cuag qhov xa tau ntawm Mbps lossis txawm tias Gbps, ua rau muaj kev xa cov ntaub ntawv ntau sai dua, xws li cov ntaub ntawv siv dej tiag tiag thiab cov ntawv qhia txog kev siv dej kom ntxaws. Qhov no tso cai rau cov chaw tswj hwm lossis cov neeg siv kom tau txais cov ntaub ntawv dej tiav sai dua.
- Kev sib raug zoo hauv network: WiFi yog ib qho thev naus laus zis wireless network uas siv dav dav, thiab yuav luag txhua lub xov tooj ntse, ntsiav tshuaj, thiab khoos phis tawj txhawb nqa kev sib txuas WiFi. Yog li ntawd, WiFi ultrasonic dej meters tuaj yeem txuas ncaj qha thiab sib txuas lus nrog cov khoom siv no yam tsis tas yuav siv cov khoom siv tshwj xeeb lossis cov khoom siv hloov pauv. Qhov no pab cov neeg siv ua qhov kev saib xyuas thiab kev tswj hwm tiag tiag los ntawm cov apps mobile lossis cov khoos phis tawj. Qhov sib piv, NB-IoT cov khoom siv xav tau cov NB-IoT modules tshwj xeeb thiab kev txhawb nqa network, ua rau muaj kev sib raug zoo tsis zoo.
- Tus nqi qis thaum pib xa tawm: Hauv cov cheeb tsam uas twb muaj WiFi network lawm, xws li cov tsev, cov chaw ua haujlwm, thiab cov zej zog nyob, kev siv WiFi ultrasonic dej meters tsis tas yuav tsim lub network sib txuas lus sib cais. Lawv tuaj yeem siv cov khoom siv WiFi uas twb muaj lawm ncaj qha, txo tus nqi xa tawm thaum pib. Txawm hais tias tus nqi ntawm NB-IoT modules pheej poob qis, lawv tseem vam khom kev pabcuam network ntawm cov neeg teb xov tooj. Hauv cov cheeb tsam uas tsis muaj kev pabcuam network, kev nqis peev ntxiv yuav tsum tau txhim kho cov teeb liab lossis tsim cov chaw nres tsheb.
- Haum rau cov xwm txheej xa cov ntaub ntawv ceev ceev luv luv: Hauv cov chaw me me, xws li cov tsev thiab cov chaw lag luam me, WiFi ultrasonic dej ntsuas tuaj yeem ua tau raws li qhov xav tau ntawm kev xa cov ntaub ntawv ceev ceev luv luv. Hauv cov xwm txheej no, lub peev xwm npog thaj chaw dav dav ntawm NB-IoT tsis tsim nyog, thiab qhov zoo ntawm WiFi hauv kev sib txuas lus luv luv tuaj yeem siv tau zoo dua los muab cov kev pabcuam xa cov ntaub ntawv ruaj khov thiab ceev.
- Kev pab kom muaj kev sib txuas ntawm cov khoom siv: WiFi network txhawb kev sib txuas ntawm ntau lub cuab yeej tib lub sijhawm thiab tuaj yeem ua tiav kev sib txuas ntawm cov khoom siv. WiFi ultrasonic dej meters tuaj yeem txuas thiab sib qhia cov ntaub ntawv nrog lwm cov khoom siv ntse hauv tsev lossis tsev, xws li cov ntsuas hluav taws xob ntse, cov ntsuas roj ntse, thiab cov tshuab hauv tsev ntse. Qhov no ua rau muaj kev tswj hwm ntse thiab kev saib xyuas lub zog ntau dua. Qhov sib piv, NB-IoT feem ntau tsom mus rau kev sib txuas lus ntawm cov khoom siv thiab huab, thiab kev sib txuas ntawm cov khoom siv yog qhov nyuaj heev.
