Raws li Internet ntawm Yam (IoT) txuas ntxiv nthuav dav, cov thev naus laus zis tshiab tau tshwm sim los ua kom tau raws li qhov xav tau ntawm thaj chaw loj hlob no. Ob lub technologies zoo li no LoRa thiab BLE, uas tam sim no tau siv ua ke hauv ntau hom kev siv.
LoRa (luv luv rau Long Range) yog lub tshuab sib txuas lus wireless uas siv lub zog qis, qhov dav dav (LPWANs) txhawm rau txuas cov khoom siv mus ntev. Nws yog qhov zoo tagnrho rau IoT daim ntawv thov uas yuav tsum tau muaj bandwidth tsawg thiab lub roj teeb ntev, xws li kev ua liaj ua teb ntse, lub nroog ntse, thiab kev lag luam automation.
BLE (luv rau Bluetooth Tsis Muaj Zog) yog ib txoj kev sib txuas lus wireless uas siv cov xov tooj cua luv luv los txuas cov khoom siv. Nws yog feem ntau siv hauv cov neeg siv khoom siv hluav taws xob, xws li smartphones, qoj trackers, thiab smartwatches.
Los ntawm kev sib txuas ob lub thev naus laus zis no, cov neeg tsim khoom tuaj yeem tsim IoT daim ntawv thov uas yog ob qho tib si ntev thiab qis zog. Piv txwv li, daim ntawv thov hauv nroog ntse yuav siv LoRa los txuas cov sensors uas saib xyuas huab cua zoo, thaum siv BLE txuas mus rau smartphones lossis lwm yam khoom siv rau kev txheeb xyuas cov ntaub ntawv hauv lub sijhawm.
Lwm qhov piv txwv yog nyob rau hauv kev lag luam logistics, qhov twg LoRa tuaj yeem siv los taug qab cov khoom xa tuaj hla qhov deb, thaum BLE tuaj yeem siv los saib xyuas cov khoom ntawm ib tus neeg hauv kev xa khoom. Qhov no tuaj yeem pab cov tuam txhab logistics optimize lawv cov saw hlau thiab txo cov nqi.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv LoRa thiab BLE ua ke yog tias lawv yog ob qho tib si qhib qauv. Qhov no txhais tau hais tias cov neeg tsim khoom tau nkag mus rau ntau yam khoom siv kho vajtse thiab software, ua kom yooj yim los tsim cov kev cai IoT kev daws teeb meem.
Tsis tas li ntawd, ob lub thev naus laus zis tau tsim los ua lub zog qis, uas yog qhov tseem ceeb rau IoT daim ntawv thov uas tso siab rau cov khoom siv roj teeb. Qhov no txhais tau hais tias lawv tuaj yeem ua haujlwm rau lub sijhawm txuas ntxiv yam tsis tas yuav tsum tau them rov qab lossis hloov pauv.
Lwm qhov zoo dua yog qhov ntawd LoRa thiab BLE ob leeg muaj kev nyab xeeb heev. Lawv siv advanced encryption algorithms los tiv thaiv cov ntaub ntawv xa mus, kom ntseeg tau tias cov ntaub ntawv rhiab tau khaws cia zoo los ntawm hackers thiab lwm cov neeg siv tsis tau tso cai.
Zuag qhia tag nrho, kev sib xyaw ntawm LoRa thiab BLE tau ua pov thawj los ua ib qho cuab yeej muaj zog rau cov neeg tsim khoom tab tom nrhiav los tsim cov ntawv thov IoT tshiab. Raws li cov thev naus laus zis no txuas ntxiv mus ntxiv, peb tuaj yeem cia siab tias yuav pom ntau qhov kev siv zoo siab tshwm sim nyob rau xyoo tom ntej.
