Raws li Internet ntawm Yam (IoT) txuas ntxiv mus, cov txheej txheem sib txuas lus sib txawv ua lub luag haujlwm tseem ceeb hauv ntau yam kev thov. LoRaWAN thiab WiFi (tshwj xeeb tshaj yog WiFi HaLow) yog ob lub thev naus laus zis tseem ceeb siv hauv kev sib txuas lus IoT, txhua qhov muab qhov zoo sib xws rau cov kev xav tau tshwj xeeb. Kab lus no piv LoRaWAN thiab WiFi, pab koj xaiv txoj kev daws teeb meem rau koj qhov project IoT.
1. Kev Sib Txuas Lus: LoRaWAN vs WiFi
LoRaWAN: Paub txog nws qhov tshwj xeeb ntev-ntev muaj peev xwm, LoRaWAN yog qhov zoo tagnrho rau cov ntawv thov xav tau cov ntaub ntawv xa mus ntev. Hauv cov cheeb tsam nyob deb nroog, LoRaWAN tuaj yeem ncav cuag qhov deb ntawm 15-20 mais, thaum nyob hauv nroog ib puag ncig, nws npog 2-5 mais. Qhov no ua rau nws mus rau kev xaiv rau kev ua liaj ua teb ntse, kev saib xyuas tej thaj chaw deb, thiab lwm yam xwm txheej uas xav tau kev pabcuam dav dav.
WiFi: Tus qauv WiFi muaj kev sib txuas lus luv dua, txwv rau hauv cheeb tsam hauv zos. Txawm li cas los xij, WiFi HaLow txuas ntxiv mus txog li 1 km sab nraum zoov, txawm hais tias nws tseem poob qis piv rau LoRaWAN. Yog li, WiFi HaLow yog qhov haum rau luv luv rau nruab nrab-ntau IoT daim ntawv thov.
2. Cov ntaub ntawv hloov pauv tus nqi sib piv
LoRaWAN: LoRaWAN ua haujlwm nrog cov ntaub ntawv qis, feem ntau ntawm 0.3 kbps mus rau 50 kbps. Nws yog qhov zoo tshaj plaws rau cov ntawv thov uas tsis tas yuav muaj qhov bandwidth siab thiab tuaj yeem ua haujlwm nrog cov ntaub ntawv me me, xws li ib puag ncig sensors lossis cov ntsuas dej ntse.
WiFi HaLow: Ntawm qhov tod tes, WiFi HaLow muab cov ntaub ntawv hloov pauv ntau dua, ntawm 150 kbps mus rau ntau Mbps. Qhov no ua rau nws tsim nyog rau cov ntawv thov xav tau ntau dua bandwidth, xws li kev soj ntsuam video lossis cov ntaub ntawv nyuaj.
3. Kev siv hluav taws xob: LoRaWAN qhov zoo
LoRaWAN: Ib qho txiaj ntsig tseem ceeb ntawm LoRaWAN yog nws qhov kev siv hluav taws xob tsawg. Ntau LoRaWAN-raws li cov khoom siv tuaj yeem ua haujlwm tau ntau xyoo ntawm ib lub roj teeb, ua rau nws zoo tagnrho rau cov chaw taws teeb lossis nyuaj mus txog, xws li cov cuab yeej ua liaj ua teb lossis cov cuab yeej saib xyuas kev lag luam.
WiFi HaLow: Thaum WiFi HaLow muaj zog ntau dua li ib txwm WiFi, nws lub zog siv tseem siab dua LoRaWAN. WiFi HaLow yog li zoo dua rau IoT daim ntawv thov uas siv hluav taws xob tsis yog qhov kev txhawj xeeb loj, tab sis qhov sib npaug ntawm kev siv hluav taws xob thiab cov ntaub ntawv ntau dua yog xav tau.
4. Deployment Flexibility: LoRaWAN vs WiFi
LoRaWAN: LoRaWAN ua haujlwm nyob rau hauv qhov tsis muaj ntawv tso cai ntau zaus (xws li 868 MHz hauv Tebchaws Europe thiab 915 MHz hauv Asmeskas), txhais tau tias nws tuaj yeem siv tau yam tsis tas yuav muaj ntawv tso cai spectrum. Qhov no ua rau nws zoo tagnrho rau kev xa tawm loj hauv cov ntawv thov nyob deb nroog lossis kev lag luam IoT. Txawm li cas los xij, teeb tsa LoRaWAN network xav tau kev teeb tsa ntawm lub rooj vag thiab kev tsim kho vaj tse, uas yog qhov tsim nyog rau cov xwm txheej uas kev sib txuas lus ntev yog qhov tseem ceeb.
WiFi HaLow: WiFi HaLow sib koom ua ke yooj yim rau hauv cov txheej txheem WiFi uas twb muaj lawm, ua kom yooj yim rau kev xa tawm hauv ib puag ncig nrog WiFi network uas twb muaj lawm, xws li tsev thiab chaw ua haujlwm. Nws qhov ntev thiab cov ntaub ntawv ntau dua ua rau nws tsim nyog rau cov tsev ntse, muaj IoT, thiab cov ntawv siv zoo sib xws uas tsis muaj't xav tau kev sib txuas lus nyob deb.
5. Cov Kev Siv Ib txwm siv
LoRaWAN: LoRaWAN yog qhov zoo tshaj plaws rau kev siv ntev-ntev, tsis muaj zog, thiab cov ntaub ntawv-tus nqi qis, xws li:
- Kev ua liaj ua teb ntse (xws li kev saib xyuas av noo)
- Kev ntsuas hluav taws xob siv rau dej, roj, thiab cua sov
- Cov cuab tam tej thaj chaw deb nrhiav thiab saib xyuas
WiFi HaLow: WiFi HaLow yog qhov zoo dua rau luv luv rau nruab nrab-ntau daim ntawv thov uas xav tau cov ntaub ntawv ntau dua thiab kev pab them nqi zoo dua, xws li:
- Cov khoom siv hauv tsev ntse (xws li, lub koob yees duab kev ruaj ntseg, ntsuas kub)
- Muaj IoT ntaus ntawv saib xyuas
- Wearable Health and Fitness devices
Ob lub thev naus laus zis muaj lawv lub zog
Los ntawm kev sib piv LoRaWAN thiab WiFi, nws yog qhov tseeb tias ob lub thev naus laus zis muaj lawv qhov tshwj xeeb muaj zog hauv cov xwm txheej IoT sib txawv. LoRaWAN yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau kev sib txuas lus ntev, kev siv hluav taws xob tsawg, thiab cov ntaub ntawv me me. Ntawm qhov tod tes, WiFi HaLow ua tau zoo hauv cov xwm txheej uas cov ntaub ntawv ntau dua, kev sib txuas lus luv dua, thiab cov txheej txheem WiFi uas twb muaj lawm yog qhov tseem ceeb.
Kev xaiv txoj kev siv thev naus laus zis IoT yog nyob ntawm koj qhov kev xav tau tshwj xeeb. Yog tias koj qhov project xav tau cov ntaub ntawv xa mus rau cov chaw taws teeb uas tsis muaj zog thiab cov ntaub ntawv tsawg, LoRaWAN yog qhov zoo tagnrho. Yog tias xav tau cov ntaub ntawv siab dua thiab kev sib txuas lus luv dua, WiFi HaLow yog qhov kev xaiv zoo dua
Nkag siab qhov sib txawv ntawm LoRaWAN thiab WiFi HaLow tso cai rau koj xaiv cov cuab yeej sib txuas lus zoo tshaj plaws rau koj cov kev daws teeb meem IoT thiab tsav kev txhim kho kom zoo dua.
