Hauv thaj tsam ntawm Is Taws Nem ntawm Yam (IoT), kev sib txuas lus tau zoo thiab ntev ntev yog qhov tseem ceeb. Ob lub ntsiab lus tseem ceeb uas feem ntau tshwm sim hauv cov ntsiab lus no yog LPWAN thiab LoRaWAN. Thaum lawv muaj kev cuam tshuam, lawv tsis zoo ib yam. Yog li, qhov txawv ntawm LPWAN thiab LoRaWAN yog dab tsi? Cia peb ua kom tawg.
To taub LPWAN
LPWAN sawv cev rau Low Power Wide Area Network. Nws yog ib hom wireless telecommunication network tsim los tso cai rau kev sib txuas lus ntev ntawm tus nqi qis ntawm cov khoom sib txuas, xws li cov sensors ua haujlwm ntawm lub roj teeb. Nov yog qee qhov tseem ceeb ntawm LPWAN:
- Kev siv hluav taws xob tsawg: LPWAN thev naus laus zis tau ua kom zoo rau kev siv hluav taws xob tsawg, ua kom cov khoom siv khiav ntawm cov roj teeb me me rau ntau xyoo.
- Ntev Ntev: LPWAN tes hauj lwm tuaj yeem npog thaj chaw loj, feem ntau yog nyob ntawm ob peb mais hauv nroog chaw mus txog kaum mais ntawm cov chaw nyob deb nroog.
- Tsawg Cov Ntaub Ntawv Tus Nqi: Cov tes hauj lwm no yog tsim los rau cov ntawv thov uas xav tau kev sib kis ntawm cov ntaub ntawv me me, xws li kev nyeem ntawv sensor.
Nkag siab LoRaWAN
LoRaWAN, ntawm qhov tod tes, yog hom tshwj xeeb ntawm LPWAN. Nws sawv cev rau Long Range Wide Area Network thiab yog cov txheej txheem tshwj xeeb uas tsim los rau wireless, roj teeb ua haujlwm hauv ib cheeb tsam, lub teb chaws, lossis thoob ntiaj teb network. Nov yog cov yam ntxwv tshwj xeeb ntawm LoRaWAN:
- Standardized raws tu qauv: LoRaWAN yog tus qauv kev sib txuas lus raws tu qauv tsim nyob rau sab saum toj ntawm LoRa (Long Range) lub cev txheej txheej, uas ua kom muaj kev sib cuam tshuam ntawm cov khoom siv thiab tes hauj lwm.
- Kev Pabcuam Dav Dav: Zoo ib yam li LPWAN, LoRaWAN muab kev pabcuam dav dav, muaj peev xwm sib txuas cov khoom siv mus ntev.
- Scalability: LoRaWAN txhawb nqa ntau lab ntawm cov khoom siv, ua rau nws muaj peev xwm loj heev rau kev xa tawm IoT loj.
- Kev ruaj ntseg: Cov txheej txheem suav nrog cov yam ntxwv muaj kev ruaj ntseg zoo, xws li qhov kawg-rau-kawg encryption, los tiv thaiv cov ntaub ntawv ncaj ncees thiab tsis pub leej twg paub.
Qhov txawv ntawm LPWAN thiab LoRaWAN
- Scope thiab Specificity:
- LPWAN: Hais txog ib pawg dav dav ntawm cov thev naus laus zis network tsim los rau lub zog qis thiab kev sib txuas lus ntev. Nws suav nrog ntau yam thev naus laus zis, suav nrog LoRaWAN, Sigfox, NB-IoT, thiab lwm yam.
- LoRaWAN: Ib qho kev siv thiab raws tu qauv hauv LPWAN qeb, siv LoRa thev naus laus zis.
- Technology thiab raws tu qauv:
- LPWAN: tuaj yeem siv cov thev naus laus zis thiab cov txheej txheem sib txawv. Piv txwv li, Sigfox thiab NB-IoT yog lwm hom LPWAN thev naus laus zis.
- LoRaWAN: Tshwj xeeb yog siv cov txheej txheem LoRa modulation thiab ua raws li LoRaWAN raws tu qauv rau kev sib txuas lus thiab kev tswj xyuas network.
- Standardization thiab Interoperability:
- LPWAN: Tej zaum los yog tsis ua raws li tus txheej txheem raws tu qauv nyob ntawm seb cov cuab yeej siv.
- LoRaWAN: Yog tus txheej txheem raws tu qauv, ua kom muaj kev sib cuam tshuam ntawm cov khoom siv sib txawv thiab cov tes hauj lwm uas siv LoRaWAN.
- Siv Case thiab Daim Ntawv Thov:
- LPWAN: Kev siv dav dav suav nrog ntau yam kev siv IoT uas xav tau lub zog qis thiab kev sib txuas lus ntev, xws li kev saib xyuas ib puag ncig, kev ua liaj ua teb ntse, thiab kev taug qab cov cuab tam.
- LoRaWAN: Tshwj xeeb yog tsom rau cov ntawv thov uas xav tau kev nyab xeeb, tuaj yeem ua tau, thiab kev sib txuas ntev ntev, xws li cov nroog ntse, muaj IoT, thiab cov tes hauj lwm loj loj.
Kev siv tswv yim
- LPWAN Technologies: Ua hauj lwm nyob rau hauv ntau yam ntawm IoT kev daws teeb meem, txhua tus haum rau cov kev xav tau tshwj xeeb. Piv txwv li, Sigfox feem ntau yog siv rau kev siv hluav taws xob tsawg thiab cov ntaub ntawv tsawg tsawg, thaum NB-IoT nyiam rau cov ntawv thov ntawm tes.
- LoRaWAN Networks: Siv dav hauv cov ntawv thov uas xav tau kev sib txuas lus ntev ntev thiab kev sib txuas lus yooj yim, xws li kev ntsuas ntse, teeb pom kev zoo, thiab kev saib xyuas kev ua liaj ua teb.
