Pamene intaneti ya Zinthu (IoT) ikupitilirabe kusinthika, ma protocol osiyanasiyana olankhulirana amakhala ndi gawo lofunikira pamachitidwe osiyanasiyana ogwiritsira ntchito. LoRaWAN ndi WiFi (makamaka WiFi HaLow) ndi matekinoloje awiri otchuka omwe amagwiritsidwa ntchito polumikizirana ndi IoT, iliyonse ikupereka maubwino apadera pazosowa zapadera. Nkhaniyi ikufanizira LoRaWAN ndi WiFi, kukuthandizani kusankha njira yoyenera ya polojekiti yanu ya IoT.
1. Njira Yolumikizirana: LoRaWAN vs WiFi
LoRaWAN: LoRaWAN imadziwika ndi kuthekera kwake kwautali wautali, ndi yabwino kwa mapulogalamu omwe amafunikira kutumizirana ma data mtunda wautali. M'madera akumidzi, LoRaWAN imatha kufika mtunda wa makilomita 15-20, pamene m'madera akumidzi, imakhala makilomita 2-5. Izi zimapangitsa kukhala chisankho chosankha paulimi wanzeru, kuyang'anira kutali, ndi zochitika zina zomwe zimafunikira kufalitsa kwambiri.
WiFi: Ma WiFi wamba ali ndi njira yolumikizirana yofupikitsa, yocheperako pama network amderalo. Komabe, WiFi HaLow imakulitsa mtunda mpaka pafupifupi 1 kilomita kunja, ngakhale ikadali yochepa poyerekeza ndi LoRaWAN. Chifukwa chake, WiFi HaLow ndiyoyenera kugwiritsa ntchito IoT yaifupi kapena yapakatikati.
2. Kufananiza kwa Kutumiza kwa Data
LoRaWAN: LoRaWAN imagwira ntchito ndi ma data otsika, nthawi zambiri kuyambira 0.3 kbps mpaka 50 kbps. Ndizoyenerana ndi mapulogalamu omwe safuna bandwidth yapamwamba ndipo amatha kugwira ntchito pafupipafupi, kutumiza ma data ang'onoang'ono, monga masensa a chilengedwe kapena mamita amadzi anzeru.
WiFi HaLow: Kumbali inayi, WiFi HaLow imapereka mitengo yapamwamba kwambiri yotengera deta, kuchokera pa 150 kbps kupita ku Mbps zingapo. Izi zimapangitsa kuti zikhale zoyenera kwa mapulogalamu omwe amafunikira bandwidth apamwamba, monga kuyang'anira kanema kapena kufalitsa deta zovuta.
3. Kugwiritsa Ntchito Mphamvu: Ubwino wa LoRaWAN
LoRaWAN: Ubwino umodzi wofunikira wa LoRaWAN ndikugwiritsa ntchito mphamvu zochepa. Zipangizo zambiri zochokera ku LoRaWAN zimatha kugwira ntchito kwa zaka zingapo pa batri imodzi, zomwe zimapangitsa kuti zikhale zoyenera kumadera akutali kapena ovuta kufika, monga zowunikira zaulimi kapena zida zowunikira mafakitale.
WiFi HaLow: Ngakhale WiFi HaLow ndiyogwiritsa ntchito mphamvu zambiri kuposa WiFi yachikhalidwe, kugwiritsa ntchito kwake mphamvu kumakhalabe kwakukulu kuposa LoRaWAN. Chifukwa chake WiFi HaLow ndiyoyenera kugwiritsa ntchito IoT pomwe kugwiritsa ntchito mphamvu sizovuta kwambiri, koma kulinganiza pakati pakugwiritsa ntchito mphamvu zamagetsi ndi kuchuluka kwa data kumafunika.
4. Kusinthasintha kwa Kutumiza: LoRaWAN vs WiFi
LoRaWAN: LoRaWAN imagwira ntchito m'mabandi osavomerezeka (monga 868 MHz ku Europe ndi 915 MHz ku US), kutanthauza kuti ikhoza kutumizidwa popanda kufunikira kwa zilolezo za sipekitiramu. Izi zimapangitsa kukhala koyenera kutumizidwa kwakukulu kumidzi kapena mafakitale a IoT. Komabe, kukhazikitsa netiweki ya LoRaWAN kumafuna kukhazikitsa zipata ndi zomangamanga, zomwe ndizofunikira pazochitika zomwe kulumikizana kwautali ndikofunikira.
WiFi HaLow: WiFi HaLow imaphatikizana mosavuta ndi zida za WiFi zomwe zilipo, kupangitsa kuti kutumiza kuzikhala kosavuta m'malo okhala ndi maukonde a WiFi omwe alipo, monga nyumba ndi maofesi. Kutalika kwake komanso kuchuluka kwa data kumapangitsa kuti ikhale yoyenera nyumba zanzeru, IoT yamafakitale, ndi mapulogalamu ofanana omwe samatero't amafuna kulankhulana mtunda wautali.
5. Milandu Yomwe Imagwiritsidwira Ntchito
LoRaWAN: LoRaWAN ndiyabwino kugwiritsa ntchito nthawi yayitali, yamphamvu yochepa, komanso yotsika kwambiri, monga:
- Ulimi wanzeru (mwachitsanzo, kuyang'anira chinyezi m'nthaka)
- Kugwiritsa ntchito mita pamadzi, gasi, ndi kutentha
- Kutsata ndi kuyang'anira katundu wakutali
WiFi HaLow: WiFi HaLow ndiyoyenera kugwiritsa ntchito zazifupi mpaka zapakatikati zomwe zimafuna mitengo yayikulu ya data komanso kuphimba bwino, monga:
- Zida zanzeru zakunyumba (mwachitsanzo, makamera achitetezo, ma thermostats)
- Kuwunika kwa zida za Industrial IoT
- Zida zovala zathanzi komanso zolimbitsa thupi
Matekinoloje Onsewa Ali Ndi Mphamvu Zawo
Poyerekeza LoRaWAN ndi WiFi, zikuwonekeratu kuti matekinoloje onsewa ali ndi mphamvu zapadera pamachitidwe osiyanasiyana a IoT. LoRaWAN ndiye chisankho chabwino kwambiri pamapulogalamu omwe amafunikira kulumikizana kwautali, kugwiritsa ntchito mphamvu zochepa, komanso kutumizirana ma data ang'onoang'ono. Kumbali ina, WiFi HaLow imapambana m'malo omwe mitengo yapamwamba ya data, maulendo afupikitsa olankhulana, ndi zida za WiFi zomwe zilipo ndizofunika.
Kusankha ukadaulo wolumikizana wa IoT woyenera zimatengera zosowa zanu zenizeni. Ngati polojekiti yanu ikufuna kutumiza deta yakutali ndi mphamvu zochepa komanso zofunikira zochepa za deta, LoRaWAN ndi yabwino. Ngati ma data apamwamba komanso njira zazifupi zolumikizirana zikufunika, WiFi HaLow ndiye njira yabwinoko
Kumvetsetsa kusiyana pakati pa LoRaWAN ndi WiFi HaLow kumakupatsani mwayi wosankha njira yabwino kwambiri yolumikizirana ndi yankho la IoT ndikuyendetsa chitukuko bwino.
