Tekinolosia wireless Zigbee, WiFi mo 433MHz honau ngaahi ʻulungaanga

Zigbee, Ko e WiFi mo e 433MHz ko ha ngaahi tekinolosia kehekehe ʻe tolu ki he fetuʻutaki wireless. ʻOku maʻu ʻe he tekinolosia takitaha hono e kau palofesinale mo e e kovi.

Ko e Zigbee ko ha malohi maʻulalo, falalaʻanga ʻaupito, tekinolosia ʻo e netiueka (wireless nailoni). ʻI hono fakaʻaongaʻi ʻo e routers, ʻOku ʻikai ngata pe ʻi he lava ke fakalahi mo fakatonutonu ʻa e feituʻu ʻoku ʻi ai e netiueka, ka ʻe lava foki ke toʻo ʻa e "feituʻu kui" ʻi he ʻatakai ʻo e fetuʻutaki wireless. ʻIkai ngata ai, ʻOku poupouʻi ʻe Zigbee ʻa e fetuʻu, fuʻu ʻakau mo e nailoni topologies. Ko ia, ʻOku feʻunga lelei ʻa e Zigbee mo e ʻatakai faingofua mo faingataʻa fakatouʻosi. Fakafehoanaki ki he WiFi, neongo ia, Ko e vave ʻo e fakamatala ʻa Zigbee ko e 250kbps, maʻulalo ange ʻi he 11Mbps-54Mbps. ʻOku ne ʻai Zigbee taʻefeʻunga ki hono fakaʻaongaʻi ʻo e fakamatala maʻolunga, hange ko e fanifo ʻi he ʻInitaneti, faile lahi ʻoku download pe upload. Ki he falekai mo e ngaahi ngaue ki he meʻakai, neongo ia, ʻOku siʻisiʻi pe ʻa e paʻanga ʻoku fakafetongi ʻi he vahaʻa ʻo e server mo e feituʻu. Ko ia, Ko e Zigbee ko ha tekinolosia feʻunga ia ki hono ʻota ʻo e tohi kole.

ʻE lava ke poupouʻi ʻe he WiFi ʻa e ngaahi polokalama ʻoku maʻolunga hono fakaʻaongaʻi. ʻOku ne toe poupouʻi foki ʻa e konga "maʻu pe", ʻa ia ʻoku ne ʻai ke matamatalelei ʻa e WiFi ki ha ngaahi polokalama ʻe niʻihi. Neongo ia, ʻOku ʻi ai ha drawbacks kuo fakatokangaʻi ʻe he consumers, hange ko e fakaʻauha ʻo e malohi maʻolunga, ala falalaʻanga maʻulalo, taimi loloa ʻo e fetuʻutaki, etc.

433Kuo lahi hono fakaʻaongaʻi ʻo e tekinolosia MHz ʻi Siaina ki hono ʻota ʻo e falekai. Koeʻuhi ʻoku ne fakaʻaongaʻi ʻa e tuʻo lahi ʻo e tameʻa, ʻe lava ke ʻave ʻene fakaʻilonga wireless ʻo lahi ange ʻi Zigbee mo e WiFi, ʻa ia ʻoku ngaue ʻi 2.4 GHz band. Neongo ia, Ko e lahi ʻo e fakamatala ʻo e 433MHz ko e 9.6 kbps, maʻulalo ange ʻi he vave ʻo e fakamatala ʻa e WiFi mo e Zigbee. Ko ia, 433MHz suti ʻa e tohi kole ʻa ia ko e kiʻi fakamatala siʻisiʻi pe ʻoku fie maʻu ke ʻave. ʻIkai ngata ai, tatau pe mo e WiFi, 433ʻOku poupouʻi ʻe MHz ʻa e fetuʻu topology pe, ʻa ia te ne ala fakatupu ʻa e "feituʻu kui" ʻi he feituʻu ʻoku ʻi ai e netiueka wireless.

Kehe mei he founga "maʻu pe" ʻa e WiFi, ʻi Zigbee mo 433MHz System, ʻOku toki fokotuʻu pe ʻa e fehokotakiʻanga wireless ʻi he taimi ʻoku fie maʻu ai ke ʻave ʻa e fakamatala. ʻE lava ʻe he founga ko ʻeni ʻo fakasiʻisiʻi ʻa e kaunoa ki he ngaahi meʻangaue kehe ʻi he netiueka. ʻOku toe fakasiʻisiʻi foki mo e malohi ʻo e meʻangaue. Neongo ia, Kapau ʻoku kole ʻa e "maʻu pe" ʻi he Zigbee pe 433MHz System, ʻe lava ke fokotuʻutuʻu ha ngaue ʻi he polokalama fakakomipiuta ke poupouʻi ʻa e founga ko ʻeni.
