Indlela yohlobo lomncintiswano iyamangalisa.I-Bluetooth, i-Wi-Fi, ne-Thread zonke zibeke izinto ezibonwayo ku-IoT enamandla aphansi.Okubalulekile, lawa mazinga abe nezinzuzo zokubheka okusebenzile nalokho okungazange kusebenzele i-ZigBee, okwandisa amathuba abo okuphumelela kanye nokunciphisa isikhathi esidingekayo ukuze kuthuthukiswe isixazululo esisebenzayo.
Uchungechunge lwaklanywa kusukela phansi kuya phezulu ukuze lunikeze izidingo ze-IoT ecindezelwe yinsiza .Ukusetshenziswa kwamandla okuphansi, i-mesh topology, ukwesekwa kwe-IP yomdabu, nokuphepha okuhle yizici ezibalulekile zezinga.Njengoba ithuthukiswe abaningi abavame ukuthatha okungcono kakhulu kwe-ZigBee futhi bathuthuke kukho.Ukhiye wesu le-Thread ukusekelwa kwe-IP yokuphela-kuya-ekupheleni futhi lokho kuyinkambiso ikhaya elihlakaniphile, kodwa asikho isizathu sokukholelwa ukuthi izoma lapho uma iphumelela.
I-Bluetooth ne-Wi-Fi kungenzeka kukhathaze kakhulu i-ZigBee.I-Bluetooth yaqala ukulungiselela ukubhekana nemakethe ye-IoT okungenani eminyakeni eyisithupha edlule lapho ingeza i-Bluetooth Low Energy enguqulweni engu-4.0 yencazelo eyinhloko futhi kamuva kulo nyaka ukubuyekezwa kwe-5.0 kuzokwengeza ububanzi obukhulayo nesivinini, kuxazululwe ukushiyeka okubalulekile.Cishe ngaso leso sikhathi, i-Blurtooth SIG izokwethula izindinganiso zokuxhumana ze-mesh, ezizobuyela emuva zihambisane ne-silicon eyenzelwe inguqulo engu-4.0 ye-spec.Imibiko ibonisa ukuthi inguqulo yokuqala ye-Blurtooth mesh izoba izinhlelo zokusebenza ezinamandla ezikhukhula ezifana nokukhanyisa, imakethe ye-traget yangaphambi kwesikhathi ye-Bluetooth Mesh.Inguqulo yesibili yezinga lemeshi izongeza amandla omzila, ivumele izindawo zamaqabunga ezinamandla amancane ukuthi zihlale zilele kuyilapho amanye (ngethemba lokuthi ama-main-powered) amanodi enza ukuphatha umlayezo.
I-Wi-Fi Alliance ifike sekwephuzile ephathini ye-IoT enamandla aphansi, kodwa njenge-Blurtooth, inokubonwa komkhiqizo okuyindawo yonke kanye ne-ecosystem enkulu yokusiza ukuyiletha ngokushesha.I-Wi-Fi Alliance imemezele i-Halow, eyakhelwe ezingeni eliphansi le-Ghz 802.11ah, ngoJanuwari 2016 njengokungena kwabo emazingeni agcwele e-IoT.U-Holaw unezithiyo ezinzima okufanele azinqobe.Ukucaciswa kwe-802.11ah kusazovunywa futhi uhlelo lwesitifiketi se-Halow akulindelekile kuze kube ngu-2018, ngakho-ke sekuyiminyaka ngemuva kwamazinga aqhudelanayo.Okubaluleke nakakhulu, ukuze kusetshenziswe amandla e-ecosystem ye-Wi-Fi, i-Halow idinga isisekelo esikhulu esifakiwe sezindawo zokufinyelela ze-Wi-Fi ezisekela u-802.11ah.Lokho kusho ukuthi abakhi bamasango e-broadband, amarutha angenawaya, nezindawo zokufinyelela kudingeka bengeze ibhendi ye-spectrum entsha emikhiqizweni yabo, bengeze izindleko nobunkimbinkimbi.Futhi amabhendi e-sub-Ghz awafani nebhendi ye-2.4GHz, ngakho abakhiqizi bazodinga ukuqonda ama-idiosyncrasies okulawula amazwe amaningi emikhiqizweni yawo.Ingabe lokho kuzokwenzeka?Mhlawumbe.Ngabe kuzokwenzeka ngokuhamba kwesikhathi ukuthi iHalow iphumelele?Isikhathi sizosho.
Abanye bachitha i-Bluetooth ne-Wi-Fi njengabaxhumani bakamuva emakethe abangayiqondi futhi abangahlonyiselwe ukubhekana nayo.Lokho kuyiphutha.Umlando wokuxhumana ugcwele izidumbu zamazinga akhona, aphakeme kakhulu kwezobuchwepheshe abe neshwa lokuba sendleleni yokuxhuma ibhemoth efana ne-Ethernrt, i-USB, i-Wi-Fi, noma i-Bluetooth.Lezi "zinhlobo ezihlaselayo" zisebenzisa amandla esisekelo sazo esifakiwe ukuze zithole inzuzo yokuncintisana ezimakethe ezihlangene, zikhetha ubuchwepheshe bezimbangi zazo kanye nomnotho osebenzayo wokuqeda ukuphikiswa.(Njengomshumayeli wangaphambili we-FireWire, umbhali uyazi kabuhlungu ngokuguqukayo.)
