Indlela yohlobo lokhuphiswano iyoyikeka. I-Bluetooth, i-Wi-Fi, kunye ne-Thread zonke zibeke izinto zabo kwi-IoT yamandla aphantsi. Okubalulekileyo, le migangatho ibe neenzuzo zokujonga into esebenzileyo kunye nengakhange isebenzele iZigBee, ukwandisa amathuba abo okuphumelela kunye nokunciphisa ixesha elifunekayo ukuphuhlisa isisombululo esisebenzayo.
Umsonto uyilwe ukusuka phantsi ukuya phezulu ukuze usebenze kwiimfuno ze-IoT enyanzelwa luncedo. Ukusetyenziswa kwamandla aphantsi, i-mesh topology, inkxaso ye-IP yemveli, kunye nokhuseleko olulungileyo ziimpawu eziphambili zomgangatho. Iphuhliswe ngabaninzi abathambekele ekuthatheni eyona ZigBee kwaye baphucule kuyo. Isitshixo kwisicwangciso se-Thread kukuphela-to-ekupheleni kwenkxaso ye-IP kwaye leyo yi-pribition likhaya elihlakaniphile, kodwa akukho sizathu sokukholelwa ukuba iya kumisa apho ukuba iphumelele.
IBluetooth kunye neWi-Fi zinokuba yingozi ngakumbi kwiZigBee. IBluetooth yaqala ukulungiselela ukujongana nemarike ye-IoT ubuncinci kwiminyaka emithandathu edlulileyo xa bongeza iBluetooth Low Energy kwinguqulo ye-4.0 yenkcazo engundoqo kwaye kamva kulo nyaka ukuhlaziywa kwe-5.0 kuya kwongeza uluhlu olwandisiweyo kunye nesantya, ukusombulula iintsilelo eziphambili. Ngexesha elifanayo, i-Blurtooth SIG iya kwazisa imigangatho yothungelwano lwe-mesh, eya kuba ngasemva iyahambelana ne-silicon eyenzelwe i-4.0 verion ye-spec. Iingxelo zibonisa ukuba inguqulo yokuqala ye-Blurtooth mesh iya kuba yi-application-powered-powered applications ezifana nokukhanyisa, i-markettraget market yokuqala yeBluetooth Mesh. Uguqulelo lwesibini lomgangatho womnatha luya kongeza amandla omzila, ukuvumela iindawo zamagqabi ezinamandla aphantsi ukuba zihlale zilele ngelixa ezinye (ngethemba lokuba ii-mains-powered) iinodi zenza umyalezo wokuphatha.
I-Wi-Fi Alliance isemva kwexesha kwiqela le-IoT elinamandla aphantsi, kodwa njenge-Blurtooth, inokwaziwa ngophawu oluqhelekileyo kunye ne-ecosystem enkulu ukuyinceda ukuba ikhawuleze. I-Wi-Fi Alliance ibhengeze i-Halow, eyakhiwe kumgangatho osezantsi we-Ghz 802.11ah, ngoJanuwari 2016 njengokungena kwabo kwimigangatho egcweleyo ye-IoT. I-Holaw inemiqobo enzima ekufuneka yoyiswe. Ukucaciswa kwe-802.11ah akukavunywa kwaye inkqubo ye-Halow certification ayilindelekanga kude kube yi-2018, ngoko yiminyaka emva kwemigangatho ekhuphisanayo. Okubaluleke ngakumbi, ukuze kusetyenziswe amandla e-Wi-Fi ecosystem, i-Halow idinga isiseko esikhulu esifakelweyo seendawo zokufikelela kwi-Wi-Fi ezixhasa i-802.11ah. Oko kuthetha ukuba abenzi bamasango e-broadband, iirotha ezingenazintambo, kunye neendawo zokufikelela kufuneka bongeze ibhendi entsha ye-spectrum kwiimveliso zabo, ukongeza iindleko kunye nobunzima. Kwaye iibhendi ze-sub-Ghz azikho jikelele njengebhendi ye-2.4GHz, ngoko ke abavelisi kuya kufuneka baqonde i-idiosyncrasies yolawulo lwamazwe amaninzi kwiimveliso zabo. Ngaba oko kuya kwenzeka? Mhlawumbi. Ngaba kuya kwenzeka ngexesha lokuba iHalow iphumelele? Ixesha liza kuxela.
Abanye bayayigxotha iBluetooth kunye ne-Wi-Fi njengabanxibelelanisi bamva nje kwimarike abangayiqondi kwaye abaxhotyiswanga ukujongana nayo. Yimpazamo leyo. Imbali yoqhagamshelo igcwele izidumbu zabantu ababambeleyo, imigangatho ephezulu yetekhnoloji eye yaneshwangusha lokuba kumendo wonxibelelwano lwebhemothi efana ne-Ethernrt, i-USB, iWi-Fi, okanye iBluetooth. Ezi "ntlobo ezihlaselayo" zisebenzisa amandla esiseko sazo esifakelweyo ukuze zithole inzuzo ekhuphisanayo kwiimarike ezihambelanayo, ukusebenzisana kweteknoloji yabakhuphisana nabo kunye nokunyusa uqoqosho lwesikali ukutyumza inkcaso. (Njengomvangeli wangaphambili we-FireWire, umbhali uyazi kabuhlungu amandla aguqukayo.)
