(Zidziwitso za Mkonzi: Nkhaniyi, yochokera ku ZigBee Resource Guide.)
Njira ya mpikisano ndiyowopsa.Bluetooth, Wi-Fi, ndi Thread onse ayika chidwi chawo pa IoT yamphamvu yotsika.Chofunika kwambiri, mfundozi zakhala ndi ubwino wowona zomwe zagwira ntchito ndi zomwe sizinagwire ntchito kwa ZigBee, kuonjezera mwayi wawo wopambana ndikuchepetsa nthawi yofunikira kuti apange yankho lothandiza.
Ulusi udapangidwa kuchokera pansi kuti uthandizire zosowa za IoT yomwe ili ndi zida.Kugwiritsa ntchito mphamvu pang'ono, mesh topology, chithandizo chamtundu wa IP, komanso chitetezo chabwino ndizomwe zili mulingo.Popeza apangidwa ndi ambiri omwe amakonda kutenga ZigBee zabwino kwambiri ndikuwongolera.Chinsinsi cha njira ya Thread ndikutha-to-mapeto thandizo la IP ndipo ndiye kubisala ndi nyumba yanzeru, koma palibe chifukwa chokhulupirira kuti idzayima pamenepo ngati itapambana.
Bluetooth ndi Wi-Fi zitha kukhala zodetsa nkhawa kwambiri kwa ZigBee.Bluetooth idayamba kukonzekera kuthana ndi msika wa IoT osachepera zaka zisanu ndi chimodzi zapitazo pomwe adawonjezera Bluetooth Low Energy ku mtundu wa 4.0 wazomwe zidakhazikitsidwa ndipo pambuyo pake chaka chino kukonzanso kwa 5.0 kudzawonjezera kuchuluka ndi liwiro, kuthetsa zolakwa zazikulu.Pa nthawi yomweyi, Blurtooth SIG idzayambitsa ma mesh networking miyezo, yomwe idzakhala kumbuyo yogwirizana ndi silicon yopangidwira 4.0 verion ya spec.Malipoti akuwonetsa kuti mtundu woyamba wa Blurtooth mesh udzakhala ntchito zoyendetsedwa ndi kusefukira kwa madzi monga kuyatsa, msika woyambilira wa Bluetooth Mesh.Mtundu wachiwiri wa mulingo wa ma mesh udzawonjezera kuthekera kolowera, kulola masamba amphamvu otsika kukhala akugona pomwe ma node ena (mwachiyembekezo oyendetsedwa ndi mains) amagwira ntchito.
Wi-Fi Alliance yachedwa ku chipani cha IoT chochepa mphamvu, koma monga Blurtooth, ili ndi chidziwitso chodziwika bwino komanso chilengedwe chachikulu chothandizira kuti chifulumire mwachangu.Wi-Fi Alliance idalengeza za Halow, yomangidwa pamtundu wa Ghz 802.11ah, mu Januwale 2016 monga kulowa kwawo mumiyezo yodzaza ya IoT.Holaw ali ndi zopinga zazikulu zoti athetse.Mafotokozedwe a 802.11ah sanavomerezedwe ndipo pulogalamu ya certification ya Halow sikuyembekezeka mpaka 2018, chifukwa chake kwatsala zaka zambiri kupikisana nawo.Chofunika kwambiri, kuti muthe kupititsa patsogolo mphamvu ya chilengedwe cha Wi-Fi, Halow amafunikira maziko oyikapo a Wi-Fi omwe amathandizira 802.11ah.Izi zikutanthauza kuti opanga zipata za Broadband, ma routers opanda zingwe, ndi malo olowera ayenera kuwonjezera gulu latsopano lazinthu zawo, ndikuwonjezera mtengo ndi zovuta.Ndipo magulu a sub-Ghz sali onse ngati gulu la 2.4GHz, kotero opanga adzafunika kumvetsetsa zowongolera zamayiko ambiri pazogulitsa zawo.Kodi zimenezo zidzachitika?Mwina.Kodi zidzachitika munthawi yake kuti Halow apambane?Nthawi idzanena.
Ena amachotsa Bluetooth ndi Wi-Fi ngati olumikizana posachedwa pamsika omwe sakumvetsetsa ndipo alibe zida zoyankhulirana.Kumeneko ndi kulakwitsa.Mbiri yolumikizana imadzaza ndi mitembo yaukadaulo, yapamwamba kwambiri yaukadaulo yomwe yakhala ndi tsoka lokhala panjira yolumikizana ndi behemoth monga Ethernrt, USB, Wi-Fi, kapena Bluetooth."Zamoyo zowononga" izi zimagwiritsa ntchito mphamvu zomwe zidakhazikitsidwa kuti zipeze mwayi wopikisana nawo m'misika yolumikizirana, kutengera luso la omwe akupikisana nawo ndikukulitsa chuma chambiri kuti athetse otsutsa.(Monga mlaliki wakale wa FireWire, wolembayo akudziwa momvetsa chisoni za mphamvuyi.)
