Ukuze uhlanganise ikhaya elixhunyiwe, i-Wi-Fi ibhekwa njengokukhetha okutholakala yonke indawo. Kuhle ukuba nazo nge-Wi-Fi evikelekile. Lokho kungahambisana kalula ne-router yakho yasekhaya ekhona futhi akudingeki uthenge i-smart hub ehlukile ukuze ungeze amadivayisi kuyo.

Kodwa i-Wi-Fi nayo inemikhawulo yayo. Amadivayisi asebenza nge-Wi-Fi kuphela adinga ukushajwa njalo. Cabanga ngama-laptop, ama-smartphone, ngisho nezipikha ezihlakaniphile. Ngaphandle kwalokho, azikwazi ukuzithola futhi kufanele ufake iphasiwedi ngesandla yedivayisi ngayinye entsha ye-Wi-Fi. Uma ngesizathu esithile ijubane le-inthanethi liphansi, lingaguqula lonke ulwazi lwakho lwasekhaya oluhlakaniphile lube yiphupho elibi.

Ake sihlole izinzuzo kanye nokungalungi kokusebenzisa i-Zigbee noma i-Wi-Fi. Ukwazi lo mehluko kubalulekile ngoba kungathonya kakhulu izinqumo zakho zokuthenga imikhiqizo ethile yasekhaya ehlakaniphile.

1. Ukusetshenziswa Kwamandla

I-Zigbee ne-Wifi zombili ubuchwepheshe bokuxhumana obungenantambo obusekelwe ebhendini le-2.4GHz. Ekhaya elihlakaniphile, ikakhulukazi ekuhlakanipheni kwendlu yonke, ukukhetha iphrothokholi yokuxhumana kuthinta ngqo ubuqotho kanye nokuzinza komkhiqizo.

Uma kuqhathaniswa, i-Wifi isetshenziselwa ukudlulisa isivinini esikhulu, njengokufinyelela i-inthanethi engenantambo; i-Zigbee yenzelwe ukudlulisa isivinini esiphansi, njengokuxhumana kwezinto ezimbili ezihlakaniphile.

Kodwa-ke, lobu buchwepheshe obubili busekelwe ezindinganisweni ezahlukene ezingenantambo: I-Zigbee isekelwe ku-IEEE802.15.4, kanti i-Wifi isekelwe ku-IEEE802.11.

Umehluko ukuthi iZigbee, yize izinga lokudlulisa liphansi, eliphakeme kakhulu lingu-250kbps kuphela, kodwa ukusetshenziswa kwamandla kungu-5mA kuphela; Nakuba i-Wifi inezinga lokudlulisa eliphezulu, i-802.11b, isibonelo, ingafinyelela ku-11Mbps, kodwa ukusetshenziswa kwamandla kungu-10-50mA.

Ngakho-ke, ngokuxhumana kwekhaya elihlakaniphile, ukusetshenziswa kwamandla aphansi kusobala ukuthi kuyathandwa kakhulu, ngoba imikhiqizo efana nama-thermostat, okudingeka aqhutshwe ngamabhethri kuphela, ukwakheka kokusetshenziswa kwamandla kubaluleke kakhulu. Ngaphezu kwalokho, i-Zigbee inenzuzo esobala uma iqhathaniswa ne-Wifi, inani lama-node enethiwekhi liphezulu njenge-65,000; i-Wifi ingu-50 kuphela. I-Zigbee ingu-30 milliseconds, i-Wifi ingu-3seconds. Ngakho-ke, uyazi ukuthi kungani abathengisi abaningi bezindlu ezihlakaniphile bethanda i-Zigbee, futhi-ke i-Zigbee incintisana nezinto ezifana ne-Thread ne-Z-Wave.

2. Ukuhlalisana ndawonye

Njengoba i-Zigbee ne-Wifi zinezinzuzo nezingozi zazo, zingasetshenziswa yini ndawonye? Kufana nezinqubo ze-CAN ne-LIN ezimotweni, ngayinye isebenzela uhlelo oluhlukile.

Kuyenzeka ngokwethiyori, futhi ukuhambisana kuyafaneleka ukutadisha ngaphezu kokucatshangelwa kwezindleko. Ngenxa yokuthi zombili izindinganiso zisebhendini le-2.4ghz, zingaphazamisana uma zisetshenziswa ndawonye.

Ngakho-ke, uma ufuna ukusebenzisa i-Zigbee ne-Wifi ngesikhathi esisodwa, udinga ukwenza umsebenzi omuhle ekuhleleni isiteshi ukuqinisekisa ukuthi isiteshi esiphakathi kwalezi zindlela ezimbili ngeke sihlangane lapho sisebenza. Uma ungakwazi ukufeza ukuzinza kobuchwepheshe futhi uthole iphuzu lokulinganisela ezindleko, uhlelo lwe-Zigbee+Wifi lungaba ukukhetha okuhle Yiqiniso, kunzima ukusho ukuthi ngabe inqubo ye-Thread izozidla ngqo zombili lezi zindinganiso.

Isiphetho

Phakathi kweZigbee neWifi, akekho ongcono noma omubi kakhulu, futhi akekho onqobayo ngokuphelele, ukufaneleka kuphela. Ngokuthuthuka kobuchwepheshe, siyajabula futhi ukubona ukubambisana kwezinqubo zokuxhumana ezahlukahlukene emkhakheni wekhaya elihlakaniphile ukuxazulula izinkinga ezahlukahlukene emkhakheni wokuxhumana kwekhaya elihlakaniphile.
