Ngokuhlanganisa ikhaya elixhunyiwe, i-Wi-Fi ibonakala njengento etholakala yonke indawo. Kuhle ukuba nazo ngokumataniswa kwe-Wi-Fi okuvikelekile. Lokho kungahamba kalula nerutha yakho yasekhaya ekhona futhi awudingi ukuthenga ihabhu elihlakaniphile elihlukile ukuze wengeze amadivayisi kulo.

Kodwa i-Wi-Fi nayo inemikhawulo yayo. Amadivayisi asebenza ku-Wi-Fi kuphela adinga ukushajwa njalo. Cabanga ngamakhompyutha aphathekayo, ama-smartphone, kanye nezipikha ezihlakaniphile. Ngaphandle kwalokho, azikwazi ukuzizitholela futhi kufanele ufake ngokwakho iphasiwedi yedivayisi entsha ye-Wi-Fi. Uma ngesizathu esithile isivinini se-inthanethi siphansi, singaguqula konke okwenziwa ekhaya okuhlakaniphile kube yiphupho elibi.

Ake sihlole izinzuzo nezingozi ezihlobene nokusebenzisa i-Zigbee noma i-Wi-Fi. Ukwazi lo mehluko kubalulekile njengoba kungaba nomthelela omkhulu ezinqumweni zakho zokuthenga imikhiqizo ethile yasekhaya ehlakaniphile.

1. Ukusetshenziswa kwamandla

I-Zigbee ne-Wifi zombili ubuchwepheshe bokuxhumana obungenantambo obusekelwe kubhendi ye-2.4GHz. Ekhaya elihlakaniphile, ikakhulukazi ekuhlakanipheni kwendlu yonke, ukukhetha kwephrothokholi yokuxhumana kuthinta ngqo ubuqotho nokuzinza komkhiqizo.

Uma kuqhathaniswa, i-Wifi isetshenziselwa ukudluliswa kwesivinini esikhulu, njengokufinyelela ku-inthanethi okungenantambo; I-Zigbee yakhelwe ukuthunyelwa kwezinga eliphansi, njengokusebenzelana phakathi kwezinto ezimbili ezihlakaniphile.

Nokho, lobu buchwepheshe bubili busekelwe kumazinga ahlukene angenantambo: I-Zigbee isekelwe ku-IEEE802.15.4, kuyilapho i-Wifi isekelwe ku-IEEE802.11.

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

Ngakho-ke, ekuxhumaneni kwekhaya elihlakaniphile, ukusetshenziswa kwamandla okuphansi kuyathandwa kakhulu, ngoba imikhiqizo efana nama-thermostats, adinga ukuqhutshwa amabhethri kuphela, ukuklama kokusetshenziswa kwamandla kubaluleke kakhulu. Ngaphezu kwalokho, i-Zigbee inenzuzo esobala uma iqhathaniswa ne-Wifi, inani lamanodi enethiwekhi liphezulu njenge-65,000; I-Wifi inama-50 kuphela. I-Zigbee ingama-millisecond angu-30, i-Wifi iyimizuzwana emi-3. Ngakho-ke, ingabe uyazi ukuthi kungani iningi labathengisi basekhaya abahlakaniphile njenge-Zigbee, futhi vele i-Zigbee iqhudelana nezinto ezifana ne-Thread ne-Z-Wave.

2. Ukuhlalisana

Njengoba i-Zigbee ne-Wifi inobuhle nobubi bayo, ingabe ingasetshenziswa ndawonye? Kufana nemithetho ye-CAN ne-LIN ezimotweni, ngayinye isebenzela uhlelo oluhlukile.

Kuyenzeka ngokwethiyori, futhi ukuhambisana kufanele kufundwe ngaphezu kokucatshangelwa kwezindleko. Ngoba womabili amazinga akubhendi ye-2.4ghz, angaphazamisana lapho esetshenziswa ndawonye.

Ngakho-ke, uma ufuna ukusebenzisa i-Zigbee ne-Wifi ngesikhathi esisodwa, udinga ukwenza umsebenzi omuhle ekuhlelweni kwesiteshi ukuze uqinisekise ukuthi isiteshi esiphakathi kwamaphrothokholi amabili ngeke sidlulelane lapho zisebenza. Uma ungakwazi ukuzuza ukuzinza kobuchwepheshe futhi uthole iphuzu lebhalansi ngezindleko, isikimu se-Zigbee+Wifi singase sibe inketho enhle Yebo, kunzima ukusho ukuthi ingabe iphrothokholi yochungechunge izodla kokubili la mazinga ngokuqondile.

Isiphetho

Phakathi kwe-Zigbee ne-Wifi, akekho ongcono noma omubi kakhulu, futhi akekho owinile ngokuphelele, ukufaneleka kuphela. Ngokuthuthukiswa kobuchwepheshe, siyajabula futhi ukubona ukusebenzisana kwezivumelwano ezihlukahlukene zokuxhumana emkhakheni we-smart home ukuxazulula izinkinga ezihlukahlukene emkhakheni wokuxhumana kwasekhaya okuhlakaniphile.
