Ukuze udibanise ikhaya eliqhagamshelweyo, i-Wi-Fi ibonwa njengokhetho olufumaneka kuyo yonke indawo. Kulungile ukuba nazo zinomgca we-Wi-Fi okhuselekileyo. Oko kunokuhambelana ne-router yakho yasekhaya ekhoyo kwaye akufuneki uthenge i-smart hub eyahlukileyo ukuze wongeze izixhobo kuyo.

Kodwa i-Wi-Fi nayo inemida yayo. Izixhobo ezisebenza kwi-Wi-Fi kuphela zifuna ukutshajwa rhoqo. Cinga ngeelaptops, ii-smartphones, kwanezithethi ezikrelekrele. Ngaphandle koko, azikwazi ukuzifumana kwaye kufuneka ufake igama eliyimfihlo ngesandla kwisixhobo ngasinye esitsha se-Wi-Fi. Ukuba ngesizathu esithile isantya se-intanethi siphantsi, sinokuguqula lonke amava akho ekhaya elikrelekrele abe yiphupha elibi.

Makhe sihlolisise izinto ezilungileyo nezingalunganga zokusebenzisa iZigbee okanye iWi-Fi. Ukwazi la mahluko kubalulekile kuba kunokuphembelela kakhulu izigqibo zakho zokuthenga iimveliso ezithile zekhaya ezikrelekrele.

1. Ukusetyenziswa kombane

I-Zigbee kunye ne-Wifi zombini ziiteknoloji zonxibelelwano ezingenazingcingo ezisekelwe kwibhendi ye-2.4GHz. Kwikhaya elikrelekrele, ingakumbi kwi-intelligence yendlu yonke, ukhetho lweprotocol yonxibelelwano luchaphazela ngokuthe ngqo ukuthembeka kunye nokuzinza kwemveliso.

Ngokuthelekiswa, iWifi isetyenziselwa uthumelo olukhawulezayo, njengokufikelela kwi-intanethi engenazingcingo; iZigbee yenzelwe uthumelo oluphantsi, njengokunxibelelana kwezinto ezimbini ezikrelekrele.

Nangona kunjalo, ezi teknoloji zimbini zisekelwe kwimigangatho eyahlukeneyo engenazingcingo: iZigbee isekelwe kwi-IEEE802.15.4, ngelixa iWifi isekelwe kwi-IEEE802.11.

Umahluko kukuba iZigbee, nangona izinga lokudlulisela liphantsi, elona liphezulu yi-250kbps kuphela, kodwa ukusetyenziswa kwamandla yi-5mA kuphela; Nangona iWifi inezinga lokudlulisela eliphezulu, i-802.11b, umzekelo, inokufikelela kwi-11Mbps, kodwa ukusetyenziswa kwamandla yi-10-50mA.

Ngoko ke, kunxibelelwano lwekhaya elikrelekrele, ukusetyenziswa kwamandla aphantsi ngokucacileyo kuyathandwa kakhulu, kuba iimveliso ezifana nee-thermostats, ekufuneka ziqhutywe ziibhetri zodwa, uyilo lokusetyenziswa kwamandla lubaluleke kakhulu. Ukongeza, iZigbee inenzuzo ecacileyo xa ithelekiswa neWifi, inani lee-nodes zenethiwekhi liphezulu njenge-65,000; iWifi yi-50 kuphela. IZigbee yi-30 milliseconds, iWifi yi-3 seconds. Ngoko ke, uyazi ukuba kutheni uninzi lwabathengisi bezindlu ezikrelekrele bethanda iZigbee, kwaye ewe iZigbee ikhuphisana nezinto ezifana neThread kunye ne-Z-Wave.

2. Ukuhlalisana kunye

Ekubeni iZigbee kunye neWifi zinezibonelelo kunye neengxaki zazo, ngaba zingasetyenziswa kunye? Kufana nemigaqo yeCAN kunye neLIN ezimotweni, nganye isebenzela inkqubo eyahlukileyo.

Ngokwethiyori inokwenzeka, kwaye ukuhambelana kuyafaneleka ukufundwa ukongeza kwiindleko. Ngenxa yokuba zombini ezi migangatho zikwibhendi ye-2.4ghz, zinokuphazamisana xa zisetyenziswa kunye.

Ngoko ke, ukuba ufuna ukusebenzisa iZigbee kunye neWifi ngaxeshanye, kufuneka wenze umsebenzi olungileyo ekulungiseleleni itshaneli ukuqinisekisa ukuba itshaneli phakathi kwezi protocol zimbini ayizukudityaniswa xa zisebenza. Ukuba unokufikelela kuzinzo lobuchwephesha kwaye ufumane ibhalansi kwixabiso, inkqubo yeZigbee+Wifi inokuba lukhetho olufanelekileyo Kakade ke, kunzima ukutsho ukuba iprotocol yeThread iya kuzitya zombini ezi migangatho ngokuthe ngqo.

Isiphelo

Phakathi kweZigbee neWifi, akukho mntu ungcono okanye mbi, kwaye akukho mntu uphumeleleyo ngokupheleleyo, kuphela kukufaneleka. Ngophuhliso lwetekhnoloji, sonwabile nokubona intsebenziswano yeenkqubo ezahlukeneyo zonxibelelwano kwicandelo lekhaya elikrelekrele ukusombulula iingxaki ezahlukeneyo kwicandelo lonxibelelwano lwekhaya elikrelekrele.
