I-FHSS, itekhnoloji ye-frequency hopping spread spectrum, phantsi kwemeko yongqamaniso kunye nexesha elinye, yamkela imiqondiso ehanjiswa ngabathwali bebhendi emxinwa yohlobo oluthile (olu hlobo luthile lune-frequency ethile, njl. njl.) kuzo zombini iziphelo. Kumamkeli ngaphandle kohlobo oluthile, i-hop...

I-OFDM iye yacetywa kwi-IEEE802.11a. Ngokusekwe kule ndlela yokumodareyitha, kufuneka sazi ukuba yintoni i-OFDM ukuqonda iiprothokholi ezahlukeneyo. Yintoni iOFDM? I-OFDM yitekhnoloji ekhethekileyo yokumodareyitha enezinto ezininzi. Le teknoloji ijolise ekwahluleni itshaneli ibe ngamajelo asezantsi e-orthogonal, kunye ...

Indlela yokubala izinga le-Wi-Fi 6? Okokuqala, qikelela ukusuka ekuqaleni ukuya ekupheleni: Izinga losulelo liya kuchaphazeleka linani lemijelo yendawo. Inani lamasuntswana othungelwano ngamnye anokuhambisa linani leebhithi ezinekhowudi kwi-subcarrier nganye. Okukhona uphezulu izinga lekhowudi, ngcono. Zingaphi ...

Okokuqala, makhe sifunde nge-IEEE 802.11ax. Kumfelandawonye we-WiFi, ibizwa ngokuba yi-WiFi 6, ekwabizwa ngokuba yinethiwekhi yendawo engenazingcingo engenazingcingo. Ngumgangatho wothungelwano lwengingqi olungenazingcingo. I-11ax ixhasa i-2.4GHz kunye ne-5GHz iibhendi, kwaye inokubuyela ngasemva iyahambelana neprotoco esetyenziswa ngokuqhelekileyo ...

I-802.11n kufuneka ichazwe ngokwahlukileyo. Okwangoku, imarike yesiqhelo isebenzisa le protocol yokuhanjiswa kweWiFi. I-802.11n yiprotocol esemgangathweni yothumelo olungenazingcingo. Yitekhnoloji yokwenza i-epoch-making. Inkangeleko yayo yenza ukuba izinga lothungelwano lwamacingo linyuke kakhulu. Ukuze kuphuculwe i...

Kukho iikhonsepthi ezininzi kunye neeprothokholi ezibandakanyekayo kwiinethiwekhi ezingenazingcingo. Ukuze ndinike wonke umntu umbono ongcono, ndiya kuchaza ulwahlulo. 1. Ngokuhambelana nenethiwekhi eyahlukeneyo, iinethiwekhi ezingenazingcingo zinokwahlulwa zibe: "i-WWAN" imele "inethiwekhi yendawo engenazingcingo. &...
