Isivinini sezintambo kanye nesivinini sangempela yizinkulungwane zamakhilomitha
Umkhawulokudonsa wokuphakama wama- 802.11b ongenazintambo yi-11 Mbps. Lena inombolo yokusebenza ekhangiswa kwimishini engu-802.11b ye-Wi-Fi , abantu abaningi abalingana nesivinini esilindelekile senethiwekhi. Kodwa-ke, leveli yokusebenza ayitholakali ngokusebenza ngoba ngenxa yokuxhumana kwenethiwekhi nezinye izici.
I-standard ejwayelekile ye-throughput-egcinwe isilinganiso sedatha-ye-uxhumano lwe-wireless engu-802.11b ngaphansi kwezimo ezihle zedatha lomsebenzisi wokugcina cishe ku-4 kuya ku-5 Mbps. Lelizinga lokusebenza liqala iklayenti elingenantambo eliseduze nesiteshi sesisekelo noma elinye iphuzu lokuxhumana. Ngenxa yobunzima bokubukeka kwe-Wi-Fi, ama-802.11b we-passput izinombolo ancipha njengoba iklayenti idlulela kude nesiteshini sesisekelo.
Umehluko Omkhulu Phakathi Kwezingqinamba Zangempela Nezikhombo 802.11b
Umehluko omkhulu phakathi kwamazinga e-theory futhi yangempela yedatha ka-802.11b ngokuyinhloko ngokuyinhloko ku-protocol ngaphezulu. I-Wi-Fi ikhiqiza inani elikhulu kakhulu lomgwaqo ukugcina uxhumano, ukuxhumanisa ukuthumela nokuvuma imiyalezo, nokugcina olunye ulwazi lombuso wangasese. I-Throughput nayo iyancipha uma ukuphazanyiswa ku-802.11b ububanzi besignali ye 2.4 GHz bukhona. Ukungaboni ngaso sonke isikhathi kubangele ukubuyiswa kwe-retransmissions ngenxa yenkohlakalo yedatha noma ukulahlekelwa kwepakethe.
Kuthiwani Ngezingu 22 Mbps 802.11b?
Imikhiqizo ye-Wi-Fi engu-802.11b ithi ixhasa ukuphakama kwe-22 Mbps. Abathengisi bakha lezi zinguquko zokuthengisa ezingu-802.11b ngokukhulisa ubuchwepheshe ngezindlela ezahlukahlukene ezingezansi. I-input yangempela yama-22 Mbps 802.11b amanethiwekhi ayiphindaphindi kabili yensiza ejwayelekile ye-802.11b, nakuba i-passput esezingeni elivamile lingakhuphuka cishe ku-6 kuya ku-7 Mbps.
Okubalulekile
Ngenkathi izibalo zezinga eliphezulu zedatha zingafinyeleleka ngezinye izikhathi, futhi izindlu ezimbalwa zingase zithuthukiswe ku-22 Mbps gear, izixhumanisi eziningi zenethiwekhi ekhaya ezingu-802.11b zivame ukugijima ku-2 kuya ku-3 Mbps. Lokhu kuyashesha kunezinye izinhlobo zokuxhumeka kwe- intanethi ekhaya kodwa ngokuya kancane kakhulu ijubane lokuxhumana kwenethiwekhi yanamuhla. Izinguqulo zamuva zalomthetho-protocol-802.11g, n, futhi ziphumelela ngokuphumelelayo.
Okokugcina, isivinini esibhekwayo senethiwekhi sinqunyelwe nje kuphela nge-bandwidth esitholakalayo kodwa futhi ngokususwa kwenethiwekhi .
