1. IEEE802.11b kanye ne-IEEE802.11g zombili zisetshenziswa kubhendi yefrikhwensi engu-2.4GHz. Ake sichaze lezi zimiso ezimbili ngendlela eqhubekayo ukuze siqonde izindinganiso zamaphrothokholi ahlukene. I-IEEE 802.11b indinganiso yamanethiwekhi endawo angenantambo. Imvamisa yenkampani yenethiwekhi ingu-2.4GHz, futhi...

Funda kabanzi mayelana ne-IEEE 802.11a kuphrothokholi ye-WiFi, okuyiphrothokholi yokuqala yebhendi ye-5G. 1) Ukuhumusha kwephrothokholi: I-IEEE 802.11a iyindinganiso ebuyekeziwe engu-802.11 nezinga layo lokuqala, elavunywa ngo-1999. Iphrothokholi ewumongo yezinga le-802.11a iyafana nezinga lokuqala, ...

Kuphrothokholi ye-IEEE802.11 ku-WiFi, inani elikhulu lemibuzo yedatha liyaqhutshwa, futhi ukuthuthukiswa komlando kufinyezwa ngale ndlela elandelayo. Isifinyezo esilandelayo akulona irekhodi eliphelele nelinemininingwane, kodwa incazelo yemithetho esetshenziswa njengamanje emakethe. I-IEEE 802.11, yasungulwa i...

Kusukela ngeMpi Yezwe Yesibili, ukuxhumana okungenantambo kuye kwanakwa kakhulu ngenxa yokusetshenziswa kwezempi, okuthuthukise kakhulu ukulinganiselwa kokudluliselwa kolwazi endaweni ezungezile. Kusukela lapho, ukuxhumana okungenantambo belokhu kuthuthuka, kepha akunalo uhlu olubanzi lwe ...

I-optical fiber iyishaneli enezintambo yokudlulisa amasignali okubona. Sibiza amasignali kagesi angafuneki esiteshini “umsindo Umsindo ohlelweni lokuxhumana ubekwe phezulu esignali. Uma ingekho isignali yokudlulisela, kunomsindo futhi ohlelweni lokuxhumana. &#...

Ishaneli iyisisetshenziswa sokuxhumana esixhuma isiphetho sokudlulisela kanye nesiphetho sokwamukela, futhi umsebenzi waso ukudlulisa amasignali ukusuka ekugcineni kokudlulisela kuya ekugcineni kokwamukela. Ngokusho kwemidiya ehlukene yokudlulisa, iziteshi zingahlukaniswa ngezigaba ezimbili: iziteshi ezingenantambo kanye nezintambo ...
