1. IEEE802.11b kunye ne-IEEE802.11g zombini zisetyenziswa kwi-2.4GHz band frequency. Makhe sichaze ezi prothokholi zimbini ngendlela eqhubekayo ukuze siqonde imigangatho yeeprothokholi ezahlukeneyo. IEEE 802.11b ngumgangatho wothungelwano lwengingqi olungenazingcingo. I-frequency carrier yayo yi-2.4GHz, kwaye...

Funda ngakumbi malunga ne-IEEE 802.11a kwiprotocol yeWiFi, eyiprotocol yokuqala yebhendi ye-5G. 1) Utoliko lweProtocol: IEEE 802.11a ngumgangatho ohlaziyiweyo we-802.11 kunye nomgangatho wayo wokuqala, owavunywa ngo-1999.

Kwi-IEEE802.11 protocol kwi-WiFi, inani elikhulu lemibuzo yedatha yenziwa, kwaye uphuhliso lwembali lushwankathelwa ngolu hlobo lulandelayo. Esi sishwankathelo silandelayo asilorekhodi elibanzi neneenkcukacha, kodwa yinkcazo yeeprothokholi ezisetyenziswa ngoku kwimarike. IEEE 802.11, isekwe kwi...

Ukusukela kwiMfazwe yeSibini yeHlabathi, unxibelelwano olungenazingcingo lunikwe ingqwalasela engakumbi ngenxa yesicelo somkhosi, esiphucule kakhulu imida yokuhanjiswa kolwazi kwimo engqongileyo. Ukusukela ngoko, unxibelelwano olungenazingcingo luyaphuhla, kodwa alunaluhlu olubanzi lwe ...

I-fiber optical yitshaneli eneentambo zokuhambisa imiqondiso ye-optical. Sibiza izibonakaliso zombane ezingafunekiyo kwitshaneli "ingxolo Ingxolo kwinkqubo yonxibelelwano igxininiswe kwisignali. Xa kungekho mqondiso wothumelo, kukho ingxolo kwindlela yonxibelelwano. &#...

Ijelo sisixhobo sonxibelelwano esidibanisa isiphelo sothumelo kunye nesiphelo sokufumana, kwaye umsebenzi walo kukuhambisa imiqondiso ukusuka kwisiphelo sothumelo ukuya kwisiphelo sokufumana. Ngokwamajelo osasazo ahlukeneyo, amajelo anokwahlulwa abe ngamacandelo amabini: itshaneli ezingenazingcingo kunye neengcingo ...
