Yintoni i-LAN? I-LAN ithetha Uthungelwano lweNdawo yeNgingqi. I-LAN imele i-domain yosasazo, okuthetha ukuba onke amalungu e-LAN aya kufumana iipakethi zosasazo ezithunyelwa naliphi na ilungu. Amalungu e-LAN anokuthetha omnye nomnye kwaye anokuseta iindlela zawo zeekhompyuter ezisuka kubasebenzisi abahlukeneyo ukuba bathethe nomntu ngamnye o...

Umaleko wekhonkco lwedatha ye-WLAN isetyenziswa njengomaleko ophambili wokuhanjiswa kwedatha. Ukuze uqonde i-WLAN, kufuneka uyazi ngokweenkcukacha. Ngokusebenzisa ezi ngcaciso zilandelayo: Kwiprothokholi ye-IEEE 802.11, i-sublayer yayo ye-MAC iqulethe iindlela zokufikelela kwimidiya ye-DCF kunye ne-PCF: Intsingiselo ye-DCF: Ukusabalalisa...

I-PHY, umaleko womzimba we-IEEE 802.11, unembali elandelayo yophuhliso lwetekhnoloji kunye nemigangatho yobugcisa: IEEE 802 (1997) Itekhnoloji yokumodareyitha: ukuhanjiswa kwe-infrared ye-FHSS kunye ne-DSSS Ibhendi yokuqhutywa kwamaza: esebenza kwi-2.4GHz frequency band (2.42.4835GHz, 83.5MHZ iyonke...

Kukho izibizo ezininzi ezibandakanyekayo kwi-WLAN. Ukuba ufuna ukuqonda ngokunzulu amanqaku olwazi lwe-WLAN, kufuneka wenze inkcazo epheleleyo yobungcali kwinqanaba ngalinye lolwazi ukuze ukwazi ukuqonda lo mxholo ngokulula ngakumbi kwixesha elizayo. Isitishi (STA, ngokufutshane). 1). Isikhululo (inqaku), al...

I-WLAN inokuchazwa kuzo zombini ingqiqo ebanzi kunye nengqiqo emxinwa: Ukusuka kwimbono encinci, sichaza kwaye sihlalutye i-WLAN kwiimvakalelo ezibanzi kunye nezimxinwa. Ngengqiqo ebanzi, i-WLAN yinethiwekhi eyenziwe ngokutshintshela enye okanye yonke imidiya yosasazo ye-LAN enentambo ngamaza erediyo, anje nge-infrared, l...

I-Constellation yingcamango esisiseko kwimodyuli yedijithali. Xa sithumela imiqondiso yedijithali, ngokuqhelekileyo asithumeli u-0 okanye u-1 ngokuthe ngqo, kodwa kuqala senze iqela leempawu ze-0 kunye ne-1 (iibits) ngokomnye okanye ezininzi. Umzekelo, onke amasuntswana amabini enza iqela, oko kukuthi, 00, 01, 10, kunye no-11. Zine iimo ...
