Sonke siyazi ukuthi ku-LAN efanayo, ukuxhumeka kwehabhu kuzodala isizinda sokungqubuzana. Ngenkathi ingaphansi koshintsho, isizinda sokungqubuzana singaxazululwa, kuzoba nesizinda sokusakaza. Ukuze uxazulule lesi sizinda sokusakaza, kuyadingeka ukwethula amarutha ukuze ahlukanise ama-LAN ahlukene abe...

Enqubweni yokudlulisa inethiwekhi, uma wonke amahabhu asetshenziswa. Kuqinisekile ukuthi ohlelweni lokudlulisela, ngenxa yokuthi amasignali amaningi kakhulu adinga ukusakazwa, isizinda sokungqubuzana sizokwenziwa. Ngalesi sikhathi, ukuxhumana phakathi kwamasignali kuzophazamiseka kakhulu, futhi amadivaysi ku-s...

Iyini i-LAN? I-LAN isho Inethiwekhi Yendawo Yasendaweni. I-LAN imele isizinda sokusakaza, okusho ukuthi wonke amalungu e-LAN azothola amaphakethe okusakaza athunyelwa yinoma yiliphi ilungu. Amalungu e-LAN angakhuluma wodwa futhi angakwazi ukumisa izindlela zawo zokuthi amakhompyutha avela kubasebenzisi abahlukene akhulume nomuntu ngamunye...

Isendlalelo sesixhumanisi sedatha se-WLAN sisetshenziswa njengesendlalelo esiyinhloko sokudluliswa kwedatha. Ukuze uqonde i-WLAN, udinga futhi ukuyazi ngokuningiliziwe. Ngezincazelo ezilandelayo: Kumthetho olandelwayo we-IEEE 802.11, isisekelo saso se-MAC siqukethe izindlela zokufinyelela kwabezindaba ze-DCF ne-PCF: Incazelo ye-DCF: Sabalalisa...

I-PHY, isendlalelo esibonakalayo se-IEEE 802.11, inomlando olandelayo wokuthuthukiswa kobuchwepheshe kanye namazinga obuchwepheshe: IEEE 802 (1997) Ubuchwepheshe bemodulation: ukudluliselwa kwe-infrared ye-FHSS ne-DSSS Operating frequency band: esebenza ku-2.4GHz frequency band (2.42.4835GHz, 83.5MHZ isiyonke...

Kunamabizo amaningi abandakanyeka ku-WLAN. Uma udinga ukuqonda ngokujulile amaphuzu olwazi e-WLAN, udinga ukwenza incazelo egcwele yobungcweti yephuzu ngalinye lolwazi ukuze uqonde lokhu okuqukethwe kalula kakhudlwana esikhathini esizayo. Isiteshi (i-STA, ngamafuphi). 1). Isiteshi (iphuzu), al...
