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 ukuze 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...

I-WLAN ingachazwa kokubili ngomqondo obanzi nangomqondo omncane: Ngokombono omncane, sichaza futhi sihlaziye i-WLAN ngazo zombili izinzwa ezibanzi neziwumngcingo.Ngomqondo obanzi, i-WLAN iyinethiwekhi eyenziwe ngokufaka enye noma yonke imidiya yokudlulisa ye-LAN enezintambo ngamaza omsakazo, njenge-infrared, l...
