Ukususela kwiWWII ukuya kwi-Wi-Fi yangoku
Indlela yokusabalalisa imbonakalo yokunxibelelana nge-wire isetyenziswa namhlanje kwi- Wi-Fi kunye namanye amanethiwekhi amanethiwekhi ukuze afumane ezi nzuzo zilandelayo:
- Ukunyaniseka okuphuculweyo - kunciphisa impembelelo yokungaphazamiseki okungenaxhala kwinqanaba lokunxibelelana
- Ukwandiswa kwamanqwanqwa-mbonakalo - ukuxhaphaza i-spectrum engabonakaliyo engenakucala ukuba isebenzise ngakumbi kwaye yabelane ngesantya-bhinqa phakathi kweendlela ezininzi
- Ukuphucula ukukhuseleko - umda wokuba abahlaseli bamkele ukuthunyelwa
Ingcamango ebalulekileyo emva kokusabalalisa i-spectrum kukuba ukwahlulelana unxibelelwano olungenazintambo kwi-set of related transmissions, thumela imiyalezo kwiinkalo ezahlukeneyo zee-rediyo, ngoko uqokelele uphinde uphinde uqoke umqondiso kwinqanaba lokufumana.
Kukho ubuchule obuhlukeneyo obukhoyo bokuphumeza umonakalo wokusabalalisa kwiintanethi ezingenazintambo. Iiprotokholi ze-Wi-Fi zisebenzisa i- frequency hopping (FHSS) kunye nokulandelana ngokuthe ngqo (DSSS).
Imbali yokuSasaza kweTeknoloji yeTeknoloji
Ukusabalalisa ubuchwepheshe be-spectrum buye lwaphuhliswa ekuqaleni ukuze kuphuculwe ukunyaniseka nokukhuselwa koonomathotholo, ngokukodwa kwiinkqubo zonxibelelwano zempi. Ngaphambi kwexesha leMfazwe Yehlabathi II, abantu abaninzi abadumileyo babandakanyeka kuphando olusenyakatho kwiimfono zokufakela izixhobo ezibandakanya i-spectrum, kuquka uNikola Tesla noHedy Lamarr. Ngaphambi kokuba i-Wi-Fi kunye neenethwekhi zeselula zaziwa, i-industry ye-telecommunications yaqala ukukhupha ezinye iinkqubo ezahlukeneyo zokusabalalisa i-spectrum ukususela kuma-1980.
