Kusuka ku-WWII kuya kwi-Wi-Fi yanamuhla
Indlela yokusabalalisa insalela yokuxhumana okungenantambo isebenza namuhla ku- Wi-Fi nakwamanye amanethiwekhi weselula ukuthola izinzuzo ezilandelayo:
- Ukuthembeka okuthuthukisiwe - kunciphise umthelela wokuphazamiseka okungenantambo kumzila wokuxhumana
- Ukwenyuka komkhawulokudonsa - kuxhaphaza i-spectrum engenazintambo ezengeziwe ukuze isebenzise kangcono futhi yabelane ngomkhawulokudonsa phakathi kweziteshi eziningi
- Ukuvikeleka okuthuthukisiwe - kunciphisa ikhono labahlaseli ukuvimbela ukuthunyelwa
Umqondo oyinhloko ngemuva kokusabalalisa i-spectrum ukuhlukanisa ukuxhumana okungaxhunyiwe ku-intanethi kuqoqo lokudluliselwa okuhlobene, thumela imiyalezo yonkana kuma-frequencies amaningi, bese uqoqa futhi uvuselele amasignali ohlangothini olutholayo.
Kukhona amasu amaningana ahlukene ekusebenziseni ukusabalalisa ama-wireless amanethiwekhi angenantambo. Ama-protocol ase-Wi-Fi asebenzisa kokubili ama-frequency hopping (FHSS) nokulandelana ngokuqondile (i-DSSS) ekusakazeni i-spectrum.
Umlando Wokusabalalisa I-Spectrum Technology
Ukusabalalisa ubuchwepheshe be-spectrum kwakhiwa ekuqaleni ukuze kuthuthukiswe ukuthembeka nokulondeka kokudluliselwa komsakazo, ngokuyinhloko kumahlelo ezokuxhumana ezempi. Ngaphambi nangesikhathi seMpi Yezwe II, abantu abaningi abadumile babebandakanyeka ekucwaningeni kwasekuqaleni mayelana nokuvame ukuqhubekela phambili izinhlelo zokusebenza ezihlanganisa ukusasazwa kukaNicola Tesla noHedy Lamarr. Ngaphambi kokuba kusetshenziswe i-Wi-Fi namanethiwekhi weselula, imboni yezokuxhumana yaqala ukukhipha ezinye izinhlelo ezihlukahlukene zokusabalalisa ama-spectrum kusukela ngawo-1980.
