Isingeniso kwi-Wi-Fi Inethiwekhi engenazintambo

I-Wi-Fi iye yavela njengeyona ndlela inqwenelekayo yenethiwekhi ye- wireless protocol yekhulu lama-21. Nangona ezinye iiprotokholi ezingenazintambo zisebenza kangcono kwiimeko ezithile, i-Wi-Fi iteknoloji inamandla amaninzi amanethiwekhi asekhaya, amaninzi amanxibelelwano ommandla wengingqi kunye namanethiwekhi asekuhlaleni .

Abanye abantu bayabhala iindidi zonxibelelwano ezingenazintambo njenge "Wi-Fi" xa ngokwenene i-Wi-Fi ingomnye wezobuchwepheshe obungenazintambo. Khangela - Ukhokelo kwiiNkqubo zoNxibelelwano lweN Wireless .

Imbali kunye neentlobo ze-Wi-Fi

Ngama-1980, iteknoloji eyenzelwe iirejistri zemali ezingenazintambo ezibizwa ngokuba yi- WaveLAN yaphuhliswa kwaye yabelwana kunye neCandelo loMbane kunye neZijineli zeeNjineli (IEEE) iqela elijongene nemigangatho yokunxibelelana, eyaziwayo njengekomiti 802. Le teknoloji yaphuhliswa phakathi kwee-1990 ukuya kwile komiti epapashwe umgangatho 802.11 ngo-1997.

Ifom yo kuqala ye-Wi-Fi ukususela kumgangatho we-1997 uxhaswe kuphela no-2 Mbps kuphela . Le teknoloji yayingaziwa ngokusemthethweni ngokuthi "i-Wi-Fi" ukususela ekuqaleni; eli qela lenziwe iminyaka embalwa nje ngokuba ukuthanda kwayo kwanda. Iqela lemigangatho yoshishino liye laqhubeka liguqukela umgangatho ukususela oko, ukuvelisa intsapho yeenguqulelo ezintsha ze-Wi-Fi ezibizwa ngokuba yi-802.11b, 802.11g, 802.11n, 802.11ac, kunye njalo. Inye yale miqathango enxulumene nayo inokunxibelelana omnye nomnye, nangona iinguqulelo ezitsha zenza umsebenzi olungcono kunye nezinye iimpawu.

Iimodeli ze-Wi-Fi Network Operation

I-Wi-Fi Hardware

Ii- routers ezingenasiphelo zesebhanti eziqhelekileyo ezisetyenziselwa kumanethiwekhi asekhaya (kunye neminye imisebenzi) njengeendawo zokufikelela kwi-Wi-Fi. Ngokufanayo, iindawo zokuhlala ze-Wi-Fi zoluntu zisebenzisa enye indawo okanye amanqaku afinyelelo okufakela ngaphakathi kwendawo yokujonga.

Ii-radios ezincinci ze-Wi-Fi kunye ne-antenna zifakwe ngaphakathi kwee-smartphone, iiptops, iiprinta, kunye nabathengi abaninzi bezinto ezibavumela ukuba basebenze njengabaxhasi bexhumo. Amanqaku okufikelela afakwe ngamagama enethiwekhi abathengi abanokuyifumana xa beskena ummandla ngamanethiwekhi atholakalayo.

I-Wi-Fi Hotspots

I-Hotspots yintlobo yesiseko senethiwekhi yendlela eyenzelwe ukufikelela kwi-intanethi okanye kwi-intanethi. Amanqaku amaninzi okufikelela kwi-hotspot basebenzisa iipakethi zee-software ezizodwa zokulawula ukubhaliselwa komsebenzisi nokunciphisa ukufikelela kwi-Intanethi ngokufanelekileyo.

Iiprotokholi zeeNethiwekhi ze-Wi-Fi

I-Wi-Fi inomgaqo-nkqubo wokuqhagamshela unxibelelwano wedatha osebenza ngaphaya kweyiphi na idibaniselwano yeempawu ezahlukeneyo kamva (PHY). Uluhlu lweenkcukacha luxhasa uxhaso olukhethekileyo lweMedia Access Control (MAC) olisebenzisa ubuchule bokuphepha (ukubizwa ngeCandelo leSense Multiple Access) kunye ne- CSMA / CA ukukunceda ukuphatha abaxumi abaninzi kwinethiwekhi yokuthetha ngokukhawuleza.

I-Wi-Fi isekela imbono yeziteshi ezifana nezo zethelevishini. Iseshoni ngasinye se-Wi-Fi isebenzisa ibanga elithile elithile kwiimpawu zamanqaku amakhulu (2.4 GHz okanye 5 GHz). Oku kuvumela amanxibelelanisi asekuhlaleni ukuba axhumane ngaphandle kokuphazamisana. Iiprotokholi ze-Wi-Fi zongeza uvavanyo lomgangatho wesignal phakathi kweefowuni ezimbini kwaye ulungelelanise isantya soqhagamshelwano lwezinga lolwazi xa kufuneka ukuba ukwandise ukuthembeka. I-logical protocol efunekayo ifakwe kwi- firmware ekhethekileyo efakwe ngaphambili ngumenzi.

Imiba eqhelekileyo enee-Wi-Fi Networks

Akukho teknoloji epheleleyo, kwaye i-Wi-Fi inesabelo sayo semida. Imiba eqhelekileyo abantu abajongene nayo neenethwekhi ze-Wi-Fi zibandakanya:

• Ukhuseleko - Intengiso yeenethiwekhi ezithunyelwa kwiinqununu ze-Wi-Fi zidlula emoyeni ovulekile ukuze zenzeke ukuba zixhomeke kubantu abangazimbi. Zininzi iintlobo zeteknoloji yezokhuseleko zongezwe kwi-Wi-Fi kule minyaka ukunceda ukulungisa le ngxaki, nangona abanye bebasebenza bhetele kunabanye. Okungakumbi - Isingeniso kwi-Wi-Fi Network Security
• Ukukhathazeka kwezeMpilo - Abanye abantu bathi ukubonakaliswa ngokubanzi kwiimpawu zomsakazo ezingenazintambo ezifana nalabo abavela kwiinkonzo ze-Wi-Fi zibangelwa intloko, isisongulu kunye nezinye izinto eziphathekayo. Uninzi lweengcaphephe zoshishino luqinisekisa uluntu ukuba i-Wi-Fi iphephile, kodwa ukuphikisana kuyaqhubeka njengamabango ngenye indlela okanye enye inzima ukubonisa. Okunye - Ukunxibelelana ngeN Wireless kunye neMpilo Yakho
• Uluhlu lwesalathisi - Inethiwekhi eyinqobo ye-Wi-Fi kunye neendawo zokufikelela ezingenazintambo kufinyelela kwiindawo ezininzi kuphela ngamanci ambalwa (100m okanye ngaphantsi) kunoma iyiphi na indlela. Ukwandisa uluhlu lwenethiwekhi ye-Wi-Fi kufuna ukuba kufakwe amanqaku afanelekileyo okufikelela ukuxubana nomnye, okuba kubiza kwaye kunzima ukuxhaswa, ngakumbi ngaphandle. Njengoko kunye nezinye iiprotokholi ezingenazintambo, ukuphazamiseka kwesignali (ukusuka kwezinye iifowuni ezingenantambo, okanye kwizinto eziphazamiseka ngokomzimba ezifana neendonga) kunokunciphisa uluhlu olufanelekileyo lwe-Wi-Fi kunye nokuthembeka kwayo yonke.
