I-Wireless LAN Inkcazo kunye nemizekelo
Inethiwekhi yommandla wengingqi engenazintambo (WLAN) inikeza unxibelelwano lwenethiwekhi ngaphandle kwentambo emfutshane ngokusebenzisa i-redio okanye uphawu lwe-infrared endaweni yesikhokelo somnatha wendabuko. I-WLAN luhlobo lomnatha wommandla wengingqi (LAN) .
I-WLAN ingakhiwa isebenzisa nayiphi na inkqubo ehlukeneyo yomnatha wee wireless, ngokuqhelekileyo i- Wi-Fi okanye i- Bluetooth .
Ukhuselo lwenethiwekhi luyinto ebalulekileyo kwi-WLAN. Abaxhasi abangenazintlu kufuneka baqinisekiswe ukuba bazisiwe (inkqubo ebizwa ngokuba yi- authentication ) xa bejoyina i-LAN engenazintambo. I-Technologies efana ne- WPA iphakamisa inqanaba lekhuseleko kumanethiwekhi angenawucingo ukuxhatshazwa kweenethiwekhi zomnxeba zendabuko.
I-WLAN Pros ne-Cons
Unxibelelwano lwamabala angaphandle lwangaphandle alukwazi ukuba luncedo, kodwa akufanele siwagxeke iziphazamiso:
Iinkonzo:
- Inani elikhulu lamacebo axhaswa
- Kulula ukumisa i-WLAN, ngakumbi xa kuthelekiswa nokubeka iintambo kwiintanethi ezicwangcisiweyo
- Ukufikelela kwi-WLAN kulula kunokuba i-LAN enekhenketho kuba ubude bekhebula abuyiyo into
- Ii-WLAN ziqhelekile nangona zingekho kwi-shishini okanye kwikhaya, njengemimandla kawonkewonke
Umgcini:
- Kulula ukukhawuleza i-WLAN, kungenxa yoko ukubethela kubalulekile
- Ukuphazamiseka kwentambo kungaphazamisa isantya nokuzinza kwenethiwekhi engenazintambo
- Ezinye iifowuni ezingenantambo, njengeziphindaphindiweyo, ziyadingeka ukwandisa inethiwekhi engenazintambo
Izixhobo zeWLAN
I-WLAN inokuqulatha nje ngeendlela ezimbalwa njengezixhobo ezimbini ukuya kwekhulu nangaphezulu. Nangona kunjalo, amanxibelelwano angenazintambo ayanzima kakhulu ukulawula njengoko inani lamadivayisi landa.
Ii-LAN ezingenazintlu zinokudibanisa iindidi ezininzi zezixhobo, kuquka:
- fowuni
- iikhomputha kunye neekhompyutha
- iinkqubo zomsindo wekhompyutha
- zokudlala imidlalo
- nayiphi na into eyenziwe nge-intanethi eyenzelwe amandla kwi-intanethi okanye kwisixhobo
I-WLAN Hardware kunye neNxibelelwano
Uxhumano lwe-WLAN lusebenza ngama-radio transmitters kunye nabamkeli abakhiweyo kwiinkqubo zabaxumi. Unxibelelwano olungenazintambo aludingi iimbambo, kodwa iinqununu eziliqela zeenjongo ezikhethekileyo (nazo ziphethe ii-radios zazo kunye nama-antenna awamkeleyo) ziqhelekileyo zisetyenziselwa ukwakha.
Umnxeba we-Wi-Fi wendawo, umzekelo, unokukwakhiwa kwiindlela ezimbini: i- ad-hoc okanye iziseko .
Imodi ye-Wi-Fi ye-hoc-hoc I-WLAN iquka ukunxulumana koontanga kunye noontanga phakathi kwabathengi abangenazo izixhobo ze-hardware eziphakathi ezibandakanyekayo. Amanethiwekhi asekuhlaleni angasiluncedo ukwenza udibaniso lwexeshana kwezinye iimeko, kodwa azinakude ukuxhasa ngaphezu kweefowuni ezimbalwa kwaye unokukunceda neengozi zokhuseleko.
Imoya yesikhokelo se-Wi-Fi i-WLAN, ngakolunye uhlangothi, isebenzisa isistim esisisiseko esibizwa ngokuba yindawo yokufikelela engena - wire (AP) ukuba bonke abathengi badibanise. Kwiintanethi zasekhaya, ii- routers zokuhamba ngee- wireless zenza imisebenzi ye-AP kunye nokunika amandla i-WLAN kwi-intanethi yokufikelela kwi-intanethi. Ii-AP ezininzi ziyakwazi ukudibanisa kwaye zidibanise ii-WLAN ezininzi zibe zikhulu.
Ezinye ii-LAN ezingenazintambo zikhoyo ukuze zenzele inethiwekhi yomnatha ekhoyo. Olu hlobo lwe-WLAN lwakhiwe ngokuhlanganisa indawo yokufikelela kumda womnatha weshoni kwaye usethe i-AP ukuba isebenze kwimodi yokubhinqa . Abaxhasi baqhagamshelana neendawo zokufikelela kwikhonkco elingenazintambo kwaye bangafikelela kwinethiwekhi ye-Ethernet ngokusebenzisa uxhumo lwe-bridge ye-AP.
WLAN vs WWAN
Amanethiwekhi eselula axhasa iifowuni zefowuni zixhuma kwiimitha ezide, uhlobo oluthiwa lunxibelelwano lwamabala amaninzi angenaselula angama-wire (WWAN). Yintoni eyahlula inethwekhi yendawo ukusuka kwinethiwekhi enkulu kukuba imodeli yokusetyenziswa axhasayo kunye nemida ethile embi kumgama omzimba kunye nommandla.
Inethwekhi yendawo yendawo ihlanganisa izakhiwo ngamnye okanye izikhundla zomphakathi , ziquka amakhulu okanye amawaka ezinyawo zesikwele. Amanethiwekhi ommandla amaninzi ahlamba izixeko okanye imimandla yelizwe, ehamba ngamamayela amaninzi.
