Izincazelo ze-LAN ezingenantambo kanye nezibonelo
Inethiwekhi yendawo engenazintambo (WLAN) inikeza ukuxhumana kwenethiwekhi okungenawaya ngaphandle kwamadeshi amancane usebenzisa amasaka omsakazo noma we-infrared kunokuba iklabhu yenethiwekhi yendabuko. I-WLAN uhlobo lwenethiwekhi yendawo yendawo (i-LAN) .
I-WLAN ingakhiwa ngokusebenzisa noma iyiphi yezinhlelo eziningana zezintambo zenethiwekhi ezingenantambo, ikakhulukazi noma i- Wi-Fi noma i- Bluetooth .
Ukuphepha kwenethiwekhi kuyisimo esibalulekile kuma-WLAN. Amakhasimende angenazintambo ngokuvamile kumele abe nokuqinisekiswa kobunikazi bawo (inqubo ebizwa ngokuthi ukuqinisekiswa ) uma ujoyina i-LAN engenantambo. Ubuchwepheshe obufana ne- WPA buphakamisa izinga lokuvikeleka kumanethiwekhi angenantambo ukuze alwe namanethiwekhi wendabuko wambo.
I-WLAN Pros ne-Cons
Amanethiwekhi wendawo angenazintambo anezinzuzo zawo, kodwa akufanele sishaye indiva ukuwa:
Izinzuzo:
- Inani elikhulu lamadivayisi asekelwa
- Kulula ukusetha i-WLAN, ikakhulu uma kuqhathaniswa nokubeka izintambo kumanethiwekhi wensimbi
- Ukufinyelela ku-WLAN kulula kune-LAN enezintambo kusukela ubude bekhebula akuyona into ebalulekile
- Ama-WLAN ajwayelekile ngisho nalapho engekho ebhizinisini noma ekhaya, njengasezindaweni zomphakathi
Umthengi:
- Kulula ukushaya i-WLAN, ngakho-ke ukubethela kuyadingeka
- Ukuphazamiseka okungenantambo kungaphazamisa ijubane nokuzinza kwenethiwekhi engenantambo
- Amadivaysi angenantambo angaphezulu, njengabaphindaphindiwe, adingeka ukwandisa inethiwekhi engenantambo
Amadivayisi we-WLAN
I-WLAN ingaqukatha njengamadivayisi ambalwa kuya kwekhulu namakhulu. Kodwa-ke, amanethiwekhi angenantambo ayanzima kakhulu ukuphatha njengoba inani lamadivayisi landa.
Ama-LAN angenantambo angaqukatha izinhlobo eziningi zamadivayisi, kufaka phakathi:
- umakhalekhukhwini
- ama-laptop namathebulethi we-tablet
- izinhlelo zomsindo we-intanethi
- imidlalo yokudlala
- noma yimuphi omunye umsebenzi we-intanethi onikwe amandla we-intanethi noma idivayisi
I-WLAN Hardware ne-Connections
Ukuxhumeka kwe-WLAN kusebenza ngama-radio transmitters nama-receiver akhiwe kumadivayisi weklayenti. Amanethiwekhi angenantambo awadingi izintambo, kodwa amadivaysi amaningi ahlosekile (futhi anezikhangiso zawo nama-antenna alamukeli) avame ukusetshenziselwa ukwakha.
Amanethiwekhi wendawo we-Wi-Fi, isibonelo, angakhiwa nganoma iyiphi yezinhlobo ezimbili: isikhangiso noma ingqalasizinda .
Imodi ye-Wi-Fi ad-hoc I-WLAN ihlanganisa ukuxhumana kontanga nokuya phakathi kwamaklayenti angenazo izingxenye eziphathekayo zehadiwe ezihilelekile. Amanethiwekhi wendawo we-Ad-hoc angaba usizo ukwenza uxhumano lwesikhashana kwezinye izimo, kodwa azikali ukusekela okungaphezu kwamadivayisi ambalwa futhi angafaka nezingozi zokuphepha.
Imodi yengqalasizinda ye-Wi-Fi i-WLAN, ngakolunye uhlangothi, isebenzisa idivayisi ephakathi ebizwa ngokuthi i- wireless access point (AP) wonke amaklayenti axhuma kuwo. Ezingxenyeni zasemakhaya, ama-router angenayo wireless enza imisebenzi ye-AP plus ivumela iWLAN ukuthola ukufinyelela kwe-intanethi ekhaya. Ama-AP amaningi angakwazi ukungena phakathi noma ukuxhumeka ama-WLAN amaningi ibe yikhulu.
Amanye ama-LAN angenazintambo akhona ukuze anwebe inethiwekhi ekhona yocingo. Lolu hlobo lwe-WLAN lwakhiwe ngokufaka iphoyinti lokufinyelela enqenqemeni yenethiwekhi ethintekile futhi usethe i-AP ukuthi isebenze kumodi yokugodla . Amaklayenti axhumane nendawo yokufinyelela ngokusebenzisa isixhumanisi esingenantambo futhi angafinyelela kwinethiwekhi ye-Ethernet ngokusebenzisa uxhumano lwe-Bridge lwe-AP.
I-WLAN vs. WWAN
Amanethiwekhi weselula asekela amafoni ephathekayo axhumanisa amabanga amade, uhlobo lwama-network wendawo angama-wide (WWAN) okuthiwa yi-wireless wide. Okuhlukanisa inethiwekhi yendawo kusuka kunethiwekhi enkulu yizindlela zokusetshenziswa ezizisekelayo kanye nemingcele ethile embi ebangeni langasese kanye nendawo.
Inethiwekhi yendawo yendawo izithengisa izakhiwo noma izindawo zokuhlala zomphakathi , zihlanganisa amakhulu noma izinkulungwane zamamitha ayizinkulungwane. Amanethiwekhi omhlaba wonke ahlanganisa amadolobha noma izifundazwe, ahamba ngamamayela amaningi.
