LAN opanda waya Tanthauzo ndi Zitsanzo
Malo osungirako opanda waya (WLAN) amapereka mauthenga osayendetsa opanda intaneti pa maulendo afupipafupi pogwiritsira ntchito mailesi kapena mauthenga apachilendo mmalo mwazithunzi zamakono. WLAN ndi mtundu wa intaneti (LAN) .
WLAN akhoza kumangidwa pogwiritsa ntchito njira zosiyanasiyana zamakina opanda waya, makamaka Wi-Fi kapena Bluetooth .
Chitetezo cha pa Intaneti chikhalabe chofunikira kwa WLAN. Otsatsa opanda waya nthawi zambiri ayenera kukhala ndi umboni wotsimikizika (ndondomeko yotchedwa kutsimikiziridwa ) polowa nawo LAN opanda waya. Zipangizo zamakono monga WPA zimakweza mlingo wa chitetezo pazitsulo zopanda mauthenga kuti zisagwirizane ndi zokhudzana ndi magetsi.
WLAN Pros ndi Cons
Malo opanda waya a m'dera lanu ali ndi ubwino wake, koma sitiyenera kunyalanyaza zofookazo:
Zotsatira:
- Zida zambiri zimathandizidwa
- N'zosavuta kukhazikitsa WLAN, makamaka poyerekeza ndi kukhazikitsa zingwe zamagetsi
- Kufikira WLAN ndi kosavuta kuposa LAN yowongoka chifukwa kutalika kwa utali si chinthu
- Ma WLAN amavomerezedwa ngakhale pamene ali kutali ndi bizinesi kapena nyumba, monga m'malo ammudzi
Wotsatsa:
- Ziri zovuta kudodometsa WLAN, chifukwa chake kufotokozera ndi kofunikira
- Kusokoneza mafoni opanda zingwe kumatha kugwedeza liwiro ndi kukhazikika kwa intaneti opanda waya
- Zida zam'manja zopanda waya, monga ofunikiranso, zimayenera kuti zowonjezera makina opanda waya
Zida za WLAN
WLAN akhoza kukhala ndi zipangizo zingapo mpaka zana limodzi kapena kuposerapo. Komabe, makina opanda waya akukhala ovuta kwambiri kuyendetsa pamene chiwerengero cha zipangizo chikuwonjezeka.
Ma LAN opanda waya akhoza kukhala ndi mitundu yosiyanasiyana yamagetsi, kuphatikizapo:
- mafoni a m'manja
- laptop ndi tablet kompyuta
- makanema a ma intaneti
- masewera a masewera
- chipangizo china chilichonse chothandizira pa intaneti
WLAN Hardware ndi Ma Connections
Kulumikizana kwa WLAN kumagwiritsa ntchito makina opanga mauthenga a pawailesi ndi olandila opangidwa ndi makina osakaniza. Mapulogalamu opanda zingwe samafuna zipangizo, koma zida zingapo zapadera (komanso omwe ali ndi ma radio awo ndi mapulogalamu obvomerezeka) amagwiritsidwa ntchito kuti amange.
Mwachitsanzo, ma Wi-Fi amtundu wamtunduwu akhoza kumangidwa mwa njira ziwiri kapena ziwiri.
Mafilimu a Wifi-Wac-hoc WLAN amakhala ndi mgwirizano wapamtima pakati pa makasitomala omwe alibe zida zogwirira ntchito zomwe zilipo. Mapulogalamu apamalonda amtundu angakhale othandiza kupanga malumikizano a kanthaŵi kochepa, koma samawathandiza kuthana ndi zipangizo zingapo ndipo akhoza kuwonetsa zoopsa za chitetezo.
Njira yowonongeka ya Wi-Fi WLAN, kumbali ina, imagwiritsa ntchito chipangizo choyambira chotchedwa wireless access point (AP) chomwe makasitomala onse amagwirizanako. M'maseu apanyumba, mawotchi opanda waya opanda ntchito akugwira ntchito ya AP kuphatikizapo kuwapatsa WLAN kuti apeze intaneti. Ma APS ambiri angagwiritsidwe ntchito palimodzi ndikugwirizanitsa ma WLAN angapo kukhala wamkulu.
Ma LAN ena opanda waya alipo kuti athe kuwonjezera ma intaneti omwe alipo. Mtundu uwu wa WLAN umangidwa ndi kuyika malo othawira pamphepete mwa makina owongolera ndi kukhazikitsa AP kuti agwire ntchito yokonzera . Otsatsa amalankhulana ndi malo ogwiritsira ntchito pazitsulo zopanda waya ndipo akhoza kufika pa intaneti ya Ethernet kudutsa kugwirizana kwa mlatho wa AP.
WLAN vs. WWAN
Mafoni amagwiritsira ntchito mafoni a m'manja omwe amalumikizana pa maulendo ataliatali, mtundu wotchedwa wireless wide area networks (WWAN). Chomwe chimasiyanitsa maukonde a m'deralo kuchokera pa intaneti ndizojambula zomwe amagwiritsa ntchito pamodzi ndi malire ovuta pa mtunda ndi malo.
Malo ochezera a m'deralo amadziwika ndi nyumba kapena malo omwe anthu amalowetsa , pozungulira mazana kapena masentimita mapazi. Malo amtundu wautali amaphimba mizinda kapena madera, akuyenda maulendo angapo.
