Kupanga Makhalidwe Osiyanasiyana a WiFi Protocol
WiFi ndi teknoloji yopanda waya yopambana kwa ma intaneti. N'zovuta kulingalira foni yamakono, pulogalamu yamapiritsi PC, router, repeater kapena kompyuta ina yamakono kapena kompyuta yanu popanda WiFi. Tikuwongolera ma waya Ethernet pang'onopang'ono.
Chimodzi mwa zinthu zoyamba zomwe timatsimikizira pazinthu zomwe tisanayambe kugula chipangizo cha m'manja ndi ngati zimathandizira WiFi chifukwa imatsegula chitseko ku malo, masewera, zosintha, ndi kulankhulana, zinthu zomwe popanda chipangizochi chikanakhala chopanda phindu. Koma kodi ndikwanira kungoyang'ana WiFi? Kuti mudziwe zambiri zokhudza WiFi, zoperewera, ndi zopindulitsa, werengani ndondomekoyi .
Nthaŵi zambiri, inde, koma pankhani ya hardware yapadera monga obwereza ndi oyendetsa, ndi bwino kuyang'ana mawonekedwe a WiFi.
Kugwirizana pakati pa Miyezo ya WiFi
Malo ogwira ntchito omwe amapanga WiFi hotspot , monga router, ndi chipangizo chogwirizanitsa, akuyenera kukhala ndi machitidwe omwe amagwirizana kuti agwirizane ndi kupititsa patsogolo. Zimapambana m'zochitika zonse chifukwa pali kuvomerezana kumbuyo, koma vuto liri mu zoperewera. Mwachitsanzo, ngati muli ndi Samsung Galaxy yatsopano yomwe ikuthandizira ma Wiigi atsopano, okonzekera kufulumira gigabits pamphindi, koma ndikuyikulumikiza ku intaneti yomwe ili ndi malo ogwiritsira ntchito omwe akuthandizira WiFi yakale komanso yochepa foni yamakono siidzakhala yabwino kuposa foni ina iliyonse ponena za kugwirizana kwachangu.
WiFi amagwira ntchito zosiyana-siyana - 2.4 GHz ndi 5 GHz. Wotsirizira amapereka zowonjezera zazikulu ndipo alibe wolumala, motero mofulumira kugwirizana, koma sali odalirika kwambiri kuposa poyamba. Ngati chipangizo chomwe chimagwira ntchito yoyamba kokha chikuyesa kugwirizana ndi zomwe zimagwira ntchito yachiwiri yokha, kugwirizana sikungapambane. Mwamwayi, zipangizo zamakono zamakono zimagwira ntchito limodzi ndi ma spectra onse.
Choncho, n'zotheka kuti muli ndi ma hardware abwino ndi mapulogalamu ofulumira, koma omwe ndi ofooka komanso otsika kwambiri chifukwa cha kusagwirizana kwina kwinakwake, ngati mungasinthe machitidwe ena, kapena kusintha kokha adapita kapena chipangizo.
Mafilimu a WiFi ndi Zomwe Amafotokoza
WiFi imatchedwa kuti 802.11 protocol . Miyezo yosiyana yomwe idapitilira zaka zonsezi ikuyimiridwa ndi makalata ochepa ngati chikwama. Nazi ena:
802.11 - Buku loyamba limene linayambika mu 1977. Sichigwiritsidwanso ntchito. Zimagwira pa 2.4 GHz.
802.11a - Ntchito pa 5GHz. Mofulumira 54 Mbps. Zimakhala zovuta kudutsa zopinga, choncho zimakhala zovuta.
802.11b - Zimagwira ntchito zodalirika kwambiri 2.4Ghz ndipo zimapereka mpaka 11 Mbps. Bukuli linabwera pamene WiFi ikuphulika popititsa patsogolo.
802.11g - Anatulutsidwa mu 2003. Komabe, amagwira ntchito pa 2.4GHz odalirika, koma adawonjezeka pawindo lalikulu mpaka 54 Mbps. Ndizofunikira kwambiri m'mawonekedwe oyambirira a WiFi kusanachitike kotsatira kwakukulu kuti mubwere mu 2009. Zida zambiri zimagwiritsabe ntchitoyi bwinobwino chifukwa ndi zotchipa kuti zitheke.
802.11n - Kusintha kwa makina opanga mauthenga ndi mauthenga opatsirana kumathamanga msanga mpaka 600 Mbps, ndi zina zabwino.
802.11ac - Kupititsa patsogolo miyezo yoyamba, kugwiritsa ntchito bwino 5Ghz ma spectrum, ndi kupereka mofulumira bwino kuposa 1 Gbps.
802.11ax - Izi zimapangitsa 802.11ac kuonjezera liwiro mobwerezabwereza, theoretically kufika 10 Gbps. Zimapangitsanso kuti ma WLAN azikhala bwino.
