Kuwoneka kwa mbiri yakale pa matekinoloje a Wi-Fi
802.11g ndi IEEE yapamwamba yamakina osakanikirana ndi matelefoni . Monga Mabaibulo ena a Wi-Fi , 802.11g (omwe nthawi zina amatchulidwa kuti "G") amathandiza mauthenga osakayika opanda magetsi (WLAN) pakati pa makompyuta, maulendo apakompyuta , ndi zipangizo zambiri zamagula.
G inavomerezedwa mu June 2003, ndipo idakhazikitsa malo oposa 802.11b ("B"), kenako potsirizira pake anasankhidwa ndi 802.11n ("N") ndi miyezo yatsopano.
Kodi Mwamsanga Ndili 802.11g?
Wi-Fi ya 802.11g imathandizira pawindo lapamwamba la bandwidth la 54 Mbps , moposa kwambiri kuposa mapiri 11 Mbps a B ndipo mochepa kwambiri kuposa 150 Mbps kapena kupitirira kwakukulu kwa N.
Mofanana ndi mitundu yambiri ya mauthenga, G sangathe kukwaniritsa malingaliro ake; Kugwirizana kwa 802.11g kumawomba malire a dera lopatsirana pakati pa 24 Mbps ndi 31 Mbps (ndi zotsala zomwe zimagwiritsidwa ntchito ndi zowonjezereka za protocol).
Onani Momwe Kufulumira Ndilili 802.11g Wi-Fi Networking? kuti mudziwe zambiri.
Momwe 802.11g Zimagwirira ntchito
G inaphatikizapo njira yothandizira pawailesi yotchedwa Orthogonal Frequency Division Multiplex (OFDM) yomwe idayambitsidwa ku Wi-Fi ndi 802.11a ("A"). Teknoloji ya OFDM inathandiza G (ndi A) kupindula kwambiri ndi ma network kuposa B.
Mosiyana ndi zimenezo, 802.11g analandira njira zofanana za ma GV zokhudzana ndi ma Wi-Fi ndi 802.11b. Kugwiritsa ntchito nthawiyi kunapatsa ma Wi-Fi zipangizo zazikulu kuposa zomwe A angapereke.
Pali njira 14 zomwe 802.11g zingagwire ntchito, ngakhale zina siziloledwa m'maiko ena. Maulendo ochokera kumsewu 1-14 amakhala pakati pa 2,412 GHz ndi 2.484 GHz.
G inali yapadera yokonzedwanso kwa mtanda. Izi zikutanthawuza kuti zipangizo zingagwirizane ndi mawotchi opanda waya ngakhale pamene malo opanda pakompyuta amatha kusintha ma Wi-Fi. Ngakhalenso zipangizo zatsopano za 802.11ac Wi-Fi masiku ano zitha kuthandizira kugwirizana kuchokera kwa makasitomala G pogwiritsira ntchito njira zofanana za ma GHz.
802.11g kwa Home Networking ndi Travel
Mitundu yambiri yamagetsi ndi makina ena a Wi-Fi anapangidwa ndi mafilimu a Wi-Fi akuthandizira G. Pogwiritsa ntchito zinthu zabwino kwambiri za A ndi B, 802.11g anakhala ofanana kwambiri ndi Wi-Fi panthawi yomwe Kubwezeretsedwa kwa malo ochezera kunyumba kunaphulikira padziko lonse lapansi.
Mabungwe ambiri apanyumba lerolino akugwiritsabe ntchito ma routers 802.11g . Pa 54 Mbps, maulendowa akhoza kukhala ndi ma intaneti othamanga kwambiri pa intaneti omwe akuphatikizapo masewero okhudzana ndi mavidiyo ndi masewera a masewera a pa Intaneti.
Zingapezedwe mopanda malire kudzera m'mabwalo awiri ogulitsira komanso ogulitsira. Komabe, magulu a G akhoza kufika pazikhazikitso mwamsanga pamene zipangizo zambiri zimagwirizanitsidwa komanso panthawi yomweyo, koma izi ndi zoona kwa intaneti iliyonse imene imayidya ndi zipangizo zambiri .
Kuwonjezera pa ma G routers omwe amapangidwira kukhazikika m'nyumba, 802.11g oyendetsa maulendo oyendayenda amapindula kwambiri ndi akatswiri amalonda ndi mabanja omwe amafunika kugawana mgwirizano umodzi wa Ethernet wodutsa pakati pa zipangizo zawo zopanda waya.
G (ndi ena N) oyendetsa maulendo angapezedwe m'malo ogulitsira malonda koma akhala osowa kwambiri ngati hotelo ndi mautumiki ena a pa intaneti akuchoka ku Ethernet kupita kumalo osungirako opanda waya ,
