Ukubukeka kwimbali kwi-Wi-Fi technology
I-802.11g yi- IEEE ye-Intanethi ye-Intanethi ye-Intanethi . Njengezinye iinguqulelo ze- Wi-Fi , i-802.11g (ngokubhekiselele ekuthiwa "G") isekela uxhulumaniso lwengingqi ye-wireless (WLAN) phakathi kweekhomputha, ii-router routs , kunye nezinye iifowuni zabasebenzisi.
G yavunyelwana ngoJuni ka-2003, kwaye yatshintsha umgangatho omdala wama- 802.11b ("B"), ekugqibeleni wagqithiselwa ngu- 802.11n ("N") kunye nemigangatho emitsha.
Ukukhawuleza Kukuphi I-802.11g?
I-802.11g I-Wi-Fi isekela ubuninzi bee- bandwidth ye-network ye-54 Mbps , ephakamileyo kakhulu kune-11 Mbps isilinganiselo se-B kwaye ixabiso elingaphantsi kwama-150 Mbps okanye ukukhawuleza okukhulu kwe-N.
Njengayezinye iindidi zokunxibelelana, i-G ayikwazi ukufikelela kwisilinganisi esiphezulu kwisenzo; Ukuqhagamshelana kwama-802.11g kufana nesithintelo somda wokudluliselwa kwedatha phakathi kwee-24 Mbps kunye ne-31 Mbps (kunye nomda womda we-network osetshenziswe ngongaphezulu kweprotocol).
Uyabona indlela echanekileyo ngayo i-802.11g yokunxibelelana kwe-Wi-Fi? ngolwazi olungakumbi.
802.11g Isebenza njani
G iquka inxibelelwano yomsakazo ebizwa ngokuthi i- Orthogonal Frequency Division Multiplex (i-OFDM) eyayisungulwe ekuqaleni kwi-Wi-Fi kunye ne- 802.11a ("A"). I-teknoloji ye-OFD yenza ukuba iG (kunye no-A) bafezekise kakhulu ukusebenza kwenethiwekhi kunokuba iB.
Ngakolunye uhlangothi, i-802.11g yafumana i-2.4 GHz uluhlu lwee-frequencies zokuqala zonxibelelwano oluqaliswe kwi-Wi-Fi kunye ne-802.11b. Ukusebenzisa eli qhekeza kwanika ama-Wi-Fi amacebo amaninzi kakhulu kunokuba yi-A anokunikela.
Kukho amajelo angama-14 anokwenziwa ngu-802.11g, nangona amanye asemthethweni kwamanye amazwe. Iimvama ezivela kwinqanaba 1-14 liphakathi kwe-2.412 GHz ukuya kwi-2.484 GHz.
G yenzelwe ngokukhethekileyo ukuhambelana nokuhamba. Oko kuthetha ukuthini ukuba iifowuni ziyakwazi ukudibanisa amanethiwekhi angenawaya nangona indawo yokufikelela engenazintambo isebenza ngeenguqu ezahlukeneyo ze-Wi-Fi. Ngona i- 802.11ac idivayisi ye- Wi-Fi namhlanje inokuxhasa uxhulumaniso oluvela kwiiklayenti zeG ezisebenzisa ezi ndlela zokusebenza ezifanayo 2.4 GHz.
I-802.11g yoNxibelelwano lweKhaya kunye nohambo
Iimpawu ezininzi kunye neemodeli zeekhompyutheni kunye nezinye iifowuni ze-Wi-Fi zenziwe ngama-radios ase-Wi-Fi axhasa uG. Njengoko idibanise ezinye zezinto eziphambili ze-A ne-B, i-802.11g yaba ngumgangatho ophezulu kwi-Wi-Fi ngexesha Ukwamkelwa kwenethiwekhi yasekhaya kubhujiswe emhlabeni jikelele.
Amanethiwekhi amaninzi asekhaya namhlanje asebenzayo usebenzisa ii-router 802.11g . Kwama-54 Mbps, aba routers bangaqhubeka bexhamla kwi-intanethi ye-intanethi ye-intanethi kubandakanya ukuhanjiswa kwevidiyo ezisisiseko kunye nokusetyenziswa kwezemidlalo kwi-intanethi.
Ziyakuthi zifumaneke zingenangqiqo kwiindawo zokuthengisa ezithengiswayo. Nangona kunjalo, iinqununu ze-G zinokufikelela kwimida yokusebenza ngokukhawuleza xa amadivayisi amaninzi axhunyiwe kwaye asebenzayo, kodwa oku kuyinyaniso kunoma iyiphi inethwekhi esetyenziswa ngamadivayisi amaninzi .
Ukongeza kwii-routers ezijoliswe ekufakweni okuzinzileyo kumakhaya, ii-routers zokuhamba nge-802.11g zafumana ukugqithiswa okukhulu kunye neengcali zezoshishino kunye neentsapho ezifunekayo ukwabelana ngokuxhunyelelwa kwe- Ethernet eyodwa kunye neefowuni zabo ezingenazintambo.
I-G (kunye ne-N) ii-routers zokuhamba ziyakwazi ukufumaneka kwiindawo zokuthengisa kodwa zanda kakhulu njengehotele kunye nezinye iinkonzo ze-intanethi ezisuka kwi-Ethernet ukuya kwiindawo zokungena nge-wireless ,
