Nangona i-4G ilayisensi eTshayina, ulwakhiwo lwenethiwekhi enkulu sele luqalile. Ukujongana nendlela yokukhula okuqhumayo yedatha yeselula, kuyimfuneko ukuqhubeka nokuphucula amandla enethiwekhi kunye nomgangatho wokwakha nenethiwekhi. Nangona kunjalo, ukusasazeka rhoqo, ukwanda kokuphazamiseka, kunye nemfuno yokwabelana ngesakhiwo kunye nezikhululo zeziseko ze-2G kunye ne-3G ziqhuba uphuhliso lwe-Antenation ye-Anlin, i-bandwidth ebanzi kunye nohlengahlengiso olubhetyebhetye ngakumbi.
I-4G yenethiwekhi yokugubungela.
Ungqingo oluhle lwenethiwekhi kunye nobungqingqwa obuthile bokungaziphathi zezixhobo ezimbini ukumisela umgangatho wenethiwekhi.
Inethiwekhi entsha yesizwe kufuneka ithathele ingqalelo ukwakhiwa komsebenzi wenethiwekhi ngelixa kugqibile ukugqiba kwethagethi. "Ngokubanzi, zintathu iindlela zokuphucula amandla enethiwekhi," uMlawuli we-Sheng Anner of Wireless Poires Sonsosution we-Wireless ye-Wireless ye-Wordcope United Tounity Unit, i-China yeendaba ze-elektroniki.
Inye yokusebenzisa i-frequency engakumbi yokwenza i-bandwidth ebanzi. Umzekelo, i-GSM ekuqaleni yayine-900mhz. Emva kwexesha, abasebenzisi bayanda kwaye bongezwa i-1800mhz frequency yongezwa. Ngoku i-3G kunye ne-4G frequency ingaphezulu. I-CD-LTE ye-TD-LTE ye-TD ye-TD ye-TD-LTE ineebhendi ezintathu, kwaye i-frequency ye-2.6gz isetyenzisiwe. Abanye abantu abakwishishini bakholelwa ukuba lo ngumda, ngenxa yokuba i-insunt-thendation ephezulu iya kuba nzima ngakumbi, kwaye igalelo kunye negalelo lezixhobo zingaphandle. Okwesibini kukwandisa inani lezikhululo zeziseko, nako yeyona ndlela isetyenziswayo. Okwangoku, ukuxinana kwezinto ezisisiseko kwizixeko ezikhulu neziphakathi kuncitshisiwe ukusuka kwi-avareji yesitishi esinye kwisikhululo sekhilomitha esinye kwisikhululo esinye se-200-300. Elesithathu kukuphucula ukusebenza ngempumelelo, nto leyo eyindlela yokufumana yonke itekhnoloji yonxibelelwano. Okwangoku, ukusebenza kwempumelelo kwe-4G yeyona nto iphakamileyo, kwaye ifikelele kwinqanaba le-100m le-100m eShanghai.
Ukuba nesibane esihle senethiwekhi kunye nobungqingqwa obuthile bomthamo wethamsanqa ziziseko ezimbini ezibalulekileyo zenethiwekhi. Ngokucacileyo, isikhundla se-China se-TD-LTE senza inethiwekhi esemgangathweni kwaye ime ngaphezulu kwemakethi ye-4G enamava aphezulu omsebenzisi. "Sibandakanyeka kulwakhiwo uninzi lwenethiwekhi ezingama-240 ze-LTE emhlabeni." "Ukusuka kumava ekomjini, kukho izinto ezintlanu kulwakhiwo lwenethiwekhi ye-LTE. Esokuqala kukulawula ingxolo yenethiwekhi; okwesibini kukucwangcisa kwaye ulawule icandelo elingenazingcingo; okwesine kukwenza i-a Umsebenzi olungileyo kumqondiso wokubuya, oko kukuthi, i-bandwidth yomqondiso we-Uplink kunye ne-Dollink Storlink Storlink Stoner kufuneka ibenzi ngokwaneleyo;
Iinkcukacha zobugcisa zovavanyo lolawulo lwengxolo.
Yingxaki yokwenyani ukulawula inqanaba lengxolo kwaye wenze abasebenzisi benethiwekhi abaphethe inethiwekhi bafumane ukufikelela ngesantya esiphezulu.
Ukwahluka kwesikimi se-3G ngokwandisa amandla othumelo, inethiwekhi ye-4G iya kuzisa ingxolo entsha ngokuphuculwa komqondiso. "Uhlobo lwenethiwekhi ye-4G kukuba ingxolo ayichaphazeli icandelo eligutyungelwe yi-eriyali, kodwa lichaphazela amacandelo athambileyo ePacket, ukusebenza kweyona ndawo Izinga lokuhambisa idatha lincitshisiwe, amava omsebenzisi ancitshisiwe, kwaye ingeniso inciphile. I-Wang Sheng yatsho, "Ukudelela inethiwekhi ye-4G ivela kwisikhululo sedatha, kwaye i-4G isondelelene nenethiwekhi ye-4G ye-4G yenethiwekhi inokuthi ifumane inqanaba, kufuneka silawule kwinqanaba lengxolo, kunjalo Ukuba umphetho wenethiwekhi unokufumana ukufikelela ngesantya esiphezulu, yingxaki esifuna ukuyisombulula. " Ukusombulula le ngxaki, kukho iimfuno ezininzi: Iimfuneko ezininzi, i-bandwidth yenxalenye ye-RF kufuneka ibe ngokubanzi ngokwaneleyo; Okwesibini, ukusebenza kokusebenza kwe-radio frequency yenethiwekhi kufuneka ilungele; Okwesithathu, i-bandwidth ye-Uplink Ibuyiselweyo kufuneka ibenzi ngokwaneleyo.
Kwinethiwekhi ye-2G ye-2G, ukugubungela inethiwekhi yokugquma kweSikhululo seSiseko seSiseko sikhulu. Iifowuni eziphathwayo zinokufumana imiqondiso kwizitishi ezahlukeneyo. I-2G yeefowuni ziya kutshitshiswa ngokuzenzekelayo kwisigqibo esisisiseko kunye nophawu olomeleleyo, ukutyeshela abanye. Kuba ayizukutshintsha rhoqo, ayizukuphazamisa naluphi na uphazamiso kwiseli elandelayo. Ke ngoko, kwinethiwekhi ye-GSM, kukho iindawo ezili-9 ukuya kwezi-12 ezinxunguphalo ezinokunyamezelwa. Nangona kunjalo, kwithuba le-3G, ukugqogqaka kwe-oversey yenethiwekhi kuya kuba nefuthe elikhulu kumthamo wenkqubo. Ngoku, i-eriyali ene-angle ihamba nge-angle isetyenziselwe i-angle isetyenziselwa ukugubungela amacandelo amathathu. Eli candelo lithathu le-LTE ifuna i-antenna yokusebenza ephezulu ukuba yenziwe ngendlela efanayo ne-3G. "I-Antenna ebizwa ngokuba yi-Erivena kuthetha ukuba xa usenza i-Antenne ye-ANTANNA ye-ANTANNA, ukugubungela kumacala omabini enethiwekhi kuyakhawuleza, ngenxa yoko, sinokubona ngokucacileyo ukuba iinethiwekhi ze-LTE ziphezulu kwaye iimfuno eziphezulu zezixhobo. " Wang Sheng utshilo.
ICandelo le-frequety iCandelo lokuZimela ngombane
Kuyimfuneko ukulawula umda wenethiwekhi echanekileyo ngokunciphisa ukuphazanyiswa kwesitishi. Eyona ndlela ilungileyo kukuqonda ulawulo lwe-antenna olude.
Ukusombulula ulawulo lonxibelelwano lwenethiwekhi, ikakhulu kuxhomekeke kwimiba emininzi: ukucwangciswa kwenethiwekhi, ukushiya umda owoneleyo wokuhamba rhoqo; Inqanaba lesibini, lesixhobo, inkqubo nganye yokwakha kufuneka ilawulwe kakuhle; Okwesithathu, inqanaba lokufaka. "Singene eChina ngo-1997 kwaye senza amatyala amaninzi. KwiKholeji eninzi, ekhethekileyo kwi-eriyali, siya kwenza uqeqesho lokuzibafundisa kwaye sisebenzise iqabane lethu. Kwangelo xesha, sikwaneqela ukuya Yenza iziqholo kunye ne-eriyali. "Iimveliso ezingenazingcingo, ngakumbi iimveliso zangaphandle, zibe neyona ndawo imbi yokusebenza kwiNkqubo yoNxibelelwano, ejongene nomoya, imvula, amaqondo obunzima obuphakathi, ke iimfuno zokuphakama ziphezulu kakhulu. "Iimveliso zethu zinokuma iminyaka eli-10 ukuya kwengama-30. Akululanga." Wang Sheng utshilo.
