     Ngaba uyazi ukuba zeziphi iifrikhwensi eziqhele ukusetyenziswa kwiimpawu zeselfowuni?Namhlanje ukuba wonke umntu andise ulwazi.

Ukususela ekuphuhlisweni koshishino lwezonxibelelwano lwaseChina, ngokuthe ngcembe yenze ukuhlalisana kwe-2G / 3G / 4G / 5G imeko, ukuhanjiswa kwesignali yefowuni yeselula idluliselwa nge-frequency ethile, kwaye abaqhubi abathathu abakhulu banee-frequencies ezahlukeneyo kunye nemigangatho yenethiwekhi, eya kubangela kwifowuni enye ephathekayo phakathi kwabaqhubi abathathu abakhulu isenokungabi yimeko eqhelekileyo, ke abaqhubi abathathu abadla ngokusetyenziswa rhoqo yintoni? Kuthetha ukuthini ukuchongwa okusekwe rhoqo?

Iifrikhwensi zeempawu zefowuni eziphathwayo zabaqhubi abathathu abakhulu baseTshayina bahamba ngolu hlobo lulandelayo (Lintratek4G Mobile Repeateringenziwa ngokwezifiso ngokuhambelana neebhendi zamanye amazwe kunye nemimandla):

I-1, i-China Mobile: 885-909 (uplink), 930-954Mhz (downlink);

2, China Unicom: 909-915 (uplink), 954-960Mhz (downlink);

3, China Telecom: 825-835 (uplink), 870-880Mhz (downlink).

Ukubaluleka komqondiso wefowuni ephathwayo ngokusekwe kumaxesha amaninzi:

Uphawu loMqondiso G:
Igama elipheleleyo le-G yi-GPRS, eyeyenethiwekhi ye-2.5G kwaye ngumgangatho wothungelwano kubasebenzisi befowuni ye-GSM. Ukusukela ekuqaleni kwe-GRPS, iiselfowuni zinokungena ngokusemthethweni kwi-Intanethi;

Ukuchongwa koMqondiso E
Igama elipheleleyo le-E yi-EDGE, imfutshane kwi-teknoloji ye-GSM evolution, eyiteknoloji yenguqu esuka kwi-GSM ukuya kwi-3G. Isantya sikhawuleza kancinci kune-GPRS, eyeyenethiwekhi ye-2.75G. I-E yeyona ndlela iqhelekileyo yothumelo lwenethiwekhi engenazingcingo kwiminyaka apho ii-smart phone zisanda kuphuma.

Ukuchongwa komqondiso 3G

I-3G ibonisa inethiwekhi ye-3G eqhelekileyo, enezinga eliphezulu lokudluliselwa kwedatha kune-E. Ngexesha le-3G, kunye ne-bandwidth ephezulu kunye nokuhanjiswa okuzinzile, izicelo ze-Intanethi zeselula zaqala ukususela ngelo xesha;

Uphawu lomqondiso H
I-H + yinguqulo ephuculweyo ye-HSDPA HSPA +, yeyenethiwekhi ye-3.75G, inokufikelela kwisantya esiphezulu se-42Mbps esisezantsi, isantya sothungelwano siye saphuculwa ngakumbi;

Ukuchongwa komqondiso4G
I-4G yinethiwekhi esetyenziswa ngabantu abaninzi ngoku, kwaye ikwamfutshane kwisizukulwana sesine sothungelwano lweteknoloji. Ekuhanjisweni kwe-audio, ividiyo kunye nemifanekiso, isantya senze i-qualitative leap, kwaye izinga lokudluliselwa kwethiyori linokufikelela kwi-100Mbps;

Ukuchongwa komqondisoHD

I-HD iyisimboli yeefowuni eziphezulu, oko kukuthi, i-VoLTE, ebizwa ngokuba yi-high-definition voice, nayo inethiwekhi ye-4G. Indima enkulu yeVolTE kukuba iifowuni zezwi azisathwalwa ngamanethiwekhi e-2G / 3G, kwaye iinethiwekhi ze-4G zisetyenziselwa ukuhambisa idatha yezwi, ukuxhasa iteknoloji yekhowudi yolwimi oluphezulu, umgangatho wefowuni uphuculwe kakhulu, kwaye uxhasa ukufikelela kwi-Intanethi ngelixa uthetha.

Itekhnoloji ye-Lintratek ye-4g ephindaphinda i-mobile egubungela amazwe angama-155 kunye nemimandla kwihlabathi liphela, inokubonelela abathengi ngeenkonzo ezicwangcisiweyo ezilungiselelwe ukunceda abasebenzisi ukusombulula iimfuno zophawu lonxibelelwano,Lintratekuzibophelele ukuba ube yinkokeli yeshishini lebhulorho ebuthathaka, ukuze ihlabathi lingabi nandawo liyimfama, ukuze wonke umntu unxibelelwano lungabinamqobo!
