Ungayikhetha njani i-frequencies yesignali yefowuni yeselula ye-3g 4g lte repeter?

Ungayikhetha njani i-frequencies yesignali yefowuni yeselula ye-3g 4g lte repeter?

     Uyazi ukuba zeziphi iifrequencies ezisetyenziswa rhoqo kwiimpawu zeselfowuni?Namhlanje wonke umntu makakhulise ulwazi.

Ukususela ekuphuhlisweni koshishino lonxibelelwano lwaseTshayina, kuye kwakha ngokuthe ngcembe ukuhambelana kwemeko ye-2G/3G/4G/5G, ukuhanjiswa kwesignali yonxibelelwano lwefowuni ephathwayo kudluliselwa ngefrikhwensi ethile, kwaye abaqhubi abathathu abakhulu banefrikhwensi ezahlukeneyo kunye nemigangatho yenethiwekhi, nto leyo eya kubangela ukuba ifowuni enye ephathwayo phakathi kwabaqhubi abathathu abakhulu ingabi yimeko eqhelekileyo, ngoko ke abaqhubi abathathu abaqhelekileyo basebenzisa ifrikhwensi yintoni? Kuthetha ukuthini ukuchongwa okusekelwe kwifrikhwensi?

Iifrikhwensi zemiqondiso yefowuni ephathwayo zabaqhubi abathathu abakhulu baseTshayina ngokubanzi zezi zilandelayo (iLintratekIsiphindaphindi seSelfowuni se-4Gingenziwa ngokwezifiso ngokweebhendi zamaza zamanye amazwe kunye nemimandla):

1, iTshayina ephathwayo: 885-909 (uplink), 930-954Mhz (downlink);

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

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

Ukubaluleka kwesignali yefowuni ephathwayo ngokusekelwe kwimvamisa:

Ukuchongwa kweSignali G:
Igama elipheleleyo le-G yi-GPRS, elikwinethiwekhi ye-2.5G kwaye liyimigangatho yenethiwekhi yabasebenzisi beefowuni zeselula ze-GSM. Ukususela ekuqaleni kwe-GRPS, iifowuni eziphathwayo zinokusebenzisa i-intanethi ngokusesikweni;

Ukuchonga uphawu E
Igama elipheleleyo le-E yi-EDGE, isifinyezo setekhnoloji yokuguquka kwe-GSM, eyitekhnoloji yokutshintsha ukusuka kwi-GSM ukuya kwi-3G. Isantya sikhawuleza kancinci kune-GPRS, eyinethiwekhi ye-2.75G. I-E yindlela yokudlulisa inethiwekhi engenazingcingo yeselula kwiminyaka apho ii-smartphones zisandula ukuphuma.

Ukuchonga isignali 3G

I-3G ibonisa inethiwekhi eqhelekileyo ye-3G, enesantya esiphezulu sokudluliselwa kwedatha kune-E. Kwixesha le-3G, nge-bandwidth ephezulu kunye nokudluliselwa okuzinzileyo, usetyenziso lwe-intanethi yeselula lwaqala ukususela ngelo xesha;

Ukuchonga uphawu H
I-H+ yinguqulelo ephuculweyo ye-HSDPA HSPA+, yeyenethiwekhi ye-3.75G, inokufikelela kwisantya esiphezulu se-42Mbps downlink, isantya senethiwekhi siphuculwe ngakumbi;

Ukuchongwa kwesiginali4G
I-4G yinethiwekhi esetyenziswa ngabantu abaninzi ngoku, kwaye ikwafutshane netekhnoloji yonxibelelwano lweselula yesizukulwana sesine. Ekudlulisweni kweaudio, ividiyo kunye nemifanekiso, isantya senze inqanaba eliphezulu, kwaye izinga lokudluliselwa kwethiyori linokufikelela kwi-100Mbps;

Ukuchongwa kwesiginaliHD

I-HD luphawu lweefowuni ezinentsingiselo ephezulu, oko kukuthi, i-VoLTE, ebizwa ngokuba yilizwi elinentsingiselo ephezulu, elikwayinethiwekhi ye-4G. Eyona ndima inkulu ye-VolTE kukuba iifowuni zelizwi azisaphathwa ziinethiwekhi ze-2G /3G, kwaye iinethiwekhi ze-4G zisetyenziselwa ukudlulisa idatha yelizwi, ukuxhasa ubuchwepheshe obuphezulu bokubhala iikhowudi zolwimi, umgangatho wefowuni uphucuke kakhulu, kwaye uxhasa ukufikelela kwi-intanethi ngelixa uthetha.

Itekhnoloji yeLintratek, i-4g mobile repeater, igubungela amazwe ali-155 kunye nemimandla kwihlabathi liphela, inokubonelela abathengi ngeenkonzo zobungcali ezenzelwe wena ukunceda abasebenzisi basombulule iimfuno zesignali yonxibelelwano,I-LintratekUzimisele ukuba yinkokeli yoshishino lwebhulorho yesiginali ebuthathaka, ukuze ihlabathi lingabi naziphazamiso, ukuze wonke umntu angabi nemiqobo yonxibelelwano!
