igiciro cyo kongera ikimenyetso cya telefoni zigendanwa

I. Ni iki gituma amplifier y'amakuru itera imbere mu gice cy'ibanze?

Mu mishinga idakora neza yo gukwirakwiza ibimenyetso, uburyo bwo gukora bwa amplifier y'ibimenyetso igendanwa (isubiramo) ni ukwakira ibimenyetso bivuye kuri sitasiyo zo hanze, bikabyongerera imbaraga, hanyuma bikagezwa ku muyoboro w'imbere. Byiza, bigomba kongera imbaraga z'ibimenyetso bikenewe mu nzu gusa, nta kindi cyabangamira sitasiyo zo hanze.

                                                                                                           umuyoboro w'itumanaho rya telefoni zigendanwa zo mu biro

Ariko, iyo ibikoresho bidakozwe neza cyangwa imiterere ya antene idakwiye, amplifier ishobora gusubiza inyuma ikimenyetso cyo mu nzu cyongerewemo ijwi hanyuma ikacyohereza kuri sitasiyo y'ibanze, mu by'ukuri yohereza urusaku ruhoraho kandi yongera urusaku rw'aho sitasiyo y'ibanze. Ingaruka zirimo kugorwa na telefoni zigendanwa ziri hafi aho guhuza na sitasiyo y'ibanze, kugabanuka k'umuvuduko wa interineti, no guhamagara bihagaritswe; mu bihe bikomeye, bishobora kwangiza imikorere ya sitasiyo y'ibanze y'aho sitasiyo y'ibanze, bigatuma umukozi akora iperereza kandi agasaba ko ibikoresho bikurwaho.

Icyitonderwa: Amplifiers za telefoni ubwazo ntizitera ikibazo. Hamwe n'ibikoresho byujuje ibisabwa hamwe no gushyiraho no gukemura ibibazo neza, ikibazo cya sitasiyo y'ibanze gishobora kwirindwa burundu.

2. Impamvu enye z'ingenzi zitera ihungabana ry'ibiro by'ibanze

A. Kudashyira hamwe bihagije hagati y’Antena zo kohereza no kwakira (Bikunze kugaragara cyane)

Kudashyira hamwe bihagije hagati ya antene yo hanze yakira ikimenyetso cya sitasiyo y'ibanze na antene yohereza ubutumwa imbere bituma ibimenyetso bisohoka nyuma yo kwiyongera imbere, bigasubira kuri antene yo hanze. Iki kimenyetso kirazenguruka kandi kikazamuka hagati ya antene zombi, bigatuma ibikoresho byinjira mu buryo bwikora. Iki kimenyetso cyo kwihuza gisubira inyuma yerekeza kuri sitasiyo y'ibanze, cyongera urusaku rw'aho sitasiyo y'ibanze igera ndetse bigatera imbogamizi.

Imishinga myinshi y’ubwubatsi ikorerwa mu nyubako yibanda gusa ku mbaraga z’amajwi yo mu nzu, ikirengagiza intera iri hagati ya antene n’icyerekezo. Imishinga y’amazu n’iy’ubutaka ifite ubushobozi buke bwo gukwirakwiza amajwi ni bimwe mu bibazo bishobora gutera iki kibazo.

                                                                                                                           sisitemu y'ubuhanga bwo gukemura ibimenyetso idakomeye

B. Inyungu Ishyirwa Hejuru Cyane, Ingufu Zisohoka Zirenze Imipaka

Bamwe mu bahanga, mu gushaka imbaraga zuzuye z'amajwi yo mu nzu, bongera mu buryo butaziguye uburyo amplifier ya terefone igendanwa irushaho kwiyongera. Hanze, ikimenyetso cya sitasiyo y'ibanze cyamaze kuba cyiza; kongera ibimenyetso biremereye biremereye ikimenyetso cya uplink. Amplifier ikabije ya uplink ikoreshwa na terefone igendanwa ishobora "kurenga" sitasiyo y'ibanze, bigatera urujijo mu baturage bose bayikikije.

Igitekerezo kitari cyo: Kongera cyane si ko buri gihe biba byiza, kandi ikimenyetso cyuzuye imbere mu nzu ntibivuze ko gikora neza kurushaho.ItsindaAGC/MGCIngufu zigomba gushyirwaho neza hashingiwe ku mbaraga z'ibimenyetso by'umuterankunga aho hantu. Ubwoko bwose bwa Lintratek Technology bw'ibikoresho bisubiramo ubucuruzi bufite AGC automatic gain control, igabanya kwihuta kwa amplification ikabije kandi ikagabanya ibyago byo kwivanga kw'amakosa ya muntu mu gihe cyo gushyiraho.

ibyuma bitera inkunga terefone zigendanwa mu cyaro

C. Guhitamo nabi ikimenyetso cyo kongera ingufu: Kutajyanye n'imiterere y'aho ibintu biherereye n'imirongo y'ingufu z'ibikoresho

Urugero, amplifier y'amajwi agendanwa ifite imigozi itanu yatoranijwe mu buryo butari bwo ubwo hakenewe imigozi ibiri gusa y'amajwi adakomeye yo gukwirakwiza amajwi aho yari akenewe. Muri frequencies zimwe na zimwe aho amajwi ya sitasiyo y'ibanze yari akomeye, ibikoresho byakomeje gukora amplification ikomeye kuri izo migozi, bigatuma imigozi irenga kandi ikabangamira streets z'ibanze. Byongeye kandi, hari imishinga imwe n'imwe yakoresheje repeaters zidafite ireme, zidafite imikorere myiza yo kuyungurura kandi zidahagije, bigatuma habaho amajwi atari yo yabangamira streets z'ibanze zikikije.

3. Ni gute wakwirinda kubangamira sitasiyo y'abasirikare mbere y'igihe?

A. Shyira imbere uburyo bwo kwitandukanya antene

Menya neza ko ahantu hagati y’antene zo hanze n’izo mu nzu hatandukanye. Witondere icyerekezo cya antene; ibimenyetso bya antene zo mu nzu ntibigomba gusubira inyuma kuri antene zo hanze kugira ngo hirindwe ko zihinduka.

B. Hindura inyungu uko bikwiye, ushyira imbere AGC (Automatic Gain Control)

Ku bijyanye n'ubwikorezi buke bw'amajwi, ntugakurikire ahantu hose mu nzu udafite ubushobozi. Shyira imbere AGC igufasha. Inyinshi muri za amplifier za Linchuang Technology zikoresha uburyo bubiri bwa AGC/MGC, zihuza n'uburyo butandukanye bwo gukwirakwiza amajwi nk'utuzu tw'amashanyarazi, amazu manini, amazu yo munsi y'ubutaka, n'inganda.

C. Ibicuruzwa byatoranijwe bigomba guhuza n'imirongo y'amajwi ya sitasiyo y'ibanze aho bikorerwa.

Kora ubushakashatsi aho hantu kugira ngo wemeze imirongo nyayo y’urujya n’uruza ikoreshwa mu gace utuyemo, hitamo ibicuruzwa ukurikije ibyo ukeneye, kandi wirinde kurundanya imirongo myinshi y’urujya n’uruza mu buryo butari bwo; urebe neza ko ibicuruzwa byujuje ibisabwa kandi byemewe, kandi ureke ibikoresho bitujuje ubuziranenge cyangwa byahinduwe.

D. Kugenzura neza uburyo bwo kubaka

Fata imiyoboro y'ibikoresho byo kohereza ibikoresho kandi urebe neza ko amazi atagira aho anyura; banza ubare igihombo cy'ibikoresho byo kohereza ibikoresho mbere y'igihe kugira ngo wirinde ko ibimenyetso bisohoka; wirinde gushyira antene zo hanze mu buryo butaziguye neza.

E. Isuzuma nyuma yo kurangiza rikenewe.

Nyuma yo gutangira umushinga, reba uko intabaza y'ibikoresho ihagaze. Nta ntabaza y'itara ritukura igomba kubaho; icyarimwe, reba umuyoboro wa telefoni zigendanwa ukikije. Iyo nta gutinda kudasanzwe, gutangira umushinga bifatwa nk'aho byarangiye.

                                                                                                umushinga wo kongera imbaraga mu nyubako z'ibiro

4, Intambwe zihuse zo gukemura ibibazo ku kibazo cy'ihungabana ry'ibice biriho bya sitasiyo y'ibanze

1.）Gabanya inyungu ya amplifier y'amajwi ya telefoni igendanwa kandi urebe niba ikibazo cyagabanutse;

2. ） Genzura aho antene ebyiri ziherereye n'icyerekezo cyazo hanyuma wongere uburyo bwo kwitandukanya;

3.） Reba insinga n'ibihuza by'amashanyarazi kugira ngo birebe ko byangiritse cyangwa bidafite akamaro;

4. （Reba niba hari inzibutso zivuga ko zihindagurika. Iyo zihindagurika, zigomba guhita zivugururwa;

5. ）Niba ukoresha uburyo bwa MGC bwakoreshejwe n'intoki, hindukirira kuri AGC automatic gain control mode kugira ngo upime.
