intengo yokuqinisa isignali yeselula

I. Kuyini ukuphazamiseka okuphambene kwe-amplifier yesiginali esiteshini esiyisisekelo?

Kumaphrojekthi okumbozwa kwesignali abuthakathaka, umqondo osebenzayo we-mobile signal amplifier (i-repeater) ukuthola amasignali avela eziteshini zangaphandle, uwakhulise, bese uwanikeza kunethiwekhi yangaphakathi. Okungcono kakhulu, kufanele akhulise kuphela isignali edingekayo ngaphakathi, ngaphandle kokubangela ukuphazamiseka okwengeziwe eziteshini zangaphandle.

                                                                                                           isikhuthazi senethiwekhi yesignali yeselula yehhovisi

Kodwa-ke, uma imishini ingahlelwanga kahle noma ukwakheka kwe-antenna kungalungile, i-amplifier ingabuyisela emuva isignali yangaphakathi ekhulisiwe bese iyithumela emuva esiteshini esiyisisekelo, ngokuyisisekelo ithumele umsindo oqhubekayo futhi ikhulise umsindo wesiteshi esiyisisekelo. Imiphumela ihlanganisa ubunzima bamafoni aseduze ukuxhuma esiteshini esiyisisekelo, isivinini senethiwekhi esincishisiwe, kanye nezingcingo eziyekiwe; ezimweni ezimbi kakhulu, ingonakalisa ukusebenza kwesiteshi esiyisisekelo seseli, okwenza umqhubi aphenye futhi adinge ukuthi imishini isuswe.

Qaphela: Ama-amplifier esignali yeselula ngokwawo awabangeli ukuphazamiseka. Ngemishini ehambisanayo kanye nokufakwa kanye nokulungisa amaphutha okufanele, ukuphazamiseka kwesiteshi esiyisisekelo kungagwenywa ngokuphelele.

2. Izizathu ezine eziyinhloko ezibangela ukuphazamiseka kwesiteshi sesisekelo

A. Ukuhlukaniswa Okwanele Phakathi Kokudlulisa Nokwamukela Ama-Antenna (Okuvame Kakhulu)

Ukuhlukaniswa okwanele phakathi kwe-antenna yangaphandle ethola isignali yesiteshi esiyisisekelo kanye ne-antenna ethumela ngaphakathi kuholela ekuvuza kwesignali ngemva kokukhulisa ngaphakathi, kugeleze ku-antenna yangaphandle. Isignali iyajikeleza futhi ikhule phakathi kwama-antenna amabili, okubangela ukuzinyakazisa emishinini. Lesi signali esizinyakazisayo sibe sesibuyela emuva esiteshini esiyisisekelo, sikhulise ngqo umsindo wesiteshi esiyisisekelo futhi sibangele ukuphazamiseka.

Amaphrojekthi amaningi okwakha endaweni agxila kuphela emandleni esignali yangaphakathi, enganaki isikhala se-antenna kanye nokuqondiswa. Amaphrojekthi ezindlu zangasese kanye nezakhiwo ezingaphansi komhlaba ezinesignali esibuthakathaka yizimo eziyingozi kakhulu zale nkinga.

                                                                                                                           uhlelo lwesisombululo sesignali olubuthakathaka

B. Isethi Yokuthola Inzuzo Ephakeme Kakhulu, Amandla Okukhipha Adlula Imikhawulo

Abanye onjiniyela, befuna amandla aphelele esignali yangaphakathi, bakhulisa ngqo inzuzo ye-amplifier yesignali yocingo oluphathwayo. Ngaphandle, isignali yesiteshi esiyisisekelo isivele ilungile; ukukhulisa isignali okubaluleke kakhulu kugcwalisa isignali ye-uplink. Ukukhulisa i-uplink ngokweqile yi-repeater yocingo oluphathwayo, nakho, kungenza "kudlule" isiteshi esiyisisekelo, kubangele ukuphazamiseka emphakathini wonke ozungezile.

Umbono Oyiphutha: Ukwanda okuphezulu akuhlali kungcono, futhi isignali egcwele yangaphakathi ayisho ngempela ukusebenza okungcono.II-AGC/MGCI-gain idinga ukusethwa ngendlela efanele ngokusekelwe emandleni esignali yomnikeli endaweni. Lonke uhla lwe-Lintratek Technology lweziphindaphindo zezentengiselwano lufakwe i-AGC automatic gain control, ecindezela ngokuzenzakalelayo i-amplification ngokweqile futhi inciphise ingozi yokuphazamiseka okuvela emaphutheni abantu ngesikhathi sokusetha.

C. Ukukhethwa Okungalungile Kwe-Signal Booster: Ukungafani Phakathi Kwezimo Zendawo Namabhendi Emvamisa Yemishini

Isibonelo, i-amplifier yesignali yeselula enamabhendi amahlanu yakhethwa ngokungacabangi lapho kudingeka amabhendi amabili kuphela emvamisa yokumbozwa kwesignali okubuthakathaka endaweni. Kwamanye amabhendi emvamisa lapho amasignali esiteshi sendawo ayenamandla khona, imishini yayisasebenza ukukhulisa amandla amakhulu kulawo mabhendi, okwabangela ukugcwala kwe-uplink kanye nokuphazamiseka eziteshini zesisekelo. Ngaphezu kwalokho, amanye amaphrojekthi asebenzise ama-repeater angaphansi kwekhwalithi, angaqinisekisiwe anokusebenza kokuhlunga okubi kanye nokucindezelwa okwanele kwe-out-of-band, okwenza amasignali angamanga aphazamisa iziteshi zesisekelo ezizungezile.

3. Ungakugwema kanjani ukuphazamiseka kwesiteshi sesisekelo kusenesikhathi?

A. Beka phambili ukuhlukaniswa kwe-antenna

Qinisekisa ukuhlukaniswa kwendawo phakathi kwama-antenna angaphandle nangaphakathi. Naka ukuqondiswa kwe-antenna; izimpawu ze-antenna zangaphakathi akumele zibuyele emuva kuma-antenna angaphandle ukuvimbela ukuzinyakazisa.

B. Lungisa inzuzo ngokufanele, ubeke phambili i-AGC (Ukulawula Ukuzuza Okuzenzakalelayo)

Ukuze uthole ukumbozwa kwesignali okubuthakathaka, ungalandeli imigoqo egcwele ngaphakathi endlini ngokungazi. Beka phambili ukuvumela i-AGC. Iningi lama-amplifier esignali yeselula yezentengiselwano yeLinchuang Technology asekela izindlela ezimbili ze-AGC/MGC, ezivumelana nezimo ezahlukahlukene zokumbozwa eziyinkimbinkimbi njengemigudu, izindlu ezifuywayo, amagumbi angaphansi komhlaba, kanye namafektri.

C. Imikhiqizo ekhethiwe kumele ifane namabhendi emvamisa yesiteshi esiyisisekelo esisendaweni.

Yenza ucwaningo endaweni ukuqinisekisa amabhendi emvamisa angempela asetshenziswa endaweni, khetha imikhiqizo ngokwezidingo, futhi ugweme ukuqoqa amabhendi amaningi emvamisa ngokungazi; qinisekisa ukuthi imikhiqizo iyahambisana futhi iqinisekisiwe, futhi wenqabe imishini engaphansi kwezinga noma eguquliwe.

D. Qinisekisa amasu okwakha afanele

Qinisa izixhumi ze-feeder futhi uqinisekise ukuthi azingenwa amanzi; bala ukulahlekelwa yi-feeder kusengaphambili ukuze ugweme ukuvuza kwesignali; gwema ukubeka ama-antenna angaphandle ngqo maqondana neziteshi eziyisisekelo.

E. Kudingeka ukubuyekezwa ngemva kokuphothulwa.

Ngemva kokuqedwa kokuqalwa kwephrojekthi, qaphela isimo se-alamu yemishini. Akufanele kube khona i-alamu yokuzivuselela yokukhanya okubomvu; ngasikhathi sinye, qaphela inethiwekhi yeselula ezungezile. Uma kungekho ukulibaziseka okungavamile, ukuqalwa kwephrojekthi kubhekwa njengokuqediwe.

4, Izinyathelo Zokuxazulula Izinkinga Ezisheshayo Zokuphazamiseka Kwesiteshi Esiyisisekelo Esikhona

1.）Nciphisa inzuzo ye-amplifier yesignali yocingo oluphathwayo bese ubheka ukuthi ukuphazamiseka kuncishisiwe yini;

2.）Hlola indawo ehlobene kanye nokuma kwama-antenna amabili bese wandisa ukuhlukaniswa;

3.） Hlola ikhebula le-feeder kanye nezixhumi ukuze zingabi nobunzima noma umonakalo;

4. （Hlola ama-alamu okuzinyakazisa. Uma kwenzeka ukuzinyakazisa, kumele kuxazululwe ngokushesha;

5. ）Uma usebenzisa imodi ye-MGC eyenziwe ngesandla, shintshela kumodi yokulawula ukutholakala okuzenzakalelayo kwe-AGC ukuze uhlole.
