Nkhaniyi ikupereka chithunzithunzi cha zigawo zamagetsi zamkati mwa chipangizo chobwereza ma signali yam'manja. Opanga ochepa okha ndi omwe amaulula zigawo zamkati mwa chipangizo chawo chobwereza ma signali kwa ogula. M'malo mwake, kapangidwe ndi ubwino wa zigawo zamkatizi zimagwira ntchito yofunika kwambiri pakugwira ntchito konse kwa chipangizocho.chobwereza mawu a pafoni.
Ngati mukufuna kufotokozera kosavuta momwe chobwereza mawu ogwiritsira ntchito pafoni chimagwirira ntchito,Dinani apa.
Mfundo Zoyambira za Mobile Signal Repeater
Monga momwe zasonyezedwera pachithunzi pamwambapa, mfundo yaikulu ya wobwereza chizindikiro cha mafoni ndikukulitsa zizindikiro pang'onopang'ono. Obwereza chizindikiro cha mafoni amakono omwe ali pamsika amafunikira magawo angapo a kukulitsa pang'ono kuti akwaniritse phindu lomwe mukufuna. Chifukwa chake, phindu lomwe lili pachithunzi pamwambapa likuyimira gawo limodzi lokha la phindu. Kuti mukwaniritse phindu lomaliza, magawo angapo a kukulitsa amafunika.
Nayi mawu oyamba a ma module omwe amapezeka mu foni yobwereza mawu:
1. Gawo Lolandirira Zizindikiro
Gawo lolandirira mauthenga limayang'anira kulandira zizindikiro zakunja, makamaka kuchokera ku malo oyambira kapena ma antenna. Limajambula zizindikiro za wailesi zomwe zimatumizidwa ndi siteshoni yoyambira ndikuzisintha kukhala zizindikiro zamagetsi zomwe amplifier imatha kuzikonza. Gawo lolandirira mauthenga nthawi zambiri limaphatikizapo:
Zosefera: Izi zimachotsa ma frequency osafunikira ndikusunga ma frequency ofunikira a ma signal a m'manja.
Chowonjezera Phokoso Lochepa (LNA): Izi zimakulitsa chizindikiro chofooka chomwe chikubwera pomwe zimachepetsa phokoso lowonjezera.
Zigawo Zamkati-chobwereza mawu ogwiritsira ntchito pafoni kunyumba
2. Gawo Lokonza Zizindikiro
Chipangizo chogwiritsira ntchito ma siginolo chimakulitsa ndikusintha ma siginolo olandiridwa. Nthawi zambiri chimaphatikizapo:
Modulator/Demodulator (Modemu): Izi zimasinthasintha ndikuchepetsa chizindikirocho kuti zitsimikizire kuti chikugwirizana ndi njira zolumikizirana zomwe zimagwiritsidwa ntchito.
Purosesa ya Chizindikiro cha Digito (DSP): Imayang'anira kukonza bwino ma signal ndikuwongolera, kukonza mtundu wa ma signal ndikuchepetsa kusokoneza.
Kuwongolera Kupeza Maginito (AGC): Kumasintha kuchuluka kwa maginito kuti zitsimikizire kuti kumakhalabe mkati mwa mulingo woyenera—kupewa kufooka kwa maginito ndi kukulitsa kwambiri komwe kungayambitse kudzisokoneza kapena kusokoneza zida zina.
3. Gawo Lokulitsa Mphamvu
Chokulitsa mphamvu (PA) chimawonjezera mphamvu ya chizindikiro kuti chiwonjezere kuchuluka kwa kufalikira kwake. Pambuyo pokonza chizindikiro, chokulitsa mphamvu chimakulitsa chizindikirocho ku mphamvu yofunikira ndikuchitumiza kudzera mu antenna. Kusankha kwa chokulitsa mphamvu kumadalira mphamvu yofunikira ndi malo ophimba. Pali mitundu iwiri ikuluikulu:
Ma Linear Amplifiers: Izi zimasunga ubwino ndi kumveka bwino kwa chizindikiro popanda kusokoneza.
Ma Amplifiers Osalunjika: Amagwiritsidwa ntchito m'malo apadera, nthawi zambiri pofikira malo ambiri, ngakhale kuti angayambitse kusokonekera kwa chizindikiro.
4. Magawo Oletsa Kuwongolera Ndemanga ndi Kuletsa Kusokoneza
Gawo Loletsa Kuyankha: Pamene amplifier itumiza chizindikiro champhamvu kwambiri, chingayambitse kuyankha pa antenna yolandira, zomwe zimapangitsa kuti pakhale kusokoneza. Magawo oletsa kuyankha amathandiza kuthetsa kusokoneza kumeneku.
Gawo Lolekanitsa: Limaletsa kusokonezana pakati pa zizindikiro zolandirira ndi zotumizira, kuonetsetsa kuti amplifier ikugwira ntchito bwino.
Kuletsa Phokoso ndi Zosefera: Kuchepetsa kusokoneza kwa chizindikiro chakunja, kuonetsetsa kuti chizindikirocho chikukhalabe choyera komanso champhamvu.
5. Gawo Lotumizira Zizindikiro
Gawo Lotumizira: Gawoli limatumiza chizindikiro chokonzedwa ndi kukulitsidwa kudzera mu antenna yotumizira kudera lomwe lili ndi malo ofikira, kuonetsetsa kuti zida zam'manja zimalandira chizindikiro chowonjezereka.
Wolamulira Mphamvu Yotumizira: Amayang'anira mphamvu yotumizira kuti aletse kukulitsa kwambiri, komwe kungayambitse kusokoneza, kapena kukulitsa pang'ono, komwe kungayambitse zizindikiro zofooka.
Antena Yotsogolera: Kuti chizindikiro chikhale cholunjika kwambiri, antenna yotsogolera ingagwiritsidwe ntchito m'malo mwa yolunjika mbali zonse, makamaka pofikira malo akuluakulu kapena powonjezera chizindikiro.
6. Gawo Lopereka Mphamvu
Chigawo Chopereka Mphamvu: Chimapereka mphamvu yokhazikika kwa chobwereza chizindikiro, nthawi zambiri kudzera mu chosinthira cha AC-to-DC, kuonetsetsa kuti chikugwira ntchito bwino pansi pa mikhalidwe yosiyanasiyana ya magetsi.
Gawo Loyang'anira Mphamvu: Zipangizo zapamwamba zitha kukhalanso ndi zinthu zoyang'anira mphamvu kuti ziwongolere kugwiritsa ntchito mphamvu moyenera ndikuwonjezera nthawi ya chipangizocho.
7. Gawo Loyeretsera Kutentha
Dongosolo Loziziritsira: Zobwerezabwereza zizindikiro zimapanga kutentha panthawi yogwira ntchito, makamaka ma amplifier amphamvu ndi zida zina zamphamvu kwambiri. Dongosolo loziziritsira (monga ma heat sink kapena mafani) limathandiza kusunga kutentha koyenera kuti chipangizocho chisatenthe kwambiri komanso chisawonongeke.
8. Gulu Lolamulira ndi Zizindikiro
Control Panel: Ma signal ena obwerezabwereza amabwera ndi kuwonetsera komwe kumalola ogwiritsa ntchito kusintha makonda, kukonza magwiridwe antchito, komanso kuyang'anira makinawo.
Zizindikiro za LED: Ma nyali awa amasonyeza momwe chipangizocho chikugwirira ntchito, kuphatikizapo mphamvu ya chizindikiro, mphamvu, ndi momwe chikugwirira ntchito, zomwe zimathandiza ogwiritsa ntchito kudziwa ngati chobwerezabwereza chikugwira ntchito bwino.
9. Madoko Olumikizirana
Khomo Lolowera: Limagwiritsidwa ntchito polumikiza ma antenna akunja (monga, zolumikizira za mtundu wa N kapena F).
Khomo Lotulutsira: Lolumikiza ma antenna amkati kapena kutumiza zizindikiro ku zipangizo zina.
Doko Losinthira: Ma repeater ena angaphatikizepo ma port osinthira ma gain ndi ma frequency settings.
10. Kapangidwe ka Mpanda ndi Chitetezo
Chotchingira cha wobwerezabwereza nthawi zambiri chimapangidwa ndi chitsulo, chomwe chimathandiza kuteteza ku kusokonezedwa kwakunja ndikuletsa kusokonezedwa kwamagetsi (EMI). Zipangizo zina zimakhalanso ndi zotchingira zosalowa madzi, fumbi, kapena shockproof kuti zipirire malo akunja kapena ovuta.
Zigawo Zamkati-chobwereza mawu amalonda pafoni
Chobwerezabwereza chizindikiro choyenda chimawonjezera zizindikiro kudzera mu ntchito yogwirizana ya ma module awa. Dongosolo limalandira ndikukulitsa chizindikirocho musanatumize chizindikiro cholimbikitsidwa kudera lomwe likuphimba. Mukasankha chobwereza chizindikiro choyenda, ndikofunikira kuonetsetsa kuti ma frequency band ake, mphamvu, ndi phindu lake zikugwirizana ndi zosowa zanu, makamaka m'malo ovuta monga ngalande kapena pansi pomwe kukana kusokoneza ndi kuthekera kokonza chizindikiro ndikofunikira.
Chifukwa chake, kusankhawopanga wodalirika wobwereza mawu a pafonindiye kiyi.LintratekKampaniyi, yomwe idakhazikitsidwa mu 2012, ili ndi zaka zoposa 13 zogwira ntchito popanga makina obwerezabwereza zizindikiro—kuyambira nyumba zogona mpaka malo ogulitsira, kuphatikizapo makina obwerezabwereza a fiber optic ndi malo owulutsira mawu mwachindunji. Kampaniyo ikufuna zida zapamwamba kwambiri zogulira zinthu zawo, kuonetsetsa kuti zikugwira ntchito bwino.
