mtengo wolimbikitsira chizindikiro cha foni yam'manja

I. Kodi kusokoneza kwa amplifier ya chizindikiro ku siteshoni yoyambira ndi chiyani?

Mu mapulojekiti ofooka okhudza zizindikiro, njira yogwirira ntchito ya amplifier ya ma signal (yobwerezabwereza) ndikulandira zizindikiro kuchokera ku malo oyambira akunja, kuzikulitsa, kenako kuzipereka ku netiweki yamkati. Mwachiyembekezo, ziyenera kungokulitsa chizindikiro chofunikira mkati, popanda kusokoneza malo oyambira akunja.

                                                                                                           chowonjezera cha netiweki ya chizindikiro cha foni yam'manja ku ofesi

Komabe, ngati chipangizocho sichinakonzedwe bwino kapena kapangidwe ka antenna sikali kolondola, amplifier ikhoza kusintha chizindikiro chamkati chokwezedwa ndikuchitumiza ku siteshoni yoyambira, makamaka kutumiza phokoso losalekeza ndikuwonjezera phokoso la siteshoni yoyambira. Zotsatira zake ndi monga kuvutika kwa mafoni apafupi kulumikizana ndi siteshoni yoyambira, kuchepa kwa liwiro la netiweki, komanso kuyimba foni mochedwa; pazochitika zazikulu, zimatha kuchepetsa magwiridwe antchito a siteshoni yoyambira ya foni, zomwe zimapangitsa wogwiritsa ntchito kufufuza ndikupempha kuti chipangizocho chichotsedwe.

Dziwani: Ma amplifiers a ma signali apafoni okha samayambitsa kusokoneza. Ndi zida zovomerezeka komanso kuyika bwino ndi kukonza zolakwika, kusokoneza kwa siteshoni ya base kungapewedwe kotheratu.

2. Zifukwa zinayi zazikulu zomwe zimayambitsa kusokonezeka kwa siteshoni ya base

A. Kusakwanira Kupatula Pakati pa Kutumiza ndi Kulandira Ma Antena (Ofala Kwambiri)

Kusakwanira kulekanitsidwa pakati pa antenna yakunja yolandira chizindikiro cha siteshoni yapansi ndi antenna yotumizira yamkati kumapangitsa kuti chizindikirocho chituluke pambuyo pokulitsa mkati, ndikubwerera ku antenna yakunja. Chizindikirocho chimazungulira ndikukulirakulira pakati pa antenna ziwirizi, zomwe zimapangitsa kuti chipangizocho chizigwedezeka chokha. Chizindikiro chodzigwedeza ichi chimabwerera ku siteshoni yapansi, ndikuwonjezera phokoso la siteshoni yapansi ndikuyambitsa kusokoneza.

Mapulojekiti ambiri omanga pamalopo amangoyang'ana mphamvu ya chizindikiro chamkati, kunyalanyaza mtunda wa ma antenna ndi momwe amayendera. Mapulojekiti a nyumba zazing'ono ndi zipinda zapansi zomwe zimakhala ndi ma signal ochepa ndi zinthu zomwe zimayambitsa vutoli.

                                                                                                                           njira yofooka yothetsera zizindikiro

B. Kupeza Ndalama Kuli Kwambiri, Mphamvu Yotulutsa Imaposa Malire

Mainjiniya ena, pofuna mphamvu zonse zamkati mwa foni, amawonjezera mwachindunji phindu la amplifier ya foni yam'manja. Kunja, chizindikiro cha siteshoni yapansi chili kale bwino; kukulitsa chizindikiro china chofunikira kumawonjezera mphamvu ya chizindikiro cha uplink. Kukulitsa kwambiri kwa uplink ndi chobwerezabwereza mafoni kungathe "kugonjetsa" siteshoni yapansi, zomwe zimapangitsa kuti anthu onse ozungulira asokonezeke.

Lingaliro Lolakwika: Kuwonjezeka kwakukulu sikukhala bwino nthawi zonse, ndipo chizindikiro chonse chamkati sichitanthauza kuti chikugwira ntchito bwino.TheAGC/MGCKupeza mphamvu kuyenera kukhazikitsidwa moyenera kutengera mphamvu ya chizindikiro cha wopereka pamalopo. Mitundu yonse ya ma repeater amalonda a Lintratek Technology ili ndi AGC automatic gain control, yomwe imaletsa kukula kwakukulu ndikuchepetsa chiopsezo cha kusokonezedwa ndi zolakwika za anthu panthawi yokhazikitsa.

C. Kusankha Kolakwika kwa Chizindikiro Chothandizira: Kusagwirizana Pakati pa Mikhalidwe ya Malo ndi Ma Frequency Band a Zipangizo

Mwachitsanzo, chojambulira mawu cha mafoni cha magulu asanu chinasankhidwa mosazindikira pamene magulu awiri okha afupipafupi omwe anali ndi chizindikiro chofooka amafunika pamalopo. M'magulu ena afupipafupi omwe zizindikiro za siteshoni yapafupi zinali zolimba, zidazo zinkagwirabe ntchito yowonjezera mphamvu kwambiri pa magulu amenewo, zomwe zinapangitsa kuti maulumikizidwe akwere ndi kusokoneza malo oyambira. Kuphatikiza apo, mapulojekiti ena adagwiritsa ntchito ma repeater osavomerezeka, osavomerezeka omwe anali ndi magwiridwe antchito osasefa komanso osakwanira kuletsa ma out of-band, zomwe zimapangitsa kuti ma signal abodza omwe amasokoneza malo ozungulira.

3. Kodi mungapewe bwanji kusokonezedwa ndi siteshoni ya sitima pasadakhale?

A. Ikani patsogolo kudzipatula kwa antenna

Onetsetsani kuti pali malo pakati pa ma antenna akunja ndi amkati. Samalani ndi momwe ma antenna amayendera; zizindikiro za ma antenna amkati siziyenera kubwereranso ku ma antenna akunja kuti zisadzigwedeze okha.

B. Sinthani phindu moyenera, ndikuyika patsogolo AGC (Automatic Gain Control)

Kuti muteteze ma signal osalimba, musatsatire malo odzaza mkati mwa nyumba. Ikani patsogolo AGC yothandiza. Ma amplifiers ambiri a Linchuang Technology amalonda a mafoni amathandizira ma AGC/MGC awiriawiri, omwe amasintha malinga ndi zochitika zosiyanasiyana zovuta monga ma tunnel, ma villas, zipinda zapansi, ndi mafakitale.

C. Zogulitsa zomwe zasankhidwa ziyenera kufanana ndi ma frequency band enieni a siteshoni ya base omwe ali pamalopo.

Chitani kafukufuku pamalopo kuti mutsimikizire ma frequency band enieni omwe akugwiritsidwa ntchito kwanuko, sankhani zinthu malinga ndi zosowa zanu, ndipo pewani kusonkhanitsa ma frequency band angapo mosazindikira; onetsetsani kuti zinthuzo zikugwirizana ndi malamulo ndi ziphaso, ndipo tsutsani zida zosakwanira kapena zosinthidwa.

D. Onetsetsani kuti njira zomangira zili bwino

Limbitsani zolumikizira za feeder ndikuwonetsetsa kuti madzi salowa; werengerani kutayika kwa feeder pasadakhale kuti mupewe kutayikira kwa chizindikiro; pewani kuyika ma antenna akunja moyang'anizana ndi malo oyambira.

E. Kuwunikanso pambuyo pomaliza ndikofunikira.

Pambuyo poti ntchito yoyambitsa pulojekiti yatha, yang'anani momwe alamu ya zida imaonekera. Sipayenera kukhala alamu yodzipangitsa kudzikuza; nthawi yomweyo, yang'anani netiweki ya mafoni yozungulira. Ngati palibe kuchedwa kwachilendo, ntchito yoyambitsa pulojekiti imaonedwa kuti yatha.

                                                                                                pulojekiti yolimbikitsira chizindikiro chofooka cha nyumba yaofesi

4, Njira Zothetsera Mavuto Mwachangu Pakusokoneza Malo Oyambira

1.）Chepetsani phindu la amplifier ya chizindikiro cha foni yam'manja ndipo yang'anani ngati kusokoneza kwachepa;

2.） Yang'anani malo ndi momwe ma antenna awiriwa alili ndikuwonjezera kudzipatula;

3.） Yang'anani chingwe chodyetsa ndi zolumikizira kuti zisamayende bwino kapena kuwonongeka;

4. （Yang'anani ma alarm odzigwedeza okha. Ngati kudzigwedeza kokha kwachitika, kuyenera kuthetsedwa nthawi yomweyo;

5. ）Ngati mukugwiritsa ntchito njira ya MGC yogwiritsira ntchito pamanja, sinthani ku njira yowongolera yodziwikiratu ya AGC kuti muyesedwe.
