Ndi zaka khumi ndi zinayi ndikuthandizira okhazikitsa ma RF ndi ogwirizana nawo padziko lonse lapansi, ndawona njira zazitali zogwirira ntchito zapansi panthaka zikubweretsa zovuta zovuta kwambiri kwa magulu opanga mainjiniya. Pulojekiti yeniyeni iyi yochokera ku Yibin, Kum'mwera chakumadzulo kwa China, ikuwonetsa momwe njira yothetsera ma netiweki am'manja yokonzedwa bwino imathetsera zosowa zovuta zolumikizirana mkati mwa zomangamanga zofunika kwambiri zamagetsi.
Ngalande iyi ndi gawo lofunika kwambiri lothandizira pulojekiti yayikulu yamagetsi ya Sichuan-Chongqing UHV yomwe imatumiza magetsi okwana 35 biliyoni kWh chaka chilichonse. Khonde lonse lamagetsi limatalika makilomita 4.5, logawika m'magawo awiri a msewu wa yunivesite ndi gawo la msewu wa Changcui wa makilomita 2.5.
Magulu a polojekitiyi amafunikira chithandizo chonse cha 4G kwa ogwira ntchito atatu a telecom am'deralo. Maulalo odalirika a mafoni anali osatheka kukambirana kuti agwire ntchito yoyang'anira nthawi zonse komanso kuti athandize pa nthawi yadzidzidzi panthawi yeniyeni pansi pa nthaka.
Mphepete mwa msewu wautali wotsekedwawu, womwe uli pansi pa nthaka mamita 15, umabweretsa zotchinga zambiri zolimba. Zingwe zamagetsi zolimba zomwe zili mkati mwake zimapanga phokoso lalikulu lamagetsi lomwe limayambitsa kung'anima kwa ma signal ndi kuchedwa kwa netiweki.
Kutayika kwa chizindikiro kumachitika mosiyana kwambiri pakuyenda molunjika poyerekeza ndi makhoma akuthwa panjira ya 4.5 km iyi. Zida za generic zimasiya mwachangu madera akuluakulu akufa panjira ya ngalande. Kutaya kutentha koipa m'malo otsekedwa pansi pa nthaka kumapangitsanso kuti ma amplifier amagetsi ogwiritsidwa ntchito ndi ogula aziwonongeka mobwerezabwereza kuti agwire ntchito mosalekeza m'mafakitale.
Chothandizira mafoni chamakono chomwe chimagwiritsidwa ntchito ndi anthu ambiri m'madera akumidzi sichingathe kuthana ndi kutumiza mauthenga kwa nthawi yayitali, kuletsa kusokoneza, komanso kugwira ntchito nthawi zonse. Ichi ndichifukwa chake gulu lathu la mainjiniya linayambitsa njira yosakanikirana ndi ma fiber repeaters komanso ma wireless broadband repeaters ngati njira yayikulu yolimbikitsira ma signal signal.
Titamaliza kufufuza kwathunthu za RF pamalopo, gulu lathu linapanga mapulani a chigawo ndi chigawo cha malo ovuta awa a ngalande yamagetsi. Magulu atatu a zobwerezabwereza za fiber optic adagwira ntchito yokulitsa chizindikiro cha mtunda wautali. Kutsika kwa fiber kumapangitsa kuti chizindikirocho chichepetse kwambiri pamayendedwe olunjika a ngalande oyenda makilomita ambiri.
Tinawonjezera ma repeater atatu opanda zingwe a broadband ophatikizidwa ndi ma antenna ang'onoang'ono a panel. Magawo awa adapereka mipata yolunjika kuzungulira ma curve ndi madera okhala ndi zingwe zamagetsi amphamvu komwe kusokoneza kwa maginito kumakhala kokwera.
Kukhazikitsa mphamvu yonse ya chizindikiro chowonjezera kumagwiritsa ntchito mapangidwe osiyanasiyana a antenna pazigawo zowongoka ndi zigawo zokhota. Ma antenna a directional panel amawongolera ma radiation angles mosamala kuti achepetse kuwunikira ndi kusokoneza kwa chizindikiro cha njira zambiri.
Ogwira ntchito kumunda anamaliza kuyika zida, kuyika chingwe chowonjezera, kukhazikitsa zobwerezabwereza zozungulira, komanso kukonza bwino ma angles a antenna m'masiku asanu okha. Kuyenda pang'onopang'ono kumeneku kunapangitsa kuti pakhale kusiyana pakati pa madera oyandikana nawo komanso kuti ntchito yomanga pamalopo ikhale yochepa.
Mayeso a zida pambuyo pa ntchito adawonetsa kuwerenga kolimba. RSRP idapitilira ‑70 dBm mu utali wonse wa ngalande, pomwe SINR idagwira ntchito bwino kuposa 10 dB. Kuyimba kwa mawu ndi makanema owonera apamwamba sanachite chibwibwi kapena kusiya ntchito kwa makampani onse atatu onyamula ma netiweki.
Ogwira ntchito yokonza minda adasunga kulumikizana kwabwino kwa mafoni nthawi yonse yomwe ankagwira ntchito pansi pa nthaka. Malo ogwirira ntchito ogwira ntchito komanso zida zowunikira zida zidatumiza deta yowunikira ku zipinda zowongolera nthawi yomweyo. Kutumiza kumeneku kunachotsa madontho amdima olumikizirana pansi pa nthaka ndipo kunapanga chithandizo chodalirika cha waya chowunikira gridi ya UHV ndi zochitika zadzidzidzi.
Kuyambira pa compact cell phone booster madera akumidzi mpaka ma industrial fiber repeaters, Lintratek ili ndi R&D yonse mkati ndi mphamvu zopangira kuti ikhale ndi ma signaling ofooka. Ma phone network solution athu amagwirizana ndi mikhalidwe yovuta kwambiri yogwirira ntchito: malo okhala pansi pa nthaka kwa nthawi yayitali, phokoso lamphamvu la ma elekitiromagineti, chinyezi chambiri komanso mpweya wochepa.
Timapereka chithandizo kuyambira pachiyambi mpaka kumapeto kuphatikizapo kufufuza malo, kulemba mapulani, kupereka zida zonse ndi malangizo okhazikitsa. Dongosolo lathu lothandizira ma signal a ma cell signal limagwiritsidwa ntchito kwambiri m'ma tunnel amagetsi, m'makontrakitala amagetsi a boma, m'ma tunnel amigodi ndi m'makontena a zombo zogwirira ntchito zaukadaulo padziko lonse lapansi.
Ngati ndinu kontrakitala wa RF amene akufuna ntchito zomanga nyumba zapansi panthaka kapena wogulitsa zinthu zambiri padziko lonse lapansi amene akufuna zipangizo zolimbikitsira maginito amagetsi a mafakitale, mutha kuwonanso zinthu zathu zonse, kutsitsa ma datasheet am'deralo ndikufunsa za chithandizo cha mapulojekiti kudzera pahttps://www.lintratek.com.
