Ndineminyaka elishumi elinesine ndixhasa abafaki beRF kunye namaqabane ehlabathi ngokuthengisa ngobuninzi, ndibone ii-tunnels ezinde ezingaphantsi komhlaba zizisa eminye yemingeni enzima yokugubungela amaqela obunjineli. Le projekthi yokwenyani evela eYibin, eMzantsi-ntshona weTshayina, ibonisa indlela isisombululo senethiwekhi yeselula esilungiselelweyo esisombulula ngayo iimfuno ezinzima zoqhagamshelo ngaphakathi kweziseko zophuhliso zamandla ezibalulekileyo.
Le tunnel iyinxalenye ebalulekileyo exhasa iprojekthi enkulu yamandla eSichuan-Chongqing UHV ethumela umbane ofikelela kwi-35 yeebhiliyoni zeerandi ngonyaka. Lonke eli cala libanzi kangangeekhilomitha ezi-4.5, lahlulwe laba candelo lendlela yaseyunivesithi eliyi-2 km kunye necandelo lendlela yaseChangcui eliyi-2.5 km.
Amaqela eprojekthi ayefuna ukugubungela ngokupheleleyo i-4G kubasebenzi abathathu beenkonzo zonxibelelwano zasekuhlaleni. Amakhonkco eselula anokuthenjwa ayengenakuxoxiswana ngawo ukuze kusetyenziswe umsebenzi wokujikeleza rhoqo kunye nokuphendula ngexesha likaxakeka ngexesha langempela nzulu phantsi komhlaba.
Le ndlela inde evalekileyo, egqunywe kwiimitha ezili-15 ngaphantsi komhlaba, ibangela imiqobo emininzi enzima yobuchwephesha. Iintambo zamandla ezixineneyo ezisebenza ngamandla aphezulu ngaphakathi zenza ingxolo enkulu ye-electromagnetic ebangela lula ukufiphaza kwesignali kunye nokungakhawulezi kwenethiwekhi.
Ukulahleka kwesignali kuziphatha ngendlela eyahlukileyo kakhulu kwiindawo ezithe tye xa kuthelekiswa neendawo ezigobileyo kulo mzila we-4.5 km. Izixhobo eziqhelekileyo zishiya ngokukhawuleza iindawo ezinkulu ezifileyo ecaleni kwendlela yetonela. Ukungasasazeki kakuhle kobushushu kwiindawo ezingaphantsi komhlaba ezivaliweyo kwenza ukuba ii-amplifiers zomgangatho wabathengi ziqhekeke rhoqo kakhulu ukuze ziqhubeke nokusebenza kwimizi-mveliso.
Isincedisi sefowuni esisetyenziswa ngabathengi kwiindawo zasemaphandleni asinakukwazi ukusingatha uthumelo olude, ukusebenza okuchasene nokuphazamiseka, kunye nokusebenza rhoqo ngexesha elinye. Yiyo loo nto iqela lethu lobunjineli liqalise inkqubo exutyiweyo kunye neziphindaphindo zefayibha kunye neziphindaphindo ze-broadband ezingenazingcingo njengenkqubo yokukhuthaza isignali yeselula.
Emva kokugqiba uphando olupheleleyo lwe-RF kwindawo, iqela lethu lenze umzobo weendawo ngeendawo ezihlukeneyo kule ndawo inzima yombane. Iiseti ezintathu zee-fiber optic repeaters ziphathe ulwandiso lwesignali yomgama omde. I-fiber cascading yenza ukunciphisa isignali enzima kwiindlela zokuhamba kwe-tunnel ezithe tye zeekhilomitha ezininzi.
Sidibanise ii-repeaters ezintathu ze-wireless broadband ezidityaniswe nee-antenna zepaneli ezincinci. Ezi yunithi zinikezele ngokuzaliswa kwezithuba ezijoliswe kuzo ezijikeleze ii-curves kunye neendawo ezigcwele iintambo ze-voltage ephezulu apho ukuphazamiseka kwe-electromagnetic kuhlala kuphezulu.
Useto lwe-full power signal booster lusebenzisa ulwakhiwo olwahlukeneyo lwe-antenna kwiindawo ezithe tye kunye neendawo ezigobileyo. Ii-antenna zepaneli ezilawula i-directional panel zilawula ii-engile zemitha ngononophelo ukuze zinciphise ukubonakaliswa kwesignali yeendlela ezininzi kunye nokuphazamiseka.
Abasebenzi basentsimini bagqibile ukufaka izixhobo, ukubeka iintambo ze-feeder, ukufaka i-curved zone repeater, kunye nokulungisa kakuhle ii-engile ze-antenna tilt kwiintsuku ezintlanu kuphela. Olu hambo lwenziwe ngezigaba lwenza ukuba kubekho ukwahlukana okungenamthungo phakathi kweendawo zokugubungela ezikufutshane kwaye kwagcina imijikelo yokwakha kwindawo imfutshane.
Uvavanyo lwezixhobo emva kwekhomishini lubonise ukufundwa okuqinileyo. I-RSRP ihlale ngaphezulu kwe-‑70 dBm kubude betonela yonke, ngelixa i-SINR ibambe izinzile ngaphezulu kwe-10 dB. Iifowuni zelizwi kunye neevidiyo zokuhlola ezikumgangatho ophezulu zazisebenza ngaphandle kokugungqa okanye ukuhla kuzo zonke iinkampani ezintathu zenethiwekhi.
Abasebenzi bokulungisa intsimi bagcina unxibelelwano oluzinzileyo oluhambayo lonke ixesha besebenza phantsi komhlaba. Indawo yokusebenza kwabasebenzi kunye nezixhobo zokubeka esweni izixhobo zithumele idatha yokubeka esweni kumagumbi olawulo ngaphandle kokulibazisa. Olu lungiselelo lususe amabala amnyama onxibelelwano olungaphantsi komhlaba kwaye lwakha inkxaso ethembekileyo engenazingcingo yokuhlolwa kwegridi ye-UHV kunye neziganeko zongxamiseko.
Ukususela kwi-compact cell phone booster kwiindawo zasemaphandleni ukuya kwi-heavy-duty industrial fiber repeaters, i-Lintratek igcina uphando olupheleleyo lwangaphakathi kunye nophuhliso kunye nomthamo wokuvelisa ukuze kugqunywe isignali ebuthathaka. Ipotifoliyo yethu yesisombululo senethiwekhi yeselula ihambelana neemeko zokusebenza ezinzima: iindawo ezingaphantsi komhlaba ezivalekileyo ixesha elide, ingxolo enamandla ye-electromagnetic, ukufuma okuphezulu kunye nomoya ophantsi.
Sinikezela ngenkonzo ukususela ekuqaleni ukuya ekupheleni kuquka uphando lwesiza, uyilo loyilo olwenziwe ngokwezifiso, ukubonelela ngezixhobo ezipheleleyo kunye nesikhokelo sokufakela. Inkqubo yethu yokunyusa isignali yeselula yomgangatho weshishini isebenza ngokubanzi kwiitonela zombane, iipaseji zombane zikamasipala, iitonela zemigodi kunye neendawo zeenqanawa zeethenda zobunjineli kwihlabathi liphela.
Ukuba ungumkontrakta we-RF obhida imisebenzi yeziseko zophuhliso ezingaphantsi komhlaba okanye umthengisi wehlabathi jikelele ofumana izixhobo zokunyusa isignali yamandla ekumgangatho wemizi-mveliso kwiiprojekthi zoncedo, ungajonga imveliso yethu epheleleyo, ukhuphele amaphepha edatha engingqi kwaye ubuze ngenkxaso yeprojekthi eyenziwe ngokwezifiso ngokusebenzisahttps://www.lintratek.com.
