Ukunyusa iSignali yeSelfowuni yeTunnel: Icebo lokuPhinda iFiber Optic yeLintrate enamandla aphezulu

Ekwakhiweni komjelo omkhulu oziikhilomitha ezingama-2.2 eShenzhen, iindawo ezimnyama zonxibelelwano eziqhubekayo zasongela ukuthintela inkqubela phambili. Nangona ukumbiwa kwakufikelele kwiimitha ezili-1,500, isignali yeselula yanyamalala kwangoko kwiimitha ezingama-400, nto leyo eyenza ukuba ulungelelwaniso phakathi kwabasebenzi lube nzima. Ngaphandle konxibelelwano oluzinzileyo, ingxelo yemihla ngemihla, ukuhlolwa kokhuseleko, kunye nohlaziyo lwezinto ezicwangcisiweyo luyeke. Kweli xesha libalulekileyo, umnini weprojekthi wajika waya kwiLintrate ukuze anike isisombululo esiza kuqinisekisa isignali yeselula engaphazanyiswayo kuyo yonke indawo yokusebenza.

Umjelo

Isebenzisa amava ayo amaninzi kwiziseko zophuhliso lwezonxibelelwano, iLintrate yaqokelela ngokukhawuleza iqela elizinikeleyo loyilo nokusasaza. Emva kokubonisana okunzulu nomthengi kunye nophando olunzulu lweemeko zejografi kunye ne-RF zesiza, iqela lakhetha i-inkqubo yokuphindaphinda i-fiber optic enamandla aphezulunjengomqolo weprojekthi.

Umzobo weSkimu

Uvavanyo lokuqala kwi-portal lubonise ukuba ixabiso le-SREP yesignali yomthombo lalingaphantsi kwe-100 dBm (apho i-90 dBm okanye ngaphezulu ibonisa umgangatho owamkelekileyo). Ukuze boyise oku, iinjineli ze-Lintrate zitshintshele kwi-antenna yesitayile sephaneli ukuze zonyuse inzuzo yokwamkela, ziqinisekisa igalelo eliqinileyo kwinethiwekhi yokuphindaphinda.

i-antenna yangaphandle

Useto oluphambili lwalusebenzisa i-dual-band, i-20 W fiber optic repeater. I-Base Unit yayimi emnyango we-tunnel, ngelixa i-Remote Unit yayimi kwiimitha ezili-1,500 ngaphakathi. I-5 dB, i-2-way splitter yayihambisa isignali eyandisiweyo kwiindlela ezinqamlezileyo, kunye nee-antenna ezinkulu zepaneli ezibuyela umva ukuya kuvala amacala omabini e-tunnel enomngxuma ogqunywe nge-coverage.

Iyunithi Esisiseko yeFiber Optic Repeater

Okumangalisayo kukuba, iqela le-Lintrate ligqibile ukufaka kwimini enye kuphela, kwaye ngentsasa elandelayo, uvavanyo luqinisekisile ukuthotyelwa ngokupheleleyo kweemfuno zokusebenza komthengi. Olu tshintsho lukhawulezileyo aluzange lusombulule kuphela ukucima kwesignali yeselula kodwa lukwanciphise ukuphazamiseka kwishedyuli yetonela, nto leyo eyafumana udumo olukhulu kumnini weprojekthi.

Iyunithi ekude yeFiber Optic Repeater

Ukuze inethiwekhi ikhuseleke kwixesha elizayo, i-Lintrate iqalise uyilo oluguquguqukayo nolungafunekiyo oluvumela i-Remote Unit kunye nee-antenna ezikwi-tunnel ukuba zibekwe kwakhona njengoko ukumba kuqhubeka. Njengoko i-tunnel isanda, ukulungiswa kwe-fly kugcina ukugqunywa okungenamthungo, kuqinisekisa ukuba abasebenzi bahlala befikelela kunxibelelwano oluthembekileyo.

Ii-Antenna zangaphakathi

Ngobuchule beminyaka eli-13 kunye nokuthumela kwamanye amazwe kumazwe angaphezu kwe-155,I-Lintrateis umenzi ophambiliof izikhuseli zesignali zefowuni zorhwebo, iziphindaphindi ze-fiber optic, kunye neenkqubo ze-antenna. Imbali yethu eqinisekisiweyo kwiimeko ezahlukeneyo zeprojekthi isenza sibe liqabane elithembekileyo kuyo nayiphi na imingeni yesignali yeselula yomjelo okanye yesiseko.
