Kuwedzera Tunnel Nhare Chiratidzo: Lintrate's High-Simba Fiber Optic Repeater Strategy

Mukuvakwa kwe 2.2 km mugwagwa mugero muShenzhen, kuramba kutaurirana mablackspots akatyisidzira kumisa kufambira mberi. Kunyangwe kuchera kwakange kwasvika 1,500 metres, iyo mobile siginecha yakanyangarika kare se400 metres mukati, zvichiita kuti kuwirirana pakati pevashandi kuve kusingaite. Pasina kugadzikana kwekubatanidza, kushuma zuva nezuva, kutarisa kwekuchengetedza, uye kugadzirisa zvinhu kunomira. Panguva iyi yakaoma, muridzi wepurojekiti akatendeukira kuLintrate kuti ape mhinduro yeturnkey iyo yaizovimbisa kusakanganiswa kwenharembozha munzvimbo yese yekushanda.

Tunnel

Ichishandisa ruzivo rwayo rwakakura munharembozha dzenhare, Lintrate yakakurumidza kuunganidza timu yakazvitsaurira yekugadzira-uye-yekutumira. Mushure mekubvunzana kwakadzama nemutengi uye nekuongorora kwakadzama kweiyo saiti geotechnical uye RF mamiriro, timu yakasarudzayakakwirira-simba fiber optic repeater systemsemusana weprojekiti.

Mayedzo ekutanga pane portal yakaratidza kuti sosi yechiratidzo cheSREP kukosha yaive pazasi -100 dBm (apo -90 dBm kana yepamusoro inoreva hunhu hunogamuchirika). Kuti ukunde izvi, mainjiniya eLintrate akachinjira kune antenna-maitiro ekuwedzera kuwedzera kugamuchira, kuve nechokwadi chekuisa yakasimba kune inodzokorora network.

Iyo yakakosha setup inoshandisa mbiri-bhendi, 20 W fiber optic inodzokorora. Iyo Base Unit yaive yakamira pamusuwo wenzira, nepo Remote Unit yaigara 1,500 metres mukati. Iyo 5 dB, 2-nzira inopatsanura yakafambisa chiratidzo chakakwidziridzwa nemuchinjiko-mapanji, ine maantenna mahombe ekudzokera kumashure kuti afukidze mativi ese emugero akavharika.

Zvinoshamisa, vashandi veLintrate vakapedza kuisirwa muzuva rimwe chete, uye nemangwanani akatevera, kuyedzwa kwakasimbisa kutevedza kuzere nezvinodiwa nemutengi. Uku kutendeuka nekukasira hakuna kungogadzirisa kudzima kwenharembozha asiwo kwakaderedza kuvhiringika kuhurongwa hwetunnel, zvichiwana kurumbidzwa kukuru kubva kumuridzi weprojekiti.

Kuratidza kune ramangwana-netiweki, Lintrate yakashandisa dhizaini inochinjika, isina basa inobvumira iyo Remote Unit uye in-tunnel antennas kuti imiswezve sekuenderera mberi kwekuchera. Sezvo mugero unowedzera, zvigadziriso zvepamhepo zvinochengetedza kuvharika, kuve nechokwadi chekuti vashandi vanogara vachiwana nzira dzakavimbika dzekutaurirana.

Indoor Antennas

Nemakore gumi nematatu ehunyanzvi uye kutumira kunze kwenyika kune dzinopfuura 155 nyika,Lintrateis mugadziri anotungamiraof zvekutengesa nharembozha chiratidzo boosters, fiber optic inodzokorora, uye antenna masisitimu. Yedu yakaratidza rekodhi rekodhi mukati meakasiyana mapurojekiti mamiriro anotiita mudiwa akavimbika kune chero mugero kana nharembozha nharembozha dambudziko.
