Ndi zaka 14 ndili ndi luso lofooka pakusintha ma signali, ndalankhula ndi makontrakitala ambiri omwe amakumana ndi mavuto osayembekezereka a kulumikizana mkati mwa ngalande. Kuchedwa kosaoneka kumeneku kumachitika kawirikawiri kuposa kugwa kwa nyumba, koma sikutchulidwa kawirikawiri m'mapepala okonzekera zomangamanga.
Sikuti makampani opanga maukonde sakufuna kuyika ndalama. Pamene kufukula kukupitirira, miyala yolimba ya m'mapiri komanso mipanda yolimba ya konkire imapanga chishango cholimba cha maginito. Chizindikiro choyenda chingatsike pansi pa ‑120 dBm, zomwe zikutanthauza kuti "palibe ntchito konse". Ma wailesi oyenda mbali ziwiri amafikanso pamlingo wovuta kupitirira mamita 500, makamaka pafupi ndi makhoma akuthwa. Malo ambiri okhala ndi ngalande amadalirabe kulira, kuthamanga mozungulira, kapena kugwedezeka kwa wailesi kuti gulu ligwirizane mkati mwa gulu.
Ma fiber optic repeater amadziwika bwino ngati njira yodziwika bwino yolumikizirana ndi mafoni pama projekiti opangidwa ndi tunnel. Mfundo yogwirira ntchito ndi yosavuta. Chida chachikulu cholumikizirana ndi ma netiweki chimajambula ma signal a basestation pa tunnel portal, kusintha ma signal a RF kukhala optical data, ndikutumiza kudzera mu fiber cables. Ma remote units mkati mwa tunnels amasintha kuwala kukhala ma radio frequency ndi ma signal owulutsa kudzera mu antennas.
Pali zovuta zingapo zaukadaulo zomwe zimafunabe kusamalidwa mosamala. Ulusi umataya pafupifupi 0.35 dB pa kilomita imodzi, zomwe ndi zabwino kwambiri kuposa ma coaxial feeders omwe amataya oposa 10 dB pa kilomita iliyonse. Zimenezi zimapangitsa kuti fiber hardware ikhale njira yokhayo yothandiza pa ngalande zazitali zofikira 20 km kapena kupitirira apo.
Ubwino wa gwero la chizindikiro pa malo otseguka a ngalande umapanga zotsatira zonse za polojekiti yanu. Ngati mawerengedwe a portal RSRP ali pansi pa ‑100 dBm, mudzafunika ma antenna opereka omwe ali ndi phindu lalikulu kapena ma module ophatikiza magwero ambiri kuti muwonjezere kukhudzidwa kwa kulandira.
Kusokoneza kwa mafunde amadzimadzi kumabweretsa chiopsezo china chenicheni. M'malo opapatiza otsekedwa, ma signal opangidwa ndi ma radiation amatha kubwerera ku hardware yapafupi, kukweza phokoso pansi pa siteshoni yapansi komanso kuyambitsa kutsika kwa siteshoni yapansi. Zipangizo zolimbikitsira ma signal amagetsi a mafakitale ziyenera kukhala ndi ntchito zozindikira ndi kuletsa kugwedezeka.
Kukhala ndi ma network ambiri kumawonjezera zofunikira zina. Ma network osiyanasiyana amayendetsa ma frequency band osiyanasiyana, kotero makina anu olimbikitsira ma signal a m'manja amafunikira zida za wideband kuti zithandizire miyezo yosiyanasiyana ya ma network nthawi imodzi.
Mavuto atatu enieni amachitika nthawi zonse pa ntchito za ngalande, ndipo palibe njira imodzi yokwanira anthu onse. Ngalande iliyonse imafunika kuyesedwa kutengera momwe ilili.
Choyamba chimakhala chovuta kwambiri pamalopo. Chinyezi chochuluka, fumbi lochuluka komanso kutentha kosinthasintha nthawi zambiri kumakhala pansi pa nthaka. Ma ngalande ena osungira madzi ndi mapaipi amasunga chinyezi cha 90% chaka chonse. Zipangizo wamba monga cholimbikitsira mafoni m'madera akumidzi sizigwira ntchito mkati mwa miyezi ingapo. Mukasankha zida za malo otere, tsatirani mfundo zitatu zazikulu: chitetezo champhamvu, nyumba yotenthetsera kutentha kwachitsulo chonse, komanso kutentha kwakukulu. Musasiye chithandizo cha cholumikizira chosalowa madzi, chitetezo cha surge ndi nthaka yoyenera. Zinthu zazing'ono izi zimasankha ngati makina anu amagwira ntchito bwino kwa chaka chimodzi kapena zisanu.
Chachiwiri, njira zazitali zophatikizana ndi mapindidwe akuthwa. Kutayika kwa chizindikiro kumakhala kokhazikika m'magawo owongoka. Mutha kuyika mayunitsi obwerezabwereza akutali mamita 500-800 aliwonse. Makona amasintha chilichonse; mafunde a wailesi sangayende mozungulira mapindidwe m'mizere yowongoka. Mudzafunika mayunitsi obwerezabwereza amphamvu kwambiri ophatikizidwa ndi ma antenna ang'onoang'ono kuti muchepetse kutsika kwa chizindikiro chakuthwa mozungulira ma curve.
Chachitatu, zizindikiro zofooka zolowera pa khomo la ngalande, zomwe ndi vuto lalikulu kwambiri. Ngakhale zida zapamwamba kwambiri za backend zimapereka zotsatira zoyipa ngati chizindikiro cha portal chili pansi pa ‑100 dBm. Mwanjira ina, mutha kusintha magwero a zizindikiro kapena kupempha ogwiritsa ntchito kuti asinthe makonda a siteshoni. Koma malo ambiri ogwirira ntchito sangathandizire kusinthaku. Pazochitika zotere, gulu lanu la mainjiniya liyenera kukonza magwiridwe antchito olandirira kutsogolo. Gwiritsani ntchito ma antenna a donor omwe ali ndi phindu lalikulu limodzi ndi ma module olondola a zosefera kuti muchepetse phokoso la band, ndikuchotsa chizindikiro chomwe chingagwiritsidwe ntchito kuchokera kuzinthu zochepa zomwe zikubwera.
Zochitika zonse zitatuzi zili ndi mfundo imodzi yofunika: choyamba fufuzani bwino malo, kenako gwirizanitsani zida moyenera. Musakakamize zida wamba pa ntchito iliyonse ya ngalande. Mapangidwe okonzedwa mwamakonda nthawi zonse amagwira ntchito bwino.
Kulankhulana kokhazikika kwa ngalande kukusintha mwachangu kuchoka pa chinthu china chowonjezera kupita ku chinthu chofunikira. Malamulo okhwima achitetezo amafuna maulalo odalirika opanda zingwe kuti antchito azigwira ntchito, kuyang'anira nthawi yeniyeni komanso kuyankha mwadzidzidzi. Pakadali pano, njira zogwiritsira ntchito mtsogolo monga kuyendetsa magalimoto pamsewu ndi kuyendetsa galimoto zokha zimadaliranso kulumikizana kwa mafoni pansi pa nthaka nthawi zonse.
Lintratek yapeza luso lambiri pa ntchito zovuta izi. Zipangizo zathu zagwiritsidwa ntchito m'mapulojekiti ofunikira kuphatikiza mizere ya metro, mabungwe ofufuza ndi maofesi apamadzi m'maiko ndi madera 155.
Tasintha kwambiri kuposa kungopanga zida zamagetsi. Timaona malo ochitira zinthu mobisa ngati malo athu oyesera zinthu zenizeni, ndipo magwiridwe antchito odalirika akhala mwayi wathu waukulu wopikisana. Kuyambira cholimbikitsira mafoni am'manja kumadera akumidzi mpaka makina olimbikitsira ma signal a fiber optic, timapereka njira yonse yothetsera mavuto a mafoni: kufufuza malo, kukonza mapulani, kupereka zida zonse ndi malangizo okhazikitsa. Chida chathu cholimbikitsira ma signal amagetsi chimagwirizana ndi njira zoyendetsera ntchito, migodi yamigodi ndi mipanda yapansi panthaka.
Ngati ndinu kampani yopereka ma bid tunnel a RF kapena kampani yogulitsa zinthu zapansi panthaka, kapena kampani yogulitsa zinthu zambiri padziko lonse lapansi yomwe ikufuna zida zokulitsa ma signal a mafakitale, onani kabukhu kathu ka zinthu zonse ndikutsitsa ma datasheet aukadaulo pahttps://www.lintratek.com.
