M'malo otsekeka monga ma tunnel ndi zipinda zapansi, ma siginecha opanda zingwe nthawi zambiri amalepheretsedwa kwambiri, zomwe zimapangitsa kuti zida zoyankhulirana monga mafoni am'manja ndi zida zama netiweki zisamagwire bwino ntchito. Kuti athetse vutoli, mainjiniya apanga zida zosiyanasiyana zokulitsa ma siginecha. Zipangizozi zimatha kulandira ma siginecha opanda zingwe opanda zingwe ndikuwakulitsa, zomwe zimapangitsa kuti zida zopanda zingwe zizigwira ntchito bwino pamalo otsekeka. Pansipa, tikuwonetsa zida zokulirapo zomwe zimagwiritsidwa ntchito m'machubu ndi zipinda zapansi.
1. Dongosolo la Antenna (DAS)
Dongosolo la antenna ndi njira yomwe imagwiritsidwa ntchito nthawi zambiri yokulitsa ma siginecha, yomwe imayambitsa ma sign akunja opanda zingwe m'malo amkati mwa kuyika tinyanga zingapo mkati mwa tunnel ndi zipinda zapansi, kenako ndikukulitsa ndikufalitsa ma siginecha opanda zingwe kudzera mu tinyanga zogawidwa. Dongosolo la DAS limatha kuthandizira ogwiritsa ntchito angapo komanso ma frequency angapo, ndipo ndiloyenera kumayendedwe osiyanasiyana opanda zingwe, kuphatikiza 2G, 3G, 4G, ndi 5G.
2. Pezani mtundu wamakina amplifier
Mtundu wowonjezera wama siginoloji umakwaniritsa kufalikira kwa ma siginecha polandila ndi kukulitsa ma siginecha opanda zingwe opanda zingwe, kenako nkuwatumizanso. Chida chamtunduwu nthawi zambiri chimakhala ndi mlongoti wakunja (kulandira ma siginoloji), chokulitsa chizindikiro, ndi mlongoti wa m'nyumba (zotumizira ma sign). Amplifier yamtundu wa phindu ndiyoyenera zipinda zazing'ono zapansi ndi tunnel.
3. Fiber optic repeater system
Fiber optic regeneration system ndi njira yolumikizira ma siginecha yapamwamba kwambiri yomwe imatembenuza ma siginecha opanda zingwe kukhala ma siginecha owoneka bwino, omwe amatumizidwa mobisa kapena mkati mwa tunnel kudzera mu ulusi wa optical, kenako amasinthidwa kukhala ma siginecha opanda zingwe kudzera pa olandila fiber optic. Ubwino wa dongosololi ndikuti umakhala ndi kutayika kwapang'onopang'ono kwazizindikiro ndipo kumatha kukwaniritsa kufalikira kwautali wautali komanso kufalitsa.
4. Kaselo Kakang'ono
Malo ang'onoang'ono apansi ndi mtundu watsopano wa chipangizo chokulitsa chizindikiro chomwe chili ndi mphamvu yake yoyankhulirana opanda zingwe ndipo chimatha kulankhulana mwachindunji ndi mafoni a m'manja ndi zipangizo zina zopanda zingwe. Masiteshoni ang'onoang'ono nthawi zambiri amaikidwa padenga la tunnel ndi zipinda zapansi, zomwe zimapereka chidziwitso chokhazikika chopanda zingwe.
Zomwe zili pamwambazi ndi zina zomwe zimagwiritsidwa ntchito pamachulukidwe ndi zipinda zapansi. Posankha chipangizo, m'pofunika kuganizira zinthu monga kufunika kwa kuphimba kwenikweni, bajeti, ndi kugwirizanitsa kwa chipangizo kuti musankhe chipangizo choyenera kwambiri.
Nkhani yoyambirira, gwero:www.lintratek.comLintratek foni yam'manja yowonjezera chizindikiro, yopangidwanso iyenera kuwonetsa gwero!
