Ungakufinyelela kanjaniukumbozwa kwesiginali yomkhumbi, isiginali ephelele kwikhabethe?
Umkhumbi wokusekelwa kawoyela waphesheya kwezilwandle, izinkathi ezinde ukusuka emhlabathini futhi ujule olwandle. Into ebaluleke kakhulu ukuthi azikho amasiginali emkhunjini, azikwazi ukuxhumana nemindeni yazo, edala ukuphazamiseka empilweni yabasebenzi!
1.details yephrojekthi
Le phrojekthi ukumboza isiginali yemikhumbi yokusekelwa kawoyela yaphesheya kwezilwandle, ingqikithi yemikhumbi emi-2, ngayinye inama-decks ama-4. Imikhumbi yokusekela kawoyela yaphesheya kwezilwandle yimikhumbi ezinikelekile yokuhlola i-Offwore kawoyela kanye negesi, ukuthuthukiswa, kanye nokukhiqizwa, ngokuvamile kude nomhlaba nasekujuleni kolwandle. Ngenxa yendawo yokusebenza nesakhiwo esikhethekile, kuvame ukungabi nasiginali kwikhabethe, futhi izimpilo ze-Crew ziphazamisa kakhulu.
Umuntu ophethe iphrojekthi uthe: Isiginali ekhishini libi kakhulu, akukho sibonakaliso lapho ukusebenza kolwandle kuvamile, kepha akukho sibonakaliso lapho kusatshalaliswa khona, futhi ngithemba ukuxazulula inkinga yamanethiwekhi amathathu.
Isikimu se-2.Design
Indawo yokuhlanganisa isiginali yi-Cabin Corridor, i-Corridor of 4 Phansi imamitha amabili, futhi imikhumbi emibili icishe ibe ngamakhilomitha.
I-3.Product collecconuC SUCEME
Ngokusetshenziswa kwekhabethe engqondweni,Isiginali AmplifierKwakhethwa i-KW35A. I-KW35A inomzimba wensimbi ongenamanzi futhi umswakama, ukudicilela phansi okusebenzayo, kufanelekile ngokwengeziwe izisekelo, imigudu, iziqhingi, amakhabethe nezinye izigcawu eziyinkimbinkimbi. I-antenna enkulu ye-antenna nensimbi yensimbi ye-antenna yensimbi yakhethwa ukuthola izimpondo, ezazifaka esikhundleni. Kwakusetshenziswa i-antenna enkulu lapho umkhumbi uhleliwe, futhiI-Omnidirectional Antennayathathelwa indawo lapho ihamba ngomkhumbi.
4.Ukufaka Kanjani?
Isinyathelo sokuqala, faka i-antenna yangaphandle etholayo: I-antenna etholayo ifakwe endaweni ephezulu yomkhumbi, futhi i-antenna yensimbi yepulasitiki engathola isiginali engu-360 °, efanele ukusetshenziswa olwandle; I-Logarithmic Antenna inokulinganiselwa okukhohlisayo, kepha umphumela wokuthola ungcono, futhi kufanelekile ukusetshenziswa lapho imikhumbi idonswa kabusha ukuze ivuselele kabusha.
Isinyathelo sesibili, ukufakwa kwe-antenna yangaphakathi
I-wiring nokufakwa kwe-antenna yophahla kwikhabethe.
Isinyathelo sesithathu, thintana ne-Signal Repeater.
Bheka ukuthi ukutholwa nokudlulisela izimpondo ezifakiwe ngaphambi kokuzixhumanisa nomgcini. Ngaphandle kwalokho, umgcini angalimala.
Isinyathelo sokugcina, hlola isinali.
Ngemuva kokufakwa, isoftware ye- "CellularZ" yaphinde yasetshenziswa futhi ukuthola inani lesiginali yekhabethe, futhi inani le-RSRP lenyuswe lisuka ku -115dbm liye ku -89dbm, umphumela wokumboza wawunamandla kakhulu!
Ngaphambi kokufaka ngemuva kokufakwa
(I-RSRP yinani elijwayelekile lokulinganisa ukuthi ngabe isinali libushelelezi, ngokuvamile likhuluma, libushelelezi kakhulu ngaphezulu -80dbm, futhi empeleni alikho inethiwekhi engezansi -110dbm).
