Ngokuthuthuka kobuchwepheshe, ukuthembela kwethu ezimpawini ezingenantambo kuyanda. Kodwa-ke, ezindaweni ezithile ezithile, njengezindlu ezingaphansi komhlaba, izimpawini ezingenantambo zivame ukuphazamiseka kakhulu, okuthinta ukusetshenziswa okuvamile. Ngakho-ke, ubuchwepheshe bokukhulisa izimpawini ezingaphansi komhlaba buvele. Okulandelayo, sizohlola isimiso sokusebenza, ukusetshenziswa, kanye nokubaluleka kokukhulisa izimpawini ezingaphansi komhlaba ekuxhumaneni kwanamuhla.
1, Isimiso sokusebenza sokukhulisa isignali engaphansi komhlaba
1.1 Ukwakheka kwemishini
I-amplifier yesignali engaphansi komhlaba ikakhulukazi inezingxenye ezintathu: i-antenna, i-amplifier, kanye nomsabalalisi wesignali. Lezi zingxenye ezintathu zisebenza ndawonye ukuze kufezwe ukudluliselwa okuphumelelayo kwesignali engenantambo ezindaweni ezingaphansi komhlaba.
1.2 Inqubo yomsebenzi
I-amplifier yesignali iqala ithole amasignali angenantambo abuthakathaka avela ku-antenna, bese ithuthukisa amandla esignali nge-amplifier, bese isabalalisa isignali eqinisiwe ezindaweni ezahlukene zesisekelo ngomsabalalisi wesignali ukuze kufezwe ukuxhumana okungenantambo okuzinzile.
2, Ukusetshenziswa kokukhulisa isignali engaphansi
2.1 Ukusetshenziswa ezakhiweni zokuhlala nezebhizinisi
Ezakhiweni eziningi zokuhlala nezebhizinisi, izindlu zangaphansi zivame ukusetshenziswa njengezindawo zokupaka, amagumbi okugcina izinto, noma izindawo zamahhovisi. Kulezi zindawo, ukushelela kwezimpawu ezingenantambo kubaluleke kakhulu. Ama-amplifier esignali adlala indima ebalulekile kulezi zimo zohlelo lokusebenza.
2.2 Isicelo Ezindaweni Zomphakathi
Ezindaweni zomphakathi ezifana neziteshi zesitimela esingaphansi komhlaba kanye nezindawo zokuthenga ezingaphansi komhlaba, kunesidingo esikhulu samasignali angenantambo ngenxa yokugeleza kwabantu abaningi. I-amplifier yesignali engaphansi komhlaba ingathuthukisa ngempumelelo ukumbozwa kwesignali kanye nekhwalithi kulezi zindawo.
isiphetho
Sekukonke, ubuchwepheshe bokukhulisa isignali yesisekelo buyithuluzi elibalulekile lokuxazulula izinkinga zokuxhumana ezindaweni ezingaphansi komhlaba. Ngokuqonda nokuqonda kahle isimiso sokusebenza kanye nokusetshenziswa kokukhulisa isignali yesisekelo, singazixazulula kangcono izinkinga zokuxhumana ezindaweni ezingaphansi komhlaba futhi sithuthukise ikhwalithi kanye nokusebenza kahle kokuxhumana okungenantambo. Esikhathini esizayo, ngokuthuthuka kobuchwepheshe, sinesizathu sokukholelwa ukuthi ubuchwepheshe bokukhulisa isignali yesisekelo buzoba nokusungula izinto ezintsha kanye nezinhlelo zokusebenza ezengeziwe, okuzoletha ukulula okwengeziwe ezimpilweni zethu nasemsebenzini wethu.
