Uvela phi umqondiso weSelfowuni?

Q1. Uvela phi uphawu lwefowuni ephathwayo?
Ndiyakholelwa ukuba baninzi abantu abavileyo ngala magama mabiniisikhululo esisezantsi okanye isikhululo somqondiso (inqaba), kodwa eneneni bayinto enye. Isignali yefowuni ephathwayo ihanjiswa ngale nto esiyibiza ngokuba sisikhululo sesiseko.

Q2. Yintoni i-electromagnetic wave?
Ukuyibeka ngokulula, amaza e-electromagnetic ngamaza amasuntswana ajikelezayo athatyathwe kwaye akhutshwa esithubeni ngamaza ombane kunye nemagnethi akwisigaba kunye ne-perpendicular enye kwenye. Ziimimandla ye-electromagnetic esasaza ngohlobo lwamaza kwaye inobumbini besuntswana lamaza. Isantya sosasazo: isantya senqanaba lokukhanya, akukho ndlela yokusasaza efunekayo (Izandi zesandi zidinga indawo ephakathi). Amaza ombane afunxwa kwaye abonakale xa edibana nentsimbi, kwaye aye abe buthathaka xa evalwe zizakhiwo, kwaye abe buthathaka xa kunomoya, imvula kunye neendudumo. Okukhona ubude beza bufutshane kunye nokuphakama kwamaza ombane, kokukhona ukuhanjiswa kwedatha ngexesha leyunithi nganye.

Q3. Singawenza njani umqondiso ngokupheleleyo?
Kukho iindlela ezimbini ngoku. Enye kukwazisa umqhubi wakho ukuba isignali yendawo ayilungile, kwaye isebe lokuphucula inethiwekhi liya kuvavanya amandla omqondiso. Ukuba amandla omqondiso akahlangabezani neemfuno, umqhubi uya kwakha isikhululo esisisiseko apha ukuphucula inethiwekhi yakho.

Enye kukusebenzisa isandisi-lizwi sefowuni ephathwayo. Umgaqo wayo kukusebenzisa i-antenna yangaphambili (i-antenna yomxhasi) ukufumana isiginali ye-downlink yesikhululo sesiseko kwisiphindaphinda, ukukhulisa umqondiso oluncedo ngesandisi-lizwi esiphantsi, ukucinezela umqondiso wengxolo kwisiginali, kwaye uphucule isiginali-kuya. -Umlinganiselo wengxolo (S/N); emva koko iguqulelwe phantsi ukuya kwisiginali yefrikhwensi ephakathi, ihluzwe sisihluzo, ikhuliswe ngamaza omoya aphakathi, emva koko itshintshelwe phezulu kwaye iguqulelwe kumaza onomathotholo, ikhuliswe sisikhulisi samandla, kwaye idluliselwe kwisikhululo esiphathwayo ngasemva. i-eriyali (i-eriyali yokubuyisela kwakhona); Kwangaxeshanye, isiginali ye-uplink yesikhululo esihambayo ifunyanwa yi-antenna yangasemva, kwaye icutshungulwe ngekhonkco lokukhulisa i-uplink ecaleni kwendlela echaseneyo: oko kukuthi, idluliselwe kwisikhululo esisezantsi ngesandisi-sandi esisezantsi, ezantsi. -converter, filter, an intermediate amplifier, i-up-converter, kunye ne-amplifier yamandla, ngaloo ndlela Ukuphumelela unxibelelwano lweendlela ezimbini phakathi kwesikhululo sesiseko kunye nesikhululo esihambayo.

Izandisi zesandisi sefowuni eziphathwayo zinokusetyenziswa kwiindawo ezixineneyo zasezidolophini, kwimida yasezidolophini nakwiindawo ezisemaphandleni. Iluncedo kakhulu. Loluphi ukhetho olukhethayo?

I-Linchuang lishishini lobuchwepheshe obuphezulu elisebenzela abasebenzisi abangaphezu kwesigidi esi-1 kumazwe angama-155 nakwimimandla yehlabathi jikelele. Kwinkalo yonxibelelwano oluphathwayo, sigxininisa ekuveliseni izinto ezintsha malunga neemfuno zabathengi ukunceda abathengi ukusombulula iimfuno zomqondiso wonxibelelwano! U-Linchuang uzibophelele ekubeni yinkokeli kushishino olubuthathaka lwe-bridging, ukuze kungabikho ndawo zingaboniyo emhlabeni, kwaye wonke umntu unokunxibelelana ngaphandle kwemiqobo!
