5ghz yonke i-eriyali
1.1 Inkcazo ye-eriyali yesiKhululo esiSisiseko I-eriyali yesitishi esisisiseko sisidluliseli esiguqula amaza akhokelwayo asasazeke kumgca kunye nesithuba samaza ombane wombane.Yakhiwe kwisikhululo esisisiseko.Umsebenzi wayo kukuhambisa imiqondiso ye-electromagnetic wave okanye ukufumana imiqondiso.1.2 Ukuhlelwa kwee-eriyali zeSikhululo esiSiseko Ii-eriyali zeSikhululo seSiseko zahlulwe zaba zii-eriyali ze-omnidirectional kunye ne-eriyali eyalathiswayo ngokwesikhokelo, kwaye inokwahlulwa ibe zii-eriyali ezinepolarized enye kunye nee-eriyali ezimbini-polarized ngokweempawu zepolarization (i-polarization ye-eriyali ibhekisa kwicala lamandla ombane owenziweyo xa i-eriyali ikhupha. Xa ibala lombane lamandla Xa isalathiso sikwi-perpendicular emhlabeni, i-radio wave ibizwa ngokuba yi-vertical polarized wave;xa ulwalathiso lwamandla ebala lombane lunxusene nomhlaba, iliza likanomathotholo libizwa ngokuba yi-horizontal polarization. Ii-eriyali ezipolarized kabini zipolarized kuzo zozibini izikhombisi ezithe tye nezithe nkqo.Kwaye i-eriyali enye-polarized kuphela tye okanye nkqo).
2.1 Ubume kunye nobungakanani beSikhululo seSikhululo se-Antenna Market Okwangoku, inani lezikhululo ze-4G e-China malunga ne-3.7 yezigidi.Ngokweemfuno zokwenyani zorhwebo kunye neempawu zobugcisa, inani lezikhululo zesiseko ze-5G ziya kuba malunga ne-1.5-2 amaxesha ezikhululo zesiseko se-4G.Inani lezikhululo ze-5G e-China kulindeleke ukuba zifike kwi-5-7 yezigidi, kwaye kulindeleke ukuba i-20-40 yezigidi ze-antennas zesiseko ziya kufuneka kwixesha le-5G.Ngokwengxelo ye-Academia Sinica, ubungakanani bentengiso yee-antenna zesiseko kwilizwe lam buya kufikelela kwi-43 yeebhiliyoni zeeyuan ngo-2021 kunye ne-55.4 yeebhiliyoni zeeyuan ngo-2026, kunye ne-CAGR ye-5.2% ukusuka kwi-2021 ukuya kwi-2026. Ngenxa yokuguquguquka kwemijikelezo ye-antenna yesikhululo kunye nomjikelezo omfutshane wexesha le-4G, ubungakanani bemakethe ye-antenna ekuqaleni kwexesha le-4G kwi-2014 yenyuka kancane. Ukuxhamla kuphuhliso olunamandla lwe-5G, kulindeleke ukuba izinga lokukhula kobungakanani bemarike kulindeleke ukuba linyuke.Kulindeleke ukuba ubungakanani bemarike bufikelele kwi-78.74 yeebhiliyoni zeeyuan ngo-2023, kunye nesantya sokukhula sonyaka esiyi-54.4%.
3.1 Ukufika kwexesha le-5G Ukuqhubela phambili ngokukhawuleza kwe-5G yokuthengisa ngenye yezinto ezibalulekileyo ezikhuthaza ukuphuhliswa kweshishini le-antenna yesikhululo sesikhululo.Umgangatho we-antenna yesiseko sesikhululo sichaphazela ngokuthe ngqo amava omsebenzisi, kunye nokukhuthazwa kwezorhwebo kwe-5G kuya kuba negalelo ngokuthe ngqo ekuphuculeni nasekuphuhliseni ishishini le-antenna yesikhululo.Ekupheleni kuka-2021, iyonke i-1.425 yezigidi zezikhululo ze-5G zakhiwe kwaye zavulwa kwilizwe lam, kunye nenani elipheleleyo lezikhululo ze-5G kwilizwe lam zenza ngaphezu kwe-60% yehlabathi lilonke.Imfuneko yenani le-eriyali yesikhululo sesiseko: Ukunciphisa amandla e-eriyali kuhambelana ngokufanelekileyo nokuphindaphinda kwesignali. Ukunciphisa amandla e-eriyali ye-5G iphezulu kakhulu kunelo le-4G.Ngaphantsi kweemeko ezifanayo, ukugubungela iimpawu ze-5G kuphela kwikota ye-4G.Ukufezekisa indawo efanayo yokugubungela imiqondiso ye-4G, Uyilo olubanzi lwesiseko sesikhululo luyafuneka ukuhlangabezana namandla omqondiso ngaphakathi kwendawo yokhuselo, ngoko ke imfuno ye-eriyali yesiseko iya kwanda kakhulu.
4.1 ITekhnoloji enkulu ye-MIMO Ithekhinoloji ye-MIMO yeyona nto ingundoqo kunxibelelwano lwe-4G.Ngokufakela ii-eriyali ezininzi zokudlulisa kunye nokufumana kwizixhobo zehardware, Iimpawu ezininzi zinokuthunyelwa kwaye zamkelwe phakathi kwee-eriyali ezininzi.Phantsi kobume bemithombo ye-spectrum elinganiselweyo kunye namandla okuhambisa, Ukuphucula umgangatho wokuhanjiswa komqondiso kunye nokwandisa amajelo onxibelelwano. Itekhnoloji enkulu ye-MIMO ye-MIMO enkulu, esekwe kwinkxaso yokuqala ye-MIMO yee-eriyali ezisi-8 kuphela, iphucula ukhuseleko lwenethiwekhi kunye nozinzo ngokongeza ii-eriyali ezininzi ukwenza izixhobo zobungakanani bomhlaba kunye nokwandisa umthamo wenkqubo. Itekhnoloji enkulu ye-MIMO ibeka iimfuno eziphezulu kwii-eriyali zesikhululo.Itekhnoloji enkulu ye-MIMO ifuna ukufakelwa kwenani elikhulu lee-eriyali ezibekwe zodwa kwindawo enyiniweyo yesixhobo ukuqinisekisa inzuzo kunye nokuchaneka okufunekayo ekwenzeni ukukhanya. Le teknoloji idinga ukuba i-antenna kufuneka ibe yi-miniaturized, kunye neyodwa ephezulu kunye nezinye iimpawu.Okwangoku, itekhnoloji ye-eriyali ye-Massive MIMO ikakhulu yamkela isisombululo se-64-channel.Itekhnoloji ye-4.2 mmWave Ngenxa yeempawu zomgama omfutshane wokusasaza kunye nokunciphisa kakhulu amaza e-5G millimeter, Uyilo lwesikhululo esishinyeneyo kunye netekhnoloji enkulu yoluhlu lwe-antenna inokuqinisekisa umgangatho wothumelo, kunye nenani lee-eriyali zesikhululo esinye sesiseko siya kufikelela kumashumi okanye amakhulu.I-eriyali yesiqhelo ayisebenzi kuba ilahleko yokuhanjiswa komqondiso inkulu kakhulu kwaye umqondiso awukwazi ukuhanjiswa kakuhle.
