Lokhu kungenxa yokuthi amadivaysi e-5G asebenzisa amabhendi ahlukene emvamisa ephezulu ukuze afinyelele ukudluliswa kwedatha ngesivinini esikhulu, okuholela esidingweni nobunkimbinkimbi bamamojula angaphambili we-5G RF, futhi isivinini besingalindelekile.
Inkimbinkimbi iqhuba ukuthuthuka okusheshayo kwemakethe yemojula ye-RF
Lo mkhuba uqinisekiswa idatha yezikhungo eziningana zokuhlaziya.Ngokwesibikezelo sikaGartner, imakethe ye-RF front-end izofinyelela ama-US $ 21 billion ngo-2026, nge-CAGR ka-8.3% kusukela ngo-2019 kuya ku-2026;Isibikezelo sika-Yole sinethemba elikhulu.Balinganisela ukuthi usayizi wemakethe ophelele we-RF front-end uzofinyelela kuma-dollar ayizigidi eziyizinkulungwane ezingama-25.8 ngo-2025. Phakathi kwabo, imakethe yamamojula e-RF izofinyelela ku-17.7 billion wamadola aseMelika, okubalelwa ku-68% wesamba semakethe, ngokukhula okuhlanganisiwe konyaka. isilinganiso esingu-8%;Isilinganiso samadivayisi ahlukahlukene sasingama-US $ 8.1 billion, sibalwa ama-32% esikali semakethe esiphelele, ne-CAGR ka-9%.
Uma kuqhathaniswa nama-chips e-multimode okuqala e-4G, singaluzwa futhi lolu shintsho ngendlela enembile.
Ngaleso sikhathi, i-chip ye-multimode ye-4G yayihlanganisa kuphela amabhendi angama-16, akhuphuke afinyelela ku-49 ngemva kokungena enkathini ye-all-netcom yomhlaba wonke, futhi inani le-3GPP lenyuke laya ku-71 ngemva kokwengeza ibhendi yefrikhwensi engu-600MHz.Uma i-5G millimeter wave frequency band icatshangelwa futhi, inani lamabhendi emvamisa lizokhula nakakhulu;Okufanayo kuyiqiniso ngobuchwepheshe bokuhlanganisa inkampani yenethiwekhi - ngenkathi ukuhlanganisa inkampani yenethiwekhi isanda kwethulwa ngo-2015, bekukhona izinhlanganisela ezingaba ngu-200;Ngo-2017, kwakukhona isidingo sama-frequency bands angaphezu kuka-1000;Esigabeni sokuqala sokuthuthukiswa kwe-5G, inani lenhlanganisela ye-frequency band lidlule i-10000.
Kodwa akulona nje inani lamadivayisi ashintshile.Kuzinhlelo zokusebenza ezingokoqobo, ukuthatha isistimu yegagasi ye-5G millimeter esebenza ku-28GHz, 39GHz noma 60GHz ibhendi yefrikhwensi njengesibonelo, esinye sezithiyo ezinkulu ebhekene nazo ukuthi zinganqoba kanjani izici ezingathandeki zokusakaza.Ngaphezu kwalokho, ukuguqulwa kwedatha ye-broadband, ukuguqulwa kwe-spectrum esebenza kahle kakhulu, idizayini yokunikeza amandla isilinganiso sokusebenza kahle kwamandla, ubuchwepheshe bokupakisha obuthuthukisiwe, ukuhlolwa kwe-OTA, ukulinganiswa kwezintili, njll., konke kuhlanganisa ubunzima bomklamo obubhekene nesistimu yokufinyelela ye-millimeter wave band 5G.Kungabikezelwa ukuthi ngaphandle kokuthuthukiswa kokusebenza kwe-RF okuhle kakhulu, akunakwenzeka ukuklama amatheminali e-5G ngokusebenza okuhle kakhulu kokuxhuma nokuphila okuqinile.
Kungani i-RF front-end iyinkimbinkimbi kangaka?
I-RF front-end iqala othini, idlule ku-transceiver ye-RF futhi iphelele kumodemu.Ngaphezu kwalokho, kunobuchwepheshe obuningi be-RF obusetshenziswa phakathi kwama-antenna namamodemu.Umfanekiso ongezansi ubonisa izingxenye ze-RF front-end.Kubanikeli balezi zingxenye, i-5G ihlinzeka ngethuba elihle lokwandisa imakethe, ngoba ukukhula kokuqukethwe kwe-RF front-end kuhambisana nokwanda kobunzima be-RF.
Iqiniso elingenakuzitshwa ukuthi idizayini ye-RF front-end ayikwazi ukunwetshwa ngokuhambisana nesidingo esandayo se-wireless yeselula.Ngenxa yokuthi i-spectrum iyinsiza eyivelakancane, amanethiwekhi amaningi weselula namuhla awakwazi ukuhlangabezana nesidingo esilindelekile se-5G, ngakho abaklami be-RF badinga ukuzuza ukusekelwa okungakaze kubonwe kwenhlanganisela ye-RF kumadivayisi abathengi futhi bakhe imiklamo yamaselula engenawaya ehambisana kahle kakhulu.
Kusukela ku-Sub-6GHz ukuya kumagagasi amamilimitha, wonke ama-spectrum atholakalayo kufanele asetshenziswe futhi asekelwe ekwakhiweni kwakamuva kwe-RF ne-antenna.Ngenxa yokungaguquguquki kwezinsiza ze-spectrum, kokubili imisebenzi ye-FDD ne-TDD kufanele ihlanganiswe kumklamo we-RF front-end.Ukwengeza, ukuhlanganiswa kwenkampani yenethiwekhi kukhulisa umkhawulokudonsa wepayipi elibonakalayo ngokubopha i-spectrum yamafrikhwensi ahlukene, okuphinda kukhulise izidingo nobunkimbinkimbi be-RF front-end.
