Kev lag luam qis qis qis (LNB) tau muaj kev nce siab ntxiv hauv kev lag luam khoom siv hluav taws xob. Raws li Kev Tshawb Fawb Kev Ua Lag Luam, LNB kev ua lag luam muaj nqis txog $ 1.5 nphom hauv 2022 thiab tau kwv yees kom ncav cuag $ 2.3 nphom los ntawm 2030. Qhov kev loj hlob no yog tsav los ntawm kev xav tau ntau ntxiv rau cov ntsiab lus siab thiab nthuav dav ntawm Direct-to-Home (DTH) cov kev pabcuam. Lub International Telecommunication Union (ITU) kwv yees tias kev xa xov tooj cua thoob ntiaj teb yuav tshaj 350 lab los ntawm 2025, qhia txog qhov muaj peev xwm zoo rau LNBs hauv xyoo tom ntej.
Kev nce qib thev naus laus zis yog tus tsav tsheb loj tom qab LNB kev lag luam kev loj hlob. Cov tuam txhab tseem niaj hnub txhim kho LNBs kom tau raws li cov kev xav tau hloov zuj zus ntawm kev lag luam khoom siv hluav taws xob. Piv txwv li, Diodes tsis ntev los no tau tshaj tawm cov khoom siv hluav taws xob qis, lub suab qis LNB lub zog tswj thiab tswj ICs. Cov ICs no yog tsim los rau ntau yam khoom, suav nrog cov thawv teeb saum toj kawg nkaus, TVs nrog cov satellite tuners built-in, thiab computer satellite tuner cards. Lawv muab kev txhim kho kev ua tau zoo thiab kev ntseeg siab, uas yog qhov tseem ceeb rau cov khoom siv hluav taws xob niaj hnub no.
LNB kev ua lag luam yog tus cwj pwm los ntawm ntau yam khoom lag luam catering rau cov neeg siv khoom sib txawv. Cov no suav nrog ib leeg, dual, thiab quad LNBs. Txhua hom yog tsim los ua kom tau raws li cov kev xav tau tshwj xeeb, xws li teeb liab lub zog thiab ntau zaus. Qhov kev sib txawv no tso cai rau cov tuam txhab muab cov kev daws teeb meem rau ntau yam kev siv, los ntawm thaj chaw satellite TV mus rau kev lag luam satellite kev sib txuas lus.
Hauv cheeb tsam, LNB kev ua lag luam kuj pom muaj kev hloov pauv hloov pauv. North America tam sim no muaj kev loj hlob siab tshaj plaws. Txawm li cas los xij, kev lag luam tawm tshiab hauv Asia thiab lwm thaj chaw kuj tseem pom muaj peev xwm tseem ceeb. Kev loj hlob nyob rau hauv cov cheeb tsam no yog tsav los ntawm kev nce satellite tais diav thiab kev saws me nyuam ntawm kev sib txuas lus satellite tshaj plaws.
Ntau lub tuam txhab tswj hwm LNB kev ua lag luam. Microelectronics Technology Inc. (MTI), Zhejiang Shengyang, thiab Norsat yog cov neeg ua si saum toj kawg nkaus. Cov tuam txhab no muaj ntau yam LNB cov khoom lag luam thiab tab tom nqis peev hauv kev tshawb fawb thiab kev txhim kho kom nyob ua ntej hauv kev sib tw toj roob hauv pes. Piv txwv li MTI, tsim thiab muag ntau yam khoom siv microwave IC rau satellite tshaj tawm, kev sib txuas lus, thiab kev sib txuas lus.
Saib tom ntej, LNB kev ua lag luam tau npaj rau kev nthuav dav ntxiv. Kev koom ua ke ntawm IoT thiab 5G kev sib txuas yuav tsum tsim kom muaj lub sijhawm tshiab rau LNBs hauv kev lag luam khoom siv hluav taws xob. Raws li kev siv tshuab satellite txuas ntxiv mus, qhov kev thov rau LNBs ua haujlwm siab yuav zoo li nce ntxiv. Qhov no yuav tsav cov tuam txhab tsim kho tshiab thiab txhim kho LNB cov kev daws teeb meem zoo dua thiab txhim khu kev qha.
