Imarike yeLow Noise Block (LNB) ijongene nokunyuka okukhulu kwishishini le-elektroniki labathengi. NgokweeNgxelo zeMarike eziQinisekisiweyo, imarike ye-LNB yayixabisa i-$1.5 yeebhiliyoni ngo-2022 kwaye kulindeleke ukuba ifikelele kwi-$2.3 yeebhiliyoni ngo-2030. Olu kukhula luqhutywa kukwanda kwemfuno yomxholo ocacileyo kunye nokwandiswa kweenkonzo ze-Direct-to-Home (DTH). I-International Telecommunication Union (ITU) iqikelela ukuba ubhaliso lwesathelayithi lwehlabathi luya kudlula kwi-350 yezigidi ngo-2025, nto leyo ebonisa amandla aqinileyo e-LNB kwiminyaka ezayo.
Uphuhliso lwetekhnoloji luyimbangela enkulu yokukhula kwemarike ye-LNB. Iinkampani ziqhubeka nokuphucula ii-LNB ukuze zihlangabezane neemfuno eziguqukayo zoshishino lwe-elektroniki lwabathengi. Umzekelo, iDiodes isandula ukuqalisa uthotho lwee-IC zolawulo lwamandla ze-LNB ezinamandla aphantsi, ezingenangxolo iphantsi. Ezi IC zenzelwe iimveliso ezahlukeneyo, kubandakanya iibhokisi ze-set-top, oomabonakude abanee-tuner zesathelayithi ezakhelwe ngaphakathi, kunye namakhadi e-tuner yesathelayithi yekhompyutha. Zibonelela ngokusebenza kakuhle nokuthembeka okuphuculweyo, okubalulekileyo kwii-elektroniki zabathengi banamhlanje.
Imakethi ye-LNB iphawulwa ziintlobo ngeentlobo zeemveliso ezihlangabezana neemfuno ezahlukeneyo zabasebenzisi. Ezi ziquka ii-LNB ezi-single, ezi-dual, nezi-quad. Uhlobo ngalunye luyilelwe ukuhlangabezana neemfuno ezithile, ezinje ngamandla esignali kunye nobubanzi befrikhwensi. Olu hluka luvumela abavelisi ukuba banikezele ngezisombululo ezenzelwe bona kwiintlobo ngeentlobo zezicelo, ukusuka kwiTV yesathelayithi yokuhlala ukuya kunxibelelwano lwesathelayithi yorhwebo.
Ngokwengingqi, imakethi ye-LNB ikwabona utshintsho olukhulu. UMntla Melika okwangoku ujongene nesantya esiphezulu sokukhula. Nangona kunjalo, iimakethi ezisakhulayo e-Asia nakwezinye iindawo nazo zibonisa amandla amakhulu. Ukukhula kwezi ndawo kuqhutywa kukwanda kokufakwa kwezitya zesathelayithi kunye nokwamkelwa kobuchwepheshe obuphambili bonxibelelwano lwesathelayithi.
Iinkampani ezininzi zilawula imarike ye-LNB. I-Microelectronics Technology Inc. (MTI), iZhejiang Shengyang, kunye neNorsat ziphakathi kwabadlali abaphambili. Ezi nkampani zibonelela ngoluhlu olubanzi lweemveliso ze-LNB kwaye zihlala zityala imali kuphando nakuphuhliso ukuze zihlale ziphambili kumhlaba wokhuphiswano. I-MTI, umzekelo, ivelisa kwaye ithengisa iintlobo ngeentlobo zeemveliso ze-microwave IC zokusasaza ngesathelayithi, unxibelelwano, kunye nonxibelelwano.
Ukujonga phambili, imakethi ye-LNB ikulungele ukwanda ngakumbi. Ukuhlanganiswa konxibelelwano lwe-IoT kunye ne-5G kulindeleke ukuba kudale amathuba amatsha kwi-LNB kwishishini le-elektroniki yabathengi. Njengoko itekhnoloji yesathelayithi iqhubeka ihambela phambili, imfuno ye-LNBs esebenza kakuhle iya kwanda. Oku kuya kushukumisela abavelisi ukuba bavelise kwaye baphuhlise izisombululo ze-LNB ezisebenzayo nezithembekileyo.
