I-5G base station test next weather satellite ukuxhumana ngaphandle kwesimo

Muva nje, i-Luzhou City Economic and Information Bureau ibambe uchungechunge ngokusetshenziswa kokuphazamiseka kokuxhumanisa iziteshi eziyisisekelo ze-5G, futhi yaxhumanisa ukuthunyelwa kweziteshi eziyisisekelo ze-5G namayunithi okuxhumana ngesathelayithi akhona. Kusukela ngoMeyi 11 kulo nyaka, i-Shengzhou Meteorological Bureau ithole ukuthi imishini yokuxhumana ngesathelayithi inokwehluleka ukwamukela isignali. Ngemva kokuhlolwa okuphindaphindiwe nophenyo, kutholakala ukuthi umthelela weziteshi eziningi zokuhlola ezisanda kufakwa ze-5G eduze ne-Meteorological Bureau. U-Li Xiaoyong, umqondisi we-Information Centre ye-Ganzhou Meteorological Bureau, utshele izintatheli ukuthi lezi ziteshi ze-5G ziqhele ngamamitha angamakhulu amabili noma amathathu kuphela ukusuka esiteshini sokwamukela i-satellite ye-meteorological. U-Li Xiaoyong wethule ukuthi imishini yokuxhumana ngesathelayithi yesiteshi sesisekelo se-5G kanye nomnyango wesimo sezulu zisebenzisa amabhendi efrikhwensi ye-electromagnetic wave asondele, ngakho ukudluliswa kwesimo sezulu kwabonakala kuyisiphazamiso. Kuze kube manje, i-Cangzhou Meteorological Bureau kamuva yenza izinguquko, yafaka inethiwekhi yokuvikela amasignali, futhi yashintshela kumugqa we-broadband ukuze yamukele idatha yesimo sezulu.

    Ukuphazamiseka kwezokuxhumana ngesathelayithi yesimo sezulu kwenzeka, isisekelo esisha se-5G eduze nokuthola.

    Kusukela ngoMeyi 11 kulo nyaka, abasebenzi baseGanzhou Meteorological Bureau bathole ukuthi idatha yokudluliselwa kwe-downlink yohlelo lokuxhumana ngesathelayithi ayikwazanga ukutholwa ngokuphelele. "Ngaleso sikhathi, izinga lokuxhumana lancishiswa ngokushesha. Sithola idatha, sathi isignali yesathelayithi ibizwe kukhiye, futhi asikwazanga ukungena eketangeni." U-Li Xiaoyong uthe le mishini isisetshenziswe iminyaka engaphezu kwe-10, futhi akukaze kube khona ukwehluleka okunjalo phambilini. . Abasebenzi be-Meteorological Bureau benze izivivinyo eziningi kanye nophenyo, kodwa izizathu azitholakalanga. Maphakathi noJuni, i-Cangzhou Meteorological Bureau yabonisana nehhovisi lomsakazo le-Cangzhou Economic and Information Bureau ngalesi simo, kanti i-Cangzhou Economic and Trade Bureau yahlela ukuthi isiteshi esiqapha umsakazo siye endaweni ukuze sicutshungulwe futhi sixazulule izinkinga, saqeda imishini ngokwayo. futhi ekugcineni sinqume ukuxhumana ngocingo eduze. Ukuphazamiseka kwesignali okudluliselwa yisiteshi sesisekelo se-5G kubangelwa. U-Li Xiaoyong uthe lezi ziteshi eziyisisekelo ze-5G zifakwe emnyangweni wezokuxhumana ukuze zihlolwe. Abazange bathole izindaba ngaphambili. "Ngaleso sikhathi, ngisanda kuzwa ukuthi amadolobha amakhulu asevele enza ukuhlolwa kwe-5G. Angazi ukuthi iGanzhou nayo iyakwenza lokhu."

    Kamuva, ukuxhumanisa nokuxhumana kwembula ukuthi umnyango wezokuxhumana ufake iziteshi ezintathu noma ezine ze-5G eduze ne-Meteorological Bureau, futhi isiteshi sokwamukela isathelayithi sokuxhumana kwesiteshi sesimo sezulu esiseduze sasingamamitha angamakhulu amabili noma amathathu kuphela. Ngemva kokuxhumana nomnyango wezokuxhumana, ngemva kokuba iziteshi zokuhlola zivaliwe, ukwehluleka kwesistimu yezokuxhumana esiteshini sezulu kwanyamalala. Qala enye indlela,

    Awukho umthelela ezibikezelweni zesimo sezulu Esikhathini esingaphezu kwenyanga eyodwa ukuxhumana ngesathelayithi kwaqhubeka nokuthinteka, i-Ganzhou Meteorological Bureau inikeze amandla ukudluliswa kwezintambo ezizimele ze-broadband. U-Li Xiaoyong uthe nakuba ukuxhumana ngesathelayithi kuphazamisekile, izinga lesibikezelo sezulu eZhangzhou alizange lithinteke.

    U-Li Xiaoyong wethule ukuthi umthelela wesiteshi se-5G ku-Ganzhou Meteorological Bureau umthelela wokuxhumana. I-Ganzhou Meteorological Bureau isebenzisa isistimu yokuxhumana engenantambo, esetshenziswa kakhulu ukuqoqa nokusabalalisa idatha yesimo sezulu. Ngenxa yokuthi ukuxhumana ngesathelayithi kunenani elikhulu lokudlulisela kanye nokudluliswa kwedatha okusheshayo, kuvamile ukusebenzisa ukuxhumana komsakazo.

    Ngemuva kokuthi ukuxhumana nomsakazo kuthinteke ukuphazamiseka, i-Zhangzhou Meteorological Bureau yenza uhlelo oluphuthumayo lusebenze futhi yashintshela kusignali yokudlulisa i-broadband. U-Li Xiaoyong utshele intatheli ukuthi i-Shengzhou Meteorological Bureau ithenge ulayini we-broadband wenkampani yenethiwekhi, futhi ukwamukela nokusabalalisa imininingwane yayo igcinwe ivulekile ngemuva kokuphazanyiswa kokuxhumana okungenantambo.

    U-Li Xiaoyong uthe ziningi izindlela zokuyixazulula. Eqinisweni, ungathola futhi isikhungo esiseduze sedolobha kanye nesifunda sezezulu ukuze sikusize ukucubungula idatha okwesikhashana. Ngemva kokunquma ukuphazamiseka kwesignali, i-Zhangzhou Meteorological Bureau iphinde yafaka inethiwekhi yokuvikela esiteshini sayo sokwamukela isathelayithi. Ukuhlolwa kuthole ukuthi inethiwekhi evikelayo ingaxazulula inkinga yokuphazamiseka kwesignali ye-5G.

    Mayelana nomthelela wezimpawu ze-5G kwezokuxhumana ngesathelayithi ezikhona endaweni, iKhomishana Yezomnotho Nezohwebo yaseCangzhou ayizange iphendule okwengeziwe.

    Kungani uphazamisa ukuxhumana kwe-meteorological satellite? Ngoba ibhendi yegagasi kagesi iseduze kakhulu

    U-Li Xiaoyong utshele izintatheli ukuthi isizathu esenza ukuthi kuphazanyiswe ukuxhumana ngesathelayithi kwe-Zhangzhou Meteorological Bureau kubangelwe amaza amagagasi kagesi asondele kakhulu kulaba bobabili. U-Li Xiaoyong uthe ngaphezu komthelela womnyango wesimo sezulu, amanye amayunithi asebenzisa i-C-band yezokuxhumana ngesathelayithi angase abhekane nezinkinga ezinjalo. Ngokusho kwakhe, ukuhlolwa kwesiteshi se-5G se-Sichuan kwaqala ukuhlolwa emadolobheni amaningana, futhi isigameko saso sokuphazamiseka kwesignali senzeke. Kodwa-ke, uLi Xiaoyong uthe le nkinga akunzima ukuyixazulula, futhi umthelela unomkhawulo futhi uyalawuleka. Isibonelo, ukufaka inethiwekhi evikelekile kufakazelwe ukuthi kusebenza ngempumelelo.

    UMa Yan, uprofesa we-Network Technology Research Institute yaseBeijing University of Posts and Telecommunications kanye nomqondisi we-Information Network Center, utshele izintatheli ukuthi "isiteshi esivamile sokuxhumana sendabuko sisuka kumakhilomitha ambalwa kuya kwamakhilomitha ayishumi, futhi kungcono ukugwema. lolu hlobo." UMa Yan uthe endaweni encane yedolobha, Ukusebenzisana phakathi kwesiteshi sesisekelo se-5G kanye nesiteshi sesisekelo sokuxhumana sendabuko kudinga izindlela zobuchwepheshe zokuxazulula.

    Uchwepheshe: Isignali ye-5G ngeke ithinte ukuqapha isimo sezulu

    U-Li Xiaoyong utshele izintatheli ukuthi ukuxhumana ngesathelayithi kweZhangzhou Meteorological Bureau kuthinteke esiteshini sesisekelo se-5G, futhi kwakungewona umqondo ofanayo nesiginali ye-5G ethinteke inethiwekhi yangaphambilini.

    Imithombo yezindaba yangaphambilini ibika ukuthi ngenxa yokuthi imvamisa yesignali ye-5G ifana nobude beza bemvelo bomhwamuko wamanzi, izothinta ukubhekwa kwesimo sezulu. Ngokwemibiko, isizathu esenza amasignali e-5G asongela ukunemba kwesibikezelo sezulu ukuthi ibhendi yefrikhwensi ezosetshenziswa yi-United States ukuthuthukisa amanethiwekhi okuxhumana e-5G ithatha ibhande cishe elingu-23.8 GHz (gigahertz), kanye nesiginali nomhwamuko wamanzi leli bhendi Amaza amaza emvelo anikeza amaza amasignali afanayo kakhulu. UMa Yan, uprofesa e-Network Technology Research Institute yaseBeijing University of Posts and Telecommunications, uthe, "Isimo sangempela asisibi kakhulu njengaleso esibikwe abezindaba bakwamanye amazwe, ngoba amaza e-5G asetshenziswa ezweni ngalinye ahlukile." Ngokombiko we-Communication Information Report, amasathelayithi amanje ase-China e-Fengyun meteorological asetshenziswa. Amabhendi amafrikhwensi angu-137 GHz no-1700 GHz. Uma kuqhathaniswa ne-2.6 GHz kuya ku-4.9 GHz yamasiginali we-5G, igebe lisobala, futhi akukho ukuphazamiseka phakathi kwazo.
