5G whakamātautau teihana taatai ​​kei te heke mai o te whakawhitiwhiti a-rangi i waho o te ahuatanga

TE WAI: 2019-07-31 HITS: 13

I tata nei, i whakahaerehia e te Tari Hauora o te Taiao o te Taiao o Luzhou nga korero mo te whakamahi i te paerewa wawaotanga mo nga teihana turanga 5G, me te whakarite i te tuku i nga teihana turanga 5G me nga waeine whakawhitiwhiti a-hiko. Mai i te Mei 11 i tenei tau, kua kitea e te Tari Meteorological Tuarua o Shengzhou ko nga taputapu whakawhitiwhiti a satati he tohu whakawhiwhi tohu kore. I muri i nga whakamatautau tuuturu me nga tirotirohanga, kua kitea ko te kaha o nga teihana turanga whakamatautau 5G hou i whakauruhia e tata ana ki te Meteorological Bureau. I kii a Li Xiaoyong, te Tumuaki mo te Panui Metaoretanga o te Tari Metaorological a Ganzhou e kii ana ko enei teihana turanga 5G e rua ranei e toru rau mita te tawhiti mai i te teihana meteorological reo irirangi tauwhiro whakawhiwhinga. I whakaatu a Li Xiaoyong, ko nga taputapu whakawhitiwhiti amiorangi o te teihana turanga 5G me te tari meteorological i whakamahia e nga roopu ngaru hiko hiko o te ngaru hiko, na reira ka puta te whakawhitinga meteorological. Te mutunga, ko te Cangzhou Meteorological Bureau i muri mai ka whakatikatika, ka whakauruhia he whatunga paruru tohu, ka huri ki tetahi raina whanui kia whiwhi raraunga meteorological.

    Ko te wawaotanga whakawhitiwhiti korero a te kowhiriiao ka puta, ko te turanga 5G hou e tata atu ana.

    Since May 11 this year, the staff of the Ganzhou Meteorological Bureau found that the downlink transmission data of the satellite communication system could not be completely received. "At that time, the quality of communication was immediately reduced. Receiving data, we said that the satellite signal was called into the lock, and we could not enter the chain." Li Xiaoyong said that this equipment has been used for more than 10 years, and there has been no such failure before. . The staff of the Meteorological Bureau conducted many tests and investigations, but the reasons were not found. In mid-June, the Cangzhou Meteorological Bureau consulted the radio office of the Cangzhou Economic and Information Bureau on this phenomenon, and the Cangzhou Economic and Trade Bureau arranged the radio monitoring station to go to the site for processing and troubleshooting, eliminating the equipment itself and finally determining the telecommunications nearby. The signal interference transmitted by the 5G base station is caused. Li Xiaoyong said that these 5G base stations were installed in the telecommunications department for testing. They did not get the news before. "At the time, I just heard that the big cities are already doing 5G testing. I don't know that Ganzhou is also doing this."

    Later, the coordination and communication revealed that the telecommunications department installed three or four 5G base stations in the vicinity of the Meteorological Bureau, and the nearest meteorological station communication satellite receiving station was only two or three hundred meters. After coordinating with the telecommunications department, after the test base stations were turned off, the weather station's communication system failure disappeared. Start an alternative,

    Kaore he paanga i runga i nga matapae o te kupu meteorological I roto i te neke atu i te kotahi marama ka haere tonu nga whakawhitiwhiti korero a-rangi, na te Ganzhou Meteorological Bureau i tuku te tuku i nga raina whaanui. I kii a Li Xiaoyong, ahakoa i pakaru nga whakawhitinga o te rangi, kaore i pa te kounga o te huarere huarere ki Zhangzhou.

    I whakapuaki a Li Xiaoyong ko te paanga o te teihana turanga 5G i te Tari Meteorological a Ganzhou ko te paanga ki te whakawhitiwhiti korero. Ka whakamahia e te Tari Meteorological a Ganzhou tetahi punaha whakawhitiwhiti ahokore, ka whakamahia e ia mo te kohi me te tohatoha i nga raraunga meteorological. Na te mea he nui te whakawhitinga o te whakawhitiwhiti aipurangi me te whakawhiti tere tere, kua kaha te whakamahi o te reo irirangi.

    Whai muri i te paahorotanga o te reo irirangi na te haukotia nei, na Zhangzhou Meteorological Bureau i whakahoahoa te mahere whawhati tata, ka huri ki te tohu whakawhiti whanui. I kii a Li Xiaoyong ki te kaipanui korero kua hokona e te Shengzhou Meteorological Bureau te raina whanui o te kaiwhakarato whakawhitiwhiti korero, me nga raraunga whiwhi me te tohatoha kua whakatuwherahia i muri i te pokanoa o nga whakawhitiwhiti korero ahokore.

    I kii a Li Xiaoyong, he maha nga huarahi hei whakaoti. Ina hoki, ka taea ano hoki e koe te kite i te taone nui me te kawanatanga meteorological kawanatanga hei awhina ia koe ki te tukatuka i te wa poto. Whai muri i te whakatau i te wawaotanga tohu, kua whakauruhia e te Zhangzhou Meteorological Bureau tetahi punaha paruru mo tona teihana whiwhi satati. I kitea te whakamatautau ka taea e te whatunga paruru te whakaoti i te raru whakahiatotanga tohu 5G.

    Mo te paanga o nga tohu 5G mo nga whakawhitiwhiti korero a-koiora kei te takiwa o te rohe, kaore ano kia utua e te Komihana aango me te Pakihi o Cangzhou.

    He aha te pokanoa ki nga whakawhitiwhitinga amiorangi meteorological? Na te mea he tino tata te peka ngaru hiko

    Li Xiaoyong told reporters that the reason why the satellite communication of the Zhangzhou Meteorological Bureau was disturbed was caused by the relatively close electromagnetic wave bands of the two. Li Xiaoyong said that in addition to the impact of the meteorological department, other units using C-band satellite communications may also face such problems. According to him, Sichuan's 5G base station test began testing in several cities, and its signal interference phenomenon has also occurred. However, Li Xiaoyong said that this problem is not difficult to solve, and the impact is limited and controllable. For example, installing a shielded network has been proven effective.

    Ma Yan, professor of the Network Technology Research Institute of Beijing University of Posts and Telecommunications and director of the Information Network Center, told reporters that "the general traditional communication base station ranges from a few kilometers to ten kilometers, and it is better to avoid this range." Ma Yan said that within a small area of the city, The interaction between the 5G base station and the traditional communication base station requires technical means to solve.

    Tohunga: Ko te tohu 5G kaore e pa ki te aro turuki i te rangi

    I kii a Li Xiaoyong ki nga kaipoipo ko te whakawhitiwhiti a satui o Zhangzhou Meteorological Bureau i pa ki te teihana turanga 5G, kaore hoki i te rite te whakaaro o te tohu 5G e pa ana ki te whatunga o mua.

    Kua panuitia e nga kaaparata o mua ko te mea te rite te 5G tohu ki te rite o te roangaru o te kaapu o te wai, ka pa ki te aro turuki i te rangi. E ai ki nga ripoata, ko te take he aha te tohu 5G ka whakawehi i te tika o te matapae huarere, ko te roopu rererangi ka whakamahia e te United States ki te whakawhanake i nga hononga whakawhiti 5G e noho ana ki te roopu o te 23.8 GHz (gigahertz), me te tohu me te ruaki wai o te tenei band Ko nga huringa taiao e tuku ana i nga huringa tohu rite tonu. Ko Ma Yan, he kaiako i te Rorohiko Whakawhanui Hangarau Hangarau o te Whare Wananga o Te Whare Wānanga o Beijing, i kii, "Ko te ahuatanga tuuturu kaore i te nui te korero mai i nga purongo a te iwi ke, no te mea he rereke nga momo 5G i whakamahia i ia whenua." E ai ki te Ripoata Korero Whakawhiti, e whakamahia ana nga huringa meteorological a Fengyun o Haina inaianei. Ko nga roopu whaanui ko te 137 GHz me te 1700 GHz. Ka whakatauritea ki te 2.6 GHz ki te 4.9 GHz o nga tohu 5G, ka kitea ake te kaanga, kaore hoki e pokanoa tetahi atu.
