SRRC imakwaniritsa zofunikira za miyezo yatsopano ndi yakale ya 2.4G, 5.1G, ndi 5.8G

Akuti Unduna wa Zamakampani ndi Ukadaulo Wachidziwitso udapereka Chikalata Na. 129 pa Okutobala 14, 2021, chamutu wakuti "Chidziwitso pa Kulimbitsa ndi Kukhazikika Kwawailesi yakanema mu 2400MHz, 5100MHz, ndi 5800MHz Frequency Bands", ndipo Document No. 129 idzagwira ntchito chivomerezo chachitsanzo molingana ndi zofunikira zatsopano pambuyo pa Okutobala 15, 2023.

Chikumbutso chokoma mtima: Nthawi yovomerezeka ya chiphaso chakale ndi mpaka Disembala 31, 2025. Ngati kampaniyo ikufunabe kupitiliza kugulitsa zinthu zakale zomwe satifiketi ikatha, iyenera kukweza ziphaso za certification osachepera miyezi isanu ndi umodzi pasadakhale ndikufunsira satifiketi. kuwonjezera masiku 30 pasadakhale.

2.Kodi ndi zinthu ziti zomwe SRRC imatsimikiziridwa ndi?

3.2 DFS yosiyana pang'ono
Zida zotumizira opanda zingwe zikuyenera kutengera ukadaulo wa Dynamic Frequency Selection (DFS) wosokoneza, womwe uyenera kusinthidwa kukhala ndipo sungathe kukhazikitsidwa ndi mwayi wothimitsa DFS.
Kuwonjezera kwa zipangizo zotumizira mauthenga opanda zingwe ziyenera kutengera luso la Transmission Power Control (TPC) loletsa kusokoneza, ndi TPC yosachepera 6dB; Ngati palibe ntchito ya TPC, mphamvu ya radiation ya omnidirectional yofanana ndi mphamvu ya radiation ya omnidirectional mphamvu yowoneka bwino iyenera kuchepetsedwa ndi 3dB.
3.3 Kuchulukitsa kuyesa kupewa kusokoneza
Njira yotsimikizira kupewa kusokoneza kwenikweni imagwirizana ndi zofunikira zosinthika za satifiketi ya CE.
3.3.1 2.4G zofunika kupewa kusokoneza:
①Zikapezeka kuti ma frequency akhalapo, kufalitsa sikuyenera kupitilira pafupipafupi panjirayo, ndipo nthawi yokhalamo sayenera kupitilira 13ms. Izi zikutanthauza kuti, kufalitsa kuyenera kuyimitsidwa mkati mwa nthawi yomwe njanji imakhala.
② Chipangizochi chimatha kusungitsa kufalitsa kwachidziwitso chachifupi, koma ntchito yozungulira siginecha iyenera kukhala yochepera kapena yofanana ndi 10%.
3.3.2 Zofunikira popewa kusokoneza 5G:
①Zikapezeka kuti pali siginecha yokhala ndi ma frequency ogwiritsira ntchito kuposa momwe imawonekera, kutumizira kuyenera kuyimitsidwa nthawi yomweyo, ndipo nthawi yayitali yokhala ndi njira ndi 20ms.
② Mkati mwa nthawi yowonera 50ms, kuchuluka kwa ma siginecha owongolera afupiafupi kuyenera kukhala ochepera kapena ofanana ndi nthawi za 50, ndipo munthawi yomwe tawonera pamwambapa, nthawi yonse yotumizira ma siginecha yayifupi iyenera kukhala yosakwana 2500us kapena Kuzungulira kwa ntchito kwa chizindikiro chapamtunda chachifupi sayenera kupitirira 10%.
3.3.3 5.8G Zofunika Kupewa Kusokoneza:
Onse ndi malamulo akale ndi CE, palibe chofunikira kuti 5.8G kusokoneza kusokoneza, kotero kupewa kusokoneza 5.8G kumabweretsa chiopsezo chachikulu poyerekeza ndi 5.1G ndi 2.4G wifi.
3.3.4 Bluetooth (BT) zofunika kupewa kusokoneza:
SRRC yatsopano imafuna kuyesa kulepheretsa kusokoneza kwa Bluetooth, ndipo palibe zoletsa (Chitsimikizo cha CE chimangofunika mphamvu zazikulu kuposa 10dBm).
Zomwe zili pamwambazi ndizo zonse zomwe zili m'malamulo atsopano. Tikukhulupirira kuti aliyense atha kulabadira nthawi yotsimikizika yazinthu zawo komanso kusiyana kwa kuyesa kwazinthu zatsopano munthawi yake. Ngati muli ndi mafunso ena okhudza malamulo atsopanowa, chonde khalani omasuka kufunsa nthawi iliyonse!
