3.2 DFS yakasiyana zvishoma
Michina yekutapurirana isina waya inofanirwa kutora tekinoroji yeDynamic Frequency Selection (DFS) yekukanganisa, iyo inofanirwa kuchinjirwa uye isingagone kusetwa nesarudzo yekudzima DFS.
Kuwedzerwa kwemichina yekufambisa isina waya kunofanirwa kutora tekinoroji yeTransmission Power Control (TPC) yekukanganisa, ine TPC yemhando isingasviki 6dB; Kana pasina TPC basa, iyo yakaenzana omnidirectional mwaranzi simba uye yakaenzana omnidirectional nemwaranzi simba spectral density muganho inofanira kudzikiswa ne3dB.
3.3 Wedzera kupindira kudzivirira kuyedzwa
Iyo yekukanganisa yekudzivirira nzira yekumisikidza inonyanya kuenderana nezvinodavirwa zveEC certification.
3.3.1 2.4G kupindira kudzivirira zvinodiwa:
① Kana zvaonekwa kuti frequency yakagarwa, kutapurirana hakufanire kuenderera pane iyo chiteshi frequency, uye nguva yekugara haifanire kudarika 13ms. Kureva kuti, kutapurirana kunofanirwa kumiswa mukati menguva yakatorwa chiteshi.
② Chishandiso chinogona kuchengetedza pfupi kudzora chiratidzo chekufambisa, asi kutenderera kwechiratidzo kunofanirwa kunge kuri kushoma kana kuenzana ne10%.
3.3.2 5G kupindira kudzivirira zvinodiwa:
①Kana zvaonekwa kuti pane chiratidzo chine frequency yekushandisa yakakwira kupfuura yekuona chikumbaridzo, kutapurirana kunofanirwa kumiswa nekukasira, uye iyo yakanyanya chiteshi nguva yekugara i20ms.
② Mukati me50ms yekutarisa nguva, nhamba yepfupi yekudzora kusaina chiratidzo chekufambisa kunofanirwa kunge kuri kushoma kana kuenzana ne50 nguva, uye mukati menguva yekutarisa iri pamusoro, nguva yakazara yekupfupisa chiratidzo chekudzora chiratidzo chemidziyo inofanira kunge isingasviki 2500us kana basa kutenderera kwenzvimbo pfupi yekusaina chiratidzo chekufambisa hachifanirwe kudarika 10%.
3.3.3 5.8G Kupindira Kudzivirira Zvinodiwa:
Zvose nemirairo yekare uye CE, hapana chinodiwa chekudzivirira kupindira kwe 5.8G, saka kudzivirira kupindira kwe5.8G kunoisa njodzi huru kana ichienzaniswa ne5.1G uye 2.4G wifi.
3.3.4 Bluetooth (BT) kupindira kudzivirira zvinodiwa:
Iyo SRRC itsva inoda kuyedza kudzivirira kupindira kweBluetooth, uye hapana mamiriro ekuregererwa (CE certification inongodiwa kune simba rakakura kupfuura 10dBm).
Izvo zviri pamusoro ndizvo zvese zviri mukati memitemo mitsva. Isu tinovimba kuti munhu wese anogona kutarisisa kunguva yekusimbisa chitupa chezvigadzirwa zvavo uye mutsauko mukuyedzwa kwechigadzirwa chitsva nenguva. Kana uine mimwe mibvunzo pamusoro pemitemo mitsva, ndapota inzwa wakasununguka kubvunza chero nguva!
