    Chidule Chachidule cha Ma Antennas a Wi-Fi

    Nthawi yotumiza: Jun-14-2022

    Mlongoti ndi chipangizo kungokhala chete, makamaka zimakhudza mphamvu OTA ndi tilinazo, Kuphunzira ndi mtunda, ndipo OTA ndi njira yofunika kusanthula ndi kuthetsa vuto throughput, kawirikawiri ife makamaka kwa magawo otsatirawa (zigawo zotsatirazi saganizira zolakwika zasayansi; mawonekedwe enieni a antenna adzakhudzanso magwiridwe antchito):

    a) VSWR

    Yezerani kuwonetsetsa kwa ma siginecha olowetsa pamalo operekera mlongoti. Mtengowu sukutanthauza kuti mlongoti wa mlongoti ndi wabwino, koma mtengo wake si wabwino, zikutanthauza kuti kulowetsa mphamvu kumalo odyetserako mlongoti kumawonekera kwambiri, poyerekeza ndi mlongoti wabwino woyima bwino, mphamvu yomwe ingagwiritsidwe ntchito popanga ma radiation. yachepetsedwa kwambiri.

    b) kuchita bwino

    Chiyerekezo cha mphamvu yowulutsidwa ndi mlongoti kupita ku malo odyetsera a mlongoti zidzakhudza mwachindunji mphamvu ya Wi-Fi OTA (TRP) ndi sensitivity (TIS).

    c) phindu

    Imayimira chiŵerengero cha mphamvu ya malo opita ku malo abwino a gwero la antenna apa, pamene deta yokhazikika ya OTA nthawi zambiri imakhala yopindulitsa kwambiri pafupipafupi (channel) mu gawo, makamaka zokhudzana ndi mtunda wotumizira.

    d) TRP/TIS

    Zizindikiro ziwiri zatsatanetsatanezi zimapezedwa pophatikiza gawo lonse la radiation pamalo aulere (omwe amatha kumveka ngati malo a labotale a OTA), omwe amatha kuwonetsa mwachidwi kachitidwe ka Wi-Fi (PCBA hardware + OTA performance of mold + antenna).

    Pamene kuyesa kwa TRP / TIS kuli kosiyana ndi kuyembekezera, tcherani khutu ngati Wi-Fi imalowa mumagetsi otsika ndi zinthu zamagetsi zamagetsi; TRP iyenera kuyang'ana pa ACK ndi mawonekedwe osakhala a ACK, ndipo TIS nthawi zonse yakhala mfundo yofunika kwambiri mu OTA, pambuyo pake, kufalitsa kungangowonetsa kusokoneza kwina, mapulogalamu a mapulogalamu adzakhudzanso TIS.

    TRP / TIS itha kugwiritsidwa ntchito ngati njira yofunikira pakuwunika matulutsidwe a Wi-Fi.

    e) chithunzi cholowera

    Amagwiritsidwa ntchito poyesa kuwunika momwe ma radiation amalowa mumlengalenga, ndipo zoyeserera nthawi zambiri zimasiyanitsidwa ndi ma frequency (channel), ma frequency aliwonse amakhala ndi nkhope zitatu: H, E1 ndi E2, kuti awonetse chizindikiro cha gawo lonse la mlongoti. Pamene mankhwala a Wi-Fi amagwiritsidwa ntchito patali (pamene tchati choyang'ana sichingadziwike patali), chizindikiro chopanda zingwe cha chinthucho chimatsimikiziridwa ndi kuyesa kutuluka kuchokera ku ngodya zingapo.

    f) kutsekereza

    Digiri yodzipatula imayesa kudzipatula kwa tinyanga tambirimbiri ta Wi-Fi komanso kulumikizana pakati pa tinyanga. Digiri yabwino yodzipatula imatha kuchepetsa kulumikizana pakati pa tinyanga ndikukhala ndi mapu owongolera bwino, kuti makina onse azikhala ndi mawonekedwe abwino opanda zingwe.
