I te mea ka tutuki nga tikanga o runga ake nei, karekau e hiahiatia he whakamatautau tuku. Heoi, kei te Kaihanga Kaihautu tonu te kawenga mo te whakamatautau i a raatau hua mutunga mo etahi atu whakaritenga tautukunga e hiahiatia ana me tenei waahanga kua whakauruhia (mo muaampte, tukunga taputapu matihiko, nga whakaritenga a-roto PC, aha atu).

Te Tapanga me nga Korero Tautukunga
Me whakarato e nga kaihanga hua manaaki he tapanga-a-tinana, e-tapanga e kii ana "Kei roto te ID FCC:
2AC7Z-ESPS2SOLO2” me o raatau hua kua oti.

Nga korero mo nga momo whakamatautau me etahi atu whakaritenga whakamatautau

  • Auautanga Mahi:
    • WiFi: 2412 ~ 2462 MHz
  • Te maha o nga hongere:
    • WIFI: 11
  • Whakawaenga:
    • WiFi: DSSS; OFDM

Ko nga kaihanga kaihautu me mahi i nga whakamatautau o te whakaputanga me te whakahaere i te tukunga me te whakaputanga tinihanga, me era atu, i runga i nga tikanga whakamatautau mo te kaiwhakawhiti modular tu-koke i roto i te kaihautu, me te maha o te tuku i nga waahanga me etahi atu tuku i roto i te hua manaaki. Mena ka tutuki nga hua whakamatautau katoa o nga momo whakamatautau ki nga whakaritenga a te FCC, katahi ka taea te hoko ma te ture.

Ētahi atu whakamātautau, Wāhanga 15 Wāhanga iti B
Ko te kaikawe whakawhiti he FCC anake te mana mo te FCC Wāhanga 15 Waahanga C 15.247 a ko te kaihanga hua kaihautu te kawenga mo te ū ki etahi atu ture FCC e pa ana ki te kaihautu kaore i hipokina e te tuku tuku tohu tohu. Mena ka hokohoko te kaaiti i a raatau hua he mea e tika ana ki te Waahanga 15 Wāhanga-iti B (i te mea kei roto ano hoki te iahiko matihiko-radiator), katahi ka tukuna he panui e kii ana ko te hua kaihautu whakamutunga kei te hiahia tonu te Waahanga 15 Waahanga B kia whakamatauhia nga hanganga ture me te kaiwhakawhiti tauira. tāuta.

Kua whakamatauria enei taputapu, kua kitea e u ana ki nga rohe mo tetahi taputapu matihiko Class B, i runga i te Wahanga 15 o nga Ture FCC. I hangaia enei rohe ki te whakarato i te whakamarumaru tika mai i nga pokanoa kino i roto i te whakaurunga whare. Ka whakaputa, ka whakamahi, ka taea e tenei taputapu te whakaputa i te hiko auau reo irirangi, a, ki te kore e whakauruhia ka whakamahia i runga i nga tohutohu, ka raru pea nga korero reo irirangi.

Heoi ano, karekau he taurangi ka kore e puta he pokanoa ki tetahi whakaurunga. Mena ka raru nga taputapu i runga i te reo irirangi, pouaka whakaata ranei, ka taea te whakatau ma te whakaweto i nga taputapu, ka akiakihia te kaiwhakamahi ki te ngana ki te whakatika i te pokanoa ma tetahi o nga tikanga e whai ake nei:

  • Whakahoahoa, nukuhia ranei te antenna whiwhi.
  • Whakanuia te wehenga i waenga i te taputapu me te kaiwhiwhi.
  • Honoa te taputapu ki tetahi putanga i runga i te ara iahiko rereke mai i tera e honoa ana te kaiwhiwhi.
  • Korero atu ki te kaihoko, ki tetahi tohunga hangarau reo irirangi/TV mo te awhina.

Ka tutuki tenei taputapu ki te Wahanga 15 o nga Ture FCC. Ko te mahi i raro i nga tikanga e rua e whai ake nei:

  • Kare pea tenei taputapu e whakararu kino.
  • Me whakaae tenei taputapu ki nga pokanoa kua tae mai, tae atu ki te pokanoa ka puta he mahi kore.

Tupato:
Ko nga huringa me nga whakarereketanga kaore i tino whakaaehia e te roopu kawenga mo te hanganga ture ka whakakorehia te mana o te kaiwhakamahi ki te whakahaere i nga taputapu.

Ko enei taputapu e whai ana ki nga rohe whakakitenga iraruke FCC RF kua whakaritea mo te taiao kore whakahaere. Ko tenei taputapu me ona antenna me kaua e noho tahi me te mahi tahi me etahi atu antenna, kaiwhakawhiti ranei. Ko nga antenna e whakamahia ana mo tenei kaiwhakawhiti me whakauru kia 20 cm te tawhiti o te wehenga mai i nga tangata katoa, kaua hoki e noho tahi me te mahi tahi me etahi atu antenna, kaiwhakawhiti ranei.

Tohutohu Whakauru OEM
Ko tenei taputapu anake mo nga kaiwhakauru OEM i raro i nga tikanga e whai ake nei:

  • Ko te kōwae whakawhiti karekau pea e noho tahi me tetahi atu kaikawe, antenna ranei.
  • Me whakamahi noa te kōwae me te/ngā antenna o waho i whakamatauria tuatahitia me te whakamana ki tenei kōwae.

I te mea ka tutuki nga tikanga o runga ake nei, karekau e hiahiatia he whakamatautau tuku. Heoi, kei te Kaihono OEM tonu te kawenga mo te whakamatautau i a raatau hua mutunga mo etahi atu whakaritenga hanganga ture e hiahiatia ana me tenei waahanga kua whakauruhia (mo muaampte, tukunga taputapu matihiko, nga whakaritenga a-roto PC, aha atu).

Te Mana o te Whakamahi i te Tiwhikete Tiwhikete
Mena kaore e taea te whakatutuki i enei tikanga (mo te exampKo etahi whirihoranga pona, he waahi tahi ranei me tetahi atu kaiwhakawhiti), katahi ka kore te whakamanatanga FCC mo tenei waahanga me nga taputapu kaihautu e kiia ana he whaimana, kaore e taea te whakamahi i te FCC ID o te waahanga ki te hua whakamutunga. I roto i enei ahuatanga, ma te Kaiwhakauru OEM te kawenga mo te arotake ano i te hua mutunga (tae atu ki te kaiwhakawhiti) me te whiwhi mana motuhake FCC.

Whakamutunga Tapanga Hua
Ko te hua mutunga whakamutunga me tapaina ki tetahi waahi ka kitea me enei e whai ake nei: "Kei roto i te Waea Whakawhiti FCC ID: 2AC7Z-ESPS2SOLO2".
