Mara waya ta amfani da lambar sikandi a cikin kasuwa

Wannan karon akwai kwastomomi da yawa da ke ba da shawarar na'urar daukar hoto mara waya wacce iri? Menene na'urar daukar hoto mara waya ta dogara dashi don sadarwa? Menene banbanci tsakanin na'urar daukar hoto ta Bluetooth da sikanin mara waya?

 

Karamin sikanin iska mara waya wanda kuma aka sani da sikanin sikandi mara waya, ya banbanta da mai karanta siginar lambar sikandire. Gabaɗaya ta hanyar Bluetooth, WiFi da sauran watsa bayanai, ba za a iyakance su ta tsawon bayanan watsa bayanan kebul ba, mai sauƙin amfani.

 

Misali, kamar linzamin kwamfuta da kuma beran mara waya, amfanin beran mara waya ba a hana shi da kebul din bayanai ba, kuma ya fi sauki a yi amfani da shi. Hakanan, na'urar daukar hotan iska, kamar linzamin mara waya, yana da mai karɓar waya. Ana kiran shi donggle, ko mai karɓar Bluetooth. (Wannan ba lallai bane gaskiya, kodayake, saboda yana 433MHz ko 2.4GHz, wanda yafi kowa.)

 

Da farko dai, ana iya rarrabe tsarin sikanin iska mara waya daga nau'ikan fasahar sadarwa mara waya da aka yi amfani da su.

 

Hanyoyin sadarwar mara waya ta yau da kullun da ake amfani da su ta hanyar amfani da na'urar sikanin waya sun hada da Bluetooth, 433MHz, 2.4GHz

 

A halin yanzu, 433MHz shine mafi yawan yanayin yanayin sadarwa mara waya. Amfanin wannan zangon mitar shi ne cewa nisan sadarwar mara waya ya fi 2.4GHz, saboda mitar ta yi kasa da 2.4GHz kuma nisan ya fi tsayi, wanda ya fi dacewa don kauce wa matsaloli kuma nesa da yaduwar nesa. Yawancin lokaci, 433MHz a sararin samaniya, zai iya kaiwa mita 100 -400 na nesa na watsawa, kuma a cikin ɗakin, nisan sadarwarsa zai iya kaiwa mita 20 ~ 60 mita, mita 20 ~ mita 30 na aiki ya isa sosai. 2.4GHz na'urar daukar hoto mara waya, aikin bangon shiga ba kyau, gaba daya bango daya, kuma nesa bazaiyi nisa ba, karfin tsangwama mai karfi, 2.4GHz sama da saurin watsa 433MHz, wanda yafi dacewa da yanayin wayar hannu.

 

Don haka, yawancin amfani da mitar mara waya ita ce 2.4GHz. Wannan mitar ita ce hanyar NFC da aka fi amfani da ita, kuma Bluetooth hakika mitar 2.4GHz ce, amma Bluetooth lamari ne na musamman na 2.4GHz. Na'urar daukar hoto mara waya ta 2.4GHz yawanci tana magana ne a tsakanin mita 10, iri ɗaya da Bluetooth.

 

Sadarwar mara waya ta Bluetooth haƙiƙa yanayin yanayin sadarwa mara waya ta 2.4GHz. Gabaɗaya, kwamfyutocin tafi-da-gidanka da wayoyin hannu suna sanye take da masu karɓar Bluetooth. Wato, Bluetooth ba ta buƙatar ƙarin mai karɓar mara waya, kuma 433MHz da 2.4GHz suna da mai karɓar mara waya (kowane mizanin sadarwa mara waya ya ɗan bambanta, ba lallai ba ne ya zama gama gari, Bluetooth duk kayan aikin ladabi ne na sadarwa).

 

A ƙarshe, magana game da na'urar daukar hotan takardu na WiFi, a zahiri, ba su da yawa a cikin kasuwa, gabaɗaya ƙirar amfani da shirin.
