    Okwu mmalite dị nkenke maka eriri Wi-Fi

    Oge nzipu: Jun-14-2022

    Antenna bụ a passive ngwaọrụ, tumadi na-emetụta OTA ike na uche, mkpuchi na anya, na OTA bụ ụzọ dị mkpa iji nyochaa na dozie throughput nsogbu, na-emekarị anyị tumadi maka ndị na-esonụ parameters (na-esonụ paramita adịghị atụle laabu njehie. arụmọrụ imewe antenna n'ezie ga-emetụtakwa arụmọrụ ntinye):

    a) VSWR

    Tule ogo nlegharị anya nke mgbama ntinye na ebe nri antenna. Uru a apụtaghị na arụmọrụ antenna dị mma, mana uru ahụ adịghị mma, ọ pụtara na ntinye ike na ebe nri antenna na-egosipụta karịa, ma e jiri ya tụnyere antenna ebili mmiri dị mma, ike nke nwere ike iji mee ihe maka radieshon. e belatara karịa.

    b) arụpụta ihe

    Oke ike nke antenna na-agbasa na ntinye ike na ebe nri nke antenna ga-emetụta arụmọrụ Wi-Fi OTA ozugbo (TRP) na uche (TIS).

    c) nweta

    Ọ na-anọchi anya oke ike nke ọnọdụ dị na ntụzịaka oghere gaa na antenna isi mmalite dị mma ebe a, ebe data na-agafe agafe nke OTA na-abụkarị uru kachasị nke otu ugboro (ọwa) na okirikiri, ọkachasị metụtara ebe nnyefe.

    d) TRP/TIS

    A na-enweta ihe ngosi abụọ a zuru oke site na ijikọ oghere radieshon dum (nke enwere ike ịghọta dị ka gburugburu ụlọ nyocha OTA), nke nwere ike igosipụta arụmọrụ Wi-Fi nke ngwaahịa ahụ (ngwaike PCBA + OTA nke ebu + antenna).

    Mgbe ule TRP / TIS dị iche na nke a tụrụ anya ya, kpachara anya ma Wi-Fi abanyela n'ọnọdụ ike dị ala yana ngwaahịa batrị; TRP kwesịrị ilekwasị anya na ọnọdụ ACK na ndị na-abụghị ACK, na TIS abụwo isi ihe na OTA mgbe niile, mgbe niile, nnyefe nwere ike igosipụta ụfọdụ nnyonye anya, ihe ngwanrọ ga-emetụtakwa TIS.

    Enwere ike iji TRP / TIS dị ka ụzọ dị mkpa maka nyocha nke ntinye Wi-Fi.

    e) eserese ntụzịaka

    A na-eji ya qualitatively na-enyocha mkpuchi radieshon nke ngwaahịa na mbara igwe, a na-amakarịkwa data nnwale dị ka ugboro (ọwa), ugboro ọ bụla nwere ihu atọ: H, E1 na E2, iji mara mkpuchi mkpuchi nke mgbaàmà. dum gburugburu nke antenna. Mgbe a na-eji ngwaahịa Wi-Fi n'ezie n'ebe dị anya (mgbe enweghị ike ịkọwa eserese nghazi ahụ n'ebe dị anya), a na-enyocha mkpuchi ikuku ikuku nke ngwaahịa ahụ site na ịnwale mmepụta ya site n'ọtụtụ akụkụ.

    f) mkpuchi

    Ngosipụta ikewapụ na-atụle ogo kewapụ nke eriri ọwa ọtụtụ Wi-Fi yana njikọta n'etiti antennas. Ngosipụta nkewa dị mma nwere ike ibelata njikọta n'etiti antennas ma nwee ezigbo maapụ ntụzịaka, ka igwe dum nwee mkpuchi mkpuchi ikuku dị mma.
