Dziwani zambiri za IEEE 802.11a mu protocol ya WiFi, yomwe ndi protocol yoyamba ya 5G band.
1) Kutanthauzira kwa Protocol:IEEE 802.11a ndi muyezo wosinthidwa wa 802.11 ndi muyezo wake woyambirira, womwe unavomerezedwa mu 1999. Protocol yayikulu ya 802.11a muyezo ndi yofanana ndi yoyambira, koma ma frequency ake ogwirira ntchito ndi 5GHz, 52 orthogonal frequency division multiplexing subcarriers ndi. zogwiritsidwa ntchito, ndipo kuchuluka kwapazipita koyambirira kotumizira deta ndi 54Mb/s, zomwe zimapangitsa kuti zikwaniritse zofunikira zapakatikati (20MB/s) pamaneti enieni. Inde, ngati kuli kofunikira, chiwerengero cha deta chikhoza kuchepetsedwa kukhala 48MB / s, 36MB / s, 24MB / s, 18MB / s, 12MB / s, 9MB / s, kapena 6MB / s. 802.11a ili ndi njira za 12 zomwe sizimalumikizana, zomwe 8 zimagwiritsidwa ntchito m'nyumba ndipo zina 4 zimagwiritsidwa ntchito pofalitsa mfundo. Sizingagwirizane ndi 802.11b pokhapokha ngati chipangizo chomwe chimatsatira miyezo yonse iwiri chikugwiritsidwa ntchito.
2) IEEE 802.11a Ubwino ndi kuipa:popeza gulu la 2.4G linkagwiritsidwa ntchito kwambiri panthawiyo, lidachulukana kwambiri. Chifukwa chake, kugwiritsa ntchito gulu la 5g ndikuwongolera kofunikira kwa 802.11a, komwe kuli ndi mikangano yochepa. Komabe, pafupipafupi chonyamulira chachikulu alinso ndi zotsatira zoipa. Mtunda wotumizira ndi wochepera 802.11b/g; mwachidziwitso, zizindikiro za 5g zimatsekedwa mosavuta ndi kutengeka ndi makoma, omwe ali oyenerera kufalikira kwa mzere wowongoka komanso wosasokonezeka, zomwe zimapangitsa kuti pakhale kufunikira kogwiritsa ntchito malo ochulukirapo. Chifukwa chake, kufalikira kwa 802.11a ndikocheperako kuposa kwa 801.11b. 802.11a idzayambitsanso mavuto chifukwa kutalika kwake kudzatengedwa ndi zipangizo zapafupi, kupangitsa kuti chizindikiro chake chikhale chofooka komanso chodziwika bwino pakapita nthawi. Komabe, popeza palibe zizindikiro zambiri zosokoneza pafupi, kutulutsa kwa 802.11a nthawi zambiri kumakhala kwabwino.
Zomwe zili pamwambazi ndizozidziwitso za protocol ya IEEE802.11a ndi ubwino wake ndi kuipa kwake.
Zomwe zili pamwambazi ndikulongosola kwa chidziwitso cha IEEE 802.11a chobweretsedwa kwa inuMalingaliro a kampani Shenzhen HDV Phoelectron Technology Co., Ltd. ndikukhulupirira kuti nkhaniyi ingakuthandizeni kukulitsa chidziwitso chanu. Kupatula nkhaniyi ngati mukuyang'ana kampani yabwino yopanga zida zoyankhulirana zama fiber zomwe mungaganizirezambiri zaife.
Zinthu zoyankhulirana zopangidwa ndi kampaniyi zikuphimba:
Module: Optical fiber modules, Ethernet modules, Optical fiber transceiver modules, optical fiber access modules, SSFP Optical modules,ndiSFP kuwala ulusi, ndi zina.
ONUgulu: EPON ONU, AC ONU, Optical fiber ONU, CATV ONU, GPON ONU, XPON PA, ndi zina.
OLTkalasi: Kusintha kwa mtengo wa OLT, Mtengo wa GPON OLT, EPON OLT, kulankhulanaOLT, ndi zina.
Zomwe zili pamwambazi zimatha kuthandizira zochitika zosiyanasiyana zapaintaneti. Pazinthu zomwe tatchulazi, gulu la akatswiri komanso lamphamvu la R & D limaphatikizidwa kuti lipereke chithandizo chaukadaulo kwa makasitomala, ndipo gulu loganiza bwino komanso laukadaulo litha kupereka chithandizo chapamwamba kwambiri kwamakasitomala koyambirira.kukambilanandipo kenako ntchito.
