    Gulu la Ma Wireless Networks [Kufotokozera]

    Nthawi yotumiza: Sep-02-2022

    Pali malingaliro ambiri ndi ma protocol omwe amakhudzidwa ndi ma network opanda zingwe. Kuti ndipatse aliyense lingaliro labwino, ndikufotokozerani zamagulu.

    1. Malinga ndi kufalikira kwa netiweki kosiyanasiyana, ma netiweki opanda zingwe atha kugawidwa kukhala:
    "WWAN" imayimira "network wide area network".
    "WLAN" imayimira Wireless Local Area Network.
    "WMAN" imayimira Wireless Metropolitan Area Network.
    "WPAN" imayimira maukonde opanda zingwe.


    Gulu la ma network opanda zingwe


    Mgwirizanowu ukuwonetsedwa mu chithunzi chotsatira:

    A wireless local area network (WLAN) ndi makina ochezera a pa Intaneti omwe amagwiritsa ntchito ukadaulo wolumikizirana opanda zingwe kulumikiza zida zosiyanasiyana zamakompyuta kuti apange netiweki yomwe imatha kulumikizana wina ndi mnzake, kutumiza deta, ndikugawana zothandizira. Muyezo wa IEEE 802.11 wama netiweki amdera lanu opanda zingwe amalola anthu kulumikizana opanda zingwe ku netiweki yapafupi ndi 2.4GHz kapena 5GHz wailesi frequency band mu band ya ISM, yomwe mwina siyiloledwa.
    Mawonekedwe: Imathandizira ogwiritsa ntchito zida zambiri, imakhala ndi kusinthasintha kwakukulu komanso kuyenda, ndipo sikumangokhala ndi chilengedwe chawaya.
    Ntchito zosiyanasiyana: lonse, monga mabizinesi, zipatala, masitolo, mafakitale, masukulu ndi mabanja.

    Ntchito yayikulu ya Wireless Metropolitan Area Network ndikulumikizana ndi msana ndikupereka chithandizo kwa ogwiritsa ntchito. Mwachitsanzo, wideband WMAN, yoyimiridwa ndi miyezo ya IEEE 802.16, imagwiritsidwa ntchito kwambiri polumikizira ma multipoint. Ukadaulo waukadaulo wopanda zingwe wama Metropolitan Area umatchedwanso "WiMAX Technology" pamsika. Unduna wa Zazidziwitso umakonza ma frequency awiri a 3.5 GHz (3400-3430mhz, 3500-3530mhz) ndi 5.8 GHz (5725-5850mhz) ngati magulu odzipatulira odzipatulira ofikira opanda zingwe kuma network amderali.
     
    A wireless wide area network (WWAN) ndi njira yolankhulirana yomwe imagwiritsa ntchito ma netiweki opanda zingwe kulumikiza ma network amderali (LANs) pamtunda wotalikirana kwambiri. Amagwiritsidwa ntchito makamaka ndi ogwira ntchito kuti aziphimba opanda zingwe. Muyezo wokhazikitsidwa ndi IEEE802.20.
    Zomwe zili pamwambazi ndizofotokozera za "gulu la ma network opanda zingwe" omwe amabweretsedwa ndiShenzhen Malingaliro a kampani 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.

    Tzinthu zolumikizirana zopangidwa ndi kampaniyo:

    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.Kukambirana ndipo kenako ntchito.
