    IEEE 802.11b/IEEE 802.11g Sharaxaada Habmaamuuska

    Waqtiga boostada: Sebtembar-01-2022

    1. IEEE802.11b iyo IEEE802.11g labadaba waxaa loo isticmaalaa xadiga soo noqnoqda ee 2.4GHz. Aynu si joogto ah u sharaxno labadan hab-maamuus si aynu u fahanno halbeegyada hab-maamuusyada kala duwan.

    IEEE 802.11b waa halbeeg loogu talagalay shabakadaha aagga wirelesska. Inta jeer ee qaaduhu waa 2.4GHz, waxayna ku siin kartaa xawli gudbineed badan oo ah 1, 2, 5.5, iyo 11 mbit/s, ilaa 11 mbit/s. Wakhtigeeda sii dayntu waa 5 jeer ka dhakhso badan heerka IEEE 802.11 ee hadda la ansixiyay laba sano ka hor, kaas oo balaariyay goobta codsiga ee shabakadaha aagga wirelesska iyo bixinta taageerada aasaasiga ah ee heerarka gudbinta sare. Isticmaalka, xajiyeyaasha kala duwan ee 5.5 Mbps, 2 Mbps, iyo 1 Mbps ayaa loo isticmaali karaa iyadoo loo eegayo xaaladda dhabta ah. Imtixaanka dhabta ah ka dib, xawaaraha shaqadu wuxuu ku saabsan yahay 5 MB/s, kaas oo ku dhow inuu la mid yahay kan caadiga ah ee 10Base-T cable LAN. Qeybta ISM ee 2.4GHz, waxaa jira 11 kanaal oo leh bandwidth 22mhz ah oo la heli karo, kuwaas oo ah 11 band oo is dul saaran. Halbeegga ka dambeeya ee IEEE 802.11b waa IEEE 802.11g.
     
    2. IEEE 802.11g waxa la ansixiyay July 2003 Xawaaraha gudbinta asalka ah waa 54 Mbit/s, xawaaraha gudbinta saafiga ahna waa qiyaastii 24.7 Mbit/s (oo la mid ah 802.11a). Qalabka 802.11g wuxuu hoos ugu socdaa 802.11b.
     
    Tan iyo markaas, qaar ka mid ah wirelessrouterwarshadeeyayaashu waxay soo saareen heerar cusub oo ku salaysan heerka IEEE 802.11g si ay u daboolaan baahida suuqa waxayna kordhiyeen xawaaraha gudbinta aragtida ilaa 108 mbit/s ama 125 mbit/s. Hadda, waxaa jira borotokool la-socod sida IEEE 802.ax oo ku lug leh WiFi 6 ama wixii ka sareeya, kuwaas oo dhamaantood lagu hagaajiyay lakabka PHY si loo kordhiyo xawaaraha in ka badan Gigabit, markaa kama hadli doono halkan.

    Sawirka soo socdaa waa koobitaanka IEEE802.11a IEEE802.11b IEEE802.11g:

    Tan sare waa sharraxaadda aqoonta ee IEEE 802.11b/IEEE 802.11g uu keenayShenzhen HDV Phoelectron Technology Co., Ltd. Waxaan rajeynayaa in maqaalkani uu kaa caawin doono inaad kordhiso aqoontaada. Maqaalkan ka sokow haddii aad raadinayso shirkad soo saarta qalabka isgaarsiinta fiber indhaha oo wanaagsan waxaad tixgelin kartaanagu saabsan.

    Alaabooyinka isgaadhsiinta ee ay shirkadu soo saartay waxa ay dabooshaa:

    Module:modules fiber indhaha, modules Ethernet, modules transceiver fiber indhaha, modules helitaanka fiber indhaha, SSFP modules indhahaiyoFiber indhaha ee SFPiwm.
    ONUqaybta:EPON ONU, AC ONU, fiber optic ONU, CATV ONU, GPON ONU, XPON ONUiwm.
    OLTfasalka:beddelka OLT, GPON OLT, EPON OLT, isgaarsiintaOLTiwm.

    Alaabooyinka kor ku xusan waxay taageeri karaan xaalado shabakadeed oo kala duwan. Alaabooyinka kor ku xusan, kooxda R & D ee xirfadleyda ah iyo xoogga leh ayaa lagu lammaaniyaa si ay taageero farsamo u siiyaan macaamiisha, iyo koox ganacsi oo fikir iyo xirfad leh ayaa bixin kara adeegyo tayo sare leh oo macaamiisha ah goor hore.la tashikadibna shaqada.
