Kwa protocol ya IEEE802.11 mu WiFi, mafunso ambiri amachitidwe amachitidwa, ndipo chitukuko cha mbiriyakale chikufotokozedwa mwachidule motere.Chidule chotsatirachi si mbiri yokwanira komanso yatsatanetsatane, koma kufotokozera ma protocol omwe amagwiritsidwa ntchito pamsika.
IEEE 802.11, yomwe idakhazikitsidwa mu 1997, ndiye muyeso woyambirira (2Mbit/s, kuwulutsa pa 2.4GHz).Kuthamanga kwake kumakhala kochepa, komwe kumayala maziko a ma protocol opanda zingwe.
IEEE 802.11a inapangidwa mu 1999. Cholinga chake ndi kuwonjezera gawo la thupi (54mbit / s ndi gulu lafupipafupi ndi 5GHz).
IEEE 802.11b, yopangidwa mu 1999, ndiyowonjezera ku 2.4GHz yosanjikiza yopangidwa ndi 11 (11mbit/s, kuwulutsa pa 2.4GHz).
IEEE 802.11g, 2003, zowonjezera zowonjezera zakuthupi (54 mbit/s, 2.4GHz broadcast).
IEEE 802.11n.Mlingo wotumizira wapita patsogolo pansi pa protocol iyi.Mlingo woyambira ukuwonjezeka mpaka 72.2 mbit/s, ndipo bandwidth iwiri ya 40 MHz ingagwiritsidwe ntchito.Panthawiyo, mlingowo unawonjezeka kufika pa 150 mbit / s.Thandizo laukadaulo wazinthu zambiri, zotulutsa zambiri (MIMO).Protocol iyi imathandizira ma frequency band pakati pa 2.4GHz ndi 5GHz.
IEEE 802.11ac, yemwe angalowe m'malo mwa 802.11n, ndiye kupititsa patsogolo kufalikira kwapamwamba.Mukamagwiritsa ntchito masiteshoni angapo, kuchuluka kwa opanda zingwe kumachulukitsidwa mpaka 1 Gbps ndipo njira imodzi imakulitsidwa mpaka 500 Mbps.Gwiritsani ntchito ma bandwidth apamwamba opanda zingwe (80 Mhz-160 MHz, poyerekeza ndi 802.11n's 40 MHz), mitsinje yambiri ya MIMO (mpaka 8), komanso mawonekedwe abwinoko (QAM256).Muyezo wovomerezeka unakhazikitsidwa pa February 18, 2012.
Pakati pawo, pali protocol yapadera.Kuphatikiza pa miyezo yomwe ili pamwambayi ya IEEE, ukadaulo wina wotchedwa IEEE 802.11b + umapereka kuchuluka kwa data 22mbit/s kutengera IEEE 802.11b (2.4GHz band) kudzera muukadaulo wa pBCC.
Zomwe zili pamwambazi ndikulongosola kwa chidziwitso cha mndandanda wa IEEE 802.11 wobweretsedwa 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,SSFP Optical modules,ndiSFP kuwala ulusi, ndi zina.
Gulu la ONU: EPON ONU, AC ONU, Optical fiber ONU, CATV ONU, GPON ONU, XPON PA, ndi zina.
kalasi ya OLT: Kusintha kwa mtengo wa OLT, Mtengo wa GPON OLT, EPON OLT, kulankhulana OLT, etc.
Zomwe zili pamwambazi zimatha kuthandizira zochitika zosiyanasiyana zapaintaneti.Pazinthu zomwe zili pamwambazi, 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 pakukambilana kwamakasitomala koyambirira komanso ntchito pambuyo pake.
