802.11n inoda kutsanangurwa zvakasiyana.Parizvino, musika mukuru unoshandisa iyi protocol yeWiFi kutapurirana.
802.11n ndeye wireless transmission standard protocol.Iyo tekinoroji yekugadzira epoch.Chitarisiko chayo chinoita kuti chiyero chewireless network chiwedzere zvakanyanya.Kuti uvandudze maviri apfuura asina waya network zviyero, kusanganisira optimization yetiweki uye kushomeka kwetraffic kwe802.11a uye 802.11g.
Yayo yakanyanya kumhanyisa kumhanya ndeye 600 Mbit / s mudzidziso, asi haigone kusvika pakumhanya kwakadai mukuita nekuda kwezvakatipoteredza uye magadzirirwo zvinhu.Kuenzaniswa neiyo yapfuura 54mbit / s, inovandudzwa zvakanyanya uye kureba kwekutapurirana kuchawedzerwawo.
Boka rinoshanda reIEEE 802.11 rakagadzira boka rekutsvagisa repamusoro (HT) muna 2002 kuti riumbe chizvarwa chitsva chezviyero, uye yakashambadza zviri pamutemo chiyero che802.11n chakavakirwa paMIMO-OFDM muna 2009. Chinonyanya kukosha ndechekuti yakabudirira. muchiyero.
802.11 inotora akati wandei matekinoroji, ayo anounzira vashandisi nzvimbo itsva yechiitiko.Pasi peiyi protocol, indasitiri yeWLAN yakasimukira zvakanyanya, uye pfungwa yeWiFi yatora midzi.Kusvika ikozvino, nhamba huru ye802.11n zviteshi zvichiri kushandiswa mumambure.
802.11n tekinoroji inoona yakakura bandwidth uye inounza yakakura maficha ekushandisa kuWiFi.
802.11n yakaunza akawanda matekinoroji matsva.Muna 802.11n, kubuda kweWLAN tekinoroji inovandudzwa zvizere nekubatanidza optimization yemuviri layer uye MAC layer.MIMO yakagadzirwa neyemuviri layer tekinoroji yakakosha.MIMO-OFDM 40MHz uye pfupi GI tekinoroji inoshandiswa kuvandudza kubuda kweiyo yemuviri layer kusvika 600mbps.
GI inoreva kuti, nekuda kwekupesvedzera kweiyo multipath effect, ruzivo ruchafambiswa nenzira dzakawanda, dzinogona kudhumhana uye kutungamirira mukukanganiswa kweintersymbol.Nokuda kwechikonzero ichi, chiyero che 802.11a / g chinoda kuti pakutumira zviratidzo zvemashoko, panofanira kuva nenguva ye 0.8us pakati pezviratidzo zvemashoko, iyo inonzi nguva yevarindi.
Kuwedzera kune yemuviri layer optimization, 802.11n zvakare inogadzirisa iyo MAC protocol layer, uchishandisa block ACK, furemu aggregation, uye mamwe matekinoroji, ayo anovandudza zvakanyanya kushanda kweMAC.Iyo chete yemuviri layer inogadziriswa kana iyo MAC layer protocol isina kugadziridzwa.Zvakafanana nekugadzira mugwagwa wakapamhama, asi hausati uchimhanya pasina kuronga kwakanaka kwenzira.
Izvo zviri pamusoro ndiyo ieee802.11n ruzivo tsananguro yakaunzwa kwauriShenzhen HDV Phoelectron Technology Co., Ltd.Ndinovimba chinyorwa ichi chinogona kukubatsira iwe kuwedzera ruzivo rwako.Kunze kwechinyorwa ichi kana iwe uchitsvaga yakanaka optical fiber yekutaurirana michina yekugadzira kambani yaungafunganezvedu.
Zvigadzirwa zvekutaurirana zvinogadzirwa nekambani zvinovhara:
Module:optical fiber modules, Ethernet modules, Optical fiber transceiver modules, Optical fiber access modules, SSFP Optical modules,uyeSFP optical fibers, nezvimwewo.
ONU chikamu:EPON ONU, AC ONU, Optical fiber ONU, CATV ONU, GPON ONU, XPON ONU, nezvimwewo.

Izvo zviri pamusoro zvigadzirwa zvinogona kutsigira akasiyana network mamiriro.Kune zvigadzirwa zviri pamusoro, nyanzvi uye ine simba R & D timu yakapetwa kuti ipe rubatsiro rwehunyanzvi kune vatengi, uye inofunga uye inyanzvi bhizinesi timu inogona kupa emhando yepamusoro masevhisi evatengi 'kutanga.consultationuye gare gare kushanda.
