Dzidza zvakawanda nezveIEEE 802.11a muWiFi protocol, inova yekutanga 5G bhendi protocol.
1) Kududzirwa kweProtocol:IEEE 802.11a chiyero chakadzokororwa che802.11 uye chiyero chayo chepakutanga, icho chakabvumirwa muna 1999. The core protocol ye802.11a chiyero yakafanana neyekutanga, asi kushanda kwayo nguva ndeye 5GHz, 52 orthogonal frequency division multiplexing subcarriers vari. yakashandiswa, uye huwandu hwekutanga hwekutumira data ndeye 54Mb / s, izvo zvinoita kuti zvisangane nezvinodiwa zvepakati throughput (20MB/s) yetiweki chaiyo.Zvechokwadi, kana zvichidiwa, nhamba yedata inogona kuderedzwa kusvika 48MB/s, 36MB/s, 24MB/s, 18MB/s, 12MB/s, 9MB/s, kana 6MB/s.802.11a ine 12 migero isingapindirane, iyo 8 inoshandiswa mukati meimba uye imwe 4 inoshandiswa pakunongedza-ku-point.Haikwanise kupindirana ne802.11b kunze kwekunge mudziyo unotora zviyero zviviri uchishandiswa.
2) IEEE 802.11a Zvakanakira uye zvazvakaipira:sezvo bhendi re2.4G raishandiswa zvakanyanya panguva iyoyo, rakawedzera kuwanda.Nokudaro, kushandisa 5g band ndiko kuvandudzwa kwakakosha kwe802.11a, iyo ine mhirizhonga shoma.Nekudaro, iyo yakakwira inotakura frequency inewo yakaipa mhedzisiro.Iyo yekufambisa kureba iri pasi pe802.11b/g;ne theoretically, zviratidzo zve 5g zviri nyore kuvharidzirwa uye zvinoputirwa nemadziro, izvo zvakakodzera mutsara wakatwasuka uye usina kuvharidzirwa kupararira, izvo zvinotungamirira kudiwa kwekushandisa mamwe mapeji ekuwana.Naizvozvo, kufukidzwa kwe802.11a ishoma pane iyo ye801.11b.802.11a ichakonzerawo matambudziko nekuti urefu hwayo huchatorwa nezvinhu zviri padyo, zvichiita kuti chiratidzo chayo chiite zinyekenyeke uye chiwedzere kuoneka nekufamba kwenguva.Nekudaro, sezvo pasina akawanda ekukanganisa masaini padyo, iyo throughput ye802.11a kazhinji yakanaka.
Izvo zviri pamusoro ndiwo mapoinzi eruzivo eIEEE802.11a protocol uye zvakanakira nekuipira.
Izvo zviri pamusoro ndiyo tsananguro yeruzivo yeIEEE 802.11a 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.
OLT kirasi: kuchinja OLT, GPON OLT, EPON OLT, kutaurirana OLT, nezvimwewo.
Izvo zviri pamusoro zvigadzirwa zvinogona kutsigira akasiyana network mamiriro.Kune zvigadzirwa zviri pamusoro, nyanzvi uye ine simba R & D timu yakapetwa kuti ipe rutsigiro rwehunyanzvi kune vatengi, uye inofunga uye inyanzvi bhizinesi timu inogona kupa emhando yepamusoro masevhisi evatengi 'kutanga.consultationuye gare gare kushanda.
