Wige byinshi kuri IEEE 802.11a muri protocole ya WiFi, niyo protocole ya mbere ya 5G.
1) Ibisobanuro bya protocole:IEEE 802.11a ni igipimo cyavuguruwe cya 802.11 hamwe n’umwimerere wacyo, cyemejwe mu 1999. Porotokole yibanze y’urwego 802.11a ni kimwe n’umwimerere wambere, ariko inshuro zayo ni 5GHz, 52 ya orthogonal frequency division multiplexing subcarrier ni ikoreshwa, kandi igipimo ntarengwa cyo kohereza amakuru ni 54Mb / s, bigatuma cyuzuza ibisabwa byinjira hagati (20MB / s) y'urusobe nyarwo. Nibyo, nibiba ngombwa, igipimo cyamakuru gishobora kugabanuka kugera kuri 48MB / s, 36MB / s, 24MB / s, 18MB / s, 12MB / s, 9MB / s, cyangwa 6MB / s. 802.11a ifite imiyoboro 12 idahuzanya, muri yo 8 ikoreshwa mu nzu naho izindi 4 zikoreshwa mu guhererekanya ingingo. Ntishobora gukorana na 802.11b keretse niba igikoresho cyemeza ibipimo byombi cyakoreshejwe.
2) IEEE 802.11a Ibyiza n'ibibi:kubera ko itsinda rya 2.4G ryakoreshwaga cyane muri kiriya gihe, ryarushijeho kuba ryinshi. Kubwibyo, gukoresha bande ya 5g niterambere ryingenzi rya 802.11a, rifite amakimbirane make. Nyamara, inshuro nyinshi zitwara ibintu nazo zigira ingaruka mbi. Intera yo kohereza iri munsi ya 802.11b / g; mubyukuri, ibimenyetso 5g byoroshye gufungwa no kwinjizwa nurukuta, bikwiranye no kugororoka kumurongo no gukwirakwizwa ntakabuza, biganisha ku gukenera gukoresha ahantu henshi. Kubwibyo, gukwirakwiza 802.11a ntabwo biri munsi ya 801.11b. 802.11a nayo izatera ibibazo kuko uburebure bwumurongo wabwo buzakirwa nibikoresho byegeranye, bigatuma ibimenyetso byayo bigabanuka kandi bikagaragara mugihe runaka. Ariko, kubera ko nta bimenyetso byinshi byo kwivanga hafi, ibyinjira muri 802.11a muri rusange ni byiza.
Ibyavuzwe haruguru nubumenyi bwubumenyi bwa IEEE802.11a protocole nibyiza byayo nibibi.
Ibyavuzwe haruguru nubusobanuro bwubumenyi bwa IEEE 802.11a yazanwe naweShenzhen HDV Phoelectron Technology Co., Ltd.. twizere ko iyi ngingo ishobora kugufasha kongera ubumenyi. Usibye iyi ngingo niba ushaka ibikoresho byiza bya fibre itumanaho ibikoresho bya sosiyete ushobora gutekerezaibyerekeye twe.
Ibicuruzwa byitumanaho byakozwe nisosiyete ikora:
Module: moderi ya fibre optique, Ethernet, optique fibre transceiver modules, optique ya fibre optique, SSFP optique module, naSFP optique, n'ibindi.
ONUicyiciro: EPON ONU, AC ONU, fibre optique ONU, CATV ONU, GPON ONU, XPON ONU, n'ibindi.
OLTicyiciro: OLT, GPON OLT, EPON OLT, itumanahoOLT, n'ibindi.
Ibicuruzwa byavuzwe haruguru birashobora gushigikira imiyoboro itandukanye. Kubicuruzwa byavuzwe haruguru, itsinda ryumwuga kandi rikomeye R & D ryahujwe no gutanga ubufasha bwa tekinike kubakiriya, kandi itsinda ryubucuruzi ryatekereje kandi ryumwuga rirashobora gutanga serivise nziza kubakiriya hakiri karekugisha inamahanyuma nyuma.
