Kuri protocole ya IEEE802.11 muri WiFi, hakorwa umubare munini wibibazo byamakuru, kandi iterambere ryamateka ryavuzwe muri make kuburyo bukurikira. Inshamake ikurikira ntabwo ari inyandiko yuzuye kandi irambuye, ahubwo ni ibisobanuro bya protocole ikoreshwa ku isoko.
IEEE 802.11, yashinzwe mu 1997, ni igipimo cyambere (2Mbit / s, cyatangajwe kuri 2.4GHz). Umuvuduko wacyo uratinda cyane, ushyiraho urufatiro rwa protocole idafite umugozi.
IEEE 802.11a yashyizweho mu 1999. Igamije kuzuza urwego rwumubiri (54mbit / s naho umurongo wa radiyo ni 5GHz).
IEEE 802.11b, yashyizweho mu 1999, ni inyongera ku gipimo cya 2.4GHz cyatanzwe na 11 (11mbit / s, cyatangajwe kuri 2.4GHz).
IEEE 802.11g, 2003, inyongera yumubiri (54 mbit / s, 2.4GHz isakaza).
IEEE 802.11n. Igipimo cyo kohereza cyateye imbere muri iyi protocole. Igipimo cyibanze cyiyongereye kuri 72.2 mbit / s, kandi umurongo wa kabiri wa 40 MHz urashobora gukoreshwa. Icyo gihe, igipimo cyariyongereye kugera kuri mbit / s 150. Inkunga yo kwinjiza byinshi, gusohora byinshi (MIMO) tekinoroji. Porotokole ifatanya kunoza umurongo wa interineti hagati ya 2.4GHz na 5GHz.
IEEE 802.11ac, ushobora kuzasimbura 802.11n, ni ugutezimbere umuvuduko mwinshi. Iyo sitasiyo nyinshi zifatizo zikoreshwa, igipimo cyitumanaho cyongerewe byibuze kuri 1 Gbps kandi igipimo cyumuyoboro umwe cyiyongera byibuze 500 Mbps. Koresha umurongo mwinshi utagikoreshwa (80 Mhz-160 MHz, ugereranije na 802.11n ya 40 MHz), imigezi myinshi ya MIMO (kugeza 8), nuburyo bwiza bwo guhindura (QAM256). Ibipimo byemewe byatangijwe ku ya 18 Gashyantare 2012.
Muri byo, hari protocole idasanzwe. Usibye ibipimo byavuzwe haruguru bya IEEE, ubundi buhanga bwitwa IEEE 802.11b + butanga igipimo cyo kohereza amakuru ya 22mbit / s hashingiwe kuri IEEE 802.11b (bande 2.4GHz) binyuze mu ikoranabuhanga rya pBCC.
Ibyavuzwe haruguru nubusobanuro bwubumenyi bwa IEEE 802.11 urutonde rusanzwe rwazanwe naShenzhen 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,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 ryatekerejweho kandi ryumwuga rirashobora gutanga serivise nziza zo kugisha inama abakiriya hakiri kare hanyuma bagakora nyuma.
