Kuphrothokholi ye-IEEE802.11 ku-WiFi, inani elikhulu lemibuzo yedatha liyaqhutshwa, futhi ukuthuthukiswa komlando kufinyezwa kanje. Isifinyezo esilandelayo akulona irekhodi eliphelele nelinemininingwane, kodwa incazelo yemithetho esetshenziswa njengamanje emakethe.
I-IEEE 802.11, eyasungulwa ngo-1997, iyindinganiso yokuqala (2Mbit/s, esakazwa ku-2.4GHz). Ijubane layo lihamba kancane, okwenza isisekelo samaphrothokholi angenantambo.
I-IEEE 802.11a yakhiwe ngo-1999. Ihloselwe ukwengeza isendlalelo esibonakalayo (54mbit/s kanye nebhendi yefrikhwensi ingu-5GHz).
I-IEEE 802.11b, eyakhiwe ngo-1999, iyisengezo sesendlalelo esibonakalayo esingu-2.4GHz esihlongozwe ngo-11 (11mbit/s, esisakazwa ngo-2.4GHz).
IEEE 802.11g, 2003, isithasiselo sesendlalelo esibonakalayo (54 mbit/s, ukusakaza okungu-2.4GHz).
IEEE 802.11n. Izinga lokudlulisela lithuthukile ngaphansi kwale phrothokholi. Izinga eliyisisekelo likhuphukela ku-72.2 mbit/s, futhi umkhawulokudonsa ophindwe kabili we-40 MHz ungasetshenziswa. Ngaleso sikhathi, izinga lenyuswe laya ku-150 mbit/s. Ukusekela okokufaka okuningi, ubuchwepheshe be-multi-output (MIMO). Le phrothokholi ngokuhlanganyela ithuthukisa ibhande lokuvama phakathi kuka-2.4GHz no-5GHz.
I-IEEE 802.11ac, okungaba umlandeli we-802.11n, ukuthuthukiswa kwezinga eliphezulu lokudlulisela. Uma kusetshenziswa iziteshi eziningi eziyisisekelo, izinga lokungenantambo liyakhuphuka libe okungenani ngu-1 Gbps futhi izinga lesiteshi esisodwa liyakhuphuka libe okungenani ku-500 Mbps. Sebenzisa umkhawulokudonsa ongenantambo ophezulu (80 Mhz-160 MHz, uma uqhathaniswa no-802.11n's 40 MHz), ukusakaza okwengeziwe kwe-MIMO (kufika ku-8), kanye nemodi yokumodeshi engcono (QAM256). Izinga elisemthethweni lethulwe ngoFebhuwari 18, 2012.
Phakathi kwabo, kukhona iphrothokholi ekhethekile. Ngokungeziwe kumazinga angenhla e-IEEE, obunye ubuchwepheshe obubizwa nge-IEEE 802.11b + buhlinzeka ngezinga lokudluliswa kwedatha elingu-22mbit/s ngokusekelwe ku-IEEE 802.11b (2.4GHz band) ngobuchwepheshe be-pBCC.
Okungenhla yincazelo yolwazi yohlu olujwayelekile lwe-IEEE 802.11 olethwe kuwenaI-Shenzhen HDV Phoelectron Technology Co., Ltd.ngethemba ukuthi lesi sihloko singakusiza ukukhulisa ulwazi lwakho. Ngaphandle kwalesi sihloko uma ufuna inkampani enhle yabakhiqizi bemishini yokuxhumana yefiber ongase uyicabangeleMayelana NATHI.
Imikhiqizo yokuxhumana ekhiqizwe yikhava yenkampani:
Imojula: amamojula we-fiber optical, Amamojula we-Ethernet, amamojula we-fiber optical transceiver,Amamojula we-SSFP optical, futhiImicu ye-Optical SFP, njll.
I-ONUisigaba: EPON ONU, AC ONU, i-fiber optical ONU, I-CATV ONU, I-GPON ONU, XPON ONU, njll.
OLTisigaba: Ukushintsha kwe-OLT, I-GPON OLT, I-EPON OLT, ukuxhumanaOLT, njll.
Imikhiqizo engenhla ingasekela izimo zenethiwekhi ezahlukahlukene. Kule mikhiqizo engenhla, ithimba le-R & D elichwepheshile nelinamandla limataniswe ukuze linikeze ukwesekwa kobuchwepheshe kumakhasimende, futhi ithimba lebhizinisi elicabangayo nelichwepheshile lingahlinzeka ngamasevisi ekhwalithi ephezulu ukuze kuboniswane namakhasimende kusenesikhathi kanye nomsebenzi wakamuva.
