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 ibhendi yefrikhwensi 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. Ngaphezu kwamazinga e-IEEE angenhla, 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 ye-fiber ongase uyicabangeleMayelana NATHI.
Imikhiqizo yokuxhumana ekhiqizwe yikhava yenkampani:
Imojuli: 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.
