1. IEEE802.11b kunye ne-IEEE802.11g zombini zisetyenziswa kwi-2.4GHz band frequency. Makhe sichaze ezi prothokholi zimbini ngendlela eqhubekayo ukuze siqonde imigangatho yeeprothokholi ezahlukeneyo.
IEEE 802.11b ngumgangatho wothungelwano lwengingqi olungenazingcingo. I-frequency carrier yayo yi-2.4GHz, kwaye inokubonelela ngesantya sothumelo oluninzi lwe-1, 2, 5.5, kunye ne-11 mbit / s, ukuya kwi-11 mbit / s. Ixesha lalo lokukhululwa liphindwe ka-5 ngokukhawuleza kunomgangatho we-IEEE 802.11 osanda kuvunywa kwiminyaka emibini edlulileyo, eyandise intsimi yesicelo sothungelwano lwengingqi olungenacingo kunye nokubonelela ngenkxaso eyisiseko kumazinga aphezulu okudluliselwa. Ukusetyenziswa, i-bandwidths eyahlukeneyo ye-5.5 Mbps, i-2 Mbps, kunye ne-1 Mbps ingasetyenziselwa ngokwemeko yangempela. Emva kovavanyo lwangempela, isantya esisebenzayo simalunga ne-5 MB / s, ephantse ibe kumgangatho ofanayo ne-10Base-T cable ye-LAN eqhelekileyo. Kwibhendi ye-ISM ye-2.4GHz, kukho iziteshi ze-11 ezine-bandwidth ye-22mhz ekhoyo, eziyi-11 ezihambelanayo. Umgangatho wokulandela kwi-IEEE 802.11b yi-IEEE 802.11g.
2. IEEE 802.11g yamkelwa ngoJulayi 2003. I-frequency carrier yi-2.4GHz (efana ne-802.11b), kwaye kukho i-14 frequency bands. Isantya transmission original yi 54 Mbit / s, kwaye isantya transmission umnatha malunga 24.7 Mbit / s (efana 802.11a). Isixhobo se-802.11g sisezantsi sihambelana ne-802.11b.
Ukususela ngoko, ezinye wirelessumzilaabavelisi baphuhlise imigangatho emitsha esekelwe kumgangatho we-IEEE 802.11g ukuhlangabezana neemfuno zemarike kwaye bandise isantya sothumelo lwethiyori ukuya kwi-108 mbit/s okanye i-125 mbit/s. Okwangoku, kukho iiprothokholi zokulandelela ezifana ne-IEEE 802.ax ebandakanya i-WiFi 6 okanye ngaphezulu, zonke zilungiswe kwi-PHY layer ukunyusa isantya ukuya ngaphezu kwe-Gigabit, ngoko asiyi kuxoxa ngazo apha.
Lo mfanekiso ulandelayo sisishwankathelo se-IEEE802.11a IEEE802.11b IEEE802.11g:
Oku kungasentla yingcaciso yolwazi lwe-IEEE 802.11b/IEEE 802.11g eziswa nguShenzhen HDV Phoelectron Technology Co., Ltd. ndiyathemba ukuba eli nqaku linokukunceda ukwandisa ulwazi lwakho. Ngaphandle kweli nqaku ukuba ujonge inkampani elungileyo yomenzi wezixhobo zonxibelelwano lwefiber onokuthi uyithathele ingqalelongathi.
Iimveliso zonxibelelwano eziveliswe yikhava yenkampani:
Imodyuli:iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl.
I-ONUudidi:EPON ONU, AC ONU, ifayibha optical ONU, CATV ONU, GPON ONU, XPON ONU, njl.
OLTiklasi:Ukutshintsha OLT, GPON OLT, EPON OLT, unxibelelwanoOLT, njl.
Ezi mveliso zingentla zinokuxhasa iimeko ezahlukeneyo zenethiwekhi. Kwezi mveliso zingentla, iqela elinobuchule nelinamandla le-R & D lidityaniswe ukuze libonelele ngenkxaso yobugcisa kubathengi, kwaye iqela loshishino elicingayo nelinobuchule linokubonelela ngeenkonzo ezikumgangatho ophezulu kubathengi kwangethuba.ukubonisanakwaye emva komsebenzi.
