Funda ngakumbi malunga ne-IEEE 802.11a kwiprotocol ye-WiFi, eyiprotocol yokuqala yebhendi ye-5G.
1) Utoliko lweProtocol:IEEE 802.11a ngumgangatho ohlaziyiweyo we-802.11 kunye nomgangatho wayo wokuqala, owavunywa ngo-1999. I-protocol engundoqo yomgangatho we-802.11a iyafana nomgangatho wokuqala, kodwa i-frequency yayo yokusebenza yi-5GHz, i-52 orthogonal frequency division multiplexing subcarriers are esetyenzisiweyo, kwaye ubuninzi bezinga lothumelo lwedatha yi-54Mb / s, eyenza ukuba ihlangabezane nemfuno ye-medium throughput (20MB / s) yothungelwano lokwenene.Kakade ke, ukuba kuyimfuneko, izinga ledatha lingancitshiswa libe yi-48MB/s, 36MB/s, 24MB/s, 18MB/s, 12MB/s, 9MB/s, okanye 6MB/s.I-802.11a ineendlela ezili-12 ezingahambelaniyo, apho i-8 isetyenziselwa ngaphakathi kwaye enye i-4 isetyenziselwa ukuhanjiswa kwe-point-to-point.Ayikwazi ukusebenzisana ne-802.11b ngaphandle kokuba isixhobo esamkela zombini imigangatho sisetyenziswa.
2) IEEE 802.11a Izinto eziluncedo kunye nezingeloncedo:ekubeni ibhendi ye-2.4G yayisetyenziswa kakhulu ngelo xesha, yaya isanda.Ngoko ke, ukusebenzisa ibhendi ye-5g kuyiphuculo ebalulekileyo ye-802.11a, eneengxabano ezimbalwa.Nangona kunjalo, i-frequency carrier ephezulu ineziphumo ezibi.Umgama wothumelo ungaphantsi kwe-802.11b/g;ithiyori, imiqondiso ye-5g ivalwe ngokulula kwaye ifakwe kwiindonga, ezifanelekileyo kumgca othe ngqo kunye nokusasazwa okungathintekiyo, okukhokelela kwisidingo sokusebenzisa iindawo ezininzi zokufikelela.Ke ngoko, ukhuseleko lwe-802.11a lungaphantsi kolu-801.11b.I-802.11a nayo iya kubangela iingxaki kuba ubude bayo be-waveleng buya kutsalwa zizinto ezikufutshane, zenze uphawu lwayo lube buthathaka kwaye lubonakale ngakumbi ekuhambeni kwexesha.Nangona kunjalo, kuba kungekho miqondiso emininzi yokuphazamiseka ekufutshane, i-throughput ye-802.11a ilungile.
Oku kungasentla ngamanqaku olwazi lwe-IEEE802.11a protocol kunye nezinto eziluncedo kunye nezingeloncedo.
Oku kungentla yingcaciso yolwazi ye-IEEE 802.11a eziswe kuweShenzhen 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.
Udidi lwe-ONU: EPON ONU, AC ONU, ifayibha optical ONU, CATV ONU, GPON ONU, XPON ONU, njl.
iklasi yeOLT: Ukutshintsha OLT, GPON OLT, EPON OLT, unxibelelwano OLT, 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.
