Funda kabanzi mayelana ne-IEEE 802.11a kuphrothokholi ye-WiFi, okuyiphrothokholi yokuqala yebhendi ye-5G.
1) Incazelo yephrothokholi:I-IEEE 802.11a iyindinganiso ebuyekeziwe engu-802.11 nezinga layo lokuqala, elavunywa ngo-1999. Iphrothokholi ewumongo yezinga le-802.11a iyafana nezinga lokuqala, kodwa imvamisa yayo yokusebenza ngu-5GHz, ama-52 orthogonal frequency division multiplexing subcarriers akhona. esetshenzisiwe, futhi isilinganiso sokuqala esiphezulu sokudluliswa kwedatha ngu-54Mb/s, okuyenza ihlangabezane nemfuneko yokuphuma okumaphakathi (20MB/s) yenethiwekhi yangempela.Yebo, uma kunesidingo, izinga ledatha lingehliswa libe ngu-48MB/s, 36MB/s, 24MB/s, 18MB/s, 12MB/s, 9MB/s, noma 6MB/s.I-802.11a inamashaneli angu-12 angadlulelani, okuyi-8 kuwo asetshenziswa endlini kanti amanye angu-4 asetshenziselwa ukudlulisela iphoyinti kuya ephuzwini.Ayikwazi ukusebenzisana ne-802.11b ngaphandle kwalapho kusetshenziswa idivayisi eyamukela womabili la mazinga.
2) IEEE 802.11a Okuhle nokubi:njengoba ibhendi ye-2.4G yayisetshenziswa kakhulu ngaleso sikhathi, yaya ngokuya igcwala.Ngakho-ke, ukusebenzisa i-5g band kuwukuthuthuka okubalulekile kwe-802.11a, okunokungqubuzana okumbalwa.Kodwa-ke, imvamisa ephezulu yenkampani yenethiwekhi nayo inemiphumela emibi.Ibanga lokudlulisela lingaphansi kuka-802.11b/g;ngokwengqondo, amasignali angu-5g avinjelwa kalula futhi amuncwa izindonga, ezifanele ukusakazwa komugqa oqondile nokungavinjelwanga, okuholela esidingweni sokusebenzisa amaphuzu amaningi okufinyelela.Ngakho-ke, ukufakwa kwe-802.11a kungaphansi kwalokho kuka-801.11b.I-802.11a izophinda ibangele izinkinga ngoba ubude bayo begagasi buzomuncwa izinto eziseduze, kwenze isignali yayo ibe buthakathaka futhi ibonakale nakakhulu ngokuhamba kwesikhathi.Kodwa-ke, njengoba zingeziningi izimpawu zokuphazamiseka eduze, ukuphuma kwe-802.11a ngokuvamile kuhle.
Okungenhla amaphuzu olwazi ephrothokholi ye-IEEE802.11a kanye nezinzuzo zayo kanye nokubi.
Okungenhla incazelo yolwazi ye-IEEE 802.11a elethwa 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:
Imojula: amamojula we-fiber optical, Amamojula we-Ethernet, amamojula we-fiber optical transceiver, amamojula okufinyelela kwefiber optical, Amamojula we-SSFP optical, futhiImicu ye-Optical SFP, njll.
Isigaba se-ONU: EPON ONU, AC ONU, i-fiber optical ONU, I-CATV ONU, I-GPON ONU, XPON ONU, njll.
Isigaba se-OLT: Ukushintsha kwe-OLT, I-GPON OLT, I-EPON OLT, ukuxhumana OLT, njll.
Imikhiqizo engenhla ingasekela izimo zenethiwekhi ezahlukahlukene.Kule mikhiqizo engenhla, ithimba le-R & D elichwepheshile nelinamandla limataniswe ukuze linikeze amakhasimende ukwesekwa kobuchwepheshe, futhi ithimba lebhizinisi elicabangayo nelichwepheshile linganikeza izinsizakalo zekhwalithi ephezulu kumakhasimende kusenesikhathi.ukubonisanafuthi kamuva umsebenzi.
