Kukho iikhonsepthi ezininzi kunye neeprothokholi ezibandakanyekayo kwiinethiwekhi ezingenazingcingo.Ukuze ndinike wonke umntu umbono ongcono, ndiya kuchaza ulwahlulo.
1. Ngokuhambelana nenethiwekhi eyahlukeneyo, iinethiwekhi ezingenazingcingo zinokwahlulwa zibe:
“WWAN” imele “inethiwekhi yendawo ebanzi engenazingcingo.
"WLAN" imele iWireless Local Area Network.
“WMAN” imele iWireless Metropolitan Area Network.
"WPAN" imele inethiwekhi yendawo yomntu engenazingcingo.
Ubudlelwane buboniswa kulo mfanekiso ulandelayo:
Inethiwekhi yendawo engenazingcingo (WLAN) yinkqubo yenethiwekhi esebenzisa iteknoloji yonxibelelwano engenazingcingo ukuqhagamshela izixhobo ezahlukeneyo zekhompyuter ukwenza inkqubo yenethiwekhi ekwazi ukunxibelelana omnye komnye, idlulise idatha, kwaye yabelane ngezibonelelo.Umgangatho we-IEEE 802.11 wothungelwano lwengingqi olungenazingcingo luvumela abantu ukuba baqhagamshelane ngaphandle kwamacingo kuthungelwano lwendawo yasekuhlaleni besebenzisa i-2.4GHz okanye i-5GHz ibhendi yerediyo yerediyo kwibhendi ye-ISM, esenokungagunyaziswanga.
Iimpawu: Ixhasa abasebenzisi bezixhobo ezininzi, inokuguquguquka okuphezulu kunye nokuhamba, kwaye ayikhawulelwanga yindawo eneentambo.
Uluhlu lwezicelo: lubanzi kakhulu, njengamashishini, izibhedlele, iivenkile, iifektri, izikolo kunye neentsapho.
Owona msebenzi uphambili wale Wireless Metropolitan Area Network kukuqhagamshela kumqolo kunye nokubonelela ngokhuseleko kubasebenzisi.Umzekelo, i-wideband WMAN, emelwe yi-IEEE 802.16 series standards, isetyenziswa ikakhulu kuqhagamshelo lwamanqaku amaninzi.Itekhnoloji yenethiwekhi yendawo engenazingcingo ikwabizwa ngokuba yi "WiMAX Technology" kwimarike.I-Ofisi yoMphathiswa wolwazi icwangcisa iibhendi ezimbini zefrikhwensi ye-3.5 GHz (3400-3430mhz, 3500-3530mhz) kunye ne-5.8 GHz (5725-5850mhz) njengeebhendi zamaza ezinikezelweyo zokufikelela ngaphandle kwamacingo kuthungelwano lwengingqi yemetropolitan.
Inethiwekhi yendawo ebanzi engenazingcingo (WWAN) yindlela yonxibelelwano esebenzisa iinethiwekhi ezingenazingcingo ukuqhagamshela uthungelwano lwengingqi (LANs) kumgama othe saa ngokwasemzimbeni.Isetyenziswa ikakhulu ngabaqhubi ukugubungela ngaphandle kwamacingo.Umgangatho owamkelweyo yi-IEEE802.20.
Oku ngasentla yingcaciso yolwazi "yokuhlelwa kweenethiwekhi ezingenazintambo" eziziswaShenzhen 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.
Tiimveliso 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 zingasentla, iqela elinobuchule nelinamandla le-R & D lidityaniswe ukuze libonelele ngenkxaso yobugcisa kubathengi, kwaye iqela leshishini elicingayo nelinobuchule linokubonelela ngeenkonzo ezikumgangatho ophezulu kubathengi kwangethuba.Uthethwano kwaye emva komsebenzi.
