Kunemiqondo eminingi namaphrothokholi abandakanyekayo kumanethiwekhi angenawaya. Ukuze nginikeze wonke umuntu umbono ongcono, ngizochaza ukuhlukaniswa.
1. Ngokuhambisana nenethiwekhi ehlukene, amanethiwekhi angenawaya angahlukaniswa abe:
I-“WWAN” imele “inethiwekhi yendawo engenantambo.
I-"WLAN" imele i-Wireless Local Area Network.
“WMAN” imele iWireless Metropolitan Area Network.
I-“WPAN” imele inethiwekhi yendawo yomuntu siqu engenantambo.
Ubudlelwano buboniswa esithombeni esilandelayo:
Inethiwekhi yendawo engenantambo (i-WLAN) iwuhlelo lwenethiwekhi olusebenzisa ubuchwepheshe bokuxhumana obungenantambo ukuxhuma amadivaysi ekhompyutha ahlukene ukuze akhe isistimu yenethiwekhi engakwazi ukuxhumana yodwa, idlulise idatha, futhi yabelane ngezinsiza. Izinga le-IEEE 802.11 lamanethiwekhi endawo angenantambo livumela abantu ukuthi baxhume ngokungenantambo kunethiwekhi yendawo besebenzisa ibhendi yefrikhwensi yerediyo engu-2.4GHz noma engu-5GHz kubhendi ye-ISM, okungenzeka ingagunyaziwe.
Izici: Isekela abasebenzisi bamadivayisi amaningi, inokuguquguquka okuphezulu nokuhamba, futhi ayinqunyelwe indawo enezintambo.
Uhla lwezicelo: lubanzi kakhulu, njengamabhizinisi, izibhedlela, izitolo, izimboni, izikole nemindeni.
Umsebenzi oyinhloko wale nethiwekhi ye-Wireless Metropolitan Area ukuxhuma kumgogodla futhi uhlinzekele abasebenzisi. Isibonelo, i-wideband WMAN, emelwe amazinga ochungechunge e-IEEE 802.16, isetshenziswa kakhulu ekuxhumekeni kwamaphoyinti amaningi. Ubuchwepheshe benethiwekhi yendawo yedolobha elingenazintambo bubizwa nangokuthi “i-WiMAX Technology” emakethe. Umkhakha wolwazi uhlela amabhendi amabili efrikhwensi we-3.5 GHz (3400-3430mhz, 3500-3530mhz) kanye no-5.8 GHz (5725-5850mhz) njengamabhendi efrikhwensi azinikele okufinyelela okungenantambo kumanethiwekhi endawo yedolobha elikhulu.
Inethiwekhi yendawo ebanzi engenazintambo (i-WWAN) iyindlela yokuxhumana esebenzisa amanethiwekhi angenawaya ukuxhuma amanethiwekhi endawo (ama-LAN) ebangeni lenyama elihlakazeke kakhulu. Isetshenziswa kakhulu ama-opharetha ukumboza okungenantambo. Izinga elamukelwayo lithi IEEE802.20.
Okungenhla incazelo yolwazi "yokuhlukaniswa kwamanethiwekhi angenawaya" okulethwa yikhoI-Shenzhen I-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.
Timikhiqizo yokuxhumana ekhiqizwa ikhava yenkampani:
Imojuli: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.
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 eliqeqeshiwe nelinamandla limataniswe ukuze linikeze amakhasimende ukwesekwa kobuchwepheshe, futhi ithimba lebhizinisi elicabangayo nelichwepheshile linganikeza izinsizakalo zekhwalithi ephezulu kumakhasimende kusenesikhathi.Ukubonisana futhi kamuva umsebenzi.
