Qonda i-5G Network.

Icala elingenazingcingo:  

iiselfowuni okanye abathengi beqela baqhagamshelwe kuthungelwano lofikelelo olungenazingcingo ngesikhululo esisisiseko.Kwicala lenethiwekhi yokufikelela, ziyakwazi ukusombululwa nge-RTN, i-ipran okanye i-PTN izisombululo, ukuhambisa iimpawu kwi-BSC / RNC, kunye nokudlulisa iimpawu kwinethiwekhi engundoqo, apho izinto zenethiwekhi ngaphakathi kwenethiwekhi engundoqo ziqhutyelwa nge-IP Bearer Network.

 

Icala lomnatha olungisiweyo:  

abathengi basekhaya kunye nabathengi baqhagamshelwe ngenethiwekhi yofikelelo, eyona nto iyi-GPON, kubandakanya i-ont, i-ODN kunye ne-OLT.Emva kokuba umqondiso uphuma kwinethiwekhi yokufikelela, ingena kwindoda.Indoda inokohlulwa ibe umaleko wofikelelo, umaleko odityanisiweyo kunye nomaleko ongundoqo.I-Bras yindlela yokungena yendoda, esetyenziselwa kakhulu ukuqinisekiswa, ukuqinisekiswa kunye nokuhlawula.Emva kokuba umqondiso uphuma kwindoda, ifikelela kwinethiwekhi yomqolo.Kwinethiwekhi yomqolo, inokwahlulwa ibe umaleko wofikelelo kunye nomgangatho ongundoqo.Phakathi kwabo, i-China Mobile yi-cmnet, i-China Telecom yi-169 kunye ne-China Unicom yi-163.

 

Icala lothungelwano olusisigxina kunye necala elingenazingcingo linokuhanjiswa ngefiber optical.Ukuhanjiswa komgama omde kwenziwa ikakhulu ziimveliso zeWavelength Division.Iimveliso zokwahlula amaza ubukhulu becala zithwala inani elikhulu leempawu ngoguqulelo oluphuculweyo lwe-WDM + SDH.I-OTN yinkqubo yokupakisha yomqondiso.Ngolu phawu lokupakisha, lunokuhanjiswa ngcono kwinkqubo yolwahlulo lwamaza.

 

Emva kokufunda i-macro structure, masingene nzulu kwindawo nganye kwaye siyifunde nzulu.

 

Ufikelelo womnatha womnatha, oqhele ukubizwa ngokuba yi-ran (inethiwekhi yokufikelela kwirediyo).Ngamafutshane, zonke iitheminali ezihambayo ziqhagamshelwe kwinethiwekhi kwinethiwekhi yonxibelelwano.Isikhululo esisisiseko esaziwayo sisenethiwekhi yokufikelela kwirediyo (RAN).

 

 

Isikhululo esingenazingcingo

 

 

Ukuphuculwa kwemigangatho yonxibelelwano akukho nto ngaphandle kokutshintsha igama okanye indawo yesixhobo, kwaye i-essence essence ayitshintshanga.  Kuyafana nakwinkqubo yesitishi esisisiseko kunye nenkqubo yonke yokufikelela kwinethiwekhi engenazingcingo.Isikhululo esisisiseko sidla ngokubandakanya i-BBU (ingakumbi enoxanduva lokumodareyitha umqondiso), i-RRU (ingakumbi inoxanduva lokusetyenzwa kweRF), i-feeder (idibanisa i-RRU kunye ne-eriyali), kunye ne-eriyali (ingakumbi enoxanduva lokuguqulwa phakathi kwamaza akhokelwayo kwintambo kunye ne-space wave emoyeni).
