Impi yemizila yobuchwepheshe be-5G empeleni iyimpi yamabhendi amafrikhwensi.Njengamanje, umhlaba usebenzisa amabhendi amabili ahlukene wokuvama ukufaka amanethiwekhi e-5G, ibhande lokuvama phakathi kuka-30-300GHz libizwa nge-millimeter wave;enye ibizwa nge-Sub-6, egxile ku-3GHz-4GHz frequency band.
Kuncike ezicini ezibonakalayo zamaza omsakazo, ubude begagasi obufushane kanye nezici zemishayo emincane yamagagasi angamamilimitha zivumela ukulungiswa kwesignali, ukuphepha kokudlulisela, kanye nesivinini sokudlulisela ukuthi kuthuthukiswe, kodwa ibanga lokudlulisela lehliswa kakhulu.
Ngokusho kokuhlolwa kokufakwa kwe-5G ye-Google yobubanzi obufanayo kanye nenani elifanayo leziteshi eziyisisekelo, inethiwekhi ye-5G esetshenziswe ngamagagasi amamilimitha ingamboza u-11.6% wabantu ngesilinganiso esingu-100Mbps, kanye no-3.9% ngesilinganiso se-1Gbps.Inethiwekhi ye-6-band 5G, inethiwekhi yezinga le-100Mbps ingamboza u-57.4% wabantu, futhi izinga le-1Gbps lingamboza u-21.2% wabantu.
Kungabonakala ukuthi ukumbozwa kwamanethiwekhi e-5G asebenza ngaphansi kwe-Sub-6 kungaphezu kwezikhathi ezi-5 zamaza amamilimitha.Ngaphezu kwalokho, ukwakhiwa kweziteshi ze-millimeter wave kudinga ukufakwa kwezigidi ezingu-13 ezigxotsheni zensiza, okuzobiza amaRandi ayizigidi eziyizinkulungwane ezingu-400, ukuze kuqinisekiswe ukumbozwa kwe-72% ku-100 Mbps ngomzuzwana ebhendi ye-28GHz futhi cishe i-55 ngomzuzwana ku-1Gbps.% ukufakwa.I-Sub-6 idinga kuphela ukufaka isiteshi sesisekelo se-5G esiteshini sokuqala se-4G, esisindisa kakhulu izindleko zokuthumela.
Ukusuka ekumbozweni kuya ezindlekweni zokusetshenziswa kwezentengiso, i-Sub-6 iphakeme kune-mmWave esikhathini esifushane.
Kodwa isizathu siwukuthi izinsiza ze-spectrum ziningi, umkhawulokudonsa wenethiwekhi ungafinyelela ku-400MHz / 800MHz, futhi izinga lokudlulisa okungenantambo lingafinyelela ngaphezu kwe-10Gbps;okwesibili ugongolo lwegagasi oluwumngcingo lwemilimitha, isiqondiso esihle, kanye nokulungiswa kwendawo okuphakeme kakhulu;okwesithathu izingxenye zamaza ama-millimeter-Wave Uma kuqhathaniswa nemishini ye-Sub-6GHz, kulula ukuyenza ibe mincane.Okwesine, isikhawu senkampani yenethiwekhi sikhulu, futhi isikhathi se-SLOT esisodwa (120KHz) singu-1/4 wefrikhwensi ephansi ye-Sub-6GHz (30KHz), futhi ukubambezeleka kokusebenzelana komoya kuyehlisiwe.Kuzinhlelo zokusebenza zenethiwekhi yangasese, inzuzo ye-millimeter wave icishe iphule i-Sub-6.
Njengamanje, inethiwekhi yangasese yokuxhumana yemoto-yomhlaba esetshenziswa ukuxhumana kwe-millimeter-wave embonini yezokuthutha zesitimela ingafinyelela izinga lokudlulisela le-2.5Gbps ngaphansi kwe-high-speed dynamic, futhi ukubambezeleka kokudlulisela kungafinyelela ku-0.2ms, enenani eliphezulu kakhulu. yokunyuswa kwenethiwekhi yangasese.
Kumanethiwekhi ayimfihlo, izimo ezifana nezokuthutha zikaloliwe nokuqapha ukuphepha komphakathi zinganikeza ukudlala okuphelele kuzinzuzo zobuchwepheshe zamaza amamilimitha ukuze kuzuzwe isivinini sangempela se-5G.
