Ubuchwepheshe be-I. MIMO (Multiple Input Multiple Output) buthuthukisa ukuxhumana okungenantambo ngokusebenzisa ama-antenna amaningi kokubili ku-transmitter kanye ne-receiver. Bunikeza izinzuzo ezibalulekile njengokwanda kokudluliselwa kwedatha, ukumbozwa okwandisiwe, ukuthembeka okuthuthukisiwe, ukumelana okuthuthukisiwe kokuphazamiseka, ukusebenza kahle kwe-spectrum ephezulu, ukwesekwa kokuxhumana kwabasebenzisi abaningi, kanye nokonga amandla, okwenza kube ubuchwepheshe obubalulekile kumanethiwekhi angenantambo anamuhla njenge-Wi-Fi, 4G, kanye ne-5G.
II. Izinzuzo ze-MIMO
I-MIMO (Multiple Input Multiple Output) ubuchwepheshe obusetshenziswa ezinhlelweni zokuxhumana, ikakhulukazi ukuxhumana okungenantambo kanye nomsakazo, okubandakanya ama-antenna amaningi kokubili ku-transmitter kanye ne-receiver. Izinzuzo zezinhlelo ze-MIMO zifaka:
(I-1965)1）Ukuthuthukiswa Kokusetshenziswa Kwedatha: Enye yezinzuzo eziyinhloko ze-MIMO yikhono layo lokukhulisa ukudluliselwa kwedatha. Ngokusebenzisa ama-antenna amaningi kuzo zombili izinhlangothi (ukudlulisa nokwamukela), izinhlelo ze-MIMO zingathumela futhi zamukele ukusakazwa kwedatha okuningi ngasikhathi sinye, ngaleyo ndlela zithuthukise amazinga edatha, okubalulekile ezimweni ezifunwa kakhulu njengokusakaza amavidiyo e-HD noma imidlalo eku-inthanethi.
(I-1965)2（Ukumbozwa Okunwetshiwe: I-MIMO ithuthukisa ukumbozwa kwezinhlelo zokuxhumana ezingenantambo. Ngokusebenzisa ama-antenna amaningi, amasignali angadluliselwa ngezindlela noma ezindleleni ezahlukene, okunciphisa amathuba okufiphala noma ukuphazamiseka kwesignali. Lokhu kuzuzisa kakhulu ezindaweni ezinezithiyo noma ukuphazamiseka.
(I-1965)3）Ukuthembeka Okuthuthukisiwe: Izinhlelo ze-MIMO zithembeke kakhudlwana njengoba zisebenzisa ukuhlukahluka kwendawo ukunciphisa imiphumela yokufiphala nokuphazamiseka. Uma indlela eyodwa noma i-antenna ihlangabezana nokuphazamiseka noma ukufiphala, enye indlela isengadlulisela idatha; lokhu kuphindaphindeka kuqinisa ukuthembeka kwesixhumanisi sokuxhumana.
(I-1965)4）Ukumelana Nokuphazamiseka Okuthuthukisiwe: Izinhlelo ze-MIMO ngokwemvelo zibonisa ukuqina okukhulu ekuphazamisekeni okuvela kwamanye amadivayisi angenantambo kanye nemvelo. Ukusetshenziswa kwama-antenna amaningi kwenza amasu okucubungula amasignali athuthukile njengokuhlunga kwendawo, okungase kuhlunge ukuphazamiseka nomsindo.
(I-1965)5）Ukusebenza Kahle Kwe-Spectrum Okuthuthukisiwe: Izinhlelo ze-MIMO zithola ukusebenza kahle kwe-spectrum okuphezulu, okusho ukuthi zingadlulisela idatha eningi zisebenzisa inani elifanayo le-spectrum etholakalayo. Lokhu kubalulekile uma i-spectrum etholakalayo ilinganiselwe.
(I-1965)6）Usekelo lwabasebenzisi abaningi: I-MIMO ivumela ukwesekwa ngasikhathi sinye kwabasebenzisi abaningi ngokusebenzisa i-spatial multiplexing. Umsebenzisi ngamunye angabelwa umfudlana we-spatial ohlukile, okuvumela abasebenzisi abaningi ukufinyelela inethiwekhi ngaphandle kokuphazamiseka okukhulu.
(I-1965)7）Ukwanda Kokusebenza Kahle Kwamandla: Uma kuqhathaniswa nezinhlelo zendabuko ze-antenna eyodwa, izinhlelo ze-MIMO zingasebenzisa kahle amandla. Ngokwenza ngcono ukusetshenziswa kwama-antenna amaningi, i-MIMO ingadlulisela inani elifanayo ledatha ngokusetshenziswa kwamandla okuphansi.
(I-1965)8）Ukuhambisana Nengqalasizinda Ekhona: Ubuchwepheshe be-MIMO buvame ukuhlanganiswa nengqalasizinda yokuxhumana ekhona, okwenza kube ukukhetha okusebenzayo kokuthuthukisa amanethiwekhi angenantambo ngaphandle kokudinga ukulungiswa okubanzi.
Ngamafuphi, ubuchwepheshe be-MIMO (Multiple Input Multiple Output), obunezinzuzo eziningi ezifana nokuthuthukiswa kwedatha, ukumbozwa, ukuthembeka, ukumelana nokuphazamiseka, ukusebenza kahle kwe-spectrum, ukwesekwa kwabasebenzisi abaningi, kanye nokusebenza kahle kwamandla, sebube ubuchwepheshe obuyisisekelo ezinhlelweni zokuxhumana ezingenantambo zesimanje, okuhlanganisa amanethiwekhi e-Wi-Fi, 4G, kanye ne-5G.
I-Concept Microwave ingumkhiqizi ochwepheshe wezingxenye ze-5G RF eShayina, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/band stop, i-duplexer, i-Power divider kanye ne-directional coupler. Zonke zingenziwa ngokwezifiso ngokuya ngezidingo zakho.izidingo.
