I-5G iwubuchwepheshe bokuxhumana besizukulwane sesihlanu, ikakhulukazi ebonakala nge-millimeter wavelength, i-ultra wideband, isivinini esiphezulu, kanye ne-ultra-low latency.I-1G izuze ukuxhumana kwezwi le-analog, futhi umfowethu omdala akanaso isikrini futhi angakwazi ukushaya izingcingo kuphela;I-2G ifinyelele idijithali yokuxhumana ngezwi, futhi umshini osebenzayo unesikrini esincane esingathumela imilayezo yombhalo;I-3G izuze ukuxhumana kwe-multimedia ngale kwezwi nezithombe, okwenza isikrini sibe sikhulu ukuze ubuke izithombe;I-4G izuze ukufinyelela kwe-inthanethi okushesha kakhulu kwendawo, futhi ama-smartphones esikrini esikhulu angabuka amavidiyo amafushane, kodwa isignali yinhle ezindaweni zasemadolobheni futhi impofu ezindaweni zasemaphandleni.I-1G~4G igxile ekuxhumaneni okulula kakhulu nokusebenza kahle phakathi kwabantu, kuyilapho i-5G izonika amandla ukuxhumanisa kwazo zonke izinto noma nini, noma kuphi, ivumela abantu ukuba balokothe balindele ukuhlanganyela okuvumelanayo nazo zonke izinto eziseMhlabeni ngokusakaza bukhoma ngaphandle komehluko wesikhathi.
Ukufika kwenkathi ye-5G kanye nokwethulwa kobuchwepheshe be-Massive MIMO kuholele ngokuqondile emikhubeni emithathu yokuthuthukiswa kwama-antenna esiteshi se-5G:
1) Ukuthuthukiswa kwezimpondo ze-passive maqondana nezimpondo ezisebenzayo;
2) Fibre optic esikhundleni feeder;
3) I-RRH (ikhanda elikude lefrikhwensi yomsakazo) kanye nothi kuhlanganiswe kancane.
Ngokuvela okuqhubekayo kwamanethiwekhi okuxhumana abheke ku-5G, ama-antenna abonisa (i-multi-antenna space division multiplexing), izimpondo eziningi ze-beam (ukuminyana kwenethiwekhi), nama-multi band antenna (ukunwetshwa kwe-spectrum) kuzoba izinhlobo eziyinhloko zokuthuthukiswa kwe-antenna yesiteshi esikhathini esizayo.
Ngokufika kwamanethiwekhi e-5G, izimfuno zabaqhubi abakhulu bamanethiwekhi eselula zishintsha njalo.Ukuze kuzuzwe ukusabalala kwenethiwekhi okugcwele, izinhlobo eziningi kakhulu zama-antenna okushuna iziteshi zisetshenziswa kabanzi emkhakheni wezokuxhumana omakhalekhukhwini.Kuma-antenna amane, ukuze kuzuzwe ukulawula i-engeli yayo ye-elekthronikhi ebheke phansi etshekile, okwamanje kunezinhlobo ezintathu eziphambili zamadivayisi okulawula ukulungisa ugesi, okuhlanganisa inhlanganisela yezilawuli ezimbili zokulungisa zikagesi ezakhelwe ngaphakathi ezimbili, isilawuli sokulungisa ugesi esikabili. enomshini wokushintsha ugesi, kanye nezilawuli ezine zokulungisa ugesi ezakhelwe ngaphakathi.Kungabonakala ukuthi kungakhathaliseki ukuthi iyiphi idivayisi esetshenziswayo, ayikwazi ukuhlukaniswa nokusetshenziswa kwama-antenna motors.
Isakhiwo esikhulu se-base station station tuning antenna motor ingumshini odidiyelwe we-motor reducer owenziwe ngemoto yokudlulisa kanye nebhokisi le-gearbox lokunciphisa, elinomsebenzi wokulungisa ukusheshisa;I-motor transmission ihlinzeka ngesivinini esiphumayo kanye nesivinini esiphansi se-torque, futhi i-gearbox ixhunywe ku-motor yokudlulisela ukunciphisa isivinini sokuphuma kwemoto yokudlulisela ngenkathi ikhulisa i-torque, ifinyelela umphumela ofanele wokudlulisela;I-base station station tuning antenna motor gearbox ngokuvamile isebenzisa amapharamitha obuchwepheshe enziwe ngokwezifiso, amandla, nokusebenza ukuze kuhlangatshezwane kangcono nezici zemvelo ezifana nemvelo, isimo sezulu, umehluko wezinga lokushisa, kanye nokuzuza umphumela ofanele wokudlulisela kanye nezidingo zempilo yesevisi.
