I-5G yitekhnoloji yonxibelelwano yesizukulwana sesihlanu, ebonakaliswa ubukhulu becala nge-millimeter wavelength, i-ultra wideband, i-ultra-high speed, kunye ne-ultra-low latency.I-1G iphumelele unxibelelwano lwezwi le-analog, kwaye umzalwana omkhulu akanalo isikrini kwaye unokwenza iifowuni kuphela;I-2G iphumelele i-digitization yokunxibelelana kwezwi, kwaye umatshini osebenzayo unesikrini esincinci esinokuthumela imiyalezo yombhalo;I-3G iphumelele unxibelelwano lwe-multimedia ngaphaya kwelizwi kunye nemifanekiso, okwenza isikrini sibe sikhulu ukujonga imifanekiso;I-4G ifikelele kwi-intanethi ye-intanethi ye-intanethi, kwaye ii-smartphones ezinkulu zesikrini zinokubukela iividiyo ezimfutshane, kodwa umqondiso ulungile kwimimandla yasezidolophini kunye nehlwempu kwiindawo zasemaphandleni.I-1G ~ 4G igxininise kunxibelelwano olulula kunye nolusebenzayo phakathi kwabantu, ngelixa i-5G iya kwenza unxibelelwano lwezinto zonke nangaliphi na ixesha, naphi na, ivumela abantu ukuba babe nobuganga bokulindela inxaxheba ehambelanayo kunye nazo zonke izinto eziseMhlabeni ngokusasaza okuphilayo ngaphandle kokwahlukana kwexesha.
Ukufika kwexesha le-5G kunye nokuqaliswa kobuchwephesha be-Massive MIMO kuye kwakhokelela ngokuthe ngqo kwiindlela ezintathu zokuphuhliswa kwee-antenna zesikhululo se-5G:
1) Ukuphuhliswa kwe-eriyali esebenzayo ukuya kwii-eriyali ezisebenzayo;
2) IFiber optic replacement feeder;
3) I-RRH (intloko ye-radio frequency remote) kunye ne-eriyali idityaniswe ngokuyinxenye.
Ngokuziphendukela okuqhubekayo kothungelwano lonxibelelwano olusingise kwi-5G, ii-eriyali zokubonisa (i-multi-antenna space division multiplexing), i-eriyali ezininzi ze-beam (uxinaniso lwenethiwekhi), kunye nee-eriyali zamabhandi amaninzi (ukwandiswa kwe-spectrum) ziya kuba zezona ntlobo ziphambili zophuhliso lwe-eriyali yesikhululo kwixesha elizayo.
Ngokufika kweenethiwekhi ze-5G, iimfuno zabaqhubi abakhulu beenethiwekhi zeselula zihlala zitshintsha.Ukuze kuphunyezwe ukhuseleko olupheleleyo lwenethiwekhi, zininzi nangakumbi iintlobo ze-eriyali zothungelwano lwesiseko zisetyenziswa ngokubanzi kwicandelo lonxibelelwano oluphathwayo.Kwii-antenna ezine frequency, ukuze ufezekise ulawulo lwe-engile yokuthambeka kwe-elektroniki ukuya ezantsi, okwangoku kukho iintlobo ezintathu eziphambili zezixhobo zolawulo lohlengahlengiso lombane, kubandakanya indibaniselwano yabalawuli ababini abalungelelanisiweyo bombane abadityanisiweyo, isilawuli sohlengahlengiso lombane ezimbini. kunye ne-transmission switching mechanism, kunye nezilawuli zohlengahlengiso zombane ezine ezakhelwe ngaphakathi.Ingabonwa ukuba kungakhathaliseki ukuba yiyiphi idivaysi esetyenzisiweyo, ayinakuhlukaniswa kwisicelo se-antenna motors.
Esona sakhiwo siphambili sesiseko sombane we-antenna motor ngumatshini wokunciphisa odibeneyo owenziwe yimoto yokuhambisa kunye nebhokisi yegiya yokunciphisa, enomsebenzi wohlengahlengiso lokunciphisa;Imoto yothumelo ibonelela ngesantya sokuphuma kunye nesantya esisezantsi setorque, kwaye ibhokisi yegiya iqhagamshelwe kwimoto yokuhambisa ukunciphisa isantya sokuphuma kwemoto yokuhambisa ngelixa isonyusa itorque, ukufikelela kwisiphumo esifanelekileyo sothumelo;Isiseko sombane we-antenna motor gearbox sihlala sithatha iparameters yemoto yegiya yegiya, amandla, kunye nokusebenza ukuhlangabezana ngcono nezinto zokusingqongileyo ezifana nokusingqongileyo, imozulu, umahluko wobushushu, kunye nokufezekisa isiphumo esifanelekileyo sothumelo kunye neemfuno zobomi benkonzo.
