Ukusukela kwi-802.11n, itekhnoloji ye-MIMO isetyenzisiwe kule protocol kwaye iphucule kakhulu izinga lokuhanjiswa kwamacingo.Ngokukodwa, indlela yokuphucula iteknoloji ephezulu.Ngoku makhe sijonge ngakumbi kwitekhnoloji ye-MIMO.
Ngenkqubela phambili yetekhnoloji yonxibelelwano engenazingcingo, iiprothokholi ezininzi ziyazalwa.Ukuze kuphuculwe izinga lokuhanjiswa kolwazi kunye nokusetyenziswa kwe-bandwidth, iteknoloji ye-antenna eninzi isetyenziswa.Oku kubizwa ngokuba yiMimo.Ukusuka kumbono wefomula kaShannon, itekhnoloji yeMimo inokukhawulezisa isantya apho idatha ithunyelwa khona, nto leyo ephucula umlinganiso wesignali-kwingxolo.
Ngengqiqo ebanzi, i-MIMO ibhekiselele kwimowudi yolwahlulo lwesithuba esiphinda-phindayo esixhasa ukuhanjiswa kweedatha ezininzi ngaxeshanye.Nangona kunjalo, ngamanye amaxesha umbono we-MIMO wahlukile ngenxa yomxholo.Umzekelo, xa sithetha nge-5G, sithetha nge-MIMO enkulu, eligama letekhnoloji yokwenza imiqadi.
I-colum sub sub ichaza umgaqo osisiseko we-MIMO;
Okokuqala, sicinga ukuba kukho imijelo yedatha emibini, i-A kunye ne-B, ehanjiswa ngaxeshanye.Le mijelo emibini yedatha ithunyelwa ngokwahlukeneyo ngee-eriyali ezimbini.Ngeli xesha, imijelo emibini yedatha kufuneka ithumele idatha ukuba idlule kwisistim sesiteshi esingenazingcingo kwaye ifikelele kwii-antenna ezimbini ngaxeshanye ukufumana imiqondiso.Isiphelo sokufumana siqhubela phambili imijelo emibini yedatha yeempawu zedijithali kwaye ibuyisela idatha yemilambo emibini ngokuzimeleyo.Kufuneka kuqatshelwe ukuba ekupheleni kokuthumela, i-RF ekupheleni kweempawu ezimbini zisebenzisa ibhendi yefrikhwensi efanayo xa kulungiswa.Ngokomzekelo, kwimeko ye-5G 100M, iimpawu ezimbini zisebenzisa i-bandwidth ye-100M.Yandisa nje inani leeriyali.
Oku kungasentla yingcaciso yolwazi ye-MIMO Basic Technical Principles eziswe nguI-Shenzhen Haidwiwei Optoelectronic Technology Co., Ltd., umenzi wezixhobo zonxibelelwano zamehlo.Wamkelekile kwiqhagamshelana nathi.
