I-MIMO (Multiple In, Multiple Out) - ebizwa ngokuthi "my-mo" - iyindlela yokusetshenziselwa ukuhlanganiswa kwama-antenna amanethiwekhi amaningi ezingxenyeni zenethiwekhi ezingenazintambo, ezivamile kumabhayisikili omfutho wezintambo zasendlini zanamuhla.
Indlela uMIMO esebenza ngayo
Ama-router a-Wi-Fi ase-MIMO asebenzisa izinqubo ezifanayo zenethiwekhi ukuthi iziteshi zendabuko (i-antenna, okungezona i-MIMO). Umzila we-MIMO ufinyelela ukusebenza okuphakeme ngokudlulisa nokuthungatha ngokudlulela idatha kwedatha yokuxhumanisa kwe-Wi-Fi Ngokuqondile, ihlela ithrekhi yenethiwekhi egeleza phakathi kwamakhasimende we-Wi-Fi kanye nomgwaqo ube yimifudlana ngayinye, idlulisela ukusakaza ngokufana, futhi yenza idivayisi yokuthola ukuhlanganisa kabusha (ukubuyisela kabusha) emuva kwimilayezo eyodwa.
Ukukhishwa kwe-MIMO ubuchwepheshe kungandisa ukwanda komthamo wenethiwekhi , ububanzi, nokuthembeka engozini enkulu yokuphazamisa ezinye izinto zokusebenza ezingenazintambo.
I-MIMO Technology ku-Wi-Fi Networks
I-Wi-Fi ifakwe ubuchwepheshe be-MIMO njengendlela evamile eqala ngo- 802.11n . Ukusebenzisa i-MIMO kuthuthukisa ukusebenza nokufinyeleleka kokuxhumana kwenethiwekhi ye-Wi-Fi kuqhathaniswa nalabo abane-antenna routers.
Inombolo ethize ye-antenna esetshenziswa kumzila we-MIMO Wi-Fi ingahluka. Imizila ejwayelekile ye-MIMO iqukethe ama-antenna amathathu noma amane esikhundleni se-antenna elilodwa elilinganiselwe kuma-router angama-wireless amadala.
Kokubili idivayisi yeklayenti ye-Wi-Fi nomzila we-Wi-Fi kufanele usekele i-MIMO ukuze uxhumano phakathi kwabo ukusebenzisa lolu buchwepheshe futhi luqaphele izinzuzo. Amadokhumenti womkhiqizi amamodeli we-router namadivaysi eklayenti acacise ukuthi ngabe yi-MIMO okwazi yini. Ngaphandle kwalokho, ayikho indlela eqondile yokuhlola ukuthi uxhumano lwakho lwenethiwekhi luyisebenzisa yini.
SU-MIMO kanye ne-MU-MIMO
Isizukulwane sokuqala sobuchwepheshe be-MIMO sathunyelwe nge-802.11n esekelwe Umsebenzisi Wodwa Wokusetshenziswa MIMO (SU-MIMO). Uma kuqhathaniswa ne-MIMO yendabuko lapho wonke ama-antenna a-router kufanele ahlanganiswe ukuze axhumane nedivaysi eyodwa yekhasimende, i-SU-MIMO yenza i-antenna ngayinye ye-Wi-Fi router ihlukaniswe ngokwahlukene kumadivaysi amaklayenti ngabanye.
Ubuchwepheshe obuningi be-M-User MIMO (MU-MIMO) budalwe ukuze busetshenziswe kumanethiwekhi ama-5 GHz 802.11ac Wi-Fi. Nakuba i-SU-MIMO idinga ukuthi i-routers ikwazi ukulawula ukuxhumeka kwamakhasimende abo ngezikhathi ezithile (enye iklayenti ngesikhathi), ama-antenna e-MU-MIMO angaphatha ukuxhumeka kwamakhasimende amaningi ngokufana. I-MU-MIMO ithuthukisa ukusebenzisana kokuxhumana okukwazi ukuyisebenzisa. Ngisho noma umshini we-802.11ac unesidingo esiyimfuneko se-hardware (akuwona wonke amamodeli enza), ezinye ukulinganiselwa kwe-MU-MIMO kufaka isicelo ::
- isekela ithrafikhi kuphela kwesinye isiqondiso - ukusuka ku-router kuya kuklayenti
- isekela kuphela inani elilinganiselwe lokuxhumana kwamakhasimende ngesikhathi esisodwa (ngokuvamile phakathi kwamabili nobane) kuye ngokuthi ukulungiswa kwe-antenna yom router
I-MIMO ku-Cellular Networks
Ubuchwepheshe obuningi-ku-Multiple-Out bungatholakala kwezinye izinhlobo zamanethiwekhi angenantambo eceleni kwe-Fi. Kubuye kutholakale ngokwengeziwe kumanethiwekhi omakhalekhukhwini (4G nobuchwepheshe be-5G esizayo) ngezindlela eziningana:
- I-Network MIMO i-Cooperative i-MIMO - ukubonisa okuhlanganisiwe phakathi kweziteshi eziningi eziyisisekelo
- I-Massive MIMO - isebenzisa izinamba ezinkulu (amakhulu) ama-antenna esiteshini sesisekelo
- I-Millimeter Wave (mmWave) - isebenzisa amaqembu aphezulu kakhulu-imvamisa lapho ukutholakala kwe-spectrum kukhulu kunamaqembu alayisensi okusetshenziselwa ukusetshenziswa ku-3G / 4G
