I-MIMO (i-Multiple In, i-Multiple Out) -kwabizwa ngokuthi "yam-mo" - yindlela yokusetyenziswa kwe-antenna ezininzi kwi-intanethi kwi-network network wireless routs .
Indlela iMIMO isebenza ngayo
Ii-routers ze-Wi-Fi ezisekelwe kwi-MIMO zisebenzisa iisetyenziselwano ezifanayo zedololi (ezobugcisa (i-antenna enye, engekho i-MIMO). Umzila we-MIMO ufezekisa ukusebenza ngokuphezulu ngokudlulisa ngokugqithiseleyo nokufumana idatha kwikhonkco le-Wi-Fi Ngokukodwa, luququzelela intengiso yenethiwekhi ehamba phakathi kwamakhasimende akwa-Wi-Fi kunye ne-router kwimifudlana eyahlukeneyo, idlulisela imilambo ngokufanayo, kwaye yenza ukuba isixhobo sokufumana ukuhlaziya kwakhona (ukubuyisela kwakhona) umva kwimilayezo eyodwa.
I-MIMO iteknoloji yokutyikitya inokwandisa umthamo wendlela yomnatha , uhla, kunye nokwethembeka kwengozi eyongeziweyo yokuphazamisana nezinye izixhobo ezingenazintambo.
I-MIMO Technology kwi-Wi-Fi Networks
I-Wi-Fi ifakwe i-MIMO iteknoloji njengomgangatho oqala ngo- 802.11n . Ukusebenzisa i-MIMO kuphucula ukusebenza kunye nokufikeleleka koxhumano lwenethiwekhi ye-Wi-Fi kuthelekiswa nalabo abanee-router-antenna.
Inombolo ethile yeentenna ezisetyenziswa kwi-MIMO Wi-Fi router ingahluka. Iimpawu ze-MIMO eziqhelekileyo ziqulethe ii-antenna ezintathu okanye ezine endaweni ye-antenna enye eyayiqhelekileyo kwii-routers ezingenakucingo ezindala.
Kokubili idivayisi ye-Wi-Fi iklayenti kunye ne-Wi-Fi router kufuneka ixhase i-MIMO ukuze uxhumano phakathi kwabo basebenzise le teknoloji kwaye bafumene iingeniso. Amaxwebhu omenzi womzekelo wombane kunye namajelo omthengi achaza ukuba ngaba yi-MIMO. Ngaphandle koko, akukho ndlela ecacileyo yokujonga ukuba unxibelelwano lwakho lwenethiwekhi luyisebenzisa.
SU-MIMO kunye ne-MU-MIMO
Isizukulwana sokuqala se-MIMO iteknoloji yaziswa ngama-802.11n axhaswa ngumsebenzisi ongabonanga MIMO (SU-MIMO). Ukuthelekiswa ne-MIMO yendabuko apho zonke ii-antennas ze-router kufuneka zilungelelaniswe ukuthetha kunye nesistim esinye somthengi, i-SU-MIMO yenza i-antenna nganye ye-Wi-Fi router ikwabiwe ngokwahlukeneyo kumadivayisi athengiweyo ngabanye.
I-tekhnoloji ye-Multi-User MIMO (MU-MIMO) iye yenzelwa ukusebenzisa kwiinqununu ezingama- GHz 802.11ac ze-Wi-Fi. Nangona i-SU-MIMO ifuna ii-routers ukulawula ukuxhunywa kwabo abaxhasi (umxhasi omnye ngexesha), ii-antenna ze-MU-MIMO zikwazi ukulawula ukunxibelelana nabaxumi abaninzi ngokufanayo. I-MU-MIMO ithuthukisa ukusebenza kwezonxibelelwano ezikwazi ukuzisebenzisa. Nangona i-router engu-802.11ac inexhaswa ye-hardware efunekayo (kungekhona yonke imodeli eyenzayo), ezinye iimingcele ze-MU-MIMO nazo zisebenza ::
- isekela ithrafikhi kuphela kwelinye icala-ukusuka kwi-router ukuya kumxhasi
- isekela kuphela inani elincinci lokuxhunywa kwabaxhamli bexeshanye (ngokuqhelekileyo phakathi kwembini neyezine) kuxhomekeke kwindlela yokulungisa i-antenna
MIMO kwi-Cellular Networks
I-teknoloji-ye-Multiple-Out technology itholakala kwezinye iintlobo zonxibelelwano ezingenazintambo ngaphandle kwe-Fi. Kuye kwandiswe ngokwengeziwe kwiinkonzo zeseli (4G kunye nobuchwepheshe be-5G ezayo) kwiindlela ezininzi:
- I-Network MIMO aka I-MIMO yokusebenzisana - ukubonakaliswa okudibeneyo kwizikhululo ezininzi
- I-MIMO enkulu-esebenzisa amaninzi amakhulu (amakhulu) e-antenna kwisikhululo sesiseko
- I-Millimeter Wave (mmWave) - isebenzisa amaqela aphezulu aphindaphindiweyo apho ukufumaneka kwamagqabantshintshi kunkulu kunamaqela alayisenisiweyo okusetyenziswa kwi-3G / 4G
