MIMO (Multiple In, Multiple Out) - kutchulidwa "my-mo" - ndi njira yogwiritsiridwa ntchito kwa mauthenga ambiri a wailesi mu mauthenga osayendetsa opanda waya, omwe amapezeka m'mabutchi amtundu wamakono .
Momwe MIMO amagwirira ntchito
Ma-Wi-Fi omwe amagwiritsa ntchito ma-Wi-Fi amagwiritsira ntchito mapulogalamu amtundu womwewo omwe amatha kuyenda. Chombo cha MIMO chimapangitsa ntchito yapamwamba kupititsa patsogolo ndi kulandira deta kudutsa chilankhulo cha Wi-Fi Mwachindunji, imayambitsa magalimoto ozungulira omwe akuyenda pakati pa makasitomala a Wi-Fi ndi router m'mitsinje yapadera, imatulutsa mitsinje mofanana, ndipo imalola chipangizo cholandirira kubwereranso (kubwereranso) kumbuyo kumalo amodzi.
Kulemba kwa MIMO kungapangitse makina opanga mawindo , mawonekedwe , ndi kudalirika pa chiopsezo chowonjezereka chosokoneza zipangizo zina zopanda waya.
MIMO Technology mu Wi-Fi Networks
Wi-Fi inaphatikizidwa ndi matepi a MIMO monga chiyambi choyamba ndi 802.11n . Kugwiritsira ntchito MIMO kumapangitsa kugwira ntchito ndi kufika kwa mauthenga a Wi-Fi omwe amatha kufanana ndi omwe ali ndi ma-antenna.
Nambala yeniyeni ya nkhono zomwe zimagwiritsidwa ntchito pa MIMO Wi-Fi router zingasinthe. Mabotolo otchuka a MIMO ali ndi ziwalo zitatu kapena zinayi mmalo mwa antenna imodzi yomwe inali yoyenera mu oyendetsa opanda waya.
Zonse makasitomala a Wi-Fi ndi Wi-Fi router ayenera kuthandizira MIMO kuti pakhale mgwirizano pakati pawo kuti agwiritse ntchito chipangizochi ndikuzindikira ubwino wake. Zolembera zopangira mafayilo a router ndi mafoni a kasitomala amatsimikizira ngati ali MIMO angathe. Kupitirira apo, palibe njira yowongoka kuti muwone ngati kugwiritsira ntchito kwanu kugwiritsira ntchito.
SU-MIMO ndi MU-MIMO
Mbadwo woyamba wa mafilimu a MIMO unayambira ndi 802.11n omwe amathandiza MIMO Mmodzi (MU). Poyerekeza ndi MIMO yachikhalidwe komwe maina onse a router ayenera kugwirizanitsidwa kuti aziyankhulana ndi kachipangizo kamodzi kasitomala, SU-MIMO imachititsa kuti pulogalamu iliyonse ya Wi-Fi router ikhale yogawidwa kwa apadera makasitomala apadera.
Mafakitale ambiri a MIMO (MU-MIMO) apangidwa kuti agwiritsidwe ntchito pa ma Wi-Fi 5 GHz 802.11ac Wi-Fi. Ngakhale kuti SU-MIMO ikufunikanso ma routers kuti athetse kasitomala awo (omwe amamvetsera pa nthawi imodzi), ma antennas MU-MIMO amatha kugwirizanitsa mgwirizano ndi osowa ambiri. MU-MIMO imapangitsa kuti kugwirizanitsa ntchito kugwiritsidwe ntchito. Ngakhale pamene router 802.11ac ili ndi chithandizo chofunikira cha ma hardware (osati zitsanzo zonse), zina zoperewera za MU-MIMO zimagwiranso ntchito ::
- imathandizira magalimoto pamsewu umodzi - kuchokera pa router kupita kwa ofuna chithandizo
- imathandizira kokha chiŵerengero chochepa cha makasitomala amodzimodzi amodzimodzi (nthawi zambiri pakati pa awiri ndi anayi) malingana ndi kasinthidwe ka antenna
MIMO mu Cellular Networks
Makanema ambiri muzinthu zamakono angapezeke muzinthu zamakina opanda waya pambali pa Fi. Amapezekanso kwambiri mu maselo (4G ndi zamakono zamakono 5G) mwa mitundu yosiyanasiyana:
- Network MIMO waka MIMO Wothandizira - kuwonetserana bwino pakati pa malo osiyanasiyana
- MIMO yaikulu - pogwiritsa ntchito nambala mazana (mazana) a nyerere pamalo osungira
- Millimeter Wave (mmWave) - pogwiritsira ntchito magulu akuluakulu omwe amawoneka kuti ndi ochuluka kusiyana ndi mabungwe ogwiritsidwa ntchito pa 3G / 4G
