MIMO tekinoroji ipfungwa yakakosha mune isina waya yekutaurirana tekinoroji.Inogona kuvandudza zvakanyanya kugona uye kuvimbika kwematanho asina waya uye kuvandudza kunaka kwekutaurirana kusina waya.MIMO tekinoroji yakashandiswa zvakanyanya mune dzakasiyana siyanawireless communication systemsuye yave chikamu chakakosha chemazuva ano mawaya ekukurukurirana tekinoroji.
●Tekinoroji yeMIMO inoshanda sei?
MIMO tekinoroji inoshandisa akawanda kutumira uye kugamuchira antenna kutumira uye kugamuchira data.Iyo data yakafambiswa ichakamurwa kuita akawanda masaini-masaini uye anotumirwa kuburikidza neakawanda anotumira antenna zvichiteerana.Maantenna akawanda anogashira anotora aya madiki-masaini uye oabatanidza iwo muiyo yekutanga data.Iyi tekinoroji inobvumira akawanda data hova kuti ifambiswe pane imwechete frequency bhendi, nekudaro ichiwedzera spectral kunyatsoita uye system kugona.
●Zvakanakira zveMIMO tekinoroji
Kana chiratidzo cheredhiyo chinoratidzwa, makopi akawanda echiratidzo anogadzirwa, imwe neimwe iri rwizi rwenzvimbo.Tekinoroji yeMIMO inobvumira maantenna akawanda kufambisa uye kugashira hova dzakawanda dzepamhepo panguva imwe chete, uye inokwanisa kusiyanisa masaini anotumirwa kana kubva kwakasiyana mativi enzvimbo.Iko kushandiswa kweMIMO tekinoroji kunoita kuti nzvimbo ive sosi inogona kushandiswa kuvandudza mashandiro uye kuwedzera kufukidzwa kweasina waya masisitimu.
1.Kuwedzera mukana wechiteshi
Kushandisa MIMO masisitimu inzira inoshanda yekuvandudza spectral kunyatsoita.Multiple spatial hova dzinogona kutumirwa uye kugashirwa panguva imwe chete pakati peMIMO yekuwana nzvimbo uye MIMO mutengi.Iyo chiteshi simba inogona kuwedzera mutsetse sezvo huwandu hweantenna hunowedzera.Naizvozvo, iyo MIMO chiteshi inogona kushandiswa kuwedzera zvakanyanya waya isina waya chiteshi.Pasina kuwedzera bandwidth uye antenna yekufambisa simba, kushandiswa kwe spectrum kunogona kuwedzerwa exponentially.
2.Improve channel kuvimbika
Uchishandisa iyo spatial multiplexing kuwana uye kusiyanisa kwepakati kuwana kwakapihwa neiyo MIMO chiteshi, akawanda antenna anogona kushandiswa kudzvanya chiteshi kupera.Iko kushandiswa kweakawanda-antenna masisitimu inobvumira inofanana dhata nzizi kuti ifambiswe panguva imwe chete, iyo inogona zvakanyanya kukunda chiteshi kupera uye kuderedza chiyero chekukanganisa.
3.Improve Anti-kupindira Performance
Tekinoroji yeMIMO inogona kuderedza kupindira pakati pevashandisi uye kuvandudza mashandiro e-anti-interference yetiweki kuburikidza nemaantenna akawanda uye tekinoroji yekuparadzanisa nzvimbo.
4.Improve Coverage
MIMO tekinoroji inogona kuvandudza kuvharika kweiyo sisitimu nekuti tekinoroji yeMIMO inogona kushandisa akawanda antenna kufambisa data, nekudaro ichivandudza chinhambwe chekufambisa kwemasaini uye kugona kupinda.Munguva yekutapurirana, kana mamwe ma antenna akabatwa nekuvharika kana kudzikisira, mamwe antenna anogona kuramba achiendesa data, nekudaro achivandudza chiratidzo chekuvhara.
5. Adapt kune Various Channel Environments
MIMO tekinoroji inogona kuchinjika kune akasiyana siyana chiteshi nharaunda.Izvi zvinodaro nekuti tekinoroji yeMIMO inogona kushandisa akawanda antenna ekufambisa data, nekudaro kuchinjira kune shanduko munzvimbo dzakasiyana dzechiteshi.Munguva yekutapurirana, nzvimbo dzakasiyana dzechiteshi dzinogona kuve nemhedzisiro dzakasiyana pakufambiswa kwechiratidzo, senge multipath effect, Doppler effect, etc. MIMO tekinoroji inogona kuchinjika kune akasiyana chiteshi nharaunda nekushandisa akawanda antenna.
Mhedziso
Tekinoroji yeMIMO yakashandiswa zvakanyanya mumasevhisi akasiyana siyana ekutaurirana, anosanganisira WLAN, LTE, 5G, nezvimwewo.kutaurirana chigadzirwakuvandudza nekugadzira, IWAVE R&D timu inotarisa kugadzira mini yakachengeteka isina waya data link yemwenje, diki uye diki mhepo isina kurongwa mapuratifomu uyemapuratifomu asina vanhu.
IWAVE's self-developed MESH wireless network zvigadzirwa zvinotora MIMO tekinoroji ine zvakanakira kureba kutapurirana chinhambwe, yakaderera latency, yakagadzikana kufambisa uye kutsigirwa kwenzvimbo dzakaoma.Inoshandiswa zvakanyanya munzvimbo dzine vanhu vazhinji, vashoma veruzhinji network base zviteshi, uye isina kugadzikana network.Iro dhizaini yakakosha yekununura munzvimbo dzenjodzi dzakadai sekuvhiringwa kwemigwagwa kamwe kamwe, kubviswa kweInternet, uye kudzimwa kwemagetsi.
