Sida aaladaha ugu xidhmaan router-yada wireless-ka marka la isticmaalayo heerarkii hore ( SU-MIMO ama 1x1 MU-MIMO)
Wareeriyeyaasha wirelesska ah ee aan taageero u fidin MU-MIMO(MU-MIMO) waxay isticmaalaan waxa loogu yeero habka SU-MIMO si ay xogta ugu gudbiyaan kanaalka raadiyaha wireless-ka. SU-MIMO waxay u taagan tahay Hal-Isticmale Multiple Input Multiple Output,(Single-User Multiple Input Multiple Output,) waxayna ka dhigan tahay in hal kanaalka wireless uu u diri karo kana heli karo xogta macmiilka shabakadu mar. SU-MIMO waa qayb ka mid ah heerka isku xidhka 802.11n kaas oo la soo gabagabeeyay oo la daabacay Oktoobar 2009(October 2009) . Dhammaan dariiqyada wireless-ka ee taageera nooca ugu dambeeya ee heerka 802.11n waxay isticmaali karaan SU-MIMOhabka loo gudbiyo xogta. Markaad isticmaalayso habkan, router-yadu waxay ku fiican yihiin dirida iyo helitaanka xogta, laakiin kaliya hal jiho, hal macmiil markiiba. Haddii aad lahayd router-ka-wireless-ka oo leh hal anteeno loo isticmaalo soo-helidda iyo dirida xogta, wuxuu isku xiri karaa hal qalab oo shabakad ah markiiba. Aynu ka soo qaadno inaad haysato saddex isticmaale, mid walbana qalabkoodu ku xidhan yahay baahinta WiFi ee router-ku. Router-ku wuxuu u diri karaa oo heli karaa xogta kaliya isticmaalaha ugu horreeya. Marka la sameeyo isticmaalaha koowaad, waxay aadaysaa isticmaalaha labaad ka dibna saddexaad.
Tirada durdurrada xogta isku mar ah ayaa xaddidan tirada ugu yar ee anteenooyinka la isticmaalo. Haddii routerkaaga uu leeyahay afar anteeno, gudaha SU-MIMO , waxaad isku mar yeelan kartaa ilaa afar xog durdurrada. Tusaale ahaan, router-ka bilaa-waayirka ah ee gudbin kara ama ku qaadan kara laba anteeno wuxuu maamuli karaa laba isticmaale isku mar. Router-ka leh afar anteeno wuxuu xamili karaa afar durdur oo kala duwan iyo ilaa afar macmiil isku mar. Tan iyo inta badan WiFishabakadaha waxaad leedahay macaamiil badan oo wireless ah oo ku xiran, mid kastaa wuxuu codsanayaa helitaanka xogtooda, router-ku wuxuu u dhaqmaa sida qoriga mashiinka lagu rakibay meel farxad leh. Waxa ay si degdeg ah uga saartaa qaybo badan oo xog ah oo ay markeeda u dirto qalabyo badan. Qalab kastaa waxa uu sugayaa markiisa si uu u diro oo uu helo xogta, markaa marka qalab cusubi isku xidho, khadka iyo sugitaanka ayaa sii dheeraada. Sidaa darteed, mar kasta oo aaladaha aad ku xirto router-ka wireless-ka ee isticmaalaya SU-MIMO , waa sii weynaada daahitaanka iyo xawaaraha aad ku heleyso aalad kasta.
FIIRO GAAR AH:(NOTE:) Warqadaha farsamada qaarkood, SU-MIMO waxaa loo tixraacaa 1x1 MIMO . Tan maskaxda ku hay markaad aragto 1x1 MIMO oo la isticmaalayo dambe ee maqaalkan.
Waa kuwan waxa MU-MIMO sameeyo marka ay timaado dhanka WiFi:
MU-MIMO, Multi-User MIMO ama Multiple Multiple Input Multiple Output(Multi-User Multiple Input Multiple Output) waa awoodda ay u gudbiyaan dhowr macaamiil isku mar, halkii ay ka ahaan lahaayeen hal kaliya, ama u wareejinta xogta macmiilka shabakad adoo isticmaalaya xog badan oo xog ah hal mar oo sidaas awgeed kordhinta xawaaraha ee wareejinta. Habkan wareejinta ah, router wireless-ku wuxuu "la hadli karaa" in ka badan hal isticmaale markiiba hal kanaal raadiye wireless ah ama hal isticmaale isagoo isticmaalaya xog badan oo qulqulaya isla kanaalka.
Waxaa jira noocyo kala duwan oo ah fulinta MU-MIMO kuwaas oo laga helo jiheeyayaasha iyo qalabka:
- 2x2 MIMO - waxay bixisaa laba durdurrada bannaan ee si toos ah ugu gudbinta iyo helitaanka xogta isla kanaalka ama inta jeer. Hirgelintan, waxaad u baahan tahay laba anteeno oo keliya, waxaadna isku mar ku xidhi kartaa ugu badnaan laba macmiil, mid ka mid ah durdur kasta.
- 3x3 MIMO - waxay bixisaa saddex durdurrada bannaan, waxaadna u baahan tahay saddex anteeno. Waxaad isku mar ku xidhi kartaa ugu badnaan saddex macmiil.
- 4x4 MIMO - waxay bixisaa afar durdurrada bannaan, waxaad u baahan tahay afar anteeno, waxaadna ku xidhi kartaa ugu badnaan afar macmiil.
- 8x8 MIMO - waxa ay bixisaa sideed durdurrada bannaan ee isla kanaalka wireless-ka ama inta jeer ee isku midka ah ilaa ugu badnaan afar macmiil (haa tani waa sax). Hirgelintan, waxaad u baahan tahay siddeed anteeno. 8x8 MIMO wali maaha tignoolajiyada guud.
Sawirka hoose waxaad ku arki kartaa matalaad router ah oo taageero u ah 3x3 MIMO , oo si isku mid ah ula xiriiraya seddex qalab.
Maxaa dhacaya marka aaladahaaga bilaa-waayirka ahi ay sidoo kale taageero u hayaan MU-MIMO ?
