1. Kev txhais ntawm RRU
RRU (Remote Radio Unit) yog hom tshiab ntawm cov khoom siv hauv chaw nres tsheb siv rau kev them nyiaj wireless thiab teeb liab amplification hauv kev sib txuas lus wireless. RRU yog qhov tseem ceeb me me wireless teeb liab txuas, thiab ntau RRUs tuaj yeem txuas ua ke los tsim tib lub teeb liab wireless faib. Piv nrog rau cov khoom siv hauv paus chaw nres tsheb, RRU nyob hauv thaj chaw me me thiab muaj lub zog qis dua. Yog li ntawd, RRU tuaj yeem muab tso rau hauv qhov chaw yooj yim dua thiab me dua rau kev teeb tsa, xws li xov tooj ncej, ru tsev, thiab lwm yam.
2. Daim ntawv thov scenarios ntawm RRU
rru yog
RRU feem ntau yog siv rau hauv kev tsim kho thiab kev saib xyuas ntawm cov chaw nres tsheb hauv kev sib txuas lus mobile. Tam sim no, RRU feem ntau yog siv hauv cov hauv qab no:
1. macro chaw nres tsheb kev tsim kho: RRU tuaj yeem siv rau macro chaw nres tsheb kev tsim kho hauv cov xov tooj ntawm tes, nrog rau thaj chaw dav dav, uas tuaj yeem ua tau raws li qhov loj ntawm kev sib txuas lus wireless.
2. Kev faib tawm sab hauv tsev: RRU tuaj yeem siv ua ke nrog DAS (Distributed Antenna System) los muab kev pabcuam zoo dua hauv kev tsim kho hauv tsev.
3. Kev hloov zuj zus ntawm kev sib txuas lus ntawm cov neeg siv xov tooj: RRU ua lub luag haujlwm tseem ceeb hauv cov txheej txheem kev hloov pauv ntawm cov neeg siv xov tooj thiab tuaj yeem txhim kho tus nqi thiab kev ntseeg siab ntawm kev xa cov ntaub ntawv.
3. Qhov zoo thiab qhov tsis zoo ntawm RRU
Raws li hom tshiab ntawm cov khoom siv hauv paus, RRU muaj qhov zoo hauv qab no:
1. Cov hneev taw me me: Cov cuab yeej siv hauv paus hauv paus feem ntau yuav tsum muaj cov hneev taw loj dua, tab sis RRUs me me thiab hnav, thiab tuaj yeem siv tau yooj yim dua, yog li ua tiav qhov kev faib tawm ntawm cov chaw nres tsheb tsim nyog.
2. Tsawg lub zog: Cov khoom siv hauv paus chaw nres tsheb muaj lub zog siab thiab yuav tsum tau siv lub zog siab. Hauv qhov sib piv, RRU tuaj yeem sib txuas lus hauv Is Taws Nem thiab txo lub zog ntawm modem, thiaj li ua tiav cov txiaj ntsig txuag hluav taws xob.
3. Kev dav dav: Vim tias RRU tuaj yeem sib txuas lus nrog lwm cov khoom siv hauv chaw nres tsheb, lub wireless network loj tuaj yeem tsim tau uas tuaj yeem npog thaj tsam dav.
Txawm li cas los xij, RRU kuj muaj qhov tsis zoo hauv qab no:
1. Cov teeb liab loj poob: Txawm hais tias RRU tuaj yeem muab qhov dav dav ntawm cov teeb liab wireless, vim nws qhov me me, lub teeb liab lub zog feem ntau tsis muaj zog dua li cov khoom siv hauv paus chaw nres tsheb, yog li muaj qee qhov teeb meem poob.
2. Kev ruaj ntseg tsis zoo: Lub network txuas nrog RRU tuaj yeem ntsib qhov kev tawm tsam tsis txaus ntseeg, uas ua rau muaj kev pheej hmoo ntawm kev nyab xeeb.
4. Cov ntsiab lus
Raws li ib feem tseem ceeb ntawm kev sib txuas lus mobile tiam tom ntej, RRU muaj ntau yam zoo xws li hneev taw me me, tsis muaj zog, thiab kev siv dav dav, thiab tuaj yeem ua tau raws li qhov dav dav thiab cov teeb liab amplification xav tau ntawm kev sib txuas lus wireless. Nrog kev txhim kho txuas ntxiv ntawm thev naus laus zis, RRU tseem yuav txuas ntxiv txhim kho thiab txhim kho, txhaj ntau qhov tseem ceeb rau hauv txoj kev loj hlob ntawm kev lag luam kev sib txuas lus mobile.
