CPE (cov cuab yeej siv cov neeg siv khoom) yog cov cuab yeej siv network uas hloov kho lub davhlau ya nyob twg (Wi-Fired Broadband)
Tsis zoo li cov routers ib txwm, CPE tuaj yeem txuas rau cov tes hauj lwm txawb los ntawm kev ntxig daim npav SIM tsis muaj kev vam meej ntawm cov kab ruaj khov. Nws muaj zog kav hlau txais xov tau txais, kev pab cuam ntau dua, thiab ntau dua bandwidth dua li xov tooj txawb hotspots.
Cov neeg cob qhia CPE tshwj xeeb yog tsim nyog rau cov chaw nrog cov kev pab fiber ntau, kev ua haujlwm ib ntus (piv txwv li cov kev ua haujlwm hauv tsheb / chaw tsheb.
Dab tsi yog qhov sib txawv ntawm aCPE Routerthiab ib qho dog digWiFi router, a Txawb xov tooj Hotspot, thiab aPortable Wi-Fi?
Qhov sib txawv ntawm CPE cov routers thiab cov rouch zoo tib yam yog lawv txhawb nqa SIM daim npav kev ua tau zoo thiab ruaj khov, thiab qhov sib txawv los ntawm qhov loj me thiab muaj peev xwm nqa muaj peev xwm.

Dab tsi yog qhov kev ua tau zoo sib txawv ntawm 5G CPE thiab 4G CPE hauv kev siv tiag?
Theoretical ncov ntawm5G CPEtuaj yeem ncav cuag 10GBs, thiab ntsuas kev ntsuas nrawm yog feem ntau 200-500mbps (thiab qee qhov xwm txheej muaj peev xwm ncav cuag 800mbps, thiab upload ceev yog li 50-100mbps. Nws txhawb nqa 32-256 cov cuab yeej sib txuas (Wi-Fi 6 Technology 5 Gand High bandwidth), thiab pob ntawv poob tsawg dua los yog sib npaug rau 0.3% thaum 10 pab kiag li lawm.
Haum rau 4K yees duab streaming, huab ua si, thiab cov ntaub ntawv loj rub tawm.
Xaus-rau-kawg latency tuaj yeem qis li 1-3ms (suav nrog huab cua chaw nres nkoj kis thiab NAT Kev txhais lus), thiab ntsuas kev ua si / nyob streaming latency yog 15-30ms.
Theoretical ncov ntawm4G CPEyog li 150 cmbps, tab sis qhov kev txo qis yog qhov tseem ceeb vim yog lub hauv paus chaw nres tsheb ceev txo thiab congestion. Cov ntaub ntawv ntsuas feem ntau tsuas yog 20-50Mbps (txog 2.5-6.25mb / s), thiab nws yuav qis dua 20mbps hauv cov cim nyob deb nroog lossis thaj chaw uas tsis muaj zog ntawm cov cim.
Nws tsuas yog txhawb nqa du playback ntawm 720p video, thiab 1080p yuav ua siab ntev, ua rau cov kev paub tsis zoo thaum ntau yam khoom siv yog tib yam nkaus. Txuas ntxiv rau ntau dua 5 pab kiag li yog pom kev lag luam, thiab lub latency ntawm ntau dua 7 cov khoom siv tsis tuaj yeem ua tau raws li cov tsev ntse lossis chaw haujlwm me.
Lub latency feem ntau yog 30-70s, thiab kev ua si lossis cov rooj sib tham ntawm cov nkauj yog xav tau lag thiab kaw suab thiab video tawm-ntawm-ntawm-sy-of-of-of-of sy-of-of-of-of sync.
