Nrog rau yav tom ntej WRC-23 (2023 World Radiocommunication Conference), kev sib tham ntawm 6GHz kev npaj tau txais cua sov hauv tsev thiab txawv teb chaws.
Tag nrho 6GHz muaj tag nrho bandwidth ntawm 1200MHz (5925-7125MHz).Ntawm qhov teeb meem yog seb puas yuav faib 5G IMTs (raws li daim ntawv tso cai spectrum) lossis Wi-Fi 6E (raws li tsis muaj ntawv tso cai spectrum)
Kev hu los faib 5G daim ntawv tso cai spectrum los ntawm IMT camp raws li 3GPP 5G thev naus laus zis.
Rau IMT 5G, 6GHz yog lwm mid-band spectrum tom qab 3.5GHz (3.3-4.2GHz, 3GPP n77).Piv nrog millimeter yoj band, nruab nrab zaus band muaj zog dua.Piv nrog rau qhov qis qis, qhov nruab nrab band muaj ntau qhov kev pab cuam spectrum.Yog li, nws yog qhov tseem ceeb tshaj plaws kev txhawb nqa rau 5G.
6GHz tuaj yeem siv tau rau mobile broadband (eMBB) thiab, nrog kev pab los ntawm high-tau txais cov kav hlau txais xov thiab beamforming, rau Fixed Wireless Access (wideband).Lub GSMA tsis ntev los no tau mus kom deb li deb tau hu rau tsoomfwv 'tsis ua haujlwm siv 6GHz raws li cov ntawv tso cai spectrum los ua phem rau 5G txoj kev loj hlob thoob ntiaj teb.
Wi-Fi chaw pw hav zoov, raws li IEEE802.11 thev naus laus zis, tso tawm qhov kev xav sib txawv: Wi-Fi yog qhov tseem ceeb rau tsev neeg thiab kev lag luam, tshwj xeeb tshaj yog thaum muaj kev sib kis COVID-19 nyob rau xyoo 2020, thaum Wi-Fi yog cov ntaub ntawv tseem ceeb ua lag luam. .Tam sim no, 2.4GHz thiab 5GHz Wi-Fi bands, uas tsuas muaj ob peb puas MHz, tau dhau los ua neeg coob heev, cuam tshuam rau cov neeg siv kev paub.Wi-Fi xav tau ntau dua spectrum los txhawb qhov kev thov nce ntxiv.6GHz txuas ntxiv ntawm 5GHz band tam sim no yog qhov tseem ceeb rau yav tom ntej Wi-Fi ecosystem.
Kev faib tawm ntawm 6 GHz
Thoob plaws ntiaj teb, ITU Thaj Chaw 2 (Tebchaws Asmeskas, Canada, Latin America) tam sim no tau teeb tsa siv tag nrho 1.2GHz rau Wi-Fi.Qhov tseem ceeb tshaj plaws yog Tebchaws Meskas thiab Canada, uas tso cai rau 4W EIRP ntawm cov qauv tsim tawm AP hauv qee qhov zaus.
Hauv Tebchaws Europe, kev coj tus cwj pwm sib npaug tau txais yuav.Qhov tsawg zaus band (5925-6425MHz) yog qhib rau low-power Wi-Fi (200-250mW) los ntawm European CEPT thiab UK Ofcom, thaum lub siab zaus band (6425-7125MHz) tseem tsis tau txiav txim siab.Hauv Txheej Txheem 1.2 ntawm WRC-23, Tebchaws Europe yuav xav txog kev npaj 6425-7125MHz rau IMT mobile kev sib txuas lus.
Hauv cheeb tsam 3 Asia-Pacific cheeb tsam, Nyiv thiab Kaus Lim Qab Teb tau ib txhij qhib tag nrho cov spectrum rau tsis muaj ntawv tso cai Wi-Fi.Australia thiab New Zealand tau pib tawm tswv yim rau pej xeem, thiab lawv cov phiaj xwm tseem ceeb zoo ib yam li cov teb chaws Europe, uas yog, qhib cov kab hluav taws xob tsawg rau kev siv tsis tau tso cai, thaum lub suab nrov nrov yog tos-thiab-saib.
Txawm hais tias txhua lub teb chaws txoj cai spectrum tau txais txoj cai ntawm "cov txheej txheem thev naus laus zis", uas yog Wi-Fi, 5G NR tsis muaj ntawv tso cai tuaj yeem siv tau, tab sis los ntawm cov cuab yeej siv tam sim no thiab yav dhau los 5GHz kev paub, tsuav yog cov zaus band tsis muaj ntawv tso cai, Wi- Fi tuaj yeem tswj hwm kev lag luam nrog tus nqi qis, kev xa tawm yooj yim thiab ntau tus neeg ua si zoo.
Raws li lub teb chaws nrog lub zog loj tshaj plaws kev sib txuas lus, 6GHz yog ib feem los yog tag nrho qhib rau Wi-Fi 6E nyob rau hauv lub ntiaj teb no.
