Kev faib tawm ntawm 6GHz Spectrum tiav lawm
Lub Rooj Sab Laj Thoob Ntiaj Teb Txog Xov Tooj Cua Xyoo 2023 (WRC-23) nyuam qhuav xaus rau hauv Dubai, uas tau teeb tsa los ntawm International Telecommunication Union (ITU), lub hom phiaj yog los sib koom tes siv cov spectrum thoob ntiaj teb.
Qhov kev muaj ntawm 6GHz spectrum yog qhov chaw tseem ceeb ntawm kev saib xyuas thoob ntiaj teb.
Lub rooj sib tham tau txiav txim siab: Yuav faib 6.425-7.125GHz band (700MHz bandwidth) rau cov kev pabcuam mobile, tshwj xeeb rau 5G mobile kev sib txuas lus.
6GHz yog dab tsi?
6GHz yog hais txog qhov ntau ntawm cov spectrum txij li 5.925GHz txog 7.125GHz, nrog rau bandwidth txog li 1.2GHz. Yav dhau los, cov spectra zaus nruab nrab mus rau qis rau kev sib txuas lus ntawm tes twb tau siv tshwj xeeb lawm, tsuas yog siv cov spectrum 6GHz xwb tseem tsis meej. Qhov txwv siab tshaj plaws ntawm Sub-6GHz rau 5G yog 6GHz, saum toj no yog mmWave. Nrog rau kev ncua sijhawm ntawm 5G thiab kev lag luam tsis zoo rau mmWave, kev koom ua ke ntawm 6GHz yog qhov tseem ceeb rau theem tom ntej ntawm kev txhim kho 5G.
3GPP twb tau ua tus qauv rau ib nrab sab saud ntawm 6GHz, tshwj xeeb yog 6.425-7.125MHz lossis 700MHz, hauv Tso Tawm 17, tseem hu ua U6G nrog lub npe hu ua n104.
Wi-Fi kuj tau sib tw rau 6GHz. Nrog Wi-Fi 6E, 6GHz tau suav nrog rau hauv tus qauv. Raws li qhia hauv qab no, nrog 6GHz, Wi-Fi bands yuav nthuav dav los ntawm 600MHz hauv 2.4GHz thiab 5GHz mus rau 1.8GHz, thiab 6GHz yuav txhawb nqa txog li 320MHz bandwidth rau ib tus neeg nqa khoom hauv Wi-Fi.
Raws li daim ntawv tshaj tawm los ntawm Wi-Fi Alliance, Wi-Fi tam sim no muab feem ntau lub peev xwm ntawm network, ua rau 6GHz yog yav tom ntej ntawm Wi-Fi. Cov kev thov los ntawm kev sib txuas lus ntawm tes rau 6GHz yog qhov tsis tsim nyog vim tias ntau lub spectrum tseem tsis tau siv.
Nyob rau xyoo tas los no, muaj peb lub tswv yim txog kev muaj 6GHz: Ua ntej, faib nws tag nrho rau Wi-Fi. Qhov thib ob, faib nws tag nrho rau kev sib txuas lus ntawm tes (5G). Qhov thib peb, faib nws sib npaug zos rau ob qho tib si.
Raws li pom tau hauv lub vev xaib Wi-Fi Alliance, cov teb chaws hauv Asmeskas feem ntau tau muab tag nrho 6GHz rau Wi-Fi, thaum cov teb chaws Europe nyiam muab qhov qis dua rau Wi-Fi. Ntawm chav kawm, qhov seem sab saud mus rau 5G.
Qhov kev txiav txim siab ntawm WRC-23 tuaj yeem suav hais tias yog kev lees paub ntawm qhov kev pom zoo uas tau tsim tsa, ua tiav qhov yeej-yeej ntawm 5G thiab Wi-Fi los ntawm kev sib tw thiab kev sib haum xeeb.
Txawm hais tias qhov kev txiav txim siab no yuav tsis cuam tshuam rau kev lag luam hauv Tebchaws Meskas, nws tsis tiv thaiv 6GHz los ntawm kev dhau los ua ib qho band thoob ntiaj teb. Ntxiv mus, qhov zaus qis ntawm cov band no ua rau kev ua tiav kev pabcuam sab nraum zoov zoo ib yam li 3.5GHz tsis nyuaj dhau. 5G yuav coj mus rau hauv nthwv dej thib ob ntawm kev tsim kho siab tshaj plaws.
Raws li GSMA qhov kev kwv yees, qhov kev tsim kho 5G tom ntej no yuav pib rau xyoo 2025, uas yog ib nrab xyoo tom qab ntawm 5G: 5G-A. Peb tos ntsoov rau qhov xav tsis thoob uas 5G-A yuav coj los.
Concept Microwave yog ib lub tuam txhab tsim khoom tshaj lij ntawm 5G/6G RF Cheebtsam hauv Suav teb, suav nrog RF lowpass filter, highpass filter, bandpass filter, notch filter/band stop filter, duplexer, Power divider thiab directional coupler. Tag nrho lawv tuaj yeem hloov kho raws li koj cov kev xav tau.
