Mpikisano wa 5G Technology, Millimeter Wave ndi Sub-6

Nkhondo yaukadaulo wa 5G ndi nkhondo yamagulu pafupipafupi. Pakalipano, dziko limagwiritsa ntchito magulu awiri afupipafupi kuti atumize maukonde a 5G, gulu lafupipafupi pakati pa 30-300GHz limatchedwa millimeter wave; ina imatchedwa Sub-6, yomwe imakhala mu 3GHz-4GHz frequency band.

Kutengera mawonekedwe a mawonekedwe a mafunde a wailesi, kutalika kwake kwakanthawi kochepa komanso mawonekedwe a mtengo wopapatiza wa mafunde a millimeter amathandizira kuwongolera kwazizindikiro, chitetezo chotumizira, ndi liwiro la kufalitsa kuti liwonjezeke, koma mtunda wotumizira umachepetsedwa kwambiri.

Malinga ndi kuyesa kwa 5G kwa Google pamtundu womwewo komanso kuchuluka kwa malo oyambira, ma network a 5G oyendetsedwa ndi mafunde a millimeter amatha kuphimba 11.6% ya anthu pamlingo wa 100Mbps, ndi 3.9% pamlingo wa 1Gbps. 6-band 5G network, 100Mbps rate network ikhoza kuphimba 57.4% ya anthu, ndipo mlingo wa 1Gbps ukhoza kuphimba 21.2% ya anthu.

Zitha kuwoneka kuti kufalikira kwa maukonde a 5G omwe akugwira ntchito pansi pa Sub-6 ndi nthawi zopitilira 5 kuposa mafunde a millimeter. Kuphatikiza apo, kumanga ma millimeter wave base station kumafunikira kuyika pafupifupi 13 miliyoni pamitengo yogwiritsira ntchito, zomwe zingawononge $ 400 biliyoni, kuti zitsimikizire kuti 72% ikupezeka pa 100 Mbps pamphindi imodzi mu gulu la 28GHz ndi pafupifupi 55 pamphindi pa 1Gbps. %. Sub-6 imangofunika kukhazikitsa malo oyambira a 5G pamalo oyambira a 4G, omwe amapulumutsa kwambiri mtengo wotumizira.

Kuchokera pakupanga mpaka pamtengo wogwiritsa ntchito malonda, Sub-6 ndiyabwino kuposa mmWave pakanthawi kochepa.

Koma chifukwa chake n'chakuti zipangizo zamakono zimakhala zambiri, bandwidth yonyamulira imatha kufika ku 400MHz / 800MHz, ndipo mlingo wotumizira opanda zingwe ukhoza kufika kuposa 10Gbps; chachiwiri ndi mtengo wopapatiza wa ma millimeter-wave, njira yabwino, ndi kusinthasintha kwa malo okwera kwambiri; chachitatu ndi zigawo za millimeter-wave Poyerekeza ndi zida za Sub-6GHz, ndizosavuta kuzichepetsa. Chachinai, nthawi ya subcarrier ndi yayikulu, ndipo nthawi imodzi ya SLOT (120KHz) ndi 1/4 ya ma frequency otsika a Sub-6GHz (30KHz), ndipo kuchedwa kwa mawonekedwe a mpweya kumachepetsedwa. M'mapulogalamu achinsinsi achinsinsi, mwayi wa millimeter wave uli pafupi kuphwanya Sub-6.

Pakalipano, mauthenga achinsinsi a galimoto-pansi akugwiritsidwa ntchito ndi mauthenga a millimeter-wave mu makampani oyendetsa sitimayi amatha kukwaniritsa chiwerengero cha 2.5Gbps pansi pa mphamvu yothamanga kwambiri, ndipo kuchedwa kutumizira kumatha kufika ku 0.2ms, yomwe ili ndi mtengo wapatali kwambiri. za kukwezedwa kwachinsinsi pa intaneti.

Pamanetiweki achinsinsi, zochitika monga mayendedwe a njanji ndi kuwunika kwachitetezo cha anthu zitha kupereka kusewera kwathunthu kuukadaulo wamafunde a millimeter kuti mukwaniritse liwiro lenileni la 5G.
