5G ndi nthabwala yoyipa pakadali pano

Mukuganiza zogula foni yatsopano ya 5G yothamanga kwambiri? Dzichitireni zabwino: musachite izi.

Ndani safuna intaneti yachangu komanso bandwidth yayikulu? Aliyense amafuna. Moyenera, aliyense amafuna kuti gigabit fiber ifike pakhomo pawo kapena kuofesi. Mwina tsiku lina zidzakhala choncho. Zomwe simungapeze ndi kuthamanga kwa gigabit-per-sekondi iliyonse ya 5G. Osati tsopano, osati mawa, osati konse.

Pakadali pano, makampani opanga ma telecom akunena zinthu zambiri pazotsatsa zingapo zomwe sizowona. Koma ngakhale ndi miyezo yawo, 5G ndi yabodza.

Tiyeni tiyambe ndi dzina lenilenilo. Palibe "5G" imodzi. Pali mitundu itatu yokhala ndi mawonekedwe osiyana kwambiri.

Choyamba, 5G ndi 20G yotsika kwambiri yomwe imapereka chidziwitso chachikulu. Chinsanja chimodzi chimatha kunyamula ma kilomita mazanamazana. Sichiwanda chothamanga, koma ngakhale kuthamanga kwa 3+ Mbps ndi gehena yabwino kwambiri kuposa kuthamanga kwa 100 Mbps komwe DSL yakumidzi imakhala nayo. Ndipo muzochitika zabwino, izi zitha kukupatsani liwiro la XNUMX+ Mbps.

Ndiye pali mid-band 5G, yomwe imagwira ntchito mu 1GHz mpaka 6GHz ndipo ili ndi pafupifupi theka la 4G. Mutha kuyembekezera kupeza liwiro mumtundu wa 200 Mbps. Ngati muli ku United States, mwina simudzakumana nazo. Amatumizidwa kokha T-Mobile, yomwe idalandira cholowa chapakati pa pafupipafupi 5G yokhala ndi kanjira ya 2,5 GHz kuchokera Sprint. Komabe, ndipang'onopang'ono chifukwa zambiri zomwe zingagwiritsidwe ntchito zimagwiritsidwa ntchito kale.

Koma zomwe anthu ambiri amafuna ndi liwiro la 1 Gbps ndi latency pansi pa 10 milliseconds. Malinga ndi maphunziro atsopano a NPD, pafupifupi 40% ya ogwiritsa ntchito iPhone ndi 33% ya ogwiritsa ntchito Android amakonda kwambiri kugula zida za 5G. Iwo akufuna liwiro limenelo, ndipo akulifuna ilo tsopano. Ndipo 18% ya iwo amati amamvetsetsa kusiyana pakati pa mitundu yamagulu amtundu wa 5G.

Zokayikitsa. Chifukwa akadamvetsetsadi izi, sakadathamangira kugula foni yam'manja ya 5G. Mukuwona, kuti mutenge liwiro lawo, muyenera kukhala ndi millimeter wave 5G - ndipo izi zimabwera ndi chenjezo zambiri.

Choyamba, mafunde oterewa amakhala ndi kutalika kwa 150 metres. Ngati mukuyendetsa, izi zikutanthauza kuti mpaka pakhale malo oyambira a 5G paliponse, mukhala mukutaya siginecha yanu yothamanga kwambiri. M'malo mwake, zaka zingapo zikubwerazi, ngati mukuyendetsa, simungathe kugwiritsa ntchito 5G yothamanga kwambiri.

Ndipo ngakhale mutakhala pamalo oyambira a 5G, chilichonse - galasi lazenera, matabwa, khoma, ndi zina. - ikhoza kuletsa chizindikiro chake chafupipafupi. Chifukwa chake, transceiver ya 5G ikhoza kukhala pakona ya msewu wanu ndipo simungathe kupeza chizindikiro chabwino.

Ndi zoipa bwanji zimenezo? NTT Chidziwitso, Wotsogola wotsogola ku Japan wopereka mafoni am'manja, akugwira ntchito yopangira mtundu watsopano wagalasi lazenera kuti alole ma millimeter-wave 5G kudutsa. Koma ndizokayikitsa kuti anthu ambiri angafune kuwononga madola masauzande angapo kuti asinthe mawindo kuti foni yawo igwire ntchito.

Tiyerekeze, komabe, kuti muli ndi foni ya 5G ndipo muli ndi chidaliro kuti mutha kupeza 5G - mungayembekezere kugwira ntchito kotani? Malinga ndi wolemba nkhani waukadaulo wa Washington Post Jeffrey A. Fowler, mutha kuyembekezera kuti 5G ikhale "yopusa." Zikumveka zomveka, mutha kukhulupirira izi:

"Yesani kuthamanga kwa AT&T kwa 32 Mbps ndi foni yam'manja ya 5G ndi 34 Mbps yokhala ndi foni yam'manja ya 4G. Pa T-Mobile, ndili ndi 15 Mbps pa 5G ndi 13 Mbps pa foni yamakono ya 4G. Sanathe kutsimikizira Verizon. Koma foni yake yamakono ya 4G inali yofulumira kuposa foni yake ya 5G.

Inde OpenSignal akuti liwiro lapakati la ogwiritsa ntchito 5G ku US ndi 33,4 Mbps. Zabwino kuposa 4G, koma osati "Wow!" Izi ndizabwino! ”, zomwe anthu ambiri amazilota. Izi ndizoyipa kwambiri kuposa dziko lina lililonse lomwe likugwiritsa ntchito 5G kupatula UK.

Komanso, mumangopeza 5G 20% ya nthawiyo. Pokhapokha mutakhala kapena kugwira ntchito pafupi ndi ma millimeter wave transceiver, simudzawona liwiro lolonjezedwa kapena chilichonse pafupi nawo. Kunena chilungamo, musayembekezere kuti 5G yothamanga kwambiri ipezeka ponseponse mpaka 2025. Ndipo ngakhale tsiku limenelo likadzafika, ndizokayikitsa kuti tonse tidzawona kuthamanga kwenikweni kwa gigabit-sekondi.

Nkhani yoyambirira ingapezeke apa.
