Kufunga nezve kutenga foni nyowani yeakakwira-kumhanya 5G? Zviitire zvakanaka: usaite izvi.
Ndiani asingadi kukurumidza Internet uye yakakwirira bandwidth? Munhu wose anoda. Zvakanaka, munhu wese anoda gigabit fiber kuti asvike pamusuwo wavo kana kuhofisi. Pamwe rimwe zuva zvichava saizvozvo. Izvo zvausingazowana ndeye gigabit-per-sekondi kumhanya kwe5G. Kwete ikozvino, kwete mangwana, kwete zvachose.
Parizvino, makambani enharembozha ari kutaura zvinhu zvakawanda mune imwe kushambadzira mushure meimwe zvisiri chokwadi. Asi kunyangwe nezviyero zvavo, 5G ndeyekunyepedzera.
Ngatitange nezita pacharo. Iko hakuna imwechete "5G". Kune marudzi matatu chaiwo ane maitiro akasiyana zvakanyanya.
Chekutanga, 5G ndeye yakaderera-bhendi 20G inopa yakafara kufukidzwa. Imwe shongwe inogona kuvhara mazana emakiromita emakiromita. Haisi dhimoni rekumhanyisa, asi kunyangwe 3+ Mbps kumhanya igehena repamusoro zvakanyanya kupfuura iyo 100 Mbps kumhanya iyo yekumaruwa DSL yakanamatira. Uye mumamiriro ezvinhu akanaka, izvi zvinogona kukupa XNUMX+ Mbps kumhanya.
Ipapo kune yepakati-bhendi 5G, inoshanda mu1GHz kusvika 6GHz renji uye ine inenge hafu yekuvhara ye4G. Iwe unogona kutarisira kuwana kumhanya mu200 Mbps renji. Kana iwe uri muUnited States, haungambosangana nazvo. Inoiswa chete , iyo yakagara nhaka yepakati-frequency 5G ine chiteshi bhendi ye2,5 GHz kubva . Nekudaro, inononoka nekuti yakawanda yayo inogona bandwidth yakatoshandiswa.
Asi chinodiwa nevanhu vazhinji ndeye 1 Gbps kumhanya ine latency pasi pegumi milliseconds. Maererano ne , vangangoita 40% yevashandisi ve iPhone uye 33% yevashandisi veAroid vanofarira zvakanyanya kana zvakanyanya kutenga 5G gadget. Vanoda kukurumidza ikoko, uye vanochida iye zvino. Uye 18% yavo inototi vanonzwisisa musiyano pakati pemhando dze5G network mabhendi.
Kusava nechokwadi. Nekuti dai vainyatsonzwisisa izvi, vangadai vasiri mukumhanya kudaro kutenga 5G smartphone. Iwe unoona, kuti uwane iwo kumhanya, unofanirwa kuve nemamillimeter wave 5G-uye izvo zvinouya nemapako akawanda.
Chekutanga, masaisai akadaro ane hupamhi hwepamusoro hwemamita zana nemakumi mashanu. Kana iwe uchityaira, izvi zvinoreva kuti kusvika paine 150G base zviteshi kwese kwese, unenge uchirasikirwa nezvakawanda zvechiratidzo chako chekumhanya. Muchokwadi, kwemakore mashoma anotevera, kana uchityaira, haugone kushandisa yakakwira-kumhanya 5G.
Uye kunyangwe iwe uri mukati meiyo 5G base chiteshi, chero chinhu - girazi rehwindo, huni, madziro, nezvimwe. - inogona kuvhara chiratidzo chayo chepamusoro-frequency. Saka, transceiver ye5G inogona kunge iri pakona yemugwagwa wako uye haungakwanise kuwana chiratidzo chakanaka.
Zvakaipa sei izvozvo? , Japan inotungamira nhare mbozha sevhisi, iri kushanda pamhando nyowani yegirazi rehwindo kubvumira millimeter-wave 5G kupfuura. Asi hazvigoneke kuti vanhu vazhinji vangade kubvisa zviuru zvemadhora kutsiva windows kuti foni yavo ishande.
Ngatifungei, zvisinei, kuti une foni ye5G uye une chivimbo chekuti unokwanisa kuwana 5G - yakawanda sei kuita kwaungatarisira? Sekureva kweWashington Post tech munyori , unogona kutarisira 5G kuve "yakaoma." Zvinonzwika zvine musoro, unogona kuvimba neizvi:
Edza kumhanya kweAT&T ye32 Mbps ine 5G smartphone uye 34 Mbps ine 4G smartphone. PaT-Mobile, ndakawana 15 Mbps pa5G uye 13 Mbps pane 4G smartphone. Haana kukwanisa kuona Verizon. Asi yake 4G smartphone yakakurumidza kupfuura yake 5G smartphone.
Zvechokwadi, inoshuma kuti avhareji yekumhanya yevashandisi ve5G muUS i33,4 Mbps. Zvirinani pane 4G, asi kwete "Wow!" Izvi zvakanaka! β, izvo vanhu vazhinji vanorota nezvazvo. Izvi zvakanyanya kuipa kupfuura chero imwe nyika inoshandisa 5G kunze kweUK.
Zvakare, iwe unongowana 5G 20% yenguva. Kunze kwekunge iwe uchigara kana kushanda padhuze nemiremita wave transceiver, iwe haungangoona kumhanya kwakavimbiswa kana chero chinhu chiri padyo navo. Kuti uve wakanaka, usatarisire yakakwirira-kumhanya 5G kuti iwanikwe zvakanyanya kusvika 2025. Uye kunyangwe zuva iro rasvika, hazvina chokwadi isu tese tichaona chaiyo gigabit-yechipiri kumhanya.
Nyaya yepakutanga inogona kuwanikwa .
