Hondo ye5G tekinoroji nzira ihondo yema frequency band. Parizvino, nyika inoshandisa mabhendi maviri akasiyana-siyana kuendesa 5G network, iyo frequency band pakati pe30-300GHz inonzi millimeter wave; imwe yacho inonzi Sub-6, iyo yakanangidzirwa mu3GHz-4GHz frequency band.
Zvichienderana nehunhu hwemasaisai eredhiyo, hupfupi hwewavelength uye nhete yedanda hunhu hwemamirimita masaisai inogonesa kugadziriswa kwechiratidzo, kuchengetedzeka kwekutapurirana, uye kumhanya kwekutapurirana kukwidziridzwa, asi chinhambwe chekufambisa chinodzikiswa zvakanyanya.
Maererano neGoogle's 5G coverage test yemhando imwe chete uye nhamba imwechete yezviteshi zvepasi, network ye5G yakashandiswa nemamilimita mafungu inogona kuvhara 11.6% yevanhu pamwero we100Mbps, uye 3.9% pamwero we1Gbps. 6-band 5G network, 100Mbps rate network inogona kuvhara 57.4% yevanhu, uye 1Gbps rate inogona kuvhara 21.2% yevanhu.
Zvinogona kuoneka kuti kufukidzwa kwe5G network inoshanda pasi pe Sub-6 inodarika ka5 iyo yemamita mafungu. Pamusoro pezvo, kuvakwa kwemamillimeter wave base station kunoda kuisirwa miriyoni gumi nenhatu pamapango ekushandisa, izvo zvinodhura madhora mazana mana emadhora, kuitira kuti ive nechokwadi chekuvharirwa pa100 Mbps pasekondi makumi mashanu neshanu pasekondi gumi neshanu pa1Gbps. %. Iyo Sub-6 inongoda kuisa 5G base station pane yekutanga 4G base station, iyo inochengetedza zvakanyanya mutengo wekutumira.
Kubva pakuvhara kusvika kumutengo mukushandiswa kwekutengesa, Sub-6 yakakwirira kune mmWave munguva pfupi.
Asi chikonzero ndechekuti zviwanikwa zve spectrum zvakawandisa, mutakuri webhanwidth anogona kusvika 400MHz / 800MHz, uye iyo isina waya yekutumira chiyero inogona kusvika kupfuura 10Gbps; chechipiri idanda rakatetepa remamilimita-wave, gwara rakanaka, uye kugadzirisa kwenzvimbo kwakanyanyisa; yechitatu ndiyo millimeter-wave zvikamu Zvichienzaniswa ne Sub-6GHz midziyo, zviri nyore kuita miniaturize. Chechina, subcarrier interval yakakura, uye imwechete SLOT nguva (120KHz) ndeye 1/4 yeyakaderera frequency Sub-6GHz (30KHz), uye kunonoka kwemhepo kunononoka. Mune yakavanzika network application, iyo mukana wemillimeter wave inenge ichipwanya Sub-6.
Parizvino, iyo yemotokari-yepasi yekukurukurirana yakavanzika network inoshandiswa nemirimita-wave kutaurirana mune njanji yekufambisa njanji inogona kuwana chiyero chekufambisa che2.5Gbps pasi pekumhanya-mhanya, uye kunonoka kwekufambisa kunogona kusvika 0.2ms, iyo ine kukosha kwakanyanya. ye private network promotion.
Kune akavanzika network, zvimiro zvakaita senjanji yekufambisa uye yeruzhinji chengetedzo yekutarisa inogona kupa yakazara kutamba kune tekinoroji mabhenefiti emamirimita mafungu kuti uwane yechokwadi 5G kumhanya.
