Iyo C-band, radio spectrum ine frequency range pakati pe3.4 GHz ne4.2 GHz, inoita basa rakakosha mu5G network. Hunhu hwayo hwakasiyana hunoita kuti ive kiyi yekuwana yakakwirira-kumhanya, yakaderera-latency, uye yakakura-yekuvhara 5G masevhisi.
1. Balanced coverage uye transmission speed
Iyo C-bhendi ndeyepakati-bhendi spectrum, iyo inogona kupa yakaringana pakati pekuvhara uye data yekumhanyisa kumhanya. Kuenzaniswa ne-low-band, iyo C-bhendi inogona kupa yakakwirira data data rates; uye zvichienzaniswa nepamusoro-frequency mabhendi (akadai semillimeter waves), C-bhendi ine chivharo chakafara. Chiyero ichi chinoita kuti C-bhendi inyatsokodzera kuendesa 5G network munzvimbo dzemumadhorobha uye dzemudhorobha, kuve nechokwadi chekuti vashandisi vanowana hupamhi hwekumhanya uku vachidzikisa huwandu hwezviteshi zvepasi zvakaiswa.
2. Yakawanda spectrum zviwanikwa
Iyo C-bhendi inopa yakakura spectrum bandwidth kutsigira yakakura data huwandu. Semuyenzaniso, Federal Communications Commission (FCC) yekuUnited States yakapa 280 MHz yepakati-bhendi spectrum ye5G muC-bhendi ndokuitengesa pakupera kwa2020. Vashandisi vakaita seVerizon neAT&T vakawana huwandu hukuru hwema spectrum. zviwanikwa mune iyi auction, ichipa hwaro hwakasimba hwemasevhisi avo e5G.
3. Tsigira teknolojia yepamusoro ye5G
Iyo frequency maitiro eiyo C-bhendi inoita kuti ikwanise kutsigira zvakakosha matekinoroji mu5G network, senge hombe MIMO (yakawanda-inopinza-yakawanda-yakabuda) uye beamforming. Aya matekinoroji anogona kuvandudza spectrum kunyatsoita, kuwedzera network network, uye kugadzirisa mushandisi ruzivo. Uye zvakare, iyo bandwidth mukana weC-bhendi inoita kuti isangane nepamusoro-kumhanya uye yakaderera-latency zvinodiwa zveramangwana 5G maapplication, akadai augmented real (AR), chaiyo chaiyo (VR), uye Internet yezvinhu (IoT). )
4. Wide application pasi rose
Nyika zhinji nematunhu vakashandisa iyo C-bhendi seyo huru frequency bhendi ye5G network. Semuenzaniso, nyika zhinji dzeEurope neAsia dzinoshandisa n78 band (3.3 kusvika 3.8 GHz), nepo United States inoshandisa n77 band (3.3 kusvika 4.2 GHz). Uku kuenderana kwepasirese kunobatsira kuumba yakabatana 5G ecosystem, kukurudzira kuenderana kwemidziyo uye matekinoroji, uye kukurumidza kufarirwa uye kushandiswa kwe5G.
5. Kurudzira 5G kutengesa kutengesa
Kuronga kwakajeka uye kugoverwa kweC-band spectrum kwakakurumidza kutengesa kushandiswa kwe5G network. KuChina, Bazi reIndasitiri neRuzivo rweTekinoroji rakadoma zvakajeka 3300-3400 MHz (kushandiswa kwemukati musimboti), 3400-3600 MHz uye 4800-5000 MHz mabhendi semabhendi anoshanda e5G masisitimu. Kuronga uku kunopa gwara rakajeka rekutsvagisa nekusimudzira uye kushambadzira kwemidziyo yehurongwa, machipisi, materminals uye bvunzo zviridzwa, uye inosimudzira kushambadzira kwe5G.
Muchidimbu, iyo C-bhendi inoita basa rakakosha mu5G network. Zvakanakira mukuvhara, kumhanya kwekutapurirana, zviwanikwa zve spectrum uye tsigiro yehunyanzvi inoita kuti ive hwaro hwakakosha hwekuzadzikisa chiono che5G. Sezvo kufambiswa kwepasi rose kwe5G kunofambira mberi, basa reC-bhendi richawedzera kukosha, richiunza vashandisi ruzivo rwekutaurirana rwuri nani.
