Ukuxhumana okubalulekile kubhekisela ekushintshaneni kolwazi olubalulekile ekusebenzeni nasekuphepheni kwabantu ngabanye, izinhlangano, noma umphakathi uwonke. Lokhu kuxhumana kuvame ukuzwela isikhathi futhi kungabandakanya iziteshi nobuchwepheshe obuhlukahlukene. C...

Isixhumi se-coaxial se-RF siyingxenye efakwe kukhebula noma ithuluzi, idivayisi ye-elekthronikhi esetshenziselwa ukuxhuma ugesi noma ukuhlukanisa ulayini wokudlulisa, futhi siyingxenye yolayini wokudlulisela, lapho izingxenye (amakhebuli) adlulisa khona. .

Njengamanje, ngokuthuthuka kancane kancane kwezinhlelo ze-StarLink, i-Telesat, i-OneWeb kanye ne-AST ye-AST's, ukuxhumana kwesathelayithi okujikeleza kancane kuyakhuphuka futhi. Isicelo "sokuhlanganisa" phakathi kwezokuxhumana ngesathelayithi namaselula asemhlabeni...

Ingqungquthela yesi-4 ye-Western Microwave ye-IME2022 ibibanjelwe ngokomkhosi e-Chengdu. Njengomhlangano omkhulu wama-microwave, i-millimeter-wave nama-antenna anethonya lemboni esifundeni sasentshonalanga, Ingqungquthela yalo nyaka ye-Western Microwave iqhubekile nokwandisa ...

1） I-RF front-end iyingxenye ewumnyombo yesistimu yezokuxhumana Ingaphambili lefrikhwensi yomsakazo inomsebenzi wokwamukela nokudlulisa amasignali amaza omsakazo. Ukusebenza kwayo nekhwalithi yizici ezibalulekile ezinquma amandla esignali, inethiwekhi c...

I-LoRa imfushane ku-Long Range. Ibanga eliphansi, ubuchwepheshe bokuxhumana eduze nebanga lebanga. Kuwuhlobo lwendlela, isici sayo esikhulu okuyibanga elide lokudluliswa okungenantambo ochungechungeni olufanayo (i-GF, i-FSK, njll.) esabalele kakhulu, inkinga ye-meas...

Yaziswe uMnyango Wezimboni Nobuchwepheshe Bolwazi wase-China: I-China ivule iziteshi eziyisisekelo ze-5G eziyizigidi ezingu-1.425, futhi kulo nyaka izothuthukisa ukuthuthukiswa okukhulu kwezinhlelo zokusebenza ze-5G ngo-2022. kuzwakala sengathi i-5G iyangena ngempela empilweni yethu yangempela, s. ..

I-4G ishintsha impilo, i-5G ishintsha umphakathi, ngakho-ke i-6G izobashintsha kanjani abantu, futhi izolethani kithi? U-Zhang Ping, isifundiswa se-Chinese Academy of Engineering, ilungu leKomidi Lokweluleka le-IMT-2030(6G) Group Promotion, kanye noprofesa e-Beijin...
