Ngo-2020, ngokubambisana ne-Huawei e-China, sizobamba iqhaza ekwakhiweni kwezinkulungwane zeziteshi zamaselula ezingenantambo seziphelele, phakathi kwazo sizohlinzeka ngezihlukanisi zamandla we-microstrip ezinamafrikhwensi angu-0.5/6g kanye no-1-50g njengezingxenyekazi zekhompyutha ezisekelayo.
Ukufakwa okwengeziwe kwemishini yesiteshi samaselula angenazintambo kuzobandakanyeka ngo-2021, futhi inani eliphelele kulindeleke ukuthi lidlule amashumi ezinkulungwane zamadivayisi.
Amabhendi amafrikhwensi afanele ukuxhumana ngesathelayithi
Isikhathi: 2021-10-28
I-ITU ichaza amabhendi okuvama, asetshenziselwa ukuxhumana ngesathelayithi.
I-UHF (Ultra High Frequency) noma i-decimeter wave frequency band, ibanga lokuvama lingu-300MHz-3GHz.
Le bhendi yefrikhwensi ihambisana ne-IEEE UHF (300MHz-1GHz), L (1-2GHz), kanye ne-S (2-4GHz) yamabhendi.
Amaza omsakazo webhendi ye-UHF aseduze nokusakazeka komugqa wokubona, avinjwe kalula izintaba nezakhiwo, njll., futhi ukuncishiswa kokudluliselwa kwangaphakathi kukhulu uma kuqhathaniswa.
I-SHF (i-Super High Frequency) noma ibhande lemvamisa yesentimitha, ibanga lemvamisa ngu-3-30GHz.
Le bhendi yefrikhwensi ihambisana ne-IEEE S (2-4GHz), C (4-8GHz), Ku (12-18GHz), K (18-27GHz) kanye ne-Ka (26.5-40GHz) yamabhendi.
Amaza amadesimitha anobude obuyi-1cm-1dm, futhi izici zawo zokusakazeka ziseduze namaza okukhanya.
I-EHF (I-Extremely High Frequency) noma ibhendi yefrikhwensi ye-millimeter wave, ibanga lefrikhwensi ngu-30-300GHz.
Le bhendi yefrikhwensi ihambelana ne-IEEE's Ka (26.5-40GHz), V (40-75GHz) namanye amabhendi efrikhwensi.
Amazwe athuthukile aqale izinhlelo zokusebenzisa amabhendi efrikhwensi angu-50/40GHz Q/V emasangweni esevisi yesathelayithi egxilile yomthamo omkhulu (i-HDFSS) lapho izinsiza ze-Ka-band nazo ziba nzima.
Singakwazi futhi ukwenza ngokwezifiso izingxenye ze-rf passive ngokuya ngezidingo zakho. Ungafaka ikhasi lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
