以前大家都一直很看好5G
認為智慧型手機的銷量已經進入高原期
要能有爆發性的突破
唯有5G商轉!
請問這個論點
大家同意嗎??
但日前華為的CEO說
大多數消費者不會注意到5G技術的好處,運營商將很難從中獲利,消費者不會發現5G與4G技
術之間存在實質性差異
這樣說來,5G只是一個被炒作起來的技術規格
而且5G主要的特點是使用高頻電磁波
雖然傳輸頻寬大,但用sub-6GHz來傳,速率提高不夠顯著
要是用毫米波來傳,速率提高upup,廣設基地台對營運商簡直是不可能的任務
所以有些人覺得5G的商業模式遲早會大崩壞的
大家同意嗎??
我朋友又說,不能向前相容的5G獨立網路(Stand alone),語音電話沒辦法切到電路交換網
路,變成要走類似VoLTE的模式,會讓營運商先前投資的4G網路毫無用武之地,根本不可能有
營運商要推,真的是這樣嗎
