非專家, 以下是我亂想的.
我認為5G可能會改變軟體的實作方式.
以前cpu速度可以靠著摩爾定律每幾年提升一倍, 直到遇到瓶頸後cpu朝向多核心發展,
因此工程師需要學習各式各樣的多執行緒開發知識.
那如果因為5g的高傳輸低延遲特性, 現在開發新軟體產品應該要規劃10年的產品藍圖.
例如本版會使用到的看盤軟體, 因為桌機和手機的cpu效能和記憶體容量差異大, 加上
受限網路延遲還不夠即時, 因此常常是拉一份資料回來本機, 然後利用客戶的電腦計
算出其他指標, 對客戶的硬體配置要求較高, 但手機因為效能記憶體和耗電因素無
法這樣做, 所以桌機和手機的資料不一樣多, 看盤體驗不一致, 但如果未來不管
什麼頻率的K線或其他股票資料都可以經由user電腦(client)下指令, 遠端server
運算後回傳, 那client的計算負擔減少, 看盤體驗就會一致, 例如桌機有某個需
要大量運算的指標, 手機目前因為資源做不到就可以解決.
搞不好client用HTML5寫瀏覽器上的看盤軟體就足夠, 因為不用過多計算純顯示,
不用每種作業系統都寫一份code造成維護困難, 是不是RD的負擔會減少, 也可以
達到跨平台體驗一致的效果.
