最近準備幫長輩換手機~目前考慮4G吃到飽~
上了手機王網頁發現4G有兩種
4G FDD LTE
4G TDD LTE
根據個人在網頁上看了部分資料後
只有大致明白
想跟各位前輩請教的部分是
手機王在這兩個4G的模式後面還有註明很多頻率
表示這支手機支援的頻段
例如:M812
4G FDD LTE 900(B8), 700(B28), 1800(B3), 2100(B1), 2600(B7)
4G TDD LTE 2500(B41), 2600(B38)
當然我有事先查了一下資料
以台灣目前開放的頻段來說只有700,900,1800,2600四種
所以想請問
1.上述例子不管是FDD的2100(B1)或是TDD2500(B41)都是可以直接略過不看的對嗎??
2.某些業者有缺少部分頻段的話我也可以選擇不支援該頻段的手機以適用嗎?
例如台哥大沒有900跟2600頻段~我要攜碼至台哥大時手機即便不支援此兩頻段也無所謂,因為他們本來就沒有提供這兩個頻段對嗎??
將來有沒有可能再次釋出這兩個頻率的頻寬競標??如果有的話我應該還是要選擇有支援的未雨綢繆一下??
3.上述各頻段後面有個括弧~括弧裡面的英文跟數字分別代表甚麼意思呢??
請各位前輩幫忙解惑~萬分感謝
