台灣的LTE即將上市，但在既有的環境下，其使用者真的能得到號稱100Mbps的上網速度嗎?

依據底下規格與公式，手機若在LTE FDD 10MHz的情況下，其在10MHz裡有 50RB,每個RB都可獲得 MCS =28，則此時手機在下載資料時，每秒只可最高可獲得 36Mbps 速度.....要達到100Mbps 請用兩根天線與20Mhz再說

PHY layer throughput in bits = Transport Block Size (bits) / subframex number of transport blocks / subframex 1000 subframes / sec = ???? bits/sec

Let's assume that RB is 100 (20MHz) FDD Mode

If we use 2 antenna, the throughput is 51024 bits * 2 transport blocks * 1000 subframes/sec = about 100 Mbps

The basic type 1 LTE frame has an overall length of 10 ms. This is then divided into a total of 20 individual slots. LTE Subframes then consist of two slots - in other words there are ten LTE subframes within a frame
