电信LTE分到的频段：
UL1755-1785MHz
DL1850-1880MHz
目前使用的是1765-1780和1860-1875（B3频段）
LTE频点计算公式
下行频点计算公式：
F DL=F DL_low+0.1(N DL–N Offs-DL)
1867.5=1805+0.1（N DL–1200）
其中F DL为该载频下行频点(所使用频段的中心频率，即1867.5），F DL_low对应频段的最低下行频点（B3频段对应的是1805），N DL为该频段下行频点号（即所求频点），N Offs-DL对应频段的最低下行频点号（B3频段对应的是1200）。对应关系表详见表1。
上行频点计算公式：
F UL=F UL_low+0.1(N UL–N Offs-UL)
其中F UL为该载频上行频点，F UL_low对应频段的最低上行频点，N UL为该载频上行频点号，N Offs-UL对应频段的最低上行频点号。对应关系表详见表1
上下行频点号范围：0-65535.
对应关系表详见表1如下：
