0.1(NDL–NOffs-DL)=2570+0.1（38050-37750）=2600，前提已知频点为38050来计算频率. | | | | | | | | | | 频点的计算公式For Eaxmple:NDL = 10 (FDL–FDL_low )+NOffs-DL= 10 (FDL–2750)+ 37750 =EARFCN = 10 (2580–2570) + 37750 = 37850，前提已知中心频率为2580 | | | | | | | | | | 频点和频率换算说明：FDL为中心频率，NDL为信道号，即频点，FDL_low为下行起始频率，NOffs-DL为下行的起始频点. | | | | | | | | | | 备注说明： | 　 | 　 | 　 | 　 | 　 | 　 | 　 | 　 | | LTE可以配置频点的频带宽度是可以有多种选择的，1.4M/3M/5M/10M/15M/20MHz。D频段的起始频点是37750，如果使用10MHz的话，中心频点是37800。第二个频点的中心频点是第一

个中心频点的37800+100=37900。如果使用20MHz的话，第一个频带的中心频点是37750+100=37850。第二个频点的中心频点是37850+200=37950。把频带的初始频点记住了，后面的
中心频点根据频带宽度就可以计算出来了。 | | | | | | | | | | | | | | | | | | | | | | Remark | | | | | | | | | | • Networks on LTE-bands 1, 3, 7, 28 (FDD-LTE) or 38, 40 (TDD-LTE) are suitable for future global roaming in ITU Regions .
