提问者: • 电信LTE RSRP正常，SINR很差，电信1.8G频段的，频点1825,1850 2020-07-21
• 某地市移动公司和联通的在904-909M频段有干扰，经现场扫频测试，干扰源是移动设备出来的，通知移动闭站，检查频点，处理过干扰消失。不知道怎么干扰经常出现 2020-06-29
• 2110是什么频点 2020-05-19
• LTE中RB具体频点号计算？ 2020-04-25
• 公网小区已添加铁路专网频点黑名单（PCI-n8），但还是发生了重选 2020-04-16
• LTE同频切换判决中是否计算本小区频点对应的频率偏置qoffset? 2020-03-10
• 扩展频点是什么？ 2019-12-26
比如下行频点时1650，那么它的频段和上行频点怎么得到！d
//计算公式还是一样啊
通过表格可以看到 1650属于band 3
根据公式 FDL = FDL_low + 0.1(NDL – NOffs-DL)
从表格可以看到FDL_low =1805 Noffs-DL=1200
那么频率Fdl=1805+0.1*(1650-1200)=1805+45=1850MHZ

下行频点计算公式：FDL = FDL_low + 0.1(NDL–NOffs-DL)
其中FDL为该载频下行频点，FDL_low对应频段的最低下行频点，NDL为该载频下行频点号，NOffs-DL对应频段的最低下行频点号。
上行频点计算公式：FUL = FUL_low + 0.1(NUL–NOffs-UL)
其中FUL为该载频上行频点，FUL_low对应频段的最低上行频点，NUL为该载频上行频点号，NOffs-UL对应频段的最低上行频点号。
