It is found that the upper limit of the operational frequency bandwidth along the short great circle path which crosses the south-polar, region is approximately in accord with the calculated MUF and the other one along the long great circle path which crosses the north- polar region is different from the calculated MUF.

结果表明，经过南极区的短大圆路径的通信频段上限与计算的MUF基本相符；经过北极的长大圆路径的通信频段上限与计算的MUF有偏差。
