FREQUENCY BAND SWITCHING SYSTEM, FREQUENCY BAND SWITCHING METHOD, AND FREQUENCY BAND SWITCHING PROGRAM

摘要

To provide a frequency band switching system comprising a mechanism that not generate a failure in a band steering.SOLUTION: A wireless LAN router device 10 has a function that is available to use two frequency bands, and switches each frequency band of each slave terminal 20, and monitors a jam rate in each frequency band in each prescribed period by a jam rate management part 7, and calculates an average jam rate per previous day. The wireless LAN router device 10 predicts a jam level in each frequency band of the current day on the basis of the average jam rate per previous day in each frequency band, and determines the frequency band of the current day to which each slave terminal belongs. When it is detected that the slave terminal 20 belongs to the frequency band other than the frequency band of the current day determined, the execution of a band steering to the frequency band of the current day determined is instructed for the slave terminal 20 at the timing of detecting that the slave terminal 20 is in a no-communication state.SELECTED DRAWING: Figure 1
