1880M.Default difference is 5, and it is respectively the first hair that the first transmission frequency range receives immediate two frequency ranges in frequency range with second
Send 1879 in frequency range, with second receive in frequency range 1880, first is sent in frequency range and 1879 subtracts 5, obtains 1874, by the
1880 in two reception frequency ranges add 5, obtain 1885, then using 1874 to 1885 as successive bands.
It can be controlled by processor that whether bandstop filter, which carries out trap processing, and processor can control when to allow band to hinder
Wave filter works.Specifically, processor can first determine the first radio-frequency module and the second radio-frequency module whether and meanwhile work, if
Be, then determine the first radio-frequency module the first transmission frequency range and the second radio-frequency module the second receiving module whether and meanwhile work,
If it is, control bandstop filter work, that is, control bandstop filter to pre- in the radiofrequency signal waiting for transmission that receives
If the radiofrequency signal of frequency range carries out trap processing.
Processor determine two radio-frequency modules whether and meanwhile work, and determine first send frequency range with second receive frequency range
Simultaneously whether the process of work belongs to prior art, in embodiments of the present invention without repeating.
