When, if WIFI is enabled, the registration frequency point information scope provided according to digital independent control module, radio frequency
The WIFI wireless modes selection 2.4G frequency ranges such as 802.11b/g/n of chip, due to now hf channel
It can use, thus, WIFI signal inputs tremendously high frequency antenna by hf channel feed point, by the 2.4G of high frequency antenna
Frequency range is realized transmitting and received.
In the present embodiment, by judging registration frequency whether in the range of low frequency band, to select to disconnect also
Radio frequency path is to maintain to the connection of low channel；If not in the range of low frequency band, disconnecting radio frequency
The connection of low channel is routed to, so as to start LTE high-frequency works, i.e., control instruction controls LTE high frequency
Signal by hf channel feed point input tremendously high frequency antenna, by high frequency antenna high-frequency band for example
2300MHz~2600MHz frequency ranges are realized transmitting and received；Now, if WIFI is enabled, then according to
