Abstract
A radio frequency (RF) signal control module is provided. The RF signal control module includes a detection and control device detecting at least one radio coupling value in a transmission band according to a radio coupling signal and generating a control signal for controlling transmission power an RF signal to be transmitted according to the detected radio coupling value.
Claims19
A radio frequency (RF) signal control module, comprising:
- a detection and control device, detecting at least one radio coupling value in a transmission band according to a radio coupling signal and generating a control signal for controlling transmission power of an RF signal to be transmitted according to the detected radio coupling value.
A radio frequency (RF) signal controlling method, comprising:
- detecting an amount of change of a radio coupling value according to a radio coupling signal;
- determining whether the amount of radio coupling value change has exceeded a predetermined threshold;
- and
- limiting a maximum transmission power of an RF signal to be transmitted or lowering a transmission power of an RF signal to be transmitted by a level when the amount of radio coupling value change has exceeded the predetermined threshold.
