Abstract:
1. A communications method, comprising: performing testing and calibration of a communication terminal to obtain more than two sets of radio frequency (RF) parameters corresponding to a normal radiation index, a second radiation index, and a third radiation index for an antenna, wherein the normal radiation index causes a wireless communications device to produce electromagnetic interference that deteriorates hearing aid connection quality and wherein at least one of the second radiation index and the third radiation index restricts the wireless communications device from producing electromagnetic interference that deteriorates hearing aid connection quality below an acceptable hearing aid threshold level; storing said more than two sets of RF parameters; calling one of the said more than two sets of RF parameters corresponding to a selected radiation index for switching; dynamically switching between the more than two sets of RF parameters without user input using a single circuit; and selecting, by user input, an additional set of RF parameters from the more than two sets of RF parameters; uploading the additional set of RF parameters selected by the user input; when the switching is successfully completed, configuring RF parameters corresponding to the selected radiation index to a plurality of transmission modules for communications, wherein the plurality of transmission modules define a single circuit including a baseband chip, a RF transceiver and a power amplifier and wherein the normal radiation index, the second radiation index and the third radiation index are associated with the same antenna, and wherein the baseband chip of the single circuit is configured using the additional set of RF parameters selected by the user to selectively produce the normal radiation index.
