摘要： A communication device is disclosed, having a transceiving circuit, a timer circuit, and a control circuit. The transceiving circuit is used to transceive frequency hopping signals according to at least part of good channels in a channel map. The timer circuit is used to calculate a timespan of one or more communication intervals in which the transceiving circuit transceives the frequency hopping signals. The control circuit is used to compare the timespan with a time threshold to determine whether signal transmission tests with one or more bad channels in the channel map should be performed to update the channel map.

摘要： A cellular phone to be investigated is placed within an RF shielding bag that is formed with conductive materials. A computer transmits investigation commands to a data acquisition device to obtain data stored in the cellular phone. An RF emitter also placed within the RF shielding bag is coupled between the data acquisition device and the cellular phone. At least a portion of a signal line connecting the data acquisition device to the RF emitter is outside the RF shielding bag and may act as an antenna that transmits unwanted RF signals to the cellular phone. The RF emitter corrupts such incoming RF signals not shielded by the RF shielding bag. This helps ensure a forensic sound investigation of the cellular phone.
