Abstract
A selective blocker for targeted mobile terminals. A signal monitor determines when a targeted mobile terminal is transmitting a signal to a base station. A signal analyzer identifies characteristics of the terminal signal and a processor produces a blocking response based on one or more characteristics. The blocking response is transmitted to the targeted mobile terminal to block communications between the targeted mobile terminal and the base station using the minimum power needed to effectively block the terminal signal so as to limit interference with non-targeted mobile terminals.
