The present invention provides a method, apparatus and system for treating fire ant mounds. The resultant composition has improved radiation screening properties. The interfering Node B may avoid transmitting on the allocatedprotected resources, but transmissions from the interfering Node B on resources not allocated to the serving Node B may cause significant interference on cell-specific reference signal tones of the serving Node B. In either case, once the trigging system situation has returned to normal, the memory reverts to the normal operation. Moreover, the gain of the sensor is dynamically controlled in response to the above estimation result.
