Which of the following statements about global calibration algorithms are TRUE? (Multiple Choice)
A . The core of the Dynamic Channel Allocation (DCA) algorithm is the exhaustion and iteration algorithms, which list all possible AP-Channel combinations and choose the optimal combination.
B . The Transmit Power Control (TPC) algorithm aims to choose a proper transmit power which can meet coverage requirements of an A
D . Interference specified by the lower interference threshold is low, and within the allowed range. Two neighbor APs cannot detect interference from each other and can send packets simultaneously.
E . If the interference caused by a neighbor is smaller than the lower interference threshold, the algorithm determines whether to reduce the transmit power according to the difference between the interference caused by the neighbor and the lower interference threshold.
Answer: AC
