A quantity of antennas included in the antenna assembly is greater than a quantity of receive antennas supported by customer premises equipment (CPE). Therefore, when a network changes, the CPE may select, from a plurality of antennas included in the antenna assembly, a quantity of antennas with relatively good data transmission performance as receive antennas, where the quantity is the same as the quantity of receive antennas supported by the CPE. That is, the CPE may not need to adjust directions of antennas, but select, from a redundant quantity of set antennas, antennas with relatively good receiving performance to ensure that the CPE is aligned with a direction with relatively good signal quality.
