Abstract
An asymmetric gain communication device and the communication method thereof are provided. With at least one receiving antenna and a transmitting antenna with different antenna gains, the antenna gains of the receiving antennas being greater than the antenna gain of the transmitting antenna and different from each other, the invention detects the communication signals of the receiving antennas for recording communication quality thereof. The mechanism switches in real time to an appropriate receiving antenna according to the received communication quality. This mechanism optimizes the signal transmission distance and communication stability.
