Abstract: An automatic-switching wireless communication system and method, comprising: a first device, and a second device. The first device verifies if said second device has paired with itself through using near end wireless communication. If an answer is positive, the second device connects with the first device by near end wireless communication and requests first device to activate remote end wireless communication. Then, second device searches to find a remote end wireless communication module of the first device. In case it is found, the first device is used as a wireless base station, such that the first device and the second device transmit data by remote end wireless communication, and the second device is connected to an outside network through the first device. If the second device is outside a range of the near end wireless communication of the first device, said remote end wireless communication module is closed automatically.
