Title:
無線通信方法
Document Type and Number:
Japanese Patent JP5499204
Kind Code:
B2
Abstract:
To provide a wireless communication method in the case where communication of a wireless signal from a communication device to a semiconductor device can be ensured, communication of a wireless signal can be ensured without using a repeater even when communication of a wireless signal from a semiconductor device to a communication device is difficult due to an external factor such as an obstacle. A plurality of semiconductor devices operate in selectively switching between a first state in which the first wireless signal transmitted from the communication device is received and a second state in which the second wireless signal transmitted from the semiconductor device is received. The semiconductor device in the second state receives the second wireless signal from the semiconductor device in the first state and transmits to the communication device the second wireless signal including detection data for indicating that the second wireless signal is received.
