Abstract

A wireless communication system comprises a host and a device. The host is provided with a communication unit capable of data communication using a first communication system and a second communication system which is higher in maximum transmission rate than the first communication system, and without regard to any communication system to be used by the device, the host uses the first communication system to start processing for establishment of a communication link with the device.

Claims

1. A wireless communication system for performing data communication between a host and a device, wherein

the host is provided with a communication unit capable of data communication using a first communication system and a second communication system which is higher in maximum transmission rate than the first communication system, and

without regard to any communication system to be used by the device, the host uses the first communication system to start processing for establishment of a communication link with the device.

2. A wireless communication system for performing data communication between a host and a device, wherein

the host is provided with a communication unit capable of data communication using a first communication system and a second communication system which is higher in maximum transmission rate than the first communication system, and

the host uses the first communication system to start processing for establishment of a communication link with the device.

3. The wireless communication system according to claim 2, wherein

the processing for establishment of the communication link includes transmitting a beacon signal from the host to the device by the first communication system.

4. The wireless communication system according to claim 3, wherein

upon receiving the beacon signal, the device transmits to the host a device information containing information indicative of a communication system to be used by the device, and

based on the device information received, the host performs data communication with the device by the second communication system in place of the first communication system.
