Transmission/reception apparatus, transmission/reception method, and transmission/reception system

摘要

Information on the protocols supported by a target device and the address thereof are acquired by a simple operation, and communication is performed using a supported protocol. A device (1) 1 includes: a non-contact IC interface 2, which requests supported protocol information 8 of a device (2) 4 within a predetermined communication area in a network, and which acquires supported protocol information 8 from the device (2) 4; an IEEE 802.11b interface 3, which performs transmission signal processing and reception signal processing; test communication element, which performs test communication using the IEEE 802.11b interface 3; and communication element which, when test communication using the test communication element is possible, performs communication using a protocol of the protocol information 8 acquired by the protocol acquisition element.
