Abstract
Provided is a communication device including a contactless communication unit that conducts contactless communication, a wireless communication unit that conducts wireless communication, and a control unit that, in a case in which the contactless communication unit detects another communication device, controls activation start of a first communication mode of the wireless communication unit, and controls a connection process for the wireless communication between the contactless communication unit and the other communication device.
Claims6
A wireless communication device, comprising:
- an antenna interface for connecting to an antenna for wireless communication;
- a host controller interface for connecting to a host controller, the host controller further connecting to a contactless communication device for contactless communication;
- and
- a control unit configured to discover a wireless communication apparatus through the host controller interface, to start activation of a direct communication mode and to conduct a negotiation about roles during the activation of the direct communication mode, such that the negotiation about roles is performed by contactless communication in parallel with the activation of the direct communication mode by wireless communication.
