Patent number: 9831923Abstract: A communication system and communication method enable various types of near field communication. NFC communication apparatuses have two features in that each can perform communication in two communication modes and that each can perform data transmission at a plurality of transfer rates. The two communication modes consist of a passive mode and an active mode. In the passive mode, between the NFC communication apparatuses, for example, a first NFC communication apparatus transmits data to a second NFC communication apparatus by modulating electromagnetic waves generated by itself, while the second NFC communication apparatus transmits data to the first NFC communication apparatus by performing load modulation on the electromagnetic waves generated by the first NFC communication apparatus. Alternatively, in the active mode, either of the NFC communication apparatuses transmits data by modulating electromagnetic waves generated by itself.Type: GrantFiled: October 19, 2016Date of Patent: November 28, 2017Assignee: SONY CORPORATIONInventors: Yoshihisa Takayama, Susumu Kusakabe, Kazushige Tsurumi, Tadashi Morita, Kunihide Fujii
