<p>Provided is a data communication system which can improve sensitivity of a receiver by suppressing a flow-out of an electric field fed to a human body from a field communication transmitter to the ground from the human body and can suppress generation of a crosstalk between a user and a neighbor carrying a field communication transmitter. The data communication system includes: a mobile device (1a) as a user side communication device; a fixed device (3) as a fixed side communication device for exchanging an information signal with the mobile device (1a) using as a transmission path, a human body (2) located at a predetermined position; a high-impedance floor portion (5) installed in the vicinity (R1) of a user who puts a hand above the fixed device (3); and low-impedance floor portions (6a, 6b) arranged in peripheral regions (R2, 3).</p> |
