In a system for data communication between an information terminal to be operated by a user and remote communication nodes, the present invention intends to suppress the power consumption of the information terminal. For that purpose, communication nodes 2, 3 and 4 each emit diffuse light carrying a pilot signal blinking at a low frequency to notify the presence of the communication node and an ID signal belonging to a higher frequency range, the ID signal containing inherent address etc. for identifying each communication node.

This information is used to identify each node and eliminate influences of any other light source that apparently resembles the pilot signal.
