DATA COMMUNICATION METHOD AND DATA COMMUNICATION EQUIPMENT

摘要

PURPOSE:To realize simultaneous multiplex communication by (n) to (n) and to reduce mutual interference among communication signals so as to speed up data transmission speed on data communication method/device by radio using an electromagnetic wave having a frequency higher than a milimeter wave as a carrier. CONSTITUTION:Transmission devices l narrow the outgoing angles 3 electromagnetic waves transmitted to respective reception devices 2 and irradiate diffusion areas 5 different in curve surfaces with the waves. The respective reception devices 2 receive the electromagnetic waves of self devices, which are diffused in the respective areas of the curve surfaces. The transmission devices 1 change the outgoing direction of the electromagnetic waves where the outgoing angles 3 are narrowed so as to irradiate the curve surfaces with the waves. The respective reception devices 2 respectively receive the electromagnetic waves of the self devices, which are reflected on the curve surfaces. The transmission devices narrow the outgoing expansion angles of the electromagnetic waves of the reception devices and emit light to the direction of the facing reception devices between the facing transmission devices and reception devices.
