PROBLEM TO BE SOLVED: To provide an electronic display system in which an electronic display terminal can perform stable communication with an information distribution device, even when radio wave interference occurs.SOLUTION: Electronic display terminals 50a-50d, ... display arbitrary information. Access points 10a-10f, ... distribute the arbitrary information to the electronic display terminals 50a-50d. Each of the access points 10a-10f, ... has: a transmission part 13 for transmitting a beacon B; and a transmission part 14 of a mask signal M for blocking that the beacon B transmitted from other access points 10a-10f, ... is received by the electronic display terminals 50a-50d, .... The beacon B having information related to the device itself is a signal configured by a plurality of unit beacon signals b1-b5, ... which continue in a predetermined cycle Tm. The mask signal transmission part 14 transmits unit mask signals m1-m4, ... between continuous unit beacon signals b1-b5, .... |
