An electronic shelf system includes a shelf, a first display unit, a first sensing unit, a storage unit and a processing unit, wherein the processing unit communicates with the first display unit, the first sensing unit and the storage unit. The shelf includes a compartment. The first display unit is disposed on the compartment. The first sensing unit is disposed on the shelf. The first sensing unit is configured to sense a characteristic parameter. The storage unit stores a plurality of display information. The processing unit receives the characteristic parameter from the first sensing unit and controls the first display unit to switch one of the display information being displayed currently to another one of the display information according to the characteristic parameter.

Electronic shelf system

A method for determining stability of a wireless signal includes transmitting a plurality of transmitted testing signals periodically during a time interval, receiving the plurality of transmitted testing signals and identifying at least one received testing signal from the plurality of transmitted testing signals, and generating a signal stability indicator according to a time weighting of each received testing signal of the at least one received testing signal.
