System and method for electronic labels, electronic labels, and gateway devices

A method for an electronic label, comprising the following steps:

• providing at least one electronic label, a first base station (BS), a second BS and an access point (AP), wherein the first BS has an identifier (ID) and a first wireless transmission channel, the first BS transmits a first wireless signal having the first signal strength and effective in a first area, the second BS has the ID and the first wireless transmission channel and transmits a second wireless signal having the second signal strength and effective in a second area, the AP has a second wireless transmission channel to communicate with the first and the second BSs to allocate time slot schedules to the first BS and the second BS, and the at least one electronic label is configured in at least one of the first area and the second area;
• receiving the first wireless signal from the first BS during a first time period, and receiving the second wireless signal from the second BS during a second time period;
• determining whether the at least one electronic label conducts transmission with the first BS or the second BS on the first wireless transmission channel according to which one of the first signal strength and the second signal strength is stronger;
• and
• receiving a time slot schedule from at least one of the first BS and the second BS, wherein according to the time slot schedule, the at least one electronic label conducts transmission with the first or second BS on the first wireless transmission channel.
