Abstract
A power management system is disclosed in which ESL labels communicate with a server through a base station. The frequency and times at which each ESL label communicates with the server is optimized for the minimum communication necessary to provide up to date pricing and related information, and to simultaneously minimize consumed battery power for the ESL labels. The base stations and servers for the system are preferably operated from hard wired power.
