1. Abstract
This manual provides specifications for the EE200 electronic shelf label (hereafter referred
to as “ESL”).
2. Overview
The EE200 is an E-ink based ESL with a 2.4GHz radio for data communication. This
product uses Direct Sequence Spread Spectrum RF technology that allows for an ultra-low
power consumption combined with a reduced sensitivity to background noise. That means
less interference by other radios that operate in the 2.4GHz band. The radio protocol that is
used is based on the IEEE 802.15.4 standard that specifies the physical layer and media
access control for low-rate wireless personal area networks. The protocol is entirely
implemented, except for some small changes that have all to do with the connection
protocol to a base station. When the base station is not available the EE200 switches to a
non-802.15.4 standard to lower the power. That is especially meaningful when the EE200 is
not being used for a prolonged period of time (e.g. during shipping)
A development kit is available that consists out of a base station and several EE200 tags
plus a PC demo application that allows people to quickly test the system and makes it
easier to integrate this ESL system into an existing back office system.
