EE201 Specifications manual

1. Abstract
This manual provides specifications for the EE201 electronic shelf label (hereafter referred to as
“ESL”).
2. Overview
The EE201 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 EE201 switches to a non-802.15.4 standard to lower the power.
That is especially meaningful when the EE201 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 EE201 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.
