1 Abstract
This manual provides specifications for the EE-290 Electronic Shelf Label (hereafter referred to as
“ESL”).
2 Overview
The EE-290 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 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.
A development kit is available that consists out of a base station, several ESL tags and PC software
that allows people to quickly test the system and makes it easier to integrate this ESL system into an
existing back office system.

7 Electrical Specifications
7.1 Electrical Characteristics
Conditions: Operating voltage 3.0V unless otherwise specified
The ESL is in sleep mode almost the entire time. The device wakes up at regular intervals
(called the poll time) and it then transmits a poll request to the base station. When the base
station has no data to send, it acknowledges the poll after which the ESL immediately goes
back to sleep. The minimum poll rate is configurable and is set to 20 seconds by default. A
higher poll rate will decrease the power consumption but will increase the response time.
7.2 Battery
The power is supplied to the ESL by 2 CR2450 batteries:
• Nominal capacity: 1200 mAh (two times 600mAh)
• Nominal voltage: 3.0 V.
• Maximum self-discharge rate: <1% per year
• Usable time: 7 years minimum (Update frequency: 4 times per day, poll time 20 seconds)
The operating time of the batteries is based on any of the following factors that influence the
battery life:

* The correlation shows whether increasing the listed value increases or decreases the power
consumption of the ESLs.
For example:
• Increasing the poll interval lowers the power consumption
• Turning off the base stations increases the power consumption
• A lower operating temperature increases the power consumption
• More display updates per day increase the power consumption

8.1 Protocol
Modified 802.15.4 (Physical layer and Media Access Control layer).
8.1.1 The physical layer
The physical layer (PHY) provides the data transmission service, as well as the interface to the
physical layer management entity, which offers access to every layer management function and
maintains a database of information on related personal area networks. Thus, the PHY
manages the physical RF transceiver and performs channel selection and energy and signal
management functions. It operates on the above mentioned frequency band. The PHY layer is
100% compliant and is based on direct sequence spread spectrum (DSSS) technique with a
transfer rate of 250 kbit/s.
8.1.2 The medium access control layer
The medium access control (MAC) layer enables the transmission of MAC frames through the
use of the physical channel. Besides the data service, it offers a management interface and
itself manages access to the physical channel. It also controls frame validation, guarantees time
slots and handles node associations. Finally, it offers hook points for secure services. The EE-
202 does not make use of the optional network beaconing, instead it used a polling mechanism
to increase power efficiency. Some changes are made to the standard to allow for more
efficient data frames and better power efficiency, especially when nodes are not connected to a
base station.
8.2 Security
By default only the image transmission is encrypted using a proprietary encryption protocol.
Enhanced encryption/authentication can be requested on demand by loading different firmware
on the ESLs in combination with the loading of an encryption key and an additional ESL server
module. The protection method for RF-communication is done by 128-bit AES encryption.
