Product Name : EE-153R

Abstract

This manual provides specifications for the EE-153R Electronic Shelf Label (hereafter referred to as “ESL”).

Overview

The EE-153R is an electronic shelf label with a black/white/red e-paper display and 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.

Electrical Specifications

Electrical Characteristics

Conditions: Operating voltage 3.0V unless otherwise specified

The ESL is in sleep mode almost the entire time. It only wakes up at regular intervals (called the poll time) and then it transmits a poll, which is essentially a request for data, to the base station.
When the base station has no data to send it will acknowledge 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 interval will decrease the power consumption but will increase the response time.
Even though the minimum poll rate is configurable, the actual poll rate is dynamically increased if necessary. A base station can handle the polls from 25 ESL’s per second, so if you have e.g. 1000 ESL’s, the minimum poll rate will be increased to 40 seconds.

Battery

The power is supplied to the ESL by 1 CR2450 battery:

• Nominal capacity: 600 mAh
• Nominal voltage: 3.0 V.
• Maximum self-discharge rate: <1% per year
• Battery life: 4 years minimum (Update frequency: 4 times per day, poll time 20 seconds). A more detailed set of conditions is listed in the table below.

The battery life is made up of several factors. During transmission e.g., the current consumption is much higher than when the ESL is sleeping. The table below shows the various factors that make up the entire current consumption, plus the conditions under which the lifetime calculation was done.

Retransmissions: 10%

Report ratio: 1 to 39

| 61%
Display updates| 4 updates per day

Temperature: 15~25° C

Number of channels: 5

| No

No

| 4%
Sleep time| 99,9%| Yes| 9%
Battery self-discharge| 1 % / year| No| 6%

• The correlation shows whether increasing the listed value under ‘Conditions’ increases (Yes) or decreases (No) the battery life of the EE-153R.
  ** The influence shows the percentage of the specified factor on the entire current consumption.

For example:

• Increasing the poll interval improves the battery life
• Turning off the base stations shortens the battery life.
• A lower operating temperature (below 15° C) shortens the battery life.
• More display updates per day shortens the battery life.

Protocol

Modified 802.15.4 (Physical layer and Media Access Control layer).

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.

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 EE153R does not make use of the optional network beaconing, instead it uses 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.

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.

Labeling

Product Label

The product label is affixed to the ESL as shown below

Label material:
Material: Base + laminate protection against wear.
Base: PP film, thickness 80µm, backing with glue.
Laminate: PET film, clear, thickness 25µm.
RoHS compliant

Label dimension:
19 x 36 mm (hx w)
Tolerance ± 0.1mm
Corner radius 1mm

Barcode area:
The size of the barcode area (without the human readable part) is 2.6 x 27.9mm.
The barcode shows the product serial number. This is a ‘B’ followed by 7 hexadecimal digits.
This serial number is the same as the MAC address in the ESL-label, with the first 9 digits (‘3889DC000’) replaced by a ‘B’.

Shipment Box Labels
The shipment box labels are meant to show the regulatory information on the shipment box as well as the quantity in the box. The labels are 105mm*160mm and are made from plain paper with adhesive backing.

This is the standard Opticon shipping label, design rev2 and the various variable fields in the above drawing are indicative only.

Packaging Specifications

Individual Packaging Specification
The ESL’s do not need to be pac ed separately. To easily pac them, 30 need to be packed in a plastic moulded tray. After packing, two silica gel bags are taped underneath the tray and then the tray is sealed in a plastic bag.

Collective Packaging Specification
