1. IntroductionZigBee Retail Services helps retailers reinvent the
shopping experience for a customer-centric process by
ayering new control capabilities into everyday tasks.
With this innovative technology, ZigBee Retail Services
enables retailers to increase productivity, strengthen
customer loyalty and streamline operations with theunderpinnings of a comprehensive data-driven
nfrastructure tailored to the retail environment. The
underlying mesh network infrastructure provided by
ZigBee is ideal for implementing the retail service
components of a system that enhances the shoppers
experience and brings greater efficiencies to retailers.
Standardized retail services solutions enable retailers
to build networks incrementally and cost-effectively
with components, and to scale by adding additional
devices with specific functions without expanding the
network infrastructure or integrating new software
nto the retail systems back-end servers.
Figure 1: Holistic approach to the retail ecosystem
The ZigBee Alliance-defined components automate
the retail environment to enhance shoppers
experience, such as: More consumer control Help in remembering what to buy
Locating products easily
Determining the price of an item
Finding help easily when needed
Reduced wait time to pay and bag items
The components bring efficiencies to the retailer
through: Data collection
Shelf item management
Inventory management
Asset management
Physical plant management
Personnel management Risk abatement
Reduced shrinkage and spoilage
In order to facilitate shoppers active participation an
retailer efficiencies, we envision enabling many of th
key components of the retail space with ZigBee
systems, creating a holistic wireless network that
includes the shoppers themselves, Intelligent
Shopping Carts, and shelf tags.
2. Defining a New Customer ShoppingExperience
Imagine a customer arriving at a store with a portab
electronic Personal Shopping Assistant. As the
customer approaches the store, the handheld device
communicates with and then joins the stores holisti
retail network. When the shopper chooses an
Intelligent Shopping Cart that is already part of the
stores network, the Personal Shopping Assistant
creates a relationship with the cart that the networkunderstands and, more specifically, the back-office
retail server understands.
At the same time, the networks location engine star
a trace of the Personal Shopping Assistant and the
Intelligent Shopping Cart that records the shoppers
movements through the store and the parking lot.
If the shopper uploads a shopping list prior to arrivin
the retail server communicates the best way to
navigate the store using the shopping list.
Furthermore, the retail server also informs the shopp
about special offers or other promotional events suc
as coupons related to the shopping list. If the Person
Shopping Assistant indicates the need for a
prescription, the network triggers an order for the in
store pharmacy and adds the directions to the picku
window to the customers shopping path. Should th
customer need help, store personnel can get to the

customer quickly assisted by the location engine.
Finally, the customer is able to breeze through
checkout as the items in the cart have already
been scanned.
FIgure 2: Customer or Cart Interactions
The ZigBee Retail Services standard defines the
messages being exchanged between the Personal
Shopping Assistants, the carts and the retail server. The
ZigBee PRO specification, the base networking system,
handles the joining and authentication process, whichs guided by notes in the ZigBee Retail Services
standard. With messaging, the retail tunnel cluster
covers the specific application messages between the
Personal Shopping Assistant and the retail server, and
the ZigBee Telecom Services location cluster covers
ocation services. All are standard ZigBee messages.
As the customer shops, scanned items and Personal
Shopping Assistant information are communicated to
he retail server through retail tunnel messages. As theback office receives UPC messages from the customers
Personal Shopping Assistant, it compares the weight
change reported by the load cell in the Intelligent
Shopping Cart with the known weight of the item
hrough its UPC code. If the weights match, the item is
accepted and a text message or another feedback
mechanism displays on the Personal Shopping
Assistant. However, if there is a discrepancy, the
customer receives an alert on the mismatch and
instructions on how to correct the discrepancy. The
system tracks if a particular customer is having troub
by registering a high number of discrepancies and it
dispatches a retail associate to help based on locatio
information from the shoppers handheld device.
As the customer continues to shop, the retail server
builds the invoice for the cart, as well as other logisti
data about the customers path through the store.
The system recognizes that the customer is ready to
leave when the customer enters a checkout area. Th
retail server transmits the invoice through the retail
enterprise network to a POS system that enables the
customer to complete the transaction.
The customer can then leave the store with the item
When the Personal Shopping Assistant leaves the
holistic retail network, the relationship between the
cart and the Personal Shopping Assistant is severed.
In the scenario described above, much of the
complexity of the mobility of the Personal Shopping
Assistant and the cart is hidden from the customer. F
example, in cellular networks, mobile devices that ar
end nodes move about and need to migrate from
router to router or access point to access pointdepending on the specific network implementation
This mobility causes the mobile devices to roam
various access points as they move, and this, in turn,
causes the holistic retail networks routing tables to b
in continual flux. ZigBee in general, and the ZigBee
Retail Services and ZigBee Telecom Services in
particular, are designed to handle complexity of this
mobility, making it possible to have mobility and
efficient network use in the same dynamic
environment.
This use provides customers with an in-store
experience that enables them to shop at their own
pace, check prices easily, view their running financia
total as they shop, locate products, scan and bag
products their way, and minimizes the touching of
items by others, pay for goods with minimal store
associate interaction and experience minimal audit

processes. In addition, it allows for payment with
minimal associate interaction, and minimizes audit
processes. This experience carries over to at-home
shopping uses that enable the creation of shopping
ists, price comparisons, and coupon offers. It also
reduces out-of-stock situations when customers
arrive at the retailer. Additional services could
nclude support for pharmacy services or allergy
alerts. What this really boils down to is an experience
where the customers have complete control of their
shopping experience, at their own pace with
opportunities, gently aided by the technology, to
save time and/or money.
3. ZigBee Retail Services DevicesThe core ZigBee Retail Services devices envisioned in
the system includes:
Personal Shopping Assistant: Customer devices
with a bar code scanner to read Universal Product
Code (UPC) labels on products, a two-way
communication display, a keypad, audio
components, and more.
Intelligent Shopping Cart: Standard shopping
carts equipped with a load cell designed to sense
weight similar to self-checkout kiosks used at
grocery stores today.
Fixed Access Points: The process of one device
connecting to another device in the holistic retail
network including the retailers back office and a
gateway device sitting between the stores holistic
retail network and back office.
Figure 3 provides a system-level diagram of the typical
nfrastructure.
Figure 3: System-level diagram of a Retail Services implementation.
Other ZigBee Retail Services devices include: Employee Customer Concierge: A device similar to
the Personal Shopping Assistant with added
management capabilities to help locate and assist
customers, re-stock shelves and complete
personal shopping tasks.
Electronic Shelf Labels: Digital displays with price
and product information. Asset Tracking Tags: Devices applied to pallets,
forklifts, hand carts, ladders, maintenance and
cleaning equipment, and other high-value assets
which enable decision-making based on historica
location data.
Electronic Shelf Edges: Larger multi-media display
devices showing advertising, product information
movies and more.
Other Components from ZigBee Standards:
Components such as ZigBee Building
Automation for environmental control, ZigBeeHealth Care for pharmacy/clinic operations,
ZigBee Light Link for lighting control, ZigBee
Remote Control for display device controls, or
ZigBee Smart Energy for energy management.
The ZigBee Retail Services network also extends in
the shoppers home, enabling the shoppers
handheld Personal Shopping Assistant or ZigBee-
equipped smartphone to interact with the retailer
enterprise network through an in-home gatewaydevice. This would enable the customer to take
control of their shopping experience even before
they have left their home.
4. Key Use CasesA number of routine activities benefit from increased
connectivity and control. Below are several key areas
addressed by ZigBee Retail Services.
1) Advanced Shopping: The use of ZigBee handheld
devices and shopping carts lets stores personalize
and customize each shoppers experience.
Shoppers scan items just once using a Personal
Shopping Assistant before placing them in the
Intelligent Shopping Cart. Personal Shopping
Assistants connect to the holistic retail network
seamlessly and communicates the UPC
information of each item and the incremental
weight change in the cart to a back-end server. It
ZigBee Retail Services Delivering Next Generation Shopping Experience October

is then verified and added to the ongoing list of
items the shopper has collected and may trigger
customized purchase recommendations, sales or
special offers. If the incremental weight reported
by the shopping cart correlates with the recorded
weight of the item scanned, the Personal
Shopping Assistant adds it to the shopping list. If,
on the other hand, the weight does not correlatewith the item, the customer receives a message
on the Personal Shopping Assistant directing the
customer to either rescan the item or return it to
the shelf. It would also trigger an alert to the
support staff of the retail facility to assist the
customer if necessary, for instance if the customer
is scanning an item multiple times but the PSA is
not adding it to the shopping list which would
indicate some technical glitch.
The Personal Shopping Assistant can exchange abroad range of information with the retailers
back-end servers and personalize a customers
shopping experience.
For example:
Current shopping and loyalty (if applicable)
information
Daily sales information
Forthcoming sales opportunities
Real-time customer information (e.g, notice
to/from pharmacy such as prescription isordered/ready)
Special retail offers for preferred customers
Help requests to/from Retail Associates, product
location services
n conjunction with the location engine that is part of
he holistic retail network, the Personal Shopping
Assistant updates information on items that the
shopper is approaching based on the shoppers
projected path through the store.
The announcements on the Personal Shopping
Assistant could also be tailored using shopper-specific
profiles that determine the level and variety of
announcements that the shopper wants to receive.
These announcements might be: Product advertisement
Alerts (such as health and ingredient conflicts)
Personalized downloading based on customer
profiles and shopping lists
The Personal Shopping Assistant also provides two-
way voice and text or short messaging service (SMS)
like communication with store personnel.
2) Customer-Centric Personal Shopping Assistant
Used at Multiple Retailers: In some situations, the
customer owns the Personal Shopping Assistant
instead of the retailer. As such, the shopper would
carry the device home as well as to other retail
locations and potentially competitive retailers.
Some scenarios include the use of the Personal
Shopping Assistant in retail mall environments or
at different retailers within the same complex. The
Personal Shopping Assistant becomes an essentia
part of the customer shopping experience as the
shopper moves from store to store.
A variation of this general case is the use of the
Personal Shopping Assistant at multiple locations
of the same retailer, potentially even
internationally. Here, the retailers enterprise
systems allows shoppers information and system
access credentials to be distributed to a specific
store location when shoppers visit with their
Personal Shopping Assistant.
3) Customer Retail At-Home Experience: With a
customer-centric handheld ZigBee device at
home, the customer can build shopping lists or
inquire about product availability using the
Personal Shopping Assistant through a
gateway device that communicates with the
retailers enterprise services over the Internet.
Further, when a customer arrives at a store with
a preloaded shopping list, the Personal
Shopping Assistant guides the customer
through the store using the most efficient path
This eliminates the need to walk up and down
aisles looking for specific items or looking for
help finding specific items.
4) Asset Tracking and Customer Behavior: The
shoppers Personal Shopping Assistant and
Intelligent Shopping Cart are tracked thereby
gathering critical shopping behavior data and
tracking of store assets. Retailers gain insight
ZigBee Retail Services Delivering Next Generation Shopping Experience October

into how and where customers move through
the retail floor space, how long they pause at a
specific location, locations where they do not
shop and how quickly or slowly they travel
through specific areas. This data provides
feedback into how well areas of the retail floor
plan are performing and how and where to
improve merchandising and increasemarketing opportunities. In an emergency,
specific tracking data helps to locate customers
in distress. Alternately, using this same location
feature for the Intelligent Shopping Cart, it
provides asset tracking of the cart itself or
other items in the store that are mobile and in
jeopardy of being removed.
5) Personnel/Inventory Tracking: As with the
Personal Shopping Assistant, retail associates use
an enhanced version of the device to track itemson the shelf for stocking or re-stocking. With the
device location feature, management monitors
associates effectiveness at specific tasks using
real-time interaction with the retail back-end
server to provide detailed task management and
reporting.
6) Electronic Shelf Labels and Shelf Edges: Shelf
labels, the electronic versions of price tags,
product information, and sales information seen
on the retail shelf today, allows for two-wayradio contact with the retailers back office. The
primary goal is to enable the retailer to update
pricing and other critical information displayed
on the shelf tags in real time and at the push of
a button. More advanced scenarios have the
shelf tags interacting with the back-end server
location engines to personalize shelf tags when
customers approach the item in question. A use
case for this is to flash the display on the tag
when an approaching shopper has that item on
the handheld shopping list, thereby drawing
attention to the items location.
7) ZigBee is ideal to accomplish the sensing and
communications processes required for tasks
associated with supply chain management.
Managing this side of the retail equation improves
the way a company finds the raw materials it
needs to make a product or service and deliver it
to customers. In the context of the retail
environment, it involves:
Obtaining raw materials for production of
marketable goods
Asset tracking (e.g., people, forklifts, hand
trucks, pallets, tractor trailers, special materials)
Just-in-time inventory
Virtual demand and predictive inventory Cold chain management
Delivery loading/unloading
Warehousing/location of raw materials and
products
Monitoring temperatures, humidity, unusual
motion, salinity, spills, etc.
Monitoring sort systems in warehouses
Monitoring activities for safety and security
(e.g, video)
Maintain telematics information for trucks and
other vehicles Return/exchange strategy
These factors are the critical elements of
successful supply chain management. As an
example, ZigBee technology is already being used
for monitoring the integrity of refrigeration in
truck fleets transporting perishables. Wireless
sensors deployed in pallets to monitor that the
correct temperature is maintained from origin to
destination can be mesh networked using ZigBee
and the information can be sent regularly to thecentral servers. Since ZigBee technology is ultra-
low power it is well suited even for long distance
transportation. When the trucks reach their
destination the monitoring data for the trip can be
sent to the systems in the receiving facility and
any pallet that was not maintained at the right
temperature through the trip can be easily
identified and not offloaded at all. This proactive
ability to identify refrigeration failures can help
minimize spoilage, avoidable paperwork like
insurance claims etc. The same network can also
be leveraged to identify spillage en route. This can
have a huge impact on businesses in reducing
operating costs and quality issues.
8) Other ZigBee standards, including ZigBee Building
Automation, ZigBee Health Care, ZigBee Smart
Energy and ZigBee Light Link, specifically relate
to retail operations, safety and security. These inclue

Food Safety Management to report storage
temperatures, humidity conditions in coolers,
meat lockers and more.
Temperature alerts for other appropriate areas
as required (such as meats or dairy)
HVAC systems monitoring
Open/close restricted entrances, windows, etc.
monitoring Health hazards/high-risk areas monitoring
Safety alerts (for fire, flooding, earthquakes, etc.)
Shelf-stocking issue monitoring
The efficient operation of lighting systems, control
of temperatures and preventive maintenance can
represent significant savings for any retailer. For
larger retail chains that can include thousands of
stores and other facilities, it can result in
substantial savings. Large retailing leaders such as
Kroger are very committed to supporting food atsafe temperatures, which entails very accurate and
reliable monitoring of coolers, produce, meat and
other perishables. This has an impact on safety for
consumers and also the lifespan of products. For
example, strawberries should last four to five days
after purchase but if they have been exposed to
higher temperatures, they will not last that long.
Not only does ZigBee technology enable retailers
to keep out of specification products from being
sold to customers, but also assists in preventive
maintenance of devices reducing spoilage andenergy wastage. Energy savings can translate into
big dollars and in fact, studies have shown that
the energy saved is equivalent to one years
payback of infrastructure cost.
Linking the monitoring and control of the physical
plant to other aspects found in the ZigBee Retail
Services standard such as personnel tracking, can
yield further benefits in terms of safety, reporting,
and risk mitigation.
A prototypical system diagram displays below.
FIgure 4: General System Diagram
5. Location engineA key component of ZigBee Retail Services is the
location engine, a system which tracks the location o
all radio-enabled elements, or more typically, trackinthe location of the mobile elements, the Personal
Shopping Assistant and the Intelligent Shopping Ca
The devices which require location tracking can use
the Location Cluster from the ZigBee Cluster Library.
This cluster provides a means for exchanging Receiv
Signal Strength Indication (RSSI) information among
one-hop devices as well as messages to report RSSI
data to a centralized device that collects all the RSSI
data in the network.

The example below displays the usage of the RSSI
ocation cluster:
Figure 5: Location Engine
This mechanism forms the basis for all the tracking
mechanisms in the ZigBee Retail Services standard
from customer tracking through asset tracking and has
a significant impact on the quality of service being
delivered by the retailers.
6. The Better SolutionAdvanced retail services are ideally suited for ZigBee
wireless technology versus 802.11 (wireless
technology) because retail mobile devices require low
cost, long battery life, high security (encrypted data)
and maximum location accuracy.
Most ZigBee devices are typically in sleep mode
until they need to communicate data. Compare
this to always-powered-on 802.11 devices that
must be mains powered or require repeated
charging during the course of the day.
ZigBee uses radio technologies with blocking
features specifically designed to reduce
unwanted radio signals. This allows ZigBee
devices to get their messages through on the
first try. Repeated retransmissions reduce total
battery life and add latency into devices
receiving information. By contrast, 802.11
devices are naturally very chatty. These frequent
and unnecessary message status transmissions
reduce battery life.
ZigBee devices operate on a secure network
allowing devices to enter and exit the network.
Each one of these ZigBee devices only operates
with another secure device in the network.
ZigBee networks use robust mesh technology
with built in redundancies and no single point ofailure, versus a star network used by 802.11.
ZigBee routing devices pass data, allowing a
small number of devices to achieve greater total
range than any 802.11 network. 802.11 devices
use a star network, requiring the receiving
device be within range of the transmitting
device with potential for points of failure.
7. Payment ScenarioWhen the customer reaches a Point-of-Sales (POS)
station, an invoice for the items scanned and added
the Intelligent Shopping Cart is presented
automatically to the shopper with payment options.
The retail systems back end communicates the
information for the invoice to the POS system. The
location engine in both the customers Personal
Shopping Assistant and the Intelligent Shopping Ca
triggers the checkout process as the shopper enters
the checkout area. With the handoff completed, the
POS system, which is not specifically part of the reta
services profile but still an essential part of the overasystem, takes over, enabling the shopper to speedily
pay for the items and exit the store.

8. Retail Employee Use CaseThe retail-employee use case is similar to the
customer handheld case. The two devices are very
similar, and often, the same device. The usage
scenarios differ from the customers use. In particular,
the retail employee uses the device, at a minimum,
to track the location of the Retail Associate over timeto allow for labor tracking. The UPC scanner in the
device is used for shelf-level inventory control, a
scenario that is the opposite of the customer
shopping experience; the item is registered as added
to the shelf rather than removed. The item scans
provide the back-end servers with the information
needed to manage shelf-level inventory. The
Employee Customer Concierge device is used for
UPC scanning and still images, shelf-level inventory
control, capturing photos for security, compliance,
and task completion audits. Through the devices
display and potential two-way audio components,
management can communicate directly with the
retail associate to provide updates or revised work.
9. Electronic Shelf Labels and ElectronicShelf Edges
Future releases of ZigBee Retail Services are expected
to address the use of electronic shelf labels and multi-
media shelf edge devices that would replace the
current shelf tags that display pricing for the items onthe shelf and other item-oriented information. The
electronic shelf tag is a display device that allows the
tem information, such as a description and its price, to
display to the customer and allows updating of this
nformation on tag-by-tag basis through the holistic
retail network.
Other functions the tags might perform are alerting
specific customers to special offers or alerting the
shopper to the shelf location of an item when theshopper is in the area. This can help the retailer in
accomplishing higher sales per visit by the customer.
Figure 7: Electronic Shelf Label Interactions
10. In-home scenarioThe customer Personal Shopping Assistant is a speci
retail device that is used in multiple networks. The
customer may register with multiple retailers, as welaccess the retail information from locations other tha
the holistic retail network (e.g., from their home,
friends homes, hotspots, hotels, etc.) The most
prominent example is of a consumer connecting the
Personal Shopping Assistant via a gateway at home.
With the device at home, the customer creates
shopping lists and checks item availability or price
prior to visiting the store, either by entering the data
on the device or by scanning an items UPC.

A system level diagram of the in-home case is
diplayed below:
Figure 8: In Home Scenario
11. SecurityThe data generated by ZigBee Retail Services devices
contains confidential information with respect to
health care and mobile payment, money-sensitive
nformation regarding pricing and offers, and other
mportant information regarding the control of
equipment used to store goods and track assets. While
security requirements differ slightly with different
types of data, all of it should be protected from
unauthorized usage with respect to confidentiality,
ntegrity, and authenticity.
Confidentiality: For Consumer Privacy, some of the
information transferred in the network is relevant
for consumer privacy. Thus, confidentiality of the
whole data flow needs to be protected for a
medium timeframe.
Fraud Protection: Some information directly linked
to transactions that have monetary value should
be protected in terms of integrity and
authenticity, and should be capable of standing
up in court. Associates who may try to manipulate
the system in order to manipulate their work
schedule, may also commit fraud.
Protection of Control Networks: The network
sends control information to both devices and
associates. This information should be

Retail Services allows devices to either rely on netwo
level security alone, or add application level security
applications with higher security requirements.
Devices under the control of the device owner (e.g.,
devices taken home by the customers) are especially
vulnerable to attacks.
Ultimately all ZigBee Retail Services devices support
network-level security (i.e. the network keys shall no
be well known). This network key communicates wit
the devices through a set of encrypted messages to
site-specific Trust Center link key. The Trust Center Lin
keys are under the direct control of retailers.
Using network-level security provides protection
against sniffer devices that are not part of the netwo
while also providing protection from rogue devices
trying to disrupt the network.
The network can provide additional security at the
application layer using application layer link keys
which provide peer-to-peer encryption andauthentication and/or retailer-specific encryption th
can be applied to the retail tunnel payload.
