Open Communication
Standards
The 7 OSI Layers
The Open Systems Interconnection
(OSI) Model was developed by
International Organization for
Standardization (ISO) in the 1980s as
an attempt to make communication
between any two systems possible.
Before this, every equipment
manufacturer implemented its own
set of rules (protocols). Therefore, two
computers made by different
companies could not "understand"
each other.

Open Systems Interconnection History
• Defined by Hubert Zimmerman in 1978Consistent model of protocol layersDefined interoperability between network devices and software
• Refined and Published by ISO in 1984
• Considered too complicated, inefficient and un-implementable
• Eventually replaced by the Internet’s TCP/IP protocol

Where Does ZigBee Fit?
ZigBee – A Growing Standard!
“Low power wireless sensing and control markets, enabled by ZigBee, are
experiencing exponential growth. Today, ZigBee chipset suppliers
are shipping tens
of millions of units and the market is poised to grow to hundreds of millions of
units within the next few years. Our research with more than 600
companies has
found that the ZigBee market has "crossed the chasm" and is now a mainstream
technology. Despite a challenging economy, 802.15.4/ZigBee unit sales have
increased an average of 62% per year since 2007. Moreover, chipsets using ZigBee
specifications made up 75% of the 802.15.4 shipped units in 2009.”

The Considerations for an Open Standard
Zigbee – some background
•Created for applications such as Home Area Networks (HAN) that
are suited for low power consumption and short distances
•In order to meet the needs of a Wide Area Network such as street
lighting, the power has to be greatly increased and the number of
potential nodes increased.
•Most “modified”
Zigbee products will not interact with other
Zigbee products
Zigbee
•Increased Zigbee coverage means increased latency
•Bands: 868 MHz (Europe), 915 MHz (US), 2.4 GHz (International –
Most Common)
•At the PHY layer, a 915 MHz device cannot communicate with a 2.4
GHz device
The “World‐Wide”
2.4 GHz ISM Band
•2.4 GHz Pros– International – Can use in most countries
– Large bandwidth, allows numerous channels
– 100% duty cycle is possible– More compact antenna than 915 MHz
•2.4 GHz Cons– Shorter range (poorer propagation) than 915 MHz band
with same power
– Must share with WiFi, Bluetooth, Cordless Phones,
Wireless Game Pads, Toys, Wireless Audio Devices, PC
Peripherals, and Microwave Ovens
Mesh versus Star Network
•New mesh node must be “built”
from Gateway outward
•New star node can be placed anywhere in cell coverage area•Zigbee distance limited to several hundred feet
•UNB distance several miles
UNB Technology(Ultra Narrow Band)
A proprietary communication system
•Range of 2‐5 miles (Zigbee range measured in feet)
•One Base Station (Gateway, collector) can handle up to 10,000 street lights,
thus minimizing the number of backhauls (minimizing monthly telecom bills)
•Measurements include ambient light levels and temperatures
•Aux controls can include traffic flow and other considerations•Street light controls (endpoints) can be randomly installed throughout the
coverage area, greatly simplifying new system commissioning
•Direct connection between each Base Station and endpoint, reducing system
latency
Commissioning a System•Commissioning Plan
– RF Mapping Plan for Network Planning• Important to plan the optimum number and positions for the Base
Stations (Gateways) to achieve proper radio coverage. Radio
planning tools should be used that make use of geographic terrain
and clutter data and radio propagation models.
• The radio model / map is then used in conjunction with a site
survey with local authorities and contractor staff to confirm Base
Station sites and document installation details.

• Asset list and information
• Commissioning Training – Before starting
installations!
• Dimming profiles for each type fixture (response to
0‐10 v dimming signal is not typically linear)
• Operational Training – make sure user’s
expectations are realistic
• Make it clear that little effort into system = poor
results from system
Commissioning
The endpoints (nodes)of a mesh network mustbe installed starting close to the coordinatorin order to maintain the mesh.
The endpoints of a star network can be installed randomly throughout the coverage area.
Dimming•Different types of dimming controls:
– 0‐10 VDC• Currently most common in the US
• Simple
• Only one way communication–
cannot send information
from the ballast/driver back through the system
– DALI (Dimmable Addressable Lighting Interface)
• Becoming increasingly used in Europe
• Offer two way communication – able to read information
from the ballast/driver back through the system
• DALI was designed for interior lighting…
commands not ideal
for street lighting

Dimming Profile
Street Light Metering(More questions than answers!)
•Who owns the meter?
•What is the accuracy of the meter and how is proper calibration
maintained?
•Is the utility to have an audit program?
•Who maintains the data and how is security maintained?
•Are the data to be presented to the utility as a list of individual street lights or in the aggregate?
•What accuracy does the industry need? (What accuracy do we
have now? Consider the statistical aggregation compensating for
the individual accuracy variation.)
Factors Affecting Meter Accuracy
• Temperature
• Range (voltage, current, power)• Power Factor• Frequency• Calibration• Cost

• Pedestrian Traffic Volumes
