Municipal Smart City Communications | ABB Tropos
Solution Overview
Smart city
−− Street lighting systems can centrally monitor and control (on/
off, dim) street lights, reducing energy usage and providing
operational efficiency.
−− Mass transit requires persistent communications with vehicles
at stations and in motion to monitor critical data and video.
−− Mobile workers can have secure wireless access, reducing
operational costs by eliminating monthly cellular card expenses.
−− Transportation departments can replace expensive, low
capacity leased lines used for traffic controllers, variable
message signs, etc., reducing operational costs.
−− Utility modernization reduces downtime, increases reliability.
−− Video surveillance cameras can be monitored centrally,
enhancing public safety and providing video evidence.
−− Public safety can access to critical information from anywhere
around town, improving efficiency and safety.
−− Public Internet access can promote local businesses and
events increasing awareness and local commerce.
Tropos Technology Differentiators
−− Performance – multi-megabit capacity, low latency
−− Security – firewall, IPsec VPN, AES encryption in every router
−− Reliability – rugge equipment; patented mesh routing algorithms
use multiple paths, channels and frequency bands
−− Scalability – can be economically deployed to cover areas as
small as a city block or as large as an entire city
−− Mobility – seamless roaming across entire coverage area
−− Radios – maximum power, best receive sensitivity, outdoor
−− Management – most comprehensive centralized configuration,
analysis and reporting
Increasingly municipalities are looking to smart city
applications as a way to reduce operating costs while
increasing efficiencies and quality of services they provide to
the community. A single wireless broadband network that
supports many applications across multiple municipal
departments – public safety, transportation, utilities, building
inspectors, parks and recreation, parking enforcement, animal
control, etc., can deliver a high value to the community. A
Tropos wireless IP broadband network can provide mobile
workers with access to the Internet and other applications in
the field. The same wireless network infrastructure can be
used for remote monitoring and/or control of devices such as
SCADA, street lights, utility meter reading, distribution
automation, traffic/security video cameras, and more.
Increases Municipal Services and Improves Quality of Life
Wireless broadband networks are flexible and can be deployed
effectively in specific areas such as in city centers or near sporting
arenas, or provide coverage across entire communities. Depending
upon applications, performance, and coverage requirements, a
sparse network can be deployed initially and later densified as
more demands are placed upon the network allowing smart cities
to spread their capital outlay for additional nodes over time. Typical
mounting locations for Tropos routers include city owned assets
such as traffic signals and utility poles where there is ready access
to power.
A Tropos private wireless IP broadband mesh network offers a
reliable and secure communications foundation needed to support
Public safety (police, fire and EMS personnel) – easy, immediate
access to critical information (GPS, building schematics, HAZMAT
databases, medical records, etc.) that is up-to-date while in transit
or anywhere around time. In addition, ad hoc networks for
emergencies can be quickly setup enabling communications
among multiple agencies.
Multi-use Networks for Smart Cities
A Tropos wireless broadband network provides a scalable and
reliable foundation to securely support multiple concurrent
applications for creating smart cities including:
Public Internet access – a valued amenity for the community
around town that enables the public to easily access email and the
Internet without having to find a local hot spot. It can also deliver
public service information such as local events, bus schedules, as
well as increase commerce with advertisements for local
Street lighting systems – the ability to centrally monitor and
manage street lights can significantly reduce energy consumption
and provide significant savings. Examples include dimming of
lights during low traffic times; and resetting on/off times for different
seasons of the year. Planning and centralized management of the
lights can result in longer bulb life and real-time fault detection
replaces manual drive-by detection, reducing costs.
Mass transit – passenger information systems in stations and on
board trains can provide riders with up-to-date information about
train schedules, weather, and events; transit vehicles can leverage
the network to communicate with other operators, mass transit
personnel, and the control center both while the vehicle is
stationary and when it is moving at high rates of speed; on board
video security cameras can be centrally monitored; and stationary
video cameras at stations for security monitoring. A Tropos
wireless network can even deliver reliable access transit systemwide including in places such as tunnels and remote mountainous
areas which are challenging for wireless communications.
Mobile workforce automation – workers have secure access to the
intranet and Internet, extending office applications into the field
including access to up-to-date information (GPS, maps,
databases, etc.); the ability to create and submit information from
the field (work orders, reports, email, etc.); video camera feeds (live
and recorded) can be accessed in the field. Examples of municipal
employees that can use the network include building inspectors,
animal control officers, parks and recreation workers, maintenance
crews, restaurant and health inspectors, parking enforcement
officers, transit workers, and many more. Keep workers in the field
increases efficiencies and productivity, reducing unnecessary trips
to the office and increasing worker safety.
Intelligent transportation systems – traffic signal management,
transit signal priority, variable message signs and cameras (red light
enforcement, traffic monitoring). With Tropos a single network has
the capacity to support all of these applications and more and
replace use of costly, low capacity leased lines.
Municipal utility (water/gas/electric) – remote monitoring and
control of field devices across a smart grid – distribution
automation, advanced metering infrastructure and SCADA; mobile
utility workforce applications. Utility modernization applications can
increase operational efficiencies, billing accuracy, resource
conservation, safety, and quality of service.
Video surveillance – video cameras can be monitored centrally or
accessed by officers in the field in real time providing them with
insights before arriving on site; serving as a crime deterrent and
irrefutable court evidence.
Smart City Network Building Blocks
Tropos wireless mesh routers easily mount to city-owned assets
such as on fixed towers, street lights, utility poles, sides of
buildings, in vehicles, and more. Routers can be powered via an
array of options – AC, DC, PoE, and solar providing connectivity for
mobile municipal workers as well as for remote control and
monitoring of sensors and devices: utility meters, street lights,
video cameras, etc.
The Tropos mesh network securely and reliably connects people,
machines and devices across the city to each department’s IP
network. Tropos gateways can connect to the city’s network via
copper, fiber optic, or PTP/PTMP links. Mobile mesh routers can
be mounted into vehicles – public safety, utility, animal control, etc.
and become an integral part of the network providing broadband
connectivity for one or many devices.
“Seventy-five percent of our city staff perform duties outside
an office. So this network is an important productivity tool for
our employees. And the enhanced communications mean
improved safety and service for our residents, and reduced
costs for the city.”
