3. Introduction
• The choice of this topic is consequent upon the desire of the government
of my country, Nigeria, to turn some of our cities, including our capital –
Abuja – where l reside into a smart city. Smart Cities Nigeria 2017
Conference was held in Abuja from 8th to 9th August, 2017 to provide a
common forum for stakeholders to discuss and make proposals towards
establishing smart city programs and initiatives in Nigeria.
• I believe that Smart Street Lighting can be the platform Nigeria needs to
actualise its smart city dreams. Smart lights can collect and communicate data

4. Introduction ….
relevant to transport, environment, city management, energy, safety and
security. Smart lights can detect traffic congestion and track available parking
spaces. This information can be used to monitor and respond to any
circumstances and also build IoT solutions that will turn Abuja, Lagos and
some select Nigerian cities into smart cities.

5. The Problem
• Major roads and streets within Abuja, our capital, are filled with a large number of
non-functional street lights. The prevalence of darkness on the roads and streets
create avenues for men of the underworld to perpetrate crimes, touting and
intimidation of unsuspecting citizens and also makes the city less receptive and
attractive to residents and visitors.
• Daily Trust (Nigerian Newspaper) of July 17, 2017 reported that over One Billion
Naira ($2,800,000) was spent to power street lights and acquire 22 generating sets to
support lights in Abuja by our government. However the lights do not stay
functional for long due to poor maintenance culture of city officials.

6. The IoT Solution
Street lights consisting of LED light are equipped with brightness
sensor, motion sensor and a short distance communication device.
The motion sensors enable the street lights to detect movement by
pedestrians, cyclists and cars. The communication device enable
them to communicate. When a passer-by is detected by a sensor, it
communicates this to neighbouring street lights which will brighten
so that people are always surrounded by a safe circle of light. The
lights turn on before pedestrians and vehicles come and turn off or
dim when no one is around. The street lights are monitored and
controlled/managed wirelessly from a central operating centre. The
control team can tell exactly which lights requires attention as
warning signals are received when a light defects so that a technician
could be sent to fix it. The sensors connect to a gateway or hub
which has LPWA connection.

7. The Benefits
The IoT solution can deliver a range of
benefits such as: Light up Abuja at night
thereby beautifying and illuminating the city.
Improve security, roadway safety and
commercial activities. Reduce energy
consumption, maintenance costs and high
cost of keeping the city lit. Central
monitoring and reporting for individual
lights enables more effective maintenance.
The data gathered by the Smart Street lights
can be used to provide other IoT solutions
for the City.

8. The Technology
Feature Requirement Comment
Network Area Wide It will be used in a broad range of locations some of which
may not have broadband connection
Spectrum Shared or Dedicated Quality of Service (QoS) is not a crucial factor
Battery Life Long battery life Solar Panels will also be used to extend the battery life
Connectivity Cost Low There is no need to transfer large volumes of data
Module Cost Low This needs to be kept low so that adding the Solution to
existing street light is affordable, ensuring that price is not an
issue.
Bandwidth Low The Solution only requires low bandwidth
Technology LPWA. It could also possibly be built around 2G

9. Business Models
The Business models that could be used to commercialise the Smart Street Lighting service are the following:
Business Models Revenue of the IoT
Company
Device Ownership Comment
Product-as-a-Service Recurring IoT Company Under this model, the IoT Company rents the device
to the local authorities for a fixed periodic fee that
includes the rent of the device, installation,
maintenance, support and connectivity
Performance-as-a-Service Usage User (local authorities) This will tackle our poor maintenance culture. Under
this model, the IoT Company is responsible for the
Smart Street Lighting maintenance and only gets paid
if the lights are functioning.
Transactional Upfront User (local authorities) Here the IoT Company sells the device for a one off
fee and accrue additional revenue by charging for
installation and customer support. Connectivity for
the solution will be charged and paid separately.

10. Risks and Policies
Operational Considerations
• Network Coverage: This will be a key consideration if
2G network is used. There are some areas in Abuja
where network coverage is not very good.
• Interference: If LPWA technology is used, there is a
possibility that interference could affect communications
between the lights and the control centre
• Risk of vandalism: Hoodlums may deliberately
destroy/damage or steal the devices
• People may feel that they are under surveillance. It is
therefore imperative that privacy by design is built into
the Solution
• If the solution is sold with connectivity embedded, the
IoT Company must ensure that the device can work on
our local networks
Policy Solutions
• Protection of consumer privacy and the data collected
• Compliance with existing privacy and security regulations
• Need for regulatory clarity that will support the deployment
of the Solution
• Collaboration/partnership between all levels of government
(stakeholders) in Nigeria to ensure success of the Smart
Lighting Solution
• Clarity in the establishment of responsibility as well as
ownership of the data collected
• Government support in building public trust in the IoT
Solution
