2. 1. Why do we need to learn about smart city?
Because the city that we are living in has many problems:
- transportation
- energy and resources
- environmental pollution
- waste management
2

3. 1. Imagine a city like this
Where we don’t need
to worry about:
- traffic jam
- blackout
- air & water quality

7. 3. Case: Lunch break
- You have just 1 hour for lunch break
- You want to eat ramen for lunch
- Your budget is 1500 ￥
- Nearest and available ramen shop
- Fastest route based on real time traffic monitoring
- Orders ready by the time you reach the restaurant

8. 4. How does Smart City contribute to people?
Smart City gives people many benefits.
The biggest benefit is improving efficiency.
Efficiency creates more time and
reduces cost.

9. 4. Efficiency improvement
Transportation
-Optimization of transportation method,
waiting time, and more.
Energy
-Power saving, efficient power generation,
renewable energy.
Communication
-Speed up, connection by IoT.

10. 5. Current research for Smart City
Many countries and famous companies are
focusing on research on smart city.
Qualcomm :
American multinational semiconductor and
telecommunications equipment company
Qualcomm is progressing development
mainly in the field of IoT.
10
Among them...

11. 5. LTE IoT SDK
LTE Iot SDK is a new software development kit
for LTE compatible IoT provided by Qualcomm.
This tool supports OEMs, developers,
IoT companies to develop new IoT products.
This new wireless technology may cause
changes in every wireless device.

13. 6. Summarizing for movie
● Smart City is the concept of being able to
combine a lot different franchises into a
single unit.
● This system is like a circular system which
eventually makes the whole system even
more efficient, effective and sustainable.
● It makes intelligent connectivity by
combining with human behaviour.
