4. Internet of Things (IoT)
Modern digital networks make all of this possible.
Sensors are everywhere generating massive amounts of data.
◦Smart home/office : motion sensors, light sensors, doorbell sensors,
temperature sensors
◦Smart traffic : sensors in traffic light, transport trucks, parking garages,
security cameras
◦Self-driving cars : ultrasound sensors, cameras, precision GPS

5. Internet of Things (IoT)
Refers to the ever-growing network of physical objects that feature an
network connectivity, and the communication that occurs between
these objects and other network- enabled devices and systems.
Sensors and measuring devices collect and transmit their data
Data can be:
◦Stored and analyzed at a later date
◦Analyzed immediately (machine learning) to be used to perform related
processes

6. Network Types
Personal Area Network (PAN)
◦Personal area networks are small networks where connected wireless
devices are within personal reach LAN

7. Network Types
Local Area Network (LAN)
◦LANs are typically networks in a small or local geographic area, such as a
home, small business or department within a large corporation
◦Can be wired, or wireless
Wide Area Networks (WANs)
◦The term WAN typically refers to a collection of LANs that provides inter-LAN
and Internet connectivity for businesses and governments.

The Cloud
◦It is a collection of data centers or groups of connected servers that are used to store and analyze data, provide access to on-line applications,
and provide backup services for personal and corporate use.

8. Network Types
The Edge
◦The edge refers to the physical “edge” of a corporate network.

Fog Computing
◦Often, there is a need to store the
sensor data securely and closer to
where the data can be analyzed.
◦The pre-processed data can be used
immediately to update or modify
processes within the organization.
◦The fog is located at the edge of a
business or corporate network. The
pre-processed data can then be sent
to the cloud for more in-depth
computing if required.

Decision Making
IoE
Internet of Everything (IoE) brings together people, process, data and
things to make networked connections more relevant and valuable.

11. Assignment
You are required to perform some study about LoRa and present your
findings about it. Your presentation (~10-15 mins) should at least include the
following topics:
1.What is LoRaWAN in IoT?
2.What is the basic specification of LoRa (wireless modulation)? You may
focus on specifications in North America.
3.What is the advantages and limitation of LoRaWAN ?
4.How is LoRaWANcompared to other IoT/WAN/cellular network
technology?
5.Basic network architecture of LoRaWAN
6.Give an application of LoRa in IoT if you would have a chance to build
one.
