Question 1

3 principle technical drivers

Answer 1

Scaling of feature sizes

new devices/material

increasing chip area

Question 2

What can sensors measure and how did their cost decrease in the last 10 years?

Answer 2

Decreased 100-fold.

Can measure e.g.:

Leaks/levels

Motion / velocity

Temperature

Humidity

Chemical/gas

Flow

Force/load/pressure/torque

acceleration / tilt

Question 3

What are the main components of 5G Communication

Answer 3

Massive resilience (error rates of 1*10^-5)

Massive control (response 1-10 ms)

massive content (speed > 10 gb/s)

massive IoT (10 years from AAA battery)

Question 4

What was 4G enabled and what will be 5G-enabled? Name 3 examples each.

Answer 4

4G enabled moving content:
Video Call
Video Streaming

VR
Real-time gaming
remote control

Question 5

Components of the Internet of Things

Answer 5

Instrumented: We now have the ability to measure, sense and see the exact condition of practically everything

Interconnected: People, systems and objects can communicate and interact with each other in entirely new ways

Intelligent: We can respond to changes quickly and accurately, and get better results by predicting and optimizing for future events
