Question 1

What are the three cornerstones

Answer 1

1. Enhanced mobile broadband
2. Ultra reliable and low latency communications
3. Massive Machine Type Communications

Question 2

Name some 5G capabilities

Answer 2

1. 50 Mbps everywhere
2. Support dynamic increase of capacity on the fly
3. IoT

Question 3

Name the key step changes in functionality and technical objectives

Answer 3

1. 1/5X in end-to-end latency reaching delays <= 5 ms
2. 1/1000 X in service deployment time reaching a complete deployment in <= 90 minutes
3. Service reliability >= 99.999% for specific mission critical services.

Question 4

If 4G is purposed mainly for video, what is 5G purposed for?

Answer 4

1. Inertnet of Everything
2. TACTILE internet
3. mission critical

Question 5

Explain M2M communication

Question 6

What is the problem with enabling developors to create apps that use the network as a passive bit pipe.

Answer 6

1. The network is treated as a standardized, generic pathway for data with little room for tailoring its its functionality to the specific needs of individual applications or services

Instead of putting all the applications into one pipe, we should have tailored network services.

Question 7

What do factories need?

Answer 7

Time-critical process control in:

1. Positioning accuracy
2. Reliability
3. Density
4. Latency
5. Mobility speed

Question 8

What do automotive need?

Answer 8

Everything except data rate

Question 9

What does energy mostly need

Answer 9

1. Grid access in coverage and density
2. Grid backbone in low latency and reliability

Question 10

What tools enable architects to build systems and a greater degree of abstraction

Answer 10

1. Cloud tech
2. SDN
3. NFV

Question 11

What is network slciing

Answer 11

1. defined by a number of customisable software-defined functions
2. shared by multiple different user-types
3. architecure is tailored to use=type needs
4. resources allocated in a granular fashion

• instead of one pipeline, the network is sliced to suit different use-types

Question 12

What is the advantage of network function virtualisation

Answer 12

NFV allows a network function to be implemented programmatically instead of by a physical piece of hardware.

Has flexibility to execute network functions independently of location

Question 13

What is the advantage of network slicing in terms of billing?

Answer 13

Capability to deliver a wide range of connectivity services to any industry BUT

ensure that usage can be billed accordingly.

Question 14

Which one among the following requirements is
most important for the massive machine type
communication systems?

❑ Very high throughput per connection
❑ Very low latency
❑ Very high connection density

Answer 14

Very high connection density

Definition:

Refers to the number of devices of nodes that are connected to a network, or it can refer to the number of links or communication channels between these devices.
