5G Use cases

Question 1

What are use cases attributed to 5G

Answer 1

Enhanced Mobile Broadband, Fixed Wireless Access, Massive Iot

Question 2

Limitations of 5G FWA

Answer 2

1. The tech is designed to provide a point-to-point link from one fixed spot to another. It would not deliver broadband to people on the move, so it does not deliver a full mobile broadband experience

2.It is more susceptible to disruption than fixed lined connections

Question 3

Type of spectrum used for 5G FWA

Answer 3

The best option would be below 6GHz, however due to its limited availability and relatively narrow band, many operators decided to initially deploy 5G FWA in millimetre bands

Question 4

costs of providing FWA vs deploying fixed connections

Answer 4

70% costs reductions and easer to install by user

Question 5

Limits of millimetre spectrum

Answer 5

Limited ability to penetrate buildings and has a reduced range

Question 6

What are the new uses cases of 5G

Answer 6

Massive IOT and Ultra Reliable Low Latency Communication (URLLC)

Question 7

5G Capabilities

Answer 7

1. Massive Connectivity 2. Capacity Enhancement 3. Low Latency

Question 8

Services related to enhanced mobile broadband

Answer 8

Security cameras, transfer gigabytes in a second, 4K 3D video, work and play in the cloud, augmented reality, industrial and vehicular automation, voice calls

Question 9

Services related to low latency

Answer 9

mission critical broadband and self driving cars

Question 10

Services related to massive IoT

Answer 10

sensor network

Question 11

5G specific Iot Technology

Answer 11

5G continues NB-IoT and LTE-M which were already part of 4G tech; it is said that currently the 3GPP doesn’t have the intention to standardise specific IoT tech but may do so in the future for high end Iot applications

Question 12

5G Targets Iot Tech

Answer 12

NB-Iot 15 km coverage / 150 kbps throughput/ 10 year battery life

LTE-M 11 km coverage / 1 mbps throughput / 10 year battery

Question 13

Examples of new 5G uses

Answer 13

logistics (to enhance efficiency of distribution networks), smart transport (to reduce congestion), smart agriculture (to improve crop and yield), smart grid (redes eléctricas inteligentes, to reduce energy consumption), ultra reliable communications

Question 14

4G vs 5G Latency

Answer 14

4G - Less than 50% users are guaranteed with 40 ms or less latency

5G - About 70% users are guaranteed with 40 ms or less latency

Question 15

Impact of 5G Low Latency feature + Massive Iot Capabilities of Iot

Answer 15

it allows mobile networks to support new types of services. New services are targeted at areas such as industrial automation,smart transport, health care and public safety systems

Question 16

What is eMBMS used for in 5G in addition to broadcast

Answer 16

Public safety measures

Question 17

Examples of Low Latency Services

Answer 17

Public Services, mission critical communications

Question 18

Skyship

Answer 18

platform in South Korea used to help medical crew to find survivors to disasters; it uses robots and drones to find survivors. The lastest version uses 5G

Question 19

industries where mission-critical communication is crucial in supporting continuous safety improvements and increased operational efficiency

Answer 19

railroads, mining, aviation

Question 20

What are mission critical systems

Answer 20

Anything that would severely impair your business if it stopped

Question 21

GSMA Predictions about 5G quota on global mobile connections by 2025

Answer 21

By 2025, GSMA Intelligence predicts that 5G will account for 25 per cent of global mobile connections.

North America- 60%

Asia pacific (South Korea, Singapore, Australia, Japan - 64%/ In the rest 8%)

Middle East and North Africa (MENA) 17% (However Golf Cooperation Council Arab States [Saudi Arabia, Kuwait, Oman, Barain, United Arab Emirates) 49%, and the rest of MENA 12%)

Europe 44% (Leading countries UK, Germany and France)

Greater China - 52%

Subsaharan Africa - 4%

Latin America - 11%

Question 22

Which segment is expected to create the most important source of new revenue in the 5G era and why

Answer 22

Enterprise segment (69%)

Question 23

Network slicing

Answer 23

the process of creating virtual networks, that are tailored to specific types of applications, on top of the physical network. La idea es que no todos los usuarios necesitan el mismo bandwidth al mismo tiempo.

Network slicing, cut the bandwidth into slices, depending of the users need. For the carrier this means satisfying the needs as well as charging it correctly

Question 24

Core, what changes with 5G

Answer 24

technology that makes the network work behing the scenes(behind the network tower)

In the past, thats all been dedicated equipment (switch, router, radio) but now were moving to something called nfe network function virtualization, which uses standard computers with a few accesories (such as usb) and you can program the core of the network to do whatever it needs to do)

Question 25

What in 5G core makes network slicing possible

Answer 25

Network function virtualization

Question 26

How does network slicing creates a form of new revenue for operators

Answer 26

It allows them to attend the specific needs of users, therefore charge them properly (as opposed to providing the bandwidth indiscriminadamente)

Question 27

Stakeholders priority of uses cases and other perspective

Answer 27

Telematics, public safety, health monitoring, smart grid, mobile banking

Other perspective for operators

Question 28

new horizons 5G

Answer 28

automated controls, real time telematic, real time video uplink, remote control, ehealth, smart metering sensors network

Question 29

What are the approaches to 5G deployment and the criteria to opt for them

Answer 29

Standalone 5G Network (SA) and Non - Standalone 5G Network (NSA)

Question 30

Edge Computing (Multi Access Edge Computing) and Big Data Analytics

Question 31

public switched telecommunications network (PSTN)

Question 32

Core Network
