5G Use cases Flashcards
What are use cases attributed to 5G
Enhanced Mobile Broadband, Fixed Wireless Access, Massive Iot
Limitations of 5G FWA
- 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
Type of spectrum used for 5G FWA
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
costs of providing FWA vs deploying fixed connections
70% costs reductions and easer to install by user
Limits of millimetre spectrum
Limited ability to penetrate buildings and has a reduced range
What are the new uses cases of 5G
Massive IOT and Ultra Reliable Low Latency Communication (URLLC)
5G Capabilities
- Massive Connectivity 2. Capacity Enhancement 3. Low Latency
Services related to enhanced mobile broadband
Security cameras, transfer gigabytes in a second, 4K 3D video, work and play in the cloud, augmented reality, industrial and vehicular automation, voice calls
Services related to low latency
mission critical broadband and self driving cars
Services related to massive IoT
sensor network
5G specific Iot Technology
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
5G Targets Iot Tech
NB-Iot 15 km coverage / 150 kbps throughput/ 10 year battery life
LTE-M 11 km coverage / 1 mbps throughput / 10 year battery
Examples of new 5G uses
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
4G vs 5G Latency
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
Impact of 5G Low Latency feature + Massive Iot Capabilities of Iot
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
What is eMBMS used for in 5G in addition to broadcast
Public safety measures
Examples of Low Latency Services
Public Services, mission critical communications
Skyship
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
industries where mission-critical communication is crucial in supporting continuous safety improvements and increased operational efficiency
railroads, mining, aviation
What are mission critical systems
Anything that would severely impair your business if it stopped
GSMA Predictions about 5G quota on global mobile connections by 2025
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%
Which segment is expected to create the most important source of new revenue in the 5G era and why
Enterprise segment (69%)
Network slicing
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
Core, what changes with 5G
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)
