17. High data rate and traffic density Scenarios
Urban macro The general wide-area scenario in urban area
Rural macro The general wide-area scenario in rural area
Indoor hotspot The scenario for offices and homes, and residential deployments.
Broadband access in a crowd The scenario for very dense crowds, for example, at stadiums or concerts. In
addition to a very high connection density the users want to share what they see and hear, putting a higher
requirement on the uplink than the downlink.
Dense urban The scenario for pedestrian users, and users in urban vehicles, for example, in offices, city
centres, shopping centres, and residential areas. The users in vehicles can be connected either directly or via
an onboard base station to the network.
Broadcast-like services The scenario for stationary users, pedestrian users, and users in vehicles, for
example, in offices, city centres, shopping centres, residential areas, rural areas and in high speed trains. The
passengers in vehicles can be connected either directly or via an onboard base station to the network.
High-speed train The scenario for users in trains. The users can be connected either directly or via an
onboard base station to the network.
High-speed vehicle The scenario for users in road vehicles. The users can be connected either directly or
via an onboard base station to the network.
Airplanes connectivity The scenario for users in airplanes. The users can be connected either directly or
via an onboard base station to the network.

19. Very low latency and very high Reliability Scenarios
Motion control Conventional motion control is characterised by high requirements on the communications system
regarding latency, reliability, and availability. Systems supporting motion control are usually deployed in geographically
limited areas but may also be deployed in wider areas (e.g., city- or country-wide networks), access to them may be
limited to authorised users, and they may be isolated from networks or network resources used by other cellular
customers.
Discrete automation Discrete automation is characterised by high requirements on the communications system
regarding reliability and availability. Systems supporting discrete automation are usually deployed in geographically
limited areas, access to them may be limited to authorised users, and they may be isolated from networks or network
resources used by other cellular customers.
Process automation Automation for (reactive) flows, e.g., refineries and water distribution networks. Process
automation is characterized by high requirements on the communications system regarding communication service
availability. Systems supporting process automation are usually deployed in geographically limited areas, access to
them is usually limited to authorised users, and it will usually be served by private networks.
Automation for electricity distribution (mainly medium and high voltage). Electricity distribution is characterized by
high requirements on the communications service availability. In contrast to the above use cases, electricity
distribution is deeply immersed into the public space. Since electricity distribution is an essential infrastructure, it will,
as a rule, be served by private networks.
Intelligent transport systems Automation solutions for the infrastructure supporting street-based traffic. This use
case addresses the connection of the road-side infrastructure, e.g., road side units, with other infrastructure, e.g., a
traffic guidance system. As is the case for automation electricity, the nodes are deeply immersed into the public space.
Tactile interaction Tactile interaction is characterised by a human being interacting with the environment or people,
or controlling a UE, and relying on tactile feedback.
Remote control Remote control is characterised by a UE being operated remotely, either by a human or a computer.

33. Multiple access technologies for the foreseeable future
3G, 4G and fixed wireless technologies will exist long into the introduction of 5G (mmWave) RATs
•ROI on LTE, and LTE in un-licensed spaces yet to be fully realized
Interoperability, mobility, load balancing and aggregation will be important to deliver the best user
experience
5G, by design, is not a universal solution for every mobile connection problem

35. InternalExternalDependanciesA Step Approach towards 5G
35
Develop 5G / MEC business model & value
proposition
Evolutionary approach to
infrastructure investment
Collaborate with government & regulators
 Define focus use cases
 Develop corresponding customer offers & business case
 Build developer & app ecosystem
 Develop infrastructure investment strategy
 Leverage existing 4G
1. Build compute capabilties to process & store data
2. Ensure intelligent network connectivity for data flows
3. Collect & process data anywhere (fullfillment & aussurance) to
impact customer experience
 Develop spectrum strategy (increased complexity as it include
licensed & unlicensed spectrum)
 Secure access to fiber backhaul, prime cell tower locations &
street furniture
 Plan at micro-market level (consider 5G subventions)
