6 5G will come gradually, not via mass investment It ll be different from what we had on 3G and 4G. They were basically a complete network update. 5G is different and I don t think you ll see anyone coming in as new entrants and taking a position in 5G It ll only be the ones who already have a solid wireless and fixed position in the market It ll also be more business case driven. We won t roll out in an entire country and hope there s a business case. It will be a much more gradual rollout, driven by specific cases No customers will need 5G for current services. They are more than served by the 4G-pluss networks that we have now So don t expect a big investment plan like the one we had on the upgrades from 3G and 4G It ll also take a long time before 5G hits the emerging markets. It ll be Norway and Sweden first and later for the rest of the portfolio Sigve Brekke, CEO Telenor Group, 22 August (source:

9 Why is 5G important for the operators? Telenor sees many new applications that require significantly faster speeds, reduced latency, and more robustness in the mobile network than 4G will ever be in a position to offer, Berit Svendsen, EVP of Telenor s Scandinavia Cluster, May

10 5G will handle growing traffic demand more efficiently - but Evolved 4G can manage traffic growth for still some years Capacity demand will imply investments, independent of technology generation 3 ways to increase network capacity Technology improvements Additional spectrum Network densification Traffic demand per area, relative to % annual growth 4G potential not fully utilized yet 10

24 Use cases: The chicken and egg problem Operators would like customers to use their services, and are hesitant to roll-out potentially expensive network solutions that they don t know if will be profitable Verticals are skeptical to commit until they see what 5G really is. Verticals may also consider that their own (potentially proprietary) solutions are sufficient for now or they simply cannot wait for 5G (like e.g. the automotive industry) There are however exceptions some companies are very outspoken in their wishes for 5G. 24

29 Someone will most likely make money from 5G but it is not clear who Someone could be any of the main players pushing strongly for 5G 5G will be a network that can accommodate a range of use-cases and vertical applications, but 5G will also need to provide many use-cases over the same network in order to make it profitable. In order to build and run a profitable network, it needs to be filled We need to balance hype vs uncertainty, use cases have to be profitable 5G is not only about B2C Consumer segment But also about B2B industry verticals Some of the use cases are totally unknown Business model Platforms and APIs will be required for offering B2B 5G services beyond connectivity 29
