10 True network sharing models bring the largest benefits Masts / sites often overloaded Sam e coverage with shared antennas (Need to ex pand the transm ission network) Significant increase of RF ex posure Capex and opex savings are minim al High level of dependency from com petitors / free- rider risk Difficult to ex pand and to develop License requirements not reached Difficult to achieve equilibrium between operators Geographical sharing Mast / site and Antenna sharing + Econom ically efficient in theory + Operators have individual coverage areas + Sim ple, quick, known + Theoretically no + Savings from infrastructure coordination in roll outs Costs High coordination to open a site No capacity pooling gains No optim ization of RF ex posure Capex and opex savings are not m ax im ized High coordination in roll out Frequency sharing m ay requir regulator agreem ent Lesser ability to make major changes to roll- out policy Common shared Network UTRAN sharing + Highest level of cash flow savings, especially in the first 5 years (launch phase) + Highest level of Capex + Own frequencies = com pliant to regulation in savings + Larger coverage area is m any countries achieved faster + Savings from purchasing + Best sites re- used and m aintaining BS + Efficient use of + Each operator m ay frequencies custom ize its coverage + Optimization of RF + N core networks exposure 10

23 Need for ubiquitous broadband access is rising Teens want it everywhere they go (nomadic) Business users want it everywhere (nomadic & mobile) Various industries could boost their productivity by real- time data and control Part of many of our daily lives (summer cabins, boats, etc.) how m any of us takes care of their bills & other banking? Em ail as a connection tool? web browsing as the first source for any inform ation 23

24 Examples of use cases for Flash- 5 0 Flash- OFDM Radio Router 1. Primary broadband access in rural areas Broadband data connection 2. Complementary bb- access in e.g. summer houses 3. Portable / mobile use for business or personal use 24

25 Summary Changes in the technology, regulation and consumer behaviour will change the outlook of IT/ Telecom/ Broadcasting industry New roles and viable business models are in need Sharing networks is a trend that will intensify due to the obvious benefits it will bring Flash 5 0 MHz in Finland will be complementing to the existing businesses of fixed and mobile broadband It may well also be the catalyst that will finally open the mobile data business for the operators Digita will provide a cost effective shared network solution with equal opportunities for all operators to offer wireless broadband First experiences of Flash OFDM in practice are promising and we are truly excited to start the roll- out and launch of this service in Finland at the forefront 25
