These modulators exhibit large bandwidths with low drive power requirements and offer the potential for integration with other optoelectronic devices

The rollout coverage will be higher in the densest areas. It is also assumed that the traffic per user is higher in the densest areas. Forecasts for mobile broadband accesses and the traffic per user in the peak hour is an important part of the analysis. The traffic forecasts are used to make a strategy for upgrading the capacity of the base stations based on throughput calculations for upgrading with additional sectors, additional carriers and HSPA 3.6, 7.2 and 14.4 Mbps respectively. Techno-economic calculations are performed for the rollout cases based on ARPU predictions, cost evolution of the network elements, evolution of OPEX and assumption of future market share and competition. The long-term access and traffic forecasts are uncertain. To examine the impact, techno-economic calculations are performed for increasing forecasts.

Specific attention is put on market risk, competition risk, regulatory risk, technology risk and operational risk. The risk methodology developed in the ACTS projects OPTIMUM and TERA is described. The paper shows how the risk methodology can be applied for evaluation of various network architectures. The paper also presents risk and techno-economic analyses of broadband access network upgrade strategies for public network operators in a competitive environment in the residential and small business market. The effect of uncertainties in predictions of critical parameters such as demand forecasts and market shares are analysed

The paper gives an overview of the driving factors for the traffic growth. Long-term forecasting models for mobile broadband penetration of different subscription types combined with models for traffic forecasting per subscriptions are used to make busy hour traffic forecasts up to 2016. The forecasts are used for network dimensioning, upgrade planning and roll out of new technology.

Cable operators in Europe and North America have for a while offered broadband Internet service bundled with TV and telephony. The incumbents in most European countries offer ADSL services to the residential market. However, ADSL does, as opposed to VDSL, not offer the same triple play option as upgraded cable networks. Incumbents only basing their future broadband offer on ADSL in areas with established cable operators are therefore faced with the risk of considerable losses in potential revenue. In addition, the national regulatory authorities have obliged the incumbents to offer unbundling of the local loop giving OLOs the possibility to compete directly with the incumbent not only onADSL market but eventually on VDSL as well. However, the marginal cost of rolling out VDSL is high to even prohibitive in certain geographic areas. It is therefore...

The broadband penetration forecasts are adjusted according to the broadband coverage. The adjusted forecasts are defined as adoption rate forecasts. These forecasts are used as input to the techno-economic calculations to examine broadband roll out in the different access area types. The paper documents the profitability of broadband rollouts in sparsely populated areas and estimates the limits for having monopoly areas as a function of given characteristics. The identified monopoly areas will of course contribute to higher broadband coverage because the profitability in these small areas will be better than earlier expected because of none competition.
