Will telecommunications policy in the form of industry-specific regulation go away? A literature review of the five policy areas (1) termination monopoly, (2) local bottleneck access, (3) net neutrality, (4) spectrum management, and (5) universal service suggests that in some of them a move to competition policy will soon be the efficient state of the art, while regulation will remain efficient in others for some time. In particular, some regulation should persist for net neutrality in the form of transparency requirements, (quasi-)common carrier obligations and minimum quality standards. Also, spectrum management will continue to see regulators provide zoning and other services, in particular for unlicensed spectrum.

The Endgame of Telecommunications Policy? A Survey

Our survey reviews the theoretical and empirical literature on all alternative policies to promote the deployment of new fiber-based communications infrastructure Since such investment is expected to induce substantial positive externalities, dynamic efficiency becomes a particularly important policy goal The available policies refer to i) different kinds of ex ante sector-specific regulations including cost-based access regulations as well as softer regulations such as regulatory holidays or geographically differentiated regulations, ii) deregulatory approaches based on effective competition law implementation and competitive market structures including allowance of co-investment models, and iii) public subsidies to cover non-profitable (“white”) areas Our survey identifies the most significant research gaps, finding that numerous studies related to the impact of access regulations exist, whereas only a much smaller branch of literature addresses the impact of competition policies, and even fewer studies analyze the impact of public subsidies on new communications deployment Moreover, our work allows for a generic framework for policy recommendations that identifies the comparative advantages of the individual policy options for different market structures and for varying degrees of externalities We find that public subsidies are the dominant policy alternative in white areas, whereas access regulations can be the preferred policy in white or “grey” areas, where only monopoly structure or co-investment models lead to private investment Deregulatory policies might be preferable in grey areas, if there is sufficient pressure from competitive outside options and if competition law is strong Finally, deregulatory policies including soft regulation are the dominant policy in “black” areas, where several independent infrastructure operators exist

The Impact of Alternative Public Policies on the Deployment of New Communications Infrastructure – A Survey

This article examines the cost implications of a network-sharing scheme for different fiber to the home/passive optical network (FTTH/PON) architectures. Varied metrics are employed to understand the effect of a network-sharing arrangement on costs. The results show that for the majority of cases studied the cost per home connected and the payback period increase when employing a network-sharing scheme, but the initial investment is strongly reduced. The reuse of existing passive infrastructure does not bring any cost advantage in comparison to the stand-alone scenario, but it helps to reduce the total cost per home connected.

Economic implications of a co-investment scheme for FTTH/PON architectures

5G systems will enable an improved transmission performance and the delivery of advanced communication services. To meet the expected requirements, operators will need to invest in network modernisation, with the radio access network being the most expensive network component. One possible way for operators to reduce this investment would be via sharing of resources by means of a multi-tenancy concept. This implies that a mobile service provider may use the common infrastructure of one or various infrastructure providers, whereby it provides services to multiple tenants. This paper aims to study the expected cost savings in terms of capital expenditures (CAPEX) and operational expenditures (OPEX) that can be achieved when using a cloudified 5G multi-tenant network.,A cost model was used. The study period is 2020-2030 and the study area consists of three local districts in central London, UK.,This paper describes that the total cost reduction achieved when using multi-tenancy for a 5G broadband network in comparison with the case where operators make the investment independently ranges from 5.2% to 15.5%.,Further research is needed to assess the cost implications of network sharing for 5G on a regional or nationwide basis.,Very little quantitative research about the cost implications of network sharing under 5G networks has been published so far. This paper sheds light on the economic benefits of multi-tenancy in a 5G broadband network.

Cost assessment of multi-tenancy for a 5G broadband network in a dense urban area

Purpose – This paper aims to describe the effect of VoIP network architectures on the cost modelling of termination rates of VoIP services.Design/methodology/approach – The study investigates and organises the arguments available in the technical and regulatory field related to VoIP networks and services in order to ascertain the possible impact of VoIP techniques, the provisioning of voice features in VoIP networks, and network interconnection issues on the cost of regulated VoIP services.Findings – The information and analysis reveals how the provision of VoIP services is related to a number of issues that will have an effect on the cost of VoIP termination rates. In particular, the study analyses the impact on a cost model of the components of a VoIP network architecture, the usage factor of network elements, and the traffic volume generated by VoIP applications.Research limitations/implications – The issues described in the article can be used in elaborating a cost model for termination rates in VoIP ...
