Prospects for Improving Competition in Mobile Roaming
WIK Wissenschaftliches Institut für Kommunikationsdienste GmbH Prospects for improving competition in mobile roaming Ulrich Stumpf Paper prepared for the 29th TPRC 2001, 27 - 29 October 2001, Alexandria, Va. Prospects for improving competition in mobile roaming I Contents Abstract II 1 Introduction 1 2 Basics of international roaming 2 3 Supply-side of wholesale roaming markets 7 3.1 Small number of suppliers and high market concentration 8 3.2 Spectrum scarcity and second-mover disadvantages 9 3.3 Imperfect substitutes to wholesale roaming 12 3.4 Transparency of competitors’ IOTs 13 4 Demand-side of wholesale roaming markets 13 4.1 Lack of competitive pressure in downstream retail roaming markets 14 4.2 Customer ignorance, insufficient control over network selection, and demand externalities 17 5 Conclusions and implications for application of non-discrimination rules 21 References 23 Prospects for improving competition in mobile roaming II Abstract The ability to make international roaming calls is of increasing importance to customers. However, there are various complaints that prices of retail roaming are intransparent, rigid and at levels that are unrelated to the cost of carriage. The focus if the paper is on wholesale roaming, which is the prime determinant of retail roaming prices. The paper analyses the structural conditions of wholesale roaming markets that have impaired incentives to competition, namely (1) high combined market share of the two leading operators combined with second mover disadvantages, and (2) demand externalities associated with customer ignorance and lack of control over network selection. The paper argues that a number of developments are under way that are likely to modify this situation in the future. -

Cellular Technologies Mobile Device Investigations Program Technical Operations Division - DFB DHS - FLETC Basic Network Design Frequency Reuse and Planning 1. Cellular Technology enables mobile communication because they use of a complex two-way radio system between the mobile unit and the wireless network. 2. It uses radio frequencies (radio channels) over and over again throughout a market with minimal interference, to serve a large number of simultaneous conversations. 3. This concept is the central tenet to cellular design and is called frequency reuse. Basic Network Design Frequency Reuse and Planning 1. Repeatedly reusing radio frequencies over a geographical area. 2. Most frequency reuse plans are produced in groups of seven cells. Basic Network Design Note: Common frequencies are never contiguous 7 7 The U.S. Border Patrol uses a similar scheme with Mobile Radio Frequencies along the Southern border. By alternating frequencies between sectors, all USBP offices can communicate on just two frequencies Basic Network Design Frequency Reuse and Planning 1. There are numerous seven cell frequency reuse groups in each cellular carriers Metropolitan Statistical Area (MSA) or Rural Service Areas (RSA). 2. Higher traffic cells will receive more radio channels according to customer usage or subscriber density. Basic Network Design Frequency Reuse and Planning A frequency reuse plan is defined as how radio frequency (RF) engineers subdivide and assign the FCC allocated radio spectrum throughout the carriers market. Basic Network Design How Frequency Reuse Systems Work In concept frequency reuse maximizes coverage area and simultaneous conversation handling Cellular communication is made possible by the transmission of RF. This is achieved by the use of a powerful antenna broadcasting the signals. -
Inside the Mobile Revolution
Inside the Mobile Revolution A POLITICAL HISTORY of GSM Europe's most successful industrial policy intervention – propelling mobile phones into the hands of over 4 billion people STEPHEN TEMPLE CBE 1 2nd Edition Copyright © Stephen Temple 2010 May be used free of charge but may not be changed in any way or used in part or in whole in another published works in whatever medium without the author's permission 2 Foreword Over the period 1984-87 the political and strategic direction of GSM was being shaped by France, Germany, Italy and the UK. It was the genesis of the mobile revolution. This is the UK record of what happened, how it happened, why it happened and captures the political dynamics within which it all took place. The GSM 1800 MHz (PCN) element was added a few years later when the UK's DTI was at the leading edge of telecommunications liberalisation and I propelled it to be the first credible entity to set out the vision of the personal mobile phone as a consumer product (‘Phones on the Move’) and put forward the conditions to make it happen. My election as Chairman of the Technical Assembly of the European Telecommunications standards Institute in 1988 then provided an excellent vantage point as GSM went through its transition from a policy to a new born infant digital mobile industry. All this left me sitting on a unique (although in parts partial) account of how GSM came to be the mobile radio equivalent of the cosmic “big bang” and one of Europe's most successful high technology projects. -
1 “Must-Read” Mobile Technology Research: a Field Guide Gerard Goggin, Rich Ling, and Larissa Hjorth with Over Seven Billion
“Must-Read” Mobile Technology Research: A Field Guide Gerard Goggin, Rich Ling, and Larissa Hjorth With over seven billion subscriptions worldwide, the social impact of mobile technology now rivals television, radio, and newspapers. The nomenclature “mobiles” has come to stand in for the variety of practices and affordances including mobile media, mobile communication and mobile technology. Mobile devices are ubiquitous as they all-pervasive. Mobiles take forms from classic mobile cellular phones, cheap- and-cheerful handsets, or luxury phones through feature phones, smartphones, pads and tablets, and multimedia devices to cross-overs with location technology, wearable computers, and driverless cars. Mobile technologies have had a profound influence on society, politics, economy, culture, relationships and identity. Mobiles also have wide-ranging implications for business, government, households, civil society, the private sphere all the way to new kinds of publics. The beginnings of the field of mobile technology can be seen in the engineering, physical sciences, computing, and information services, and other disciplines. Mobile technologies have been incubated and studied in many applied technical and design fields, especially innovative areas associated with new developments in telecommunications, computer, and data networking. Since their emergence in the late 1970s, mobile technologies have emerged as a major area of research, public discourse, debate, theory, policy and design across sociology, communications, media, and cultural studies, anthropology, politics, law and policy, economics, literary studies, area studies, as well as other areas of the humanities and social sciences. This collection especially focuses on the humanities and social sciences research on mobile technologies. It does not neglect its vital interactions with research in the wide range of other scientific, technological, biological, information, design, and other sciences engaged in mobile technologies. -

As the Internet revolution evolves into the Mobile Internet revolution the need for usable and desirable wireless services is increasing. Designing web based services for mobile devices and mobile users is significantly different than designing web based services for desktop use. Not only are there differences in the underlying technology but also, and perhaps most important, in the way people use the services. -
