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. -

GGSSMM -- QQUUIICCKK GGUUIIDDEE http://www.tutorialspoint.com/gsm/gsm_quick_guide.htm Copyright © tutorialspoint.com GGSSMM -- OOVVEERRVVIIEEWW What is GSM? If you are in Europe or Asia and using a mobile phone, then most probably you are using GSM technology in your mobile phone. GSM stands for Global System for Mobile Communication. It is a digital cellular technology used for transmitting mobile voice and data services. The concept of GSM emerged from a cell-based mobile radio system at Bell Laboratories in the early 1970s. GSM is the name of a standardization group established in 1982 to create a common European mobile telephone standard. GSM is the most widely accepted standard in telecommunications and it is implemented globally. GSM is a circuit-switched system that divides each 200 kHz channel into eight 25 kHz time- slots. GSM operates on the mobile communication bands 900 MHz and 1800 MHz in most parts of the world. In the US, GSM operates in the bands 850 MHz and 1900 MHz. GSM owns a market share of more than 70 percent of the world's digital cellular subscribers. GSM makes use of narrowband Time Division Multiple Access TDMA technique for transmitting signals. GSM was developed using digital technology. It has an ability to carry 64 kbps to 120 Mbps of data rates. Presently GSM supports more than one billion mobile subscribers in more than 210 countries throughout the world. GSM provides basic to advanced voice and data services including roaming service. Roaming is the ability to use your GSM phone number in another GSM network. GSM digitizes and compresses data, then sends it down through a channel with two other streams of user data, each in its own timeslot. -
