“…For example, the 2nd generation (2G) mobile telephony system GSM-likely the most often quoted success story of the European telecommunications policy and market developments-is a story of the (single) GSM standard development [65,66]. Similarly, the 1G and the 3G telephony systems were studied and referred to as single standard initiatives [67][68][69]. With the development of the 3G mobile telecommunications services, however, we have seen a substantial diversification of standardisation efforts, with different technologies-as-standards being accepted under the umbrella of the Universal Mobile Telecommunications Services (UMTS) tag.…”

This chapter sets the stage for the rest of book by presenting the current state of affairs in the management of radio spectrum and related standardisation and regulatory initiatives pertaining to the emerging fields of CR and DSA. Section 1.1 discusses the international structure of spectrum management from the global ITU level down to the regional and national level. It also outlines how the ITU has started approaching the consideration of DSA challenges. The next Sect. 1.2 looks at how these efforts have been matched by the European regulators. Next, two Sects.

“…The motivation for enterprises carrying on technological innovations lies in recognizing the existence of potential profits, and the price regulation and access regulation can affect the potential profits of enterprises, thus having an influence on the innovation incentives for enterprises. Besides, governments in all regimes have some power to shape telecommunications innovation and implementation outcomes to suit policy objectives (Stewart et al, 2011). On the other hand, under the joint actions of industrial techno-economic characteristics and government regulation, the telecommunications industry evolve into a certain market structure, which determines the conducts of enterprises (that are also subject to government regulation) and market performance.…”

The technical change in telecommunications industry is tremendous, and it is exactly the continuous technological progress in telecommunications that brings sustained prosperity and development of the telecommunications industry. In this paper, the interplay between technology, market and government in telecommunications is discussed briefly in the first place, and then we introduce technology and government into the traditional SCP paradigm as essential factors which have economic meanings to construct a new industry analysis framework called TGM (SCP). Based on this framework, we propose the spiral coevolution model of telecommunications industry which elaborates on the interaction mechanism between technological innovation, government regulation and market evolution in telecommunications. Our study indicates that the evolution of the telecommunications industry is the result of technological innovation, government regulation and market competition, and among the three, technological innovation is the fundamental driving force. Compared to the "invisible hand"-market and "visible hand"government, we believe that technology is the "third hand" in telecommunications industry. The policy implications regarding these findings are given at the end of this paper.

“…As an illustration, the mobile phone industry is selected as standardisation is one of the most important issues in this field (Bekkers, Duysters, and Verspagen 2002;Saugstrup and Henten 2006;Stewart et al 2011). Among others, although this industry has evolved roughly through four eras, a great deal of attention has been paid to the 4G standards in recent years (Verizon 2012;GSMA 2014).…”

This study aims to analyse the essential patent portfolios of individual firms via bibliometric mapping. Based on the maps drawn via this method, important clusters of each company are analysed and two interpretations are made. As an illustration, the mobile phone industry is selected because standardisation is highly important for firms in this industry. Among others, long-term evolution (LTE) of the 4G era is chosen as a standard and Qualcomm, Nokia, Ericsson, and NTT DOCOMO are included as leading firms. As a result, firm-wise LTE essential patent portfolios were visualised. Based on the information given in these maps, two important clusters (i.e. the clusters composed of frequently emerging words and their periphery and the clusters including particularly noticeable terms) were analysed. In addition, two interpretations were made as follows. First, specialised and expandable technological clusters for each company (14 specialised/expandable clusters for Qualcomm, 8 for Nokia, 11 for Ericsson, and 10 for NTT DOCOMO) were identified. Second, appropriate cooperative strategies were devised according to the ownership patterns of technologies as follows. To begin with, if the technologies were owned by one company (e.g. multi-carriers, duplex channel, error correction), a non-cooperative strategy, such as non-exclusive licensing, was advised. Next, when the technology was owned by two companies (i.e. OFDM (orthogonal frequency-division multiplexing)), a cooperative strategy, such as cross-licensing, was recommended. Finally, if the technologies were owned by multiple companies (i.e. MIMO (multi-input and multi-output) and data transmission), then a cooperative strategy, such as a patent pool, was proposed.
