ince mobile cellular became commercially available in the early 1980s, it has advanced beyond imagination in terms of coverage, services, technology, handsets and regulation. Perhaps the most revolutionary change is that in the space of around 20 years, mobile subscribers surpassed fixed-telephone line subscribers in 2002, making mobile technology the predominant means of voice communications (see Figure 1, left chart). First generation mobile cellular networks employed analogue technology. Developments in digital technology led to second-generation (2G) systems. By the end of the 1980s, 2G networks

had been developed to provide better quality services, greater capacity and additional functionality than analogue systems. At the end of 2002, the world had almost completed the transition to digital cellular networks, with analogue users accounting for a mere three per cent of total mobile subscribers. There are four 2G digital cellular radio technologies in use around the world (see Figure 1, right chart): 1  Global System for Mobile Communications (GSM).

Some 360 billion SMS were sent over GSM networks in 2002.2 Mobile handsets are also increasingly being used to access the Internet. This has become successful in countries such as Japan, where 80 per cent of cellular users subscribe to a mobile Internet service provider.3 The growing use of mobile data has led to demand for faster speed than the initial transmission rate of 9.6 kbit/s for GSM. This is being accomplished by upgrading existing GSM networks with the deployment of General Packet Radio Service (GPRS) technology. In the case of cdmaOne networks, they are being enhanced with CDMA2000 1X technology.

The development of 3G systems The need for faster speed, global compatibility and multimedia services has led to the development of 3G systems. In an effort to consolidate existing incompatible mobile environments into a seamless global network, ITU adopted a family of radio access methods at its Radiocommunication Assembly in Istanbul in early May 2000.

3G Licensing At the end of 2002, there were 119 licences that had been awarded to operators around the world for the use of IMT-2000 spectrum to offer 3G mobile services. An important consideration in the 3G licensing process is exactly what is being offered. In most countries, the licensing includes the needed spectrum, typically in the 2 GHz range. In some cases, particularly most of Europe, the 3G radio interface was also specified. In other cases, there was no explicit requirement for a specific radio interface as long as it was one identified in the IMT-2000 standard. While auctions and beauty contests have been the preferred licence allocation methods, some countries have automatically granted 3G licences to incumbents. For example in Europe, 3G licences were offered free of charge to the incumbent mobile operators in the Isle of Man, Liechtenstein and Monaco. The optimum method of allocating licences is subject to debate. Proponents of auctions will argue that frequency is a scarce resource and its pricing should be left to the market. Backers of beauty contests will argue that their method avoids high auction prices that will eventually be passed on to consumers. There are also political aspects since, in some instances, the licence fees revert to the government budget. Auction In this method of licence allocation, a frequency range identified for the use of 3G networks is auctioned. A number of licences are made available depending on spectrum and market conditions. Successful applicants are those that outbid others. There has been great variation in the relative price paid for 3G licences that have been auctioned. The average price per capita in Germany and the United Kingdom amounted to EUR 615 and 644 respectively. In contrast, Austria and Denmark collected an average licence price per capita of EUR 103 and 95. One reason is timing. Germany and the United Kingdom were among the first to auction 3G licences. Euphoria was

high, as were the prices. It is possible that licences will be sold at or near their reserve price (i.e., minimum bid price) when the number of bidders is the same or less than the number of licences available. Such was the outcome when Switzerland conducted its auction in December 2000. Auctions can also be cancelled under such circumstances, as was the case in Singapore and Slovenia where the bidders simply paid the reserve price. In total, 77 licences for 3G have been granted in 19 economies via auctions, accounting for USD 101 billion (see Table 1).

Beauty contest In a beauty contest, a fixed number of licences are awarded to applicants that best meet certain criteria. The regulator issues an invitation to all interested parties with guidelines and requirements. Successful applicants are chosen based on specific pre-determined criteria presented in the application. The selection criteria differ from country to country, depending on the respective plans and objectives in establishing a 3G network. In general, applicants are evaluated based on their financial capacity, business plan and technical expertise. Criteria that are often used are commitments to rapid roll-out and with high levels of land and population coverage. Other aspects such as market concentration and technological specifications are also taken into consideration. Like a real beauty pageant, applicants are awarded points for satisfying the specific criteria stipulated. Applicants with the highest scores are awarded licences. Normally, licensees also pay a fixed licence fee, but some countries, like Japan and Finland, waived this fee. In this method, licence costs are significantly lower than the auctioned licences, yet France and Poland were noteworthy for having high fees. Some 41 3G licences have been issued in 13 countries via beauty contests accounting for USD 6.9 billion (see Table 2).

Personal Communications Services (PCS) that take up parts of the spectrum bands identified for 3G services. There are several factors holding back the allocation of additional spectrum for 3G in the region. One is that local operators have already invested heavily in building their 2G networks (in the 1900 MHz band). Additional spectrum would require more investments

which operators are presently unable or unwilling to make. Another factor is the plurality of different systems in the region (i.e., TDMA, GSM and CDMA), which complicates the migration path from 2G to 3G. In some countries, spectrum in the IMT-2000 bands cannot be made available as it is used for national security purposes. Finally, existing spectrum bands (1850–1990 MHz) can be used to provide 3G-type services and operators in the region with CDMA networks are choosing to evolve to CDMA2000 1X (recognized as an IMT-2000 standard) without the need for additional spectrum. No African country has issued licences for IMT-2000. In most African countries, there are already many more mobile than fixed telephone subscribers, so 3G could be a key technology for enhancing Internet penetration in the region. While no formal IMT-2000 licensing has taken place, it could be that operators in some African countries may introduce 3G-like services within existing frequency allocations. These include fixed wireless operators using CDMA that hope to introduce a mobility mode. For example, a Nigerian telecommunication operator has announced plans to launch a CDMA2000 1X network. 5 5

Conclusion There have been considerable delays in the introduction of 3G and market penetration of licensed systems was less than 0.4 per cent of total worldwide mobile subscribers, some four years after the licence process began. Few EU countries met the directive of launching commercial 3G services by 1 January 2002. In retrospect, 3G licensing can be questioned on two grounds. One was the EU process that compelled members to abide by a specific timetable. It is debatable whether this was practical

that have launched those networks refer to them as 2.5G. A CDMA2000 1X network offers data speeds of 144 kbit/s versus 384 kbit/s for W-CDMA. The majority of countries in the world have yet to license or deploy 3G networks. The contrast is even starker between developed and developing nations. Countries that have not yet licensed IMT-2000 networks have several options, based on the benefit of hindsight. One is that there may be no hurry to license 3G. The first W-CDMA 3G networks have only recently been deployed at great cost — and all in developed nations. At this point in time, it may prove difficult for many developing countries to find investors willing to invest in a brand new 3G network. Instead, countries might consider upgrades to existing networks, evolving them to 2.5G as a first step to 3G. For GSM networks, this means the deployment of GPRS while for cdmaOne networks it involves the installation of CDMA2000 1X.
