In the past, as new technologies and services
developed, legal and regulatory frameworks often evolved in a piecemeal fashion,
with regulators often charging different fees, using different assignment mechanisms,
and imposing different conditions on the various types of spectrum authorizations
or licenses. However, these practices do not facilitate converged service offerings
or maximize the value and use of spectrum, since new technologies enable multiple
services and applications to be provided over one network, allow multiple services
to be provided using the same spectrum, and enable the spectrum to be used more
efficiently and intensively.
As a result, policy makers
and regulators are looking to replace narrowly defined technical and service rules
with more flexible assignments that allow providers to match their network and service.
In today’s broadband environment, access to spectrum is particularly relevant, given
the anticipated likelihood that for many countries, particularly developing ones,
wireless will be the primary vehicle for deploying broadband networks. For example,
in Morocco, third-generation (3G) mobile broadband connections surpassed asymmetric
DSL (ADSL) wireline connections in September 2009 and represented over 76 percent
of the total Internet connections in the country as of March 2011 (Morocco, ANRT
2011). As a result of this trend, regulatory authorities and policy makers in many
countries are looking at legal and regulatory reforms as necessary to facilitate
the supply of wireless broadband services and the build-out of networks. Such policies
include spectrum allocation and licensing, license terms and conditions (for example,
coverage obligations), license renewals, and procedures to reclaim and reuse spectrum
(for example, the transition from analog to digital television).
3.3.1 Spectrum Licensing Regimes
The process for licensing spectrum use typically
depends on a country’s general licensing regime for electronic communications services.
The traditional approach that developed in many countries was to issue a service-specific
license to cover both the network or service and the spectrum in a single document.
For instance, prior to adoption of the unified access service license in India,
the cellular license was one of 12 service-specific licenses under the traditional
framework (TRAI 2003, 8). As is typical under a traditional licensing framework,
tying the network, service, and spectrum license together may limit or eliminate
the ability of licensees and consumers to capture the benefits of convergence.
More recently, converged
licensing frameworks have developed that generally involve two authorizations: one
covering the networks and services to be provided and another covering the spectrum.* Additionally, the network
or service and spectrum licenses may be issued separately. If issued separately,
the licenses to provide networks and services should be granted or registered simultaneously
with the spectrum licenses to ensure regulatory certainty.
Regardless of the initial
procedures for issuing spectrum licenses, spectrum licensing regimes for commercial
services should be as flexible as possible, since limiting the flexibility of spectrum
licenses can diminish the value of the broadband service and ultimately undermine
the service provider’s investment incentives (Kim, Kelly, and Raja 2010, 47). Regulators
can introduce flexibility through rules that are technology and service neutral,
allocating certain frequency bands for unlicensed or license-exempt use and using
market-based assignment mechanisms, including spectrum trading.
3.3.2 Flexible-Use Technical and Service Rules
A key tool for promoting wireless broadband
development is for governments to allow flexible use of spectrum, particularly through
technical and service rules that enable wireless providers to offer any type of
broadband service or application, including voice, video, and data. Flexible-use
rules may be applied to both current and future commercial assignments to maximize
the benefits of technological evolution and development of advanced services. For
example, the EU’s 1987 Global System for Mobile Communications (GSM) Directive reserved
the 900 megahertz (MHz) band (890–915 MHz/935–960 MHz) for GSM networks and services
only; however, this was revised in 2009 to permit greater flexibility in choice
of technology and encourage the growth of mobile broadband in this band (European
Union 2009c).
When considering adopting
flexible-use rules for existing licenses, however, regulators should evaluate the
potential competitive implications of such liberalization and the possible safeguards
that would need to be put in place to address them. This includes determining whether
this policy would place certain providers at a competitive advantage vis-à-vis their
rivals or whether operators should be allowed to retain all or part of the liberalized
spectrum. In case existing providers are allowed to retain the spectrum, the regulator
should consider the possible mechanisms to control for potential windfalls (for
example, regulatory obligations and fees). If some spectrum is to be released back
into the market, the regulator should also consider the manner and timetable in
which the assignment of such spectrum will take place. Regulators will also need
to address the impact that flexible-use rules for broadband spectrum licensing will
have on processes in their pipeline, including the assignment of various spectrum
bands in a single process or the adoption of caps to facilitate new entry or make
it possible for an operator to obtain an even blend of spectrum across different
bands.
Cognitive radio technologies
(CRTs) are also expected to lead to a significant increase in the flexible use of
spectrum. A cognitive radio is able to sense and understand its local radio environment
and to identify temporarily vacant spectrum in which to operate. At present, most
attention relating to CRT is placed on opportunistic or unlicensed use (that is,
identifying “unused” portions of spectrum using CRT and sharing the spectrum dynamically
with existing users), but it is expected that in the future licensed operators may
use CRTs to improve the management of their spectrum assignments. This represents
significant opportunities to optimize the use of spectrum for the provision of bandwidth-intensive
wireless broadband services and applications.
3.3.3 Spectrum Allocation and Assignment
As the deployment and adoption of wireless
broadband increases, additional spectrum is widely expected to be needed to accommodate
the demand of bandwidth-hungry broadband services, including video and data. For
example, the average smartphone user generated 10 times the amount of traffic as
the average non–smartphone user between 2009 and 2010. And the number of smartphone
users is expected to grow substantially—it is anticipated that most people in the
world will use mobile devices as their primary connection to the Internet by 2020
(GSA 2010).
Beyond introducing converged,
flexible licensing frameworks, countries are also looking at the way (a) spectrum
bands are planned and harmonized and (b) spectrum blocks are configured, assigned,
and transferred. Wherever possible, a key initial step in promoting commercial wireless
broadband networks and services is for regulatory authorities to adopt internationally
harmonized band plans when considering the allocation and assignment of spectrum.
This approach facilitates the commercial launch of broadband services by allowing
providers to take advantage of scale economies in network equipment and devices,
thus reducing the costs of deployment and, ultimately, the prices for consumers.
International harmonization also facilitates the ability to offer roaming services.
Wireless broadband also
requires additional bandwidth to be made available to keep pace with the high data
rates needed to support bandwidth-hungry services and applications, such as video.
The specific amount of spectrum will vary by country, depending on the current assignments
and the expected growth in the demand for data services and traffic. Nevertheless,
to deliver new data-intensive services and applications in a technically efficient
and cost-effective manner and at the desired level of quality, providers will need
to obtain additional spectrum. This is especially the case in large, densely populated
urban areas in both developed and developing countries. For example, the U.S. National
Broadband Plan seeks to make 500 MHz of spectrum available for broadband use by
2020, of which 300 MHz between 225 MHz and 3.7 gigahertz (GHz) should be made available
by 2015.
In addition, the size
of the spectrum blocks awarded to licensees may need to be revisited. For example,
scalable, new International Mobile Telecommunications-Advanced (IMT-Advanced) technologies
are best suited for wider blocks of contiguous spectrum, ranging from 2x15 or 2x20
MHz for paired spectrum and a minimum of 20 MHz for unpaired spectrum. Therefore,
regulators are increasingly designating larger spectrum blocks for the provision
of wireless broadband services. Recent assignments for IMT in countries such as
Brazil, Chile, Costa Rica, Colombia, Denmark, the Netherlands, Norway, and Mexico
highlight this approach.
Also relevant is the
method of awarding spectrum. Increasingly, countries are using market mechanisms to assign spectrum use rights, particularly through auctions.
Competitive award methods are generally viewed as more open, nondiscriminatory,
and transparent than other assignment processes, such as administrative proceedings,
and they provide an opportunity for new entrants. Auctions are also more economically
efficient, since those willing to pay the highest price place the most value on
spectrum, while the winning bids provide additional revenues to governments. For
example, India’s 2010 auction of 3G spectrum garnered over US$14.5 billion for the
government (Kinetz 2010).
Spectrum trading (also
known as “secondary markets”) is another method that facilitates aggregation of
spectrum to meet future data traffic demand requirements by permitting existing
licensees to transfer all or a part of their spectrum assignments to third parties
with little or no government involvement in the process. Implemented in Australia,
New Zealand, and the United States, spectrum trading has allowed late entrants to
the mobile market to obtain spectrum rights, which can reduce constraints on new
entrants with regard to the timing of their market entry. In the absence of spectrum
trading, potential entrants and existing operators seeking to build out their networks
further must wait for the government to award new spectrum assignments. Ultimately,
spectrum trading provides the opportunity for secondary markets to emerge that can
improve the rollout of new services, increase the potential for competitive service
provision, and encourage investments in the sector (for an in-depth study of spectrum
management and reform in developing countries, see Wellenius and Neto 2008).
Although placing greater
emphasis on market forces and spectrum trading offers many advantages over the traditional
models of spectrum management, ineffective regulatory environments may allow incumbent
or dominant operators to control key, high-value spectrum bands. This could result
in spectrum hoarding and concentration of the wireless broadband market. As such,
there is a trade-off between operators having sufficient spectrum and monopolizing
the available spectrum. Many countries seek to mitigate this through build-out obligations,
while others impose spectrum caps or set aside spectrum blocks for new entrants.
However, at least one study argues that spectrum caps in Latin America may hinder
the development of mobile broadband.*
Overall, making as much spectrum available as possible through transparent and nondiscriminatory
procedures is a key step toward ensuring that operators are able to meet future
wireless broadband demands.
3.3.4 Spectrum License Renewal
As spectrum licenses granted in the 1990s
and early 2000s reach the end of their initial terms, license renewal policies will
become an increasingly relevant regulatory issue to fostering investment in wireless
broadband. In establishing renewal policies, policy makers and regulators should
strive to promote investors’ confidence and provide incentives for long-term investment,
while preserving the flexibility of the regulatory process to accommodate market
and policy developments (Guermazi and Neto 2005, 2). Legal certainty is of utmost
importance to create an environment conducive to investment and the technological
upgrades required to deploy wireless broadband services.
3.3.4.1 Principle and Procedure for Renewal
While legal regimes vary, most frameworks
have adopted a system based on the “presumption of renewal” or “renewal expectancy.”
Under a presumption of renewal, the licensing authority must renew a license as
long as the licensee has fulfilled its obligations and has not violated the law
or the terms of its license. In general, renewal expectancy provisions seek to provide
regulators with the flexibility to review and adjust license conditions in response
to technological developments and market conditions, while providing the regulatory
certainty necessary for licensees to continue investments. In Canada, for example,
the licensing framework provides a high expectation of renewal unless a breach of
license condition has occurred, a fundamental reallocation of spectrum to a new
service is required, or an overriding policy need arises.*
Similarly, in Antigua and Barbuda, there are both a renewal expectancy for the same
period as the original license and a requirement for the regulator to provide 180
days written notice of its intention not to renew. An appeals process to the regulator
is also established.
Other countries rely
on automatic renewals. For example, Portugal’s Decree-Law no. 151-A/2000, regarding
the use of radio communications, automatically renews licenses every five years
unless the regulator provides at least 60 days written notice to the licensee stating
the reasons for nonrenewal.*
In the Dominican Republic, automatic renewal is warranted in the absence of a negative
finding from the regulator. Some countries, such as Australia, provide less long-term
certainty to incumbents, opting instead for a legal presumption that, when a spectrum
license expires, the license will be reassigned via a
price-based method (for example, auction), unless it is in the public interest to
do otherwise.*
3.3.4.2 Change in License Conditions and Review of License Fees
Renewal
expectation, however, does not necessarily imply that licenses will be renewed under
the same terms as the original license. In setting the terms and conditions of license
renewal, regulators must strike the right balance between giving certainty to operators
and investors and ensuring that license conditions reflect current policy objectives,
respond to technological and market developments, and consider the consumers’ needs.
If an appropriate balance is not struck, proposed changes to licenses and the review
of associated fees in particular can become highly controversial.
For example, France’s regulator, ARCEP (Autorité de Régulation
des Communications Électronique et des Postes), initiated
a public consultation in 2003 on the renewal of GSM licenses, which were set to
expire in 2006 and 2009 (France, ARCEP 2003). ARCEP originally announced that it
would charge a 5 percent progressive tax on annual turnover, but licensees protested
that this amount would harm investment and the development of services. The regulator
issued its decision in March 2004 after comments from licensees demonstrated that
the high annual fees would negatively affect investment and the market generally
(France, ARCEP 2004b). Although the government set out new licensing fees, as well
as higher coverage obligations and quality of service levels, the annual fees were
substantially less onerous (France, ARCEP 2004a). The new fees required GSM licensees
to pay €25 million annually and 1 percent of annual turnover (France, Ministry of
the Economy, Finance, and Industry 2004). A similar controversy surrounded
the renewal process for mobile licenses in Bangladesh, where a proposal to extract
large renewal fees from existing licensees and the imposition of additional obligations
created significant opposition from service providers, apparently causing the government
to abandon the idea.*
3.3.5 License-Exempt (Unlicensed) Spectrum
In an effort to provide maximum flexibility
for innovation and lower entry costs for some types of ubiquitous wireless devices,
policy makers and regulators in many countries have set aside certain bands exclusively
for license-exempt (also known as unlicensed) uses. In other bands, license-exempt
devices and licensed services share frequencies. Many commonly used wireless devices,
such as cordless phones, garage door openers, and smart meters for water and gas
metering, depend on unlicensed spectrum. In addition, municipal wireless networks
also use unlicensed spectrum to create mesh networks that cover downtown areas or
even entire cities.*
Wireless Fidelity (Wi-Fi)
is perhaps the most well-known and widespread example of unlicensed use. Many countries
have opened the 2.4 and 5.8 GHz spectrum bands for unlicensed use, allowing for
the tremendous growth of Wi-Fi devices. According to ABI Research, consumer devices
with Wi-Fi functionality surpassed 770 million units in 2010, an increase of nearly
33 percent compared to 2009.*
Over half of all Wi-Fi devices are mobile handsets and laptop computers; however,
a wide and expanding range of equipment is equipped with Wi-Fi, including cameras,
fax machines, and printers. Furthermore, in many countries there has been significant
development of “Wi-Fi hotspots” in cafés, libraries, universities, and other public
areas where users can access the Internet for free or at low cost.
An important emerging
use for Wi-Fi is as a complement to commercial wireless networks. As wireless broadband
services spread, the demand placed on mobile network capacity is increasing exponentially,
putting significant strain on available resources. The combination of licensed and
unlicensed spectrum usage—Wi-Fi in particular—is becoming a key complement of the
wireless broadband experience, allowing users to offload their traffic from mobile
operators’ networks in certain circumstances, reducing potential congestion, and
enhancing broadband access.
Technical and service
rules for unlicensed spectrum typically specify that unlicensed devices must operate
at low power and may not cause harmful interference to a licensed user. In addition,
unlicensed devices must generally accept interference from licensed users and other
unlicensed devices. Although interference and economic issues may make it difficult
or impossible to replace all spectrum licenses with unlicensed use, opening bands
to unlicensed devices can support broadband development through the growth of new
technologies, efficient use of spectrum, and the entry of new network, service,
and applications providers.
3.3.6 Spectrum Refarming and the Digital Dividend
In order to maximize the ability to offer
wireless broadband, particularly where spectrum is intensively used, many countries
are engaging in spectrum refarming, whereby existing spectrum users are moved out
of a band to allow for new broadband uses. The refarming process is often lengthy
and costly, since it typically involves negotiations with existing private and public
spectrum holders and potential licensees and may also include compensation for the
existing licensees to change spectrum bands. As such, it is important to conduct
a thorough spectrum inventory to identify unused or underutilized spectrum as well
as heavily used bands before implementing a refarming process. In many developing
countries, refarming may be less necessary in the near future since available spectrum
may be sufficient and more easily allocated for wireless broadband services.
One of the most promising
and active areas of spectrum refarming is the result of the transition from analog
to digital television. As countries around the world prepare for or complete the
transition to digital terrestrial television (DTT), they are examining procedures
for reallocating the spectrum that becomes available as broadcasters vacate the
700 MHz or 800 MHz bands, depending on the region. This freed-up spectrum, which
is widely known as the “digital dividend,” offers excellent propagation characteristics
for mobile broadband services by providing an ideal balance between transmission
capacity and distance coverage. This means that the digital dividend spectrum is
well suited to providing mobile services to rural areas as well as to providing
effective in-building performance in urban areas. For countries where rural coverage
is an important policy goal, this is a notable advantage.
However, given the various
timelines for the DTT transition—some countries have completed the transition, while
others are planning for the analog switch-off (ASO) between 2011 and 2020)—many
countries are only beginning to consider rules and timeframes for refarming digital
dividend spectrum. Many countries are waiting to award digital dividend spectrum
until after the ASO is completed and the spectrum is no longer encumbered by broadcasters.
However, some countries, such as the United States, Colombia, and Peru, have awarded
or are planning to award the digital dividend ahead of their ASO dates. Regardless
of the approach, considerable international and regional harmonization is under
way, including by the EU and the Asia-Pacific Telecommunity. Box 3.1 provides an
overview of the DTT and digital dividend activities around the world.
Box 3.1 Summary of the Digital Television Transition and Digital Dividend Activities around
the World

Digital television transition timelines
vary. Developed and developing countries alike have been focusing on the
digital TV transition and most have adopted ASO dates or have at least set a goal
for completing the transition by a certain year. While countries such as Germany,
Finland, Luxembourg, Sweden, the Netherlands, and the United States have already
completed the ASO, other countries are focusing on 2015–20 to complete their transitions.
Consideration of the
digital dividend is slow. Less progress has generally been made toward developing
rules and timeframes for the award of digital dividend spectrum. While several consultations
are expected to begin over the next two years, including Chile, Colombia, Ireland,
Mexico, and the United Kingdom, most countries have not established technical and
service rules or award processes for the digital dividend spectrum, particularly
in developing countries.
Approaches to assigning
digital dividend spectrum vary. Generally countries are waiting to award
the digital dividend spectrum until after the ASO is completed and the spectrum
is unencumbered by broadcasters. For example, Finland’s ASO in the 800 MHz band
was in 2007, but licenses still have not been awarded. Some countries, however,
are following the U.S. approach and are awarding 700 MHz spectrum ahead of completion
of the digital TV transition. Ireland is likely to auction its digital dividend
spectrum in 2011, but licensees will probably not be permitted to use their new
frequencies until completion of the ASO in 2013. Colombia, Mexico, and Peru are
also considering auctioning 700 MHz spectrum before the ASO date.
International and regional
harmonization is under way. There have been significant international and
regional efforts to harmonize the digital dividend spectrum and develop common band
plans. The International Telecommunication Union (ITU)’s 2007 World Radio Communication
Conference identified spectrum in the 698–960 MHz band for IMT, and the ITU is finalizing
a revision to ITU-R Recommendation M.1036-3, which specifies plans for all bands,
including the digital dividend, identified for use by IMT. Regionally, the European
Union and the Asia-Pacific Telecommunity have agreed on common band plans for their
member states (the two plans are not the same). To date, there are no formal common
band plans for the Americas, Africa, or the Middle East.
