6 LTE spectrum

7  At mid-2013, the main LTE frequency bands are 1800 MHz (#3), 2.6 GHz (#7) and 700 MHz (North American bands #12, 13; 14 and 17).  Regional harmonisation is probably the first step: -Americas: DD (700 MHz), AWS, 2.6 GHz -Europe: DD (800 MHz), 1800 MHz, 2.6 GHz -Asia-Pacific: 2.3 GHz, 2.6 GHz  A major hurdle for chipset and devices vendors  Roaming is not a priority today  The Apple iPhone5 did not support the 800 MHz and 2.6 GHz bands for Europe. ˃ Fragmentation is here to stay Table: Main LTE frequency bands LTE spectrum  Two different band plans in the 700 MHz bands respectively for AT&T and Verizon Wireless. ˃ Band plans are important, as seen in the USA Source: IDATE, October 2013

8 The 700 MHz band

9  The 700 MHz band corresponds to the first Digital Dividend in the USA and in Asia-Pacific. It could become the second Digital Dividend, in the EMEA region.  The Asia-Pacific Telecommunity (APT) has a harmonised band plan for MHz for Region 3 which was approved by ITU. As is the case with the APT band plan, 2 x 45 MHz of spectrum will be available.  The entire band, according to the APT plan, enables the use of 2 x 45 MHz for FDD operation. A TDD plan has also been defined.  The APT band plans include two duplexers associated with two separate 30 MHz duplex plans. The first is compatible with Europe (lower duplexer plan: and MHz) and the second (718–748 and 773–803 MHz) has already been selected by some Asian countries such as Japan.

10 1 GHz for high speed transmission  Out-of-band emissions could be different for PPDR networks / commercial networks due to specific needs (such as a limited number of devices, or protection from broadcasters).  The main hurdle with this option is that the mobile industry is cautious in trying to obtain additional spectrum below 700 MHz. ˃ Spectrum for PPDR networks? ˃ 2 x 10 MHz for PPDR networks below Figure: Extension of the APT band plan? The 700 MHz band: duplex gap and PPDR networks  The duplex gap defined in the 3GPP band plan (#28) represents 25 MHz of spectrum with use of the lower duplexer (10 MHz for the 2 x 45 MHz band plan). There are already candidate options for its use:  A supplemental downlink (SDL) option in order to use 20 MHz ( MHz) out of the 25 MHz of the duplex gap. This would provide additional downlink capacity for the 800 MHz band (3GPP #20).  Use for public protection and disaster relief networks -PPDR technical work is being undertaken by the FM 49 group of ECC (CEPT) in Europe; -Most European countries are currently in favour of using parts of the 700 MHz band or extensions of the 700 MHz band for PPDR applications. Some MENA countries, such as the UAE, have already adopted the 700 MHz band for PPDR.  TDD use of the duplex gap with the band being used for FDD. ˃ What applications for the duplex gap?

11 Spectrum sharing & new radio technologies

12 which normally use paired spectrum for uplink and downlink, supplemental downlink uses additional unpaired spectrum to enhance the downlink capability of mobile broadband networks. It has not yet been used in mobile networks; it is now possible with carrier aggregation technology. Carrier aggregation and supplemental downlink are included in HSPA+ and LTE-Advanced standards. ˃ Mobile operators around the world are currently looking into SDL as a solution to meet traffic demands: ˃ Being a further development of FDD networks Source: Qualcomm Figure: Principle of supplemental downlink  AT&T plans to use a supplemental downlink in its LTE network, aggregating 700 MHz unpaired spectrum with other paired spectrum on which it will deploy LTE. The US carrier expects to be able to deploy supplemental downlink as early as AT&T could also use the 700 MHz block it bought from Qualcomm with its AWS spectrum.  Orange France conducted trials in early 2013 in the French city of Toulouse. The mobile operator will use the L-band ( MHz) to provide mobile broadband systems with supplemental downlink capacity. The trial will use Ericsson base stations and devices employing Qualcomm chipsets. Both the base stations and the devices will use sup-plementary carrier frequencies in the L-band for downlink operations, combined with a traditional paired carrier at 2.1 GHz. Supplemental downlink (SDL) is bonded with the supplemental downlink channel(s) located in a different frequency band, to combine a single wider downlink channel as shown in the following figure. ˃ The usual downlink channel Growing very fast on mobile broadband networks – it increases traffic in the downlink. An asymmetric configuration with SDL serves to optimise traffic. ˃ This provides an answer to the asymmetric nature of multimedia traffic

13  “An individual licensed regime of a limited number of licensees in a frequency band, already allocated to one or more incumbent users, for which the additional users are allowed to use the spectrum (or part of the spectrum) in accordance with sharing rules included in the rights of use of spectrum granted to the licensees, thereby allowing all the licensees to provide a certain level of QoS.” (RSPG)  LSA could provide new harmonised spectrum for mobile broadband with predictable QoS guarantees. It could provide a solution to political, time and geographical constraints which occur with attempts to clear a new frequency band. ˃ Spectrum sharing is seen as one solution to spectrum congestion in Europe and in the USA ˃ Licensed shared access (LSA) is a new regulatory framework for sharing spectrum Spectrum sharing Figure: The ‘licensed shared access ‘ concept Table: Advantages and constraints of LSA AdvantagesRisks/constraints Allows more efficient use of spectrum: no change for the incumbent user of the spectrum and provides opportunities for new users/applications. Need for reliable sharing agreements between primary spectrum users and LSA licencees. New spectrum can be made available almost on a pan-European basis.A robust authorisation system must be built and has to be 100% reliable: it could be based upon a data base model in order to provide permanent updates on spectrum availability. Gives confidence to NRAs and spectrum managers as all LSA users are licenced. Need to manage the authorisation system. Compared with the licenced-exempt scheme, it provides more predictable conditions of use and almost allows them to provide the same quality of service as if primary users of the spectrum. Subject to negotiation with the incumbent user. Source: IDATE Source: Huawei

14 Impact of new radio technologies  New technologies such as ‘cognitive radio’ could well make new business models possible in the future. This can, though, only be expected to have a long-term impact: it will take years before cognitive radio technologies have established themselves significantly.  Cognitive radios see the first real implementation of ‘white spaces’ in the USA and the preparation of the regulatory framework in Europe. If they are successful, white space systems will only represent niche markets, given the numerous limitations to their implementation.  Spectrum aggregation will be a major improvement for mobile operators. It will enable higher data rates and the use of more spectrum in the downlink to adapt the mobile traffic structure. It also makes isolated frequency bands such as the L-Band more attractive to use.  LTE-Advanced is gaining momentum and will probably be implemented before TechnologyAdvantagesDrawbacksExpected development Heterogeneous Networks Enhanced coordination of macro and micro/pico layers Being included within 3GPP standards Cognitive radios - dynamic spectrum allocation Access to a dedicated spectrum band is managed through a database Administrative procedure have to be defined in relation to database management Cognitive radios - white spaces Maximise the use of spectrum: enables new users in underused bands Interference risksLikely limited deployment due to difficulties in finding business models Spectrum aggregation Enable the use of small portion of spectrum and/or downlink only chunk of spectrum More complex to implement and more frequency bands to manage Being included within 3GPP standards Already implemented in South Korea on LTE-A networks Source: IDATE

15 4G spectrum follow-up & licence valuation

16  The average quantity of spectrum per pop. is 2.06 (1.23 in 2009) MHz per million subscribers for the 5 operators analysed.  More potential spectrum in Western Europe: 700 MHz (second Digital Dividend), 3.5 GHz in the longer term. ˃ Outcome Source: IDATE Table: FDD spectrum assets for selected operators (September 2013) Comparison of frequency allocations of mobile operators

17  In the USA, the 700 MHz auctions held in 2008 reached an average value of 71 eurocents per MHz per pop. In Germany, the Digital Dividend spectrum was sold for 70 eurocents, in Sweden for 31 eurocents and in Spain for 54 eurocents.  800 MHz band: in France, with 70.4 eurocents per MHz per pop., the average price paid by the three ‘incumbent’ mobile operators is very close to the price paid in Germany in May 2010 (72.7 eurocents) but lower than in Italy in September 2011 (85.5 eurocents).  Australia 700 MHz: the 2013 auctions reached high valuation for the 700 MHz even though no block was sold. ˃ Price of premium spectrum Source: IDATE Figure: Price (eurocents) per MHz per pop. (for 10 years) 4G spectrum price: Digital Dividend, 700 MHz band

18  The 1800 MHz band is one of the most heavily-used frequency bands for LTE networks  In South Korea, the latest auctions for the 1800 MHz band reached a high valuation: KT paid million USD in September 2013 and SK Telecom paid million USD. ˃ Price of 1800 MHz spectrum Source: IDATE Figure: Price (eurocents) per MHz per pop. (for 10 years) 4G spectrum price: 1800 MHz band

19  The early references for assessing the cost of FDD 2.6 GHz spectrum in Western Europe were the auctions which took place in the four Nordic countries (Denmark, Finland, Norway and Sweden), the Netherlands and Germany. Subsequent auctions in France, Italy and Spain confirmed the initial trends.  Interest in, and valuation of, the 2.6 GHz band is expected to be higher in a few years from now, when lower frequency bands become saturated. The 2.6 GHz band will provide capacity in large cities. ˃ Price of 2.6 GHz spectrum Source: IDATE Figure: Price (eurocents) per MHz per pop. (for 10 years) 4G spectrum price: higher frequency bands

20  Valuation is very high for sub-1 GHz frequency bands due to their propagation characteristics.  The 2.1 GHz and the 1800 MHz bands are also valued at high levels due to their specific characteristics: -The 1800 MHz band can be rapidly used for LTE -The 2.1 GHz band is the ‘historic’ 3G band and will become a LTE band in Asia-Pacific and later in Europe ˃ Europe: valuation of the main FDD frequency bands Source: IDATE Spectrum price Frequency bandCurrent useFuture useValuation 700 MHzTV broadcastLTE MHzLTE MHzGSM/UMTSGSM/UMTS/LTE GHz (L-Band)No useLTE or HSPA supplemental downlink- to MHzGSMGSM/LTE GHzUMTSUMTS/LTE GHzLTE GHzWiMAXLTE-

22  Conditions associated with the use of the MHz band in Europe and neighbouring countries (principally in Africa, Russia and Ukraine).  Introduction and development of mobile broadband (MBB) and other advanced technologies.  Review and possible revision of the international regulatory framework for radiocommunications. Cognitive radios, software-defined radios (SDR) or short-range devices are proving to be disruptive technologies which can impose changes on the existing regulatory framework.  Management of satellite orbits and associated spectrum resources.  Scientific use of the spectrum. ˃ Main outcome ˃ Main items on the Conference agenda Source: IDATE, October 2013  A proposal from African and Middle Eastern countries for a ‘Second Digital Dividend’ was presented at the start of the conference.  The proposed allocation of the 700 MHz band ( MHz) to International Mobile Tele- communications (IMT), possibly quite similar to the first Digital Dividend in ITU Region 3 (Asia-Pacific MHz), initially faced opposition from CEPT countries.  An agreement was finally reached: the conditions for this new frequency band will be validated at WRC- 15, after technical studies. Lessons from the World Radiocommunication Conference (WRC-12)

23  The ‘white spaces’ concept enables of telecommunication services in underused frequency bands such as the VHF and UHF bands used for TV transmission. It involves cognitive radio techniques and enables opportunistic-sharing implementation between a primary user (incumbent) and a secondary one (new user). This approach cannot be considered as an off-the-shelf solution as commercial implementation is just starting on a limited basis in the USA and in the United Kingdom.  White spaces still at an early stage -Opportunity to use sparsely-occupied spectrum, attractive spectrum -But protection necessary for TV broadcasting and wireless microphones  Draft ECC report outlines rules for white space devices in Europe  Business models -Middle-mile model -Last-mile model -According to Microsoft, white space spectrum could generate between 3.9 billion USD and 7.3 billion USD in value annually over 15 years. ˃ USA - How to prevent interference Source: CEPT Figure: Principle of white spaces  The FCC technical conditions require that both fixed and portable devices include geo-location and spectrum- sensing applications which integrate with the FCC database of venues such as stadiums and concert arenas that use wireless microphones.  The database also holds TV signal propagation information.

24 Status of white spaces (2/2)  Due to the decisions taken at RRC-06 and WRC-07 relating to the use of the UHF band for broadcasting, the potential for white space spectrum availability is being gradually reduced. With digital broadcasting replacing analogue broadcasting and the associated re-planning of the UHF band across Europe, less white space spectrum is available now than previously under the analogue plan. The identification of the MHz band to mobile broadband has further reduced the potential spectrum for white space use.  We consider that white space technologies represent niche markets today and that they cannot be used to provide mobile service on a commercial basis in the UHF band. The concept could be extended to other frequency bands where sharing with incumbent users could be easier. Source: Spectrum Bridge

25  Digital Dividend: 700 and 800 MHz spectrum has the highest valuation today  1800 MHz: one of the most important bands for LTE  3.5 GHz: will see its valuation climbing with the development of LTE small cells ˃ Expected price for future auctions in developed markets Source: IDATE Past and expected spectrum prices

26  The FDD mode has been used since the start of digital mobile networks and is largely dominant worldwide. A more limited number of bands are defined for TDD operations.  Europe, Japan and the USA will share a limited number of common bands (such as around the IMT core bands) and regional differences are likely to remain. This will have a significant impact on LTE dongle and handset manufacturers. They will have to produce products covering different frequency bands for each market or produce more expensive devices covering multiple frequency bands.  As LTE commercial services open up around the world, more frequency bands are in use. The growing fragmentation of the LTE spectrum is complicating life for chipset manufacturers and is a negative factor in international roaming and for cost levels and LTE devices.  The main impact of this spectrum fragmentation is on international roaming. The selection of frequency bands in LTE devices is likely to be shaped by national constraints first. Regional harmonisation could follow.

28  US auctions in 2008  Part of the 700 MHz band is reserved for public safety  This plan is not compatible with the APT plan, and does not allow any compatibility or roaming for future LTE handsets. ˃ The US plan is not compatible with the APT band plan Figure: 700 MHz band plan in the USA The 700 MHz band: compatibility issues  The MHz portion would overlap between the 700 MHz APT plan and the Digital Dividend in Europe given a 3 MHz guard band in the upper part of the APT plan. ˃ There is an overlap between the upper part of the 700 MHz APT band and the lower part of the European 800 MHz plan Source: PSRC Figure: Overlap between 700 MHz APT band plan and 800 MHz band Source: NTRA

29  After postponing its auctions planned for November 2012 to a later date, the Australian Communications and Media Authority (ACMA) organised them for the 700 MHz (digital dividend) and 2.6 GHz bands auction in April/May  Auctions took place in May Telstra bought 2 x 20 MHz and Optus 2 x 10 MHz of 700 MHz spectrum. A 2 x 15 MHz block - one-third of the total – was not sold, probably due to high reserve prices. The third mobile operator in Australia, Vodafone Hutchison, declared that it did not need spectrum in the 700 MHz band to support its mobile broadband traffic in the years ahead.  Reserve price: 1.36 AUD/MHz/pop Source: ACMA Figure: 700 MHz band plan in Australia The 700 MHz band: Asia-Pacific

30  The MHz band is currently used in some Nordic and Eastern European countries by CDMA 2000 networks. These networks are likely to adopt LTE in the coming years. Brazil was the first country to allocate LTE licences in the 450 MHz band in  No rapid development is expected elsewhere in Western Europe as the spectrum is used by a number of private mobile radio networks. ˃ 700 MHz ˃ 450 MHz Source: Anatel Figure: 450 MHz spectrum in Brazil  See the Digital Dividend section for more details. New frequency bands (1/4)  The broadcasting part of the so-called L-Band MHz is currently being studied by CEPT, given that digital radio in this band has not taken off according to original plans.  At a multilateral CEPT meeting in Constanţa in 2007, a special arrangement was made to facilitate the introduction of terrestrial mobile multimedia services. It modifies the 2002 Maastricht agreement on the use of the band 1452– MHz for Terrestrial Digital Audio Broadcasting (T-DAB).  In early 2011, the ECC WG FM PT45 conducted a survey on the generic inventory of candidate applications for the MHz band. CEPT Report 018 to the European Commission responded to the Mandate on EU harmonisation of 1452– MHz (lower L-Band) to allow flexible use by mobile multimedia technologies.  Ericsson and Qualcomm (which bought the L-Band spectrum in the UK) commissioned an assessment of the net benefits of using the L-Band for a supplemental downlink (SDL) for the delivery of enhanced mobile multimedia and broadband services. ˃ L-Band: MHz Figure: L-Band: example of channel rasters Source: CEPT

31  The 2300 MHz band is already specified as a 3GPP band for both TD-SCDMA and LTE-TDD since LTE Release 8.  In some countries – Sweden is a case in point – the MHz band is considered as vacant, whereas in France it is used by the defence sector. It could be used for TD-LTE networks as there are already TD-LTE networks planned or launched around the world such as in Australia and India. ˃ 2.3 GHz band Source: Huawei Figure: 2300 MHz band allocations globally New frequency bands (2/4)  The Federal Communications Commission has adopted an order which enables mobile in 25 MHz of Wireless Communications Service (WCS) spectrum without causing harmful interference to the Satellite Digital Audio Radio Service (SDARS). ˃ USA Figure: The 2.3 GHz band in the USA Source: FCC

32  The MHz band is currently allocated to WiMAX operators in most European countries but there is very limited deployment of these networks and use across Europe. CEPT studied frequency arrangements in TDD and FDD modes for the MHz band and LTE is likely to be introduced in most European countries in the long term.  In February 2012, UK Broadband, a subsidiary of the Hong Kong PCCW, switched on a TD-LTE network in London, using spectrum in the 3.5 GHz and 3.6 GHz bands where it owns 124 MHz of spectrum. This is the first TD-LTE 3.5 GHz deployment in the world and the first commercial 4G deployment in the UK. It will operate a wholesale model, enabling partners to offer commercial services to businesses, consumers and the public sector from May 2012 onwards. ˃ GHz Source: ECC Figure: Harmonised frequency arrangements for the GHz bands  The GHz range has been identified for IMT in ITU Radio Regulations since World Radiocommunication Conference At its last plenary meeting in December 2011, the ECC adopted Decision ECC/ DEC/(11)06 on harmonised frequency arrangements for mobile/fixed communications networks (MFCN) in the bands MHz and MHz.  Based on CEPT Report 15, an EC Decision 2008/411/EC includes the specification of the least restrictive technical conditions. This Decision is binding for EU Member States and has to be transposed in national regulatory frameworks.  An earlier ECC Recommendation, ECC (04)05, defined the ‘Block Edge Masks’ (BEM) which restrict emissions in this band. The ECC decided to develop harmonised frequency arrangements for the high data rate mobile/fixed communications networks (MFCN), including IMT, utilising large channel bandwidths. New frequency bands (3/4)

33  2 GHz TDD -The TDD bands in the 2 GHz band ( and MHz) are currently being studied by CEPT. These bands were allocated in most European countries in the early 2000’s but are almost totally unused today. -Some mobile operators are pressing for paired spectrum in the 2 GHz band. One proposal is to pair the 1900–1920 MHz band with MHz or 2090–2110 MHz to extend mobile broadband services. The fact that licences have been granted in almost all European countries with different dates and that the spectrum is used in a limited number of countries constitutes a series of hurdles for regulators.  2 GHz MSS -Almost no use by satellite stakeholders ( and MHz) -Possible re-allocation to terrestrial use  GHz -This band is currently used by aeronautical radars. This frequency band could be identified during the WRC-15 conference for IMT use (mobile broadband).  GHz -Limited use is made of this frequency band in Europe by satellite systems. Parts of this band could be identified during the WRC-15 conference for IMT use (mobile broadband).  GHz -Little use is made of this frequency band in Europe by satellite systems. Parts of it could be identified during the WRC-15 conference for IMT use (mobile broadband). ˃ Potential new frequency bands for the long term in Europe New frequency bands (4/4)

34  The 3GPP standardisation group is working on LTE-Advanced, as part of Release 10. LTE- Advanced will be both backwards- and forwards- compatible with LTE, meaning LTE devices will operate in newer LTE-Advanced networks, and LTE- Advanced devices will operate in older LTE networks. 3GPP is studying the use of wider bandwidth support for up to 100 MHz via aggregation of 20 MHz blocks. This will enable very high data rates of more than 100 Mbps for mobility and 1 Gbps for nomadic use.  It should be noted that carrier aggregation can only be realised for the same duplexing method, thus FDD with FDD and TDD with TDD.
