In 2015, the key words of the Mobile World Congress were 5G, IoT, virtualization and LTE-U : PART 1

MWC infog

As for each edition, IDATE has been Analyst partner of the Mobile World Congress. A fantastic opportunity for our analysts and experts to interview many professionals coming from their Mobile planet to Barcelona for this intense and tremendous week.

5G Concept

Even though the concept of 5G is still very much under discussion (videos from KT, Huawei presented during conferences), NGMN (next generation mobile networks) Alliance published its 5G white paper which can be seen as the mobile operators “wish list” for 5G. Nonetheless, 5G is scheduled for 2020. Early trials should arrive in 2018, with projects scheduled for the Winter Olympic games in South Korea (4G became real in 2010’s, 3G in 2000’s). Key advantages of 5G over 4G would be a much lower latency (1ms compared to 40 ms in 4G and 100 ms with 3G), the capacity to connect billions of devices, faster response that will boost services like augmented reality, self driving cars and online gaming. Huawei mentioned that 5G should reach 10 Gbps (7 minutes to download a movie with 4G, 6 s with 5G).

5G should better take into account specific requests of vertical markets (healthcare, automotive, energy, government, city management, manufacturing and public transportation) and better manage the Internet of Things.

Equipment suppliers showed first demos of 5G air interface using millimetric bands (70 GHz - Nokia) and 15 GHz (Ericsson). New air interface techniques were proposed by Huawei with the non-orthogonal access technology based on Sparse Code Multiple Access (SCMA), and Filtered-Orthogonal Frequency Division Multiplexing (F-OFDM).

With tvisuel principal idate MWC v2he 5GPPP (Public Private Partnership), Europe is trying to accelerate developments of 5G with fundings of €700 million for R&D. It is expected that the industry will invest five times this amount. According to the 5GPPP, 5G should be based upon a HetNet (heterogeneous network) supporting various radio access technologies and frequency bands ranging from sub-1 GHz bands to 100 GHz. Various traffic profiles will have to be supported:

 

•    Low speed-low energy for IoT sensors
•    High speeds for video services
•    Very low latency profile for mission critical services such as PPDR (Public Protection and Disaster Relief) and for transportation issues

Google will soon become a MVNO

Google confirmed during the MWC that the group is negotiating MVNO agreements with the US mobile operators. Light details on Google plans so far. Further information scheduled for months to come. Nova is not expected to compete directly against US MNOs. In addition, Google do not want to launch a network at scale.
The Google MVNO will only work with the Nexus6. “The focus of Google’s network could be on connecting devices other than phones, as watches, cars and other devices increasingly will include mobile connectivity features”.Mobile Identity

Different methods of identification and authentication, each suited to particular transaction types (from access to social network to official ID) ; biometric authentication as a new solution.
•    Digital identity card exists in Estonia (with digital authentication), biometric card exists in middle east and Africa (Algeria, South Africa)
•    Mobile authentication is a challenge for mobile operators, but the market is far from mass-market: demand is not ready for official ID authentication on mobile, standards are needed, as well as regulation.Mobile Id could be a leapfrog technology in emerging countries where people don’t even have identity papers, and have a mobile phone.
If mobile operators don’t manage to be positioned on this market, banks or social networks could.

Virtualization

PICTO VIRTUANetwork Function Virtualization (NFV) appeared last year during MWC and is now close to commercial implementation by mobile operators. Telefonica demonstrated a full network together with ALU and HP. It will integrate a vRAN, vCDN, vEPC and vIMS.
A first implementation of vRAN was presented by China Mobile which is collaborating with Alcatel-Lucent and Intel on Cloud-RAN, which is seen as a first step towards virtual RAN. NTT Docomo is working with NEC on virtualization of the core network (EPC).

LTE-U

LTELOGO2LTE-U technology is important and was present on many vendors’ booths. It will give free access to additional spectrum in the 5 GHz band currently used by Wifi. This will provide SDL (supplementary downlink) capability, providing extra capacity for downlink traffic, especially video. LBT (Listen Before Talk), the specific function which will allow smooth compatibility between Wifi and LTE in the 5 GHz band will be included in 3GPP Release 13 expected to be adopted in Q3 2016.
LTE and Wifi carriers can also be combined in order to provide higher throughputs but in that case, the benefits of LTE higher spectrum efficiency are not present.

DTT in emerging countries : Can spectrum sales finance the digital transition?

Jacques Bajon

 

Jacques Bajon, Head of "Video Distribution" Practice

In developing countries and emerging economies, wireless broadband represents a fundamental path to eradicating the digital divide that exists in regions that are still not covered by wireline infrastructure, and especially sparsely populated rural areas.

The digital switchover of terrestrial networks and the associated digital dividend provide a unique opportunity for broadcasters to expand their services, for consumers to gain access to a broader selection of programming, for the market to meet the growing demand for new wireless communications services, and for governments to optimise the overall use that is made of the scarce resource that radio spectrum represents. All for the sake of socioeconomic progress. In developing countries and emerging economies, wireless broadband represents a fundamental path to eradicating the digital divide that exists in regions that are still not covered by wireline infrastructure, and especially sparsely populated rural areas.

Is integrated broadcast-broadband the answer?

Despite the existence of several international agreements, the transition process is not progressing at an even pace across the global. New arrivals to the process are up against tremendous challenges, while also benefitting from the experience of their predecessors and technological leaps forward – such as the combination of DVB-T2 and MPEG-4 – which help alleviate some of the hurdles. Key ingredients of successful planning include consideration of the national situation, along with clear policies and objectives from the government and real cooperation between the various stakeholders.
It is a well-known fact that the digital dividend is a driving force between the transition, but new questions have arisen recently over a second digital dividend in the 700 MHz band in Region 1 (i.e. Europe, Africa and the Middle East). So the telecommunications and media industries will need to cooperate more closely on the spectrum issue.

The digital transition: global scorecard

A global economic approach needs to be taken in the planning stage to tackle the goals of the transition, and the means being deployed to achieve them.
In developing countries where the switch to digital terrestrial television (DTT) has yet to begin, digital set-top boxes represent the biggest cost item. A large percentage of households in these countries will need to receive subsidies to be able to buy these new devices.
Additionally, the size of the network investment will depend on several factors, such as the number of multiplexes involved. By the same token, technical coverage will need to be adapted to each country according to the geographical distribution of its citizens, as costs can increase exponentially when seeking to cover a large swathe of the population.
Communication campaigns are also vital, to educate the public on the digital transition. They need to be rolled out gradually, and be especially concentrated during the period immediately prior to the transition from one technology to the next.
In addition to financing set-top boxes and running information campaigns promoting the transition to digital, public monies may be required to help TV channels during the transitional phase. The period of simulcasting will be one of additional broadcasting expenses that will not necessarily be compensated by revenue and, for incumbent channels, will also be a time of increased competition. Veteran broadcasters will have to upgrade all of their equipment and installations when the switchover occurs.
The revenue earned on the sale of licences to digital dividend spectrum can help meet the public financing needs created by the transition. It is vital that a global approach to the process be taken – one that involves both the television and telecoms universe. These two sectors can enter into a mutually beneficial virtuous circle.
Public-private partnerships to allocate digital dividend revenue to the transition
Governments need to be financially involved in DTT rollouts, and in the transition process as a whole. The economic surplus generated by a better allocation of frequencies and related services creates solid prospects for ROI in the medium term.
The digital switchover is thus an ideal opportunity to create public-private partnerships. The foundations are already in place, with the arrival of new private sector players from the world of both telecommunications and broadcasting.

LTE-Advanced will represent 30-40% of the total LTE subscriber base at the end of 2017

LTE networks in operation today mainly use LTE Release 8 of the 3GPP standard. LTE-Advanced (Release 10) brings many technological innovations which enable higher data rates on both the uplink and the downlink and deliver better performance at the cell edge:

  • LTE-Advanced (LTE-A) enables higher data rates: theoretically, 150 Mbps on the downlink and as high as 3 Gbps in the years ahead. An uplink maximum of 1.5 Gbps will be possible.
  • LTE-Advanced brings many enhancements to LTE networks. LTE operators can ‘pick and choose’ the functionalities such as carrier aggregation, enhanced Inter-Cell Interference Coordination (eICIC), HetNets and enhanced MIMO.
    • Carrier aggregation: a total up to 100 MHz bandwidth can be aggregated with a maximum of five component carriers. This will enable higher user peak throughput.
    • Heterogeneous Networks (HetNets): LTE-A enables operators to deploy low-power small-cells in addition to macrocells in the same channel.
    • Enhanced MIMO: up to eight multiplexed layers for downlink and up to four multiplexed layers for uplink.
    • Relay function.
    • Spectrum efficiency: 1.4 to 1.6 times better than on LTE Release 8.
  • LTE-Advanced compatible smartphones were launched in Q2 2013 by Samsung and LG.Apple is expected to follow in H2 2013 or early 2014.

The first LTE-Advanced networks were launched in early H2 2013 and the mass market for LTE-Advanced is expected to have taken shape by 2014-2015. USA, South Korea and Japan are currently the front runners regarding LTE-Advanced implementation. The leaders in LTE-Advanced deployment are South Korean operators, headed by SKT and LG U+. Actually SK Telecom places much emphasis on carrier aggregation but many other players in the industry indicate that higher-order MIMO and HetNets are also key elements in LTE Advanced.On 26 June 2013, SK Telecom, the pioneer in LTE-Advanced, launched its LTE-A services in parallel with the Samsung Galaxy S4 LTE-A enabled version. At the end of July 2013, SK Telecom reported 300,000 LTE-Advanced subscribers in South Korea, out of a total LTE base of 11 million.

Roadmap of LTE-Advanced implementations

The LTE-Advanced market will soon follow in opening in Japan and the USA. New markets will open in 2014 and mass adoption will start in 2015. We forecast that LTE-Advanced will represent 30-40% of the total LTE subscriber base at the end of 2017 and should reach a half-billion LTE-Advanced subscriptions worldwide.

Interview with Gilles BRÉGANT, CEO of ANFR

Published in COMMUNICATIONS & STRATEGIES No. 90, 2nd Quarter 2013

The radio spectrum: A shift in paradigms?

Summary of this issue: Demand for the use of the radio spectrum is constantly and rapidly growing, not only as a means of carrying Internet traffic, but also for new or expanding use by the military, public protection and disaster relief, at the same time that more traditional applications such as aeronautical, maritime, and radio astronomy remain. Is spectrum policy entering a trackless wilderness, or can a new direction and a new set of paradigms be expected to emerge? The contributions to this special issue of Communications & Strategies cover a great deal of ground. They serve to provide valuable signposts for spectrum policy going forward.

Gilles BRÉGANT CEO of ANFR

Exclusive:
Interview with Gilles BRÉGANT
CEO of ANFR.
(French national spectrum agency)

Conducted by Frédéric PUJOL,

Head of the radio technologies & spectrum practice, IDATE

 

C&S: What are ANFR's main priorities in the coming two years as far as Spectrum management is concerned?

Gilles BRÉGANT:

The Agence nationale des Fréquences (ANFR) is the French public Agency in charge of radio spectrum management. It is placed under the jurisdiction of the Minister responsible for Electronic Communications (Mr. Arnaud Montebourg and Ms. Fleur Pellerin since May 2012) but all the Ministries using spectrum are represented at ANFR's board. Besides, ANFR's decisions regarding spectrum allocation are actually taken by the Prime Minister since spectrum, in France, is a state affair.
Spectrum management priorities will be closely linked to the governmental decisions and digital economy needs for the following years and to the international and European agenda.

A. Create the conditions of mobile broadband (4G) success in France
4G allows very high data flow rates and significantly increased user comfort: lightning-fast downloads, and a more fluid navigation become possible on smartphones or tablets. This opens up opportunities for new services in mobility, such as access to audiovisual content. A factor of innovation, growth and job creation, 4G is one of the priorities of the Government. ANFR has been deeply involved for the development of European harmonized conditions for the usage of 4G and is currently mobilized to make a success for the introduction of this new technology.

Since December 2012, the Agency has published a 4G roll out observatory. This tool will be key to monitor 4G infrastructures deployment, carrier by carrier.
However, the 4G challenge will be a tricky one when it comes to spectrum management since the 800 MHz 4G can interfere with DTT. ANFR uses its resources devoted to the protection of TV reception so that the 4G 800 MHz and TNT coexist harmoniously.

The ANFR intervenes at every stage of the deployment:
- it actively participates in the communication towards local elected officials, professionals and the general public on these operations;
- during the phases of deployment, it collects and instructs the claims of viewers through its call center;
- it oversees the resolution of the problem by operators if the interference comes from the 4G 800 MHz. A professional intervenes, most often to insert a filter in the reception of the TNT facility.
The TV reception is therefore guaranteed for each viewer. The full cost of interventions is supported by mobile operators.

B. Prepare the next World Radiocommunication Conference (WRC)
In 2012, we have drawn the immediate consequences of the WRC-12. In 2014, the delegations will develop first arbitrations of WRC-15. In 2013, national positions must be taken.

One of the challenges of this Conference will be the question of the future of the 700 MHz band. In France, it is now assigned to audiovisual. Since the debates on the first digital dividend, five years ago, the terms of the problem have been well known: the use of mobile Internet is expected to grow regularly in the coming years to meet the expectations of very mobile broadband. But this demand for broadband is common to all sectors: the audiovisual sector wants to keep these frequencies to offer new services: generalization of high definition, introduction of ultra high definition or 4K for example. And Government services, such as those of the Ministry of the Interior, also want to access services such as video for safety services.

In this debate, three ideas seem inevitable:
- there is not enough spectrum available under 1 GHz to satisfy fully each need;
- France is not an island, and it will have to act in harmony with its Western European neighbors;
- Europe will have to play an important role.

ANFR, as it manages the entire spectrum and guaranties technical neutrality, is coordinating the preparatory work at the national and international levels. ANFR, which is already contributing to the preparation of the next WRC, is involved in various entities in CEPT and UIT involved in this process and is bringing its technical expertise to the Government so that a decision can be taken in the best conditions.
ANFR is also an active member of the RSPG ad hoc group, which will provide recommendation to European Commission on WRC issues and on the identification of 1200 MHz for wireless broadband.

C. Facilitate the deployment of the 6 new DTT channels
Since December 12, 2012, 25% of the French population can access 6 new HD channels with their DTT HD TV sets. Free to air TV is no longer limited to generalist channels. Every French citizen, and not only the ones with cable, satellite or IPTV subscriptions, will be able to watch specialized channels on areas such as sports, travels, diversity and so on by 2015.

The years to come will see more of the French population covered by the new HD DTT channels.
The Agency, together with the CSA, has the mission to assist viewers in solving their TV reception problems through its call center and its dedicated website, "www.recevoirlatnt.fr", in collaboration with local aerial installers. If necessary, it will grant funding provided by the State to viewers who have lost DTT reception.

What are the expected evolutions as far as new ways of sharing spectrum are concerned? What are their consequences on spectrum management?

First, it is important to recall that spectrum sharing is already a reality with short range devices operating under a general authorization on a non interference and non protection basis. This is the case for Wifi in the 2.45 GHz and 5 GHz bands. This is also the case of all applications using ultra wide band devices which are sharing spectrum thanks to a very low power density. UWB technology was also used in sectors such as automobile and aeronautics.

What about Licensed Shared Access (LSA)?

The objective of an LSA approach is to facilitate the introduction of additional users operating with individual spectrum rights of use in specific bands and on a shared basis with an incumbent user, thus allowing predictable quality of service for all rights holders. These arrangements will need sufficient flexibility in order to account for national particularities, in relation to the administration of spectrum.

LSA could be introduced as a regulatory approach to release spectrum. In addition to conventional planning methods, cognitive radio technologies and their capabilities (geolocation databases, sensing, etc.) could be taken into account as enablers for sharing under the LSA approach.

ANFR engineers are actively participating in European works, at the ECC level for instance, on this issue, which is still in its early stages.

700 MHz band: what are the stakes and constraints?

World Radiocommunication Conference (WRC) 2012 decided that for the Region 1 the 694-790 MHz band will be allocated to mobile service co primary with broadcast services, this allocation becoming effective after WRC-15.

The issues at stake in the preparatory works for the WRC-15 are each tied to technical and negotiated matters. The possible refinement of the lower band edge (694 MHz) is one issue up for debate during the preparatory works. The second stake is the identification of a harmonized channelling arrangement, that is to say, the uplink and downlink bands. Finally, technical matters such as sharing studies between mobile and DTT at 694 MHz and the consequence of this on the necessary guard band are also to be clarified through the preparatory works for the WRC-15.

Regarding the choice, and its consequences, between IMT and broadcast, WRC was the starting point. The next steps are European decisions and national arbitrages.

2013 will be the year of public exposure to electromagnetic fields in France (ANSES report, Abeille Bill…): what is the role of ANFR as far as exposition control is concerned?

First, the Agency has no sanitary or health prerogatives, its expertise and missions only rely on technical matters.
The Agency monitors the respect by radiocommunication network operators of the public exposure to electromagnetic fields limits. The legal limits are the ones of a 1999 European Recommendation. Besides, by Law, the Agency has to make an inventory of "atypical" points, that is, the points where the exposure is significantly above the national average (while still below the limits). ANFR also elaborates the protocol used to measure the public exposure to electromagnetic fields. ANFR is also in charge of devices monitoring (phones, smartphones, tablets…). We insure that DAS limits (2 W/kg) are respected. We also check if the necessary information is properly provided to consumers.

2013 will indeed be the year of public exposure to electromagnetic fields. It began with the Bill introduced by MP Ms. Abeille from the Environmentalist Party. This Bill was forwarded to the Parliament Economic Commission for further analysis.
In 2013, we will publish our report on technical experiments which were lead in France to assess the possibility to reduce public exposure to electromagnetic fields due to mobile operators antennae without decreasing coverage and quality of service. Such experiment is a world premiere until now. 2013 will also be the year when ANSES, the French sanitary authorities, publishes its new report on the sanitary effects of such a field.

The Agency is a neutral, technical expert in that area. By participating in public meetings, advising elected officials and also the general public through its website Cartoradio, the Agency participates in turning this potential concern into a serene public debate. Finally, in 2013 we will provide a mobile version of Cartoradio, with the location of all mobile based-stations and the results of more than 26,000 field measures.

The ANFR organizes an international Conference on June 26 and 27 2013 entitled "Spectrum & Innovation": what is it about?

The Conference "Spectrum and Innovation" was instigated by Ms. Fleur Pellerin, delegated Minister in charge of Small businesses, Innovation and Digital Economy. We want the Conference to be a major event in 2013 for the digital economy sector in general and radiofrequencies in particular. The objective is to show to a large audience of professionals from the digital economy how spectrum is key to their sector and how this resource is crucial to economic growth in the coming years.

Different themes will be dealt with: how mobility is shaping our society and stimulating innovation, how radiofrequencies constitute a growth leverage for industry and small businesses, or even the spectrum needs for 2020. To debate on these subjects only experts in their fields have been chosen. The Conference will also be a chance to listen to influential and renowned speakers: Ministers, European and foreign institutions officials, renowned academics and business leaders (BBC, Bouygues Telecom, Cisco, Eutelsat, France Télévisions, Free Mobile, IBM, M6, NRJ Group, Orange, Qualcomm, Renault, SFR, TDF, TF1…).

We expect these two days to shows us what exciting new developments can be in store in the coming years. The Conference will prove how spectrum can foster innovation, growth and job creation.

Global LTE forecasts : 830 million subscribers expected in 2016

Frederic PUJOL

Radio Technologies & Spectrum Practice Manager - IDATE

27 February 2012, Barcelona, Spain – IDATE provides regular analyses of the main trends shaping the world’s mobile markets: networks, devices and services. DigiWorld by IDATE have teamed up to publish the new edition of its special White Paper: “LTE 2012 - Markets & Trends” to coincide with the Mobile World Congress in Barcelona (27 February-1 March 2012).

The first commercial LTE rollouts and the main operators’ strategies are forging the trends that will shape the LTE market’s development in the years ahead:

  • LTE is being implemented mainly to supply added capacity, but  some operators are using it as a way to distinguish themselves from the competition
  • LTE is also driving costs down for mobile operators
  • LTE will dominate 4G: the LTE ecosystem is trimming the mobile WiMAX market
  • The lack of LTE-compatible devices (2.6 GHz band) is currently an issue in Western Europe
  • Spectrum fragmentation for LTE is slowing down roaming prospects
  • The scarcity of digital dividend spectrum and the drive for sustainable business models in certain developing markets will drive a greater degree of network sharing
  • Voice (VoLTE) is chiefly a long-term concern for most operators
  • LTE femtocells will play a key role in LTE deployments
  • LTE-Advanced will roll out sooner than expected: the first real-scale deployments due in 2013, instead of the previous target of 2015
  • TD-LTE is now seen as a complement to LTE FDD in many countries
  • LTE in the digital dividend can provide a substitute to the fixed network – as seen in Germany, Australia and as planned by Verizon Wireless
  • LTE wholesale model developing worldwide with many implementations around the world

At the end of 2011, there were approximately 9 million LTE subscribers worldwide according to our LTE Watch Service database. More than 60% of LTE subscribers were in the US as of 31 December 2011, with Verizon Wireless accounting for close to 90% of them.

We forecast that, by the end of 2015, there will be more than 482 million LTE subscriptions worldwide. Of these, Asia-Pacific will represent 34.3%, North America 28.9% and Western Europe 17.9%.

We anticipate that mobile traffic will reach more than 127 EB in 2020, representing a 33-fold increase compared to 2010. By 2020, Asia will represent 34.3% of total mobile traffic, followed by Europe (22%) and the Americas (21.4%).
