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.
