7 Telecomm evolution Source: Prepared by Alcatel Lucent based on data from Gartner, Ovum, Pyramid, Cisco, Yankee Group.. Data traffic on mobile networks will grow by a factor of 18 from 2011 to 2016 Video traffic will comprise 54% of total IP traffic by 2016 The number of terminals connected will be three times that of the global population One out of every seven persons will buy a new smart phone by 2016 The number of applications will grow tremendously

8 DoCoMo and KDDI to enable mobile video on TV (Source: Telegeography) 8 Jan 2013 The Japanese wireless operators NTT DoCoMo and KDDI have both unveiled new services which will allow subscribers to their respective mobile TV services to watch video and listen to music on conventional TV sets. Both firms plan to introduce a dongle which will enable wireless streaming from a smartphone to a TV via the home Wi-Fi network. (partially omitted) Separately, DoCoMo has also revealed plans to introduce a new dual-screen smartphone device from April, which will run on Android and feature two individual four-inch screens which can be viewed separately for multi-tasking applications or combined into a single six-inch display. The new device will be manufactured by NEC Casio Mobile Communications, The Nikkei writes.

13 Existing trends & challenges Multi-RAT Multi-layer Multi-vendor/component Exponentially growing demand for data Flat-lining average revenue per user/unit (ARPU) Increased competition and new players

14 Multi-RAT Several major wireless technologies exist As a result of conscious deployment Other aspects, such as: long-term spectrum license, large population of legacy UEs, etc It is already evident that none of them will be dominating in the near decade Each technology has its own niche and aims at slightly different goals: GSM: cheap, robust, is reliable for voice, is a candidate for M2M devices HSPA/HSPA+: is a de-facto major technology for the high-speed mobile access in urban and rural areas LTE: is well-suited for high-speed access in urban areas

20 MTS reveals 2012 rollout achievements (Source: Telegeography) 2 Jan 2013 Russian telecoms giant Mobile TeleSystems (MTS) has confirmed that during the twelve months ended 31 December 2012 it deployed a total of 6,000 GSM base transceiver stations (BTS) and 5,000 3G cell towers nationwide. In addition, the cellco rolled out some 2,000 LTE base stations in and around Moscow.

29 Multi-layered This is quite a vast umbrella term May assume a presence of several band/carriers An operator may deploy a service in several bands Each band comprises a number of carriers A UE does not support all the band/carrier combinations May assume a heterogeneous deployment Macro (also referred to as metro) Micro Out-door pico In-door femto

31 Femto cell deployments

32 Brazil s Vivo testing femtocells, aims to deploy in 2Q13 (Source: Telegeography) 10 Jan 2013 Brazilian mobile operator Vivo, a subsidiary of Telefonica of Spain, is carrying out trials of femtocell technology in the country, with a view to offering them commercially from the second quarter of Femtocell deployments have yet to happen in Brazil due to a lack of legislation, although a proposed bill that would clarify the rules on femtocells is under public discussion via Anatel until 25 January... In the meantime the pilot project will include 100 femtocells deployed to users who have expressed an interest in the technology, with about 80% of these small cells being installed in Sao Paulo.

33 Femto markets

34 Multi-vendor In case of the core/operator network: Different access points may be provided by different vendors Operators prefer not to lock themselves on a particular vendor So as not to mix equipment, a certain area is covered by equipment coming from the same vendor Different functional parts may be provided by different vendors The core network from vendor X The IMS/voice solution from vendor Y In case of the mobile user equipment Different components come from different vendors The wireless modem/chipset quite often comes from a different vendor

35 China Unicom selects W-CDMA vendors (Source: Telegeography) 28 Jan, 2009 According to The South China Post, five firms have won significant contracts from China Unicom in the tender for the deployment of W-CDMA infrastructure... Huawei, which has a partnership with Motorola, was the largest winner with a 30.6% share of the 70,000 base station deployment; Ericsson which partners Fiberhome Telecommunication Technologies and Guangzhou New Postcom Equipment won a 26.5% share; ZTE won 21.5%; Nokia Siemens Networks 11.1%; and Alcatel-Shanghai Bell 10.2%.

36 Factors driving mobile development Spectrum availability Achievable spectrum efficiency and maximum bit rates Install base Compliance Non-technical aspects

37 4G (and things we cater for)

38 4G (as per ITU-R definition) ITU-R has specified a set of requirements for the 4G system Officially called as IMT-Advanced Requirements are captured in a few documents: ITU-R M.2133 ITU-R M.2134

39 Some 4G requirements Based on an all-internet Protocol (IP) packet switched network Interoperability with existing wireless standards A nominal data rate of 100 Mbit/s while the client physically moves at high speeds relative to the station, and 1 Gbit/s while client and station are in relatively fixed positions. Dynamically share and use the network resources to support more simultaneous users per cell. Scalable channel bandwidth 5 20 MHz, optionally up to 40 MHz Peak link spectral efficiency of 15 bit/s/hz in the downlink, and 6.75 bit/s/hz in the uplink (meaning that 1 Gbit/s in the downlink should be possible over less than 67 MHz bandwidth) System spectral efficiency of up to 3 bit/s/hz/cell in the downlink and 2.25 bit/s/hz/cell for indoor usage Seamless connectivity and global roaming across multiple networks with smooth handovers Ability to offer high quality of service for multimedia support Source: IMT Advanced, Wikipedia

40 Peru bans use of 4G in marketing (Source: Telegeography) 28 Nov 2012 Peruvian telecoms regulator Osiptel has forbidden providers of mobile and fixed wireless services from using the terms 4G or Fourth Generation to market their products. The watchdog said its decision was based on the need to ensure accuracy and clarity of information that operators provide to users with regard to the qualities, properties and characteristics of products and plans a requirement under Peru s telecoms regulations. Osiptel noted that the term 4G, according to the International Telecommunication Union (ITU), denoted technologies with speeds substantially higher than those currently available in Peru. The regulator added that services currently offered under the name 4G were not materially different from those offered as 3G.

42 TIM, Vodafone, Wind granted 800MHz frequencies on schedule (Source: Telegeography) 7 Jan 2013 According to local press reports Italian cellular trio Telecom Italia Mobile (TIM), Vodafone Italy and Wind Telecomunicazioni (Wind Italy) have been granted Long Term Evolution (LTE)-suitable frequencies in the 800MHz band, as originally purchased in October The 800MHz spectrum, which was relinquished by a number of local television broadcasters by 31 December 2012, attracted the highest bids during the Ministero dello Sviluppo Economico s (MdSE s) 22-day auction, with prices ranging from EUR481.7 million (USD629.5 million) to EUR496.1 million per allocation.
