  1. 1. Small Cells and Femto Cells For Future Mobile BroadbandPIMRC – 21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communication Turkey – 28th Sep 2010 Dr Shahram G Niri Director of LTE/SAE Global Strategy & Solution – NEC Europe
  2. 2. Femto for Operators and End UsersThe Requirements Of Changing Industry Services will grow in multiplicity, diversity and richness  New services with the Internet at the heart the services New ecosystem & new player, new business and revenue models More powerful and enabled devices Users will grow in importance  Customer delight is absolutely essential  Adopting new habits (e.g. social media)  More demanding on the quality, interactivity, personalisation, Networks will grow in complexity Walled Garden will change to Open Networks High capacity pipes with intelligent plumbing Self managed and automated networks Relay Femto Communication delivered through SW on standards / generic HW Small Micro/Pico Macro Communication networks to improve in intelligence, flexibility, automation, resilience, efficiency, speed, security, privacy, latency YET lower delivery cost per bit/per sub/per sq kmPage 2Page 2
  3. 3. Diverged Traffic & Revenue Growth 50 Telecoms Price Development  From Kilo (103 ) bytes to Tera (1012 ) and Zeta (1021 ) 40 Mobile bytes Broadband  Global ubiquitous Internet-based solution with hyper 30 Euro/Month Connectivity  Hundred-fold increase in network flow brought by mass 20 terminals and mass digital content, and the thousand- fold, increase in traffic flow on mobile networks 10 0  Users are spending more time on the phone & internet 2002 2003 2004 2005 2006 2007 2008 2009  Average household spending on communication falls  Consumer pay less while getting better value -> they Traffic pay ~30% less than 5 years ago Complexity  Significant growth in traffic while slow in revenue  User experience at risk  What do we do with a surging traffic Gap  Is it a problem or an opportunity? Revenue Time Overall cost reduction is a very critical but not at the cost of compromising the service qualityPage 3
  4. 4. Innovation & Reform Towards More Sustainability Significant growth in traffic while slow in revenue Cost Vs Revenue does not add up User experience at risk Limit/control it (e.g. Cap in flat rate) Bring the cost of it down (e.g. More efficient deliveries in radio, transport and core network, Optimizations and other means of traffic handling Turn it to revenue (e.g. Innovative solutions, New revenue streams and sources) LTE Bigger, Smarter & Cheaper pipe Cheaper NW operation Higher performance Femto Intelligent Indoor Solution  New services & applications Cost saving and revenue generation Carrier Cloud  New service & revenue model  Service differentiation Cost optimization Lower cost & better performance and new revenue streams neededPage 4

  6. 6. Small Cells /Femto Cells Benefits  Better availability of high data rate Lower CAPEX due to saving in multimedia services site acquisition, installation and  Service bundling civil work Optimised Services  Faster data rates indoors where most of OPEX savings due to power, Deployment the data traffic exists site rental, operation manpower  Longer terminal battery life due to lower Build as you grow where the transmit power requirement investment needed  Fast LTE deployment Business  Last mile broadband solution  More capacity at reduced Performance  Target high revenue locations Opportunities cost per bit  New revenue streams (indoor)  Higher peak and cell edge  Location-specific tariffs and family performance contracts  Churn reduction Indoor / Outdoor deployment  Zero Touch, Plug&Play NO Site acquisition necessary Indoor / Outdoor One-Touch and Plug&Play operation deployment Fan Less and Air-Cooling Residential / SOHO Lowe power consumption Enterprise for indoor Commercial Power Adaptation private (AC/DC) Outdoor Public Small Cells and Femto cells are essential part of the future mobile broadbandPage 6
  7. 7. Femto for Operators and End Users Operators End Users Coverage improvements Better quality and availability, Capacity improvements Single handset & single subscription TCO reduction / optimisation Cheaper tariff /free calls Increased revenues (home zone and family tariff), •New market and new services Secure broadband mobile data •Reduce churn, improve quality and New services - Social Networking, Home encourage more usage voice & data networking, Presence, Content Sharing, • Increase customer loyalty, FMS The solution/ proposition different depending on:  Where you are (region/country),  Which operator (mobile/hybrid/ new player, small / large, …)  Which market (residential/ enterprise/various mobile broadband segments)  Existing investment in high speed mobile broadband  Cost saving on the capacity will depend on many factors A very efficient and cost effective solution for a true mobile broadbandPage 7
