  • Mobile Broadband – Threats and Opportunities Woojune Kim VP of Technology, Airvana Inc.
  • About Airvana • Established Supplier of 3G IP-RAN to Leading Operators – Founded: March 2000, over 500 employees worldwide – Over 60,000 EV-DO channel cards deployed at 70+ operators • Femtocell Pioneer & Technology Leader – Founding member of Femto Forum; Active contributor to 3GPP, 3GPP2 – Signed contract with Sprint (USA) and KDDI (Japan) for nationwide 3G rollouts – Multiple successful UMTS trials (2H’09) – Partnerships with leading network infrastructure and CPE vendors • Innovative, High Performance Femtocell Solutions – First femtocell to deliver 7.2 Mbps HSDPA (Jul’09) – First femtocell to deliver integrated router and ATA (Nov’09) – Only fully programmable 16-user femtocell; software upgradable to 24 user – First with standard Iuh based product – First with Robust Cell Reselection technology – Leading proponent of Open Services APIs that enable app ecosystem 2
  • Our Thesis • Mobile Data is growing Exponentially • Macro-cellular architecture cannot meet the long-term demands of mobile broadband • Transformation of cellular architecture through use of small cells is inevitable 3
  • The Background 4
  • Mobile Data Traffic is Growing Exponentially Mobile broadband explosion continues unabated. Smartphones are driving the industry and network usage. Services, services, services! 5
  • Air Interfaces Are @ Point of Diminishing Return Spectral Efficiency (bits per second per Hz) 3G Modulation Technology Evolution 4G Air Interfaces (LTE/WiMax) Will Deliver Modest Gains in Spectral Efficiency 6
  • Most Mobile Data Use Occurs Indoors Source: Informa’s Mobile Access at Home Report 7
  • But … In-Building Wireless Coverage is Poor Macro Network Internet 8
  • What Can We Do ? 9
  • The Solution : Spatial Re-Use 10
  • An Old Idea … 1Mbps Ethernet 100Mbps Ethernet Shared LAN (CSMA / CD) “Personal” Ethernet LAN 11
  • Femtocells : Spatial Re-Use in Cellular Networks Macro Cellular Femtocells Shared Base Station “Personal” Base Station • Coverage Gain: Better Signal Strength in the Home • Capacity Gain: Dedicated Capacity for Every Home 12
  • Realizing the “Personal” Base Stations Cellular For Existing Broadband Handsets Operator Internet Core Network Femto Cell • Small & Simple enough to put in Home • Connects through Broadband Internet • Support both Voice and Data 13
  • Significant Improvement in User Experience Femto Users Only Average User Throughput (Kbps) Macro Users Only Network Usage (Load) Consistent High-Throughput Data Performance 14
  • What about Wi-Fi ? For Dual Mode Broadband Handsets Operator Internet Core Network WiFi Access Point • Useful for Data Offload • But Not so Good for Voice (phone number, emergency calls ?) • Not available on all phones 15
  • The Key Technology Issues 16
  • Interference Avoidance & Mitigation Macrocell Handset Inside Femtocell Close or Near Femto Coverage to Macro BTS Macro Mobile Femto Mobile Macro Mobile Femto Mobile Femtocells With Overlapping Coverage Femto Mobile #1 Femto Mobile #2 17
  • Femtozone Applications • Femtocells as the center of the connected home – Aware of both mobile and home networks – Knows when user is home – Connects user to home from away Femtocell Apps enable Richer Mobile Apps 18
  • Application Example 1: SMS ~ Alert Me! Tom & Sally have arrived home from school 19
  • Application Example 2: Home Device Access 20
  • Summary 21
  • Femtocells : a Disruptive Proposition Consumer Operator • Improved Coverage • Radically Lower Costs • Wireline Voice Quality • Improved Customer Satisfaction • Superior Broadband Experience • Lower Churn • Lower Home Phone Costs • New Service Revenue • Innovative New Services • Strategic Presence in Home 22
  • Thank You Thank You 23
