Small Cells a Vital Part of Building a No-Edge Network Small Cells a Vital Part of Building a No-Edge Network Presentation Transcript

  • Small Cells a Vital Part of Building a No-Edge Network Xiangjun Zhang/George Zhao Huawei SmallCell Production Line 5 Nov. 2013
  • Trends
  • The Next Wave MBB, Everything on Wireless Everything on wireless, MBB is changing people’s life Connection (Bil.) Digitalization • People to people 50 Internet-formation • People to people • People to PC • 3 minutes/day online 40 30 20 10 1980 Mobilization • People to people • People to machine • M2M • 20 minutes / day online Intelligent • 7*24 online 95%+ connection on wireless People Things Data 10 million APP mobile internet user ratio: 50%+ 2020 1 million mobile APP 2013 iPhone launched 2011 Mobile user ratio: 2007 50% 1990 2000 2010 2020 2030 Resource: KPCB, comScore, IDC, Google, Apple, ITU
  • Mobile Network Transforming to Experience Oriented Voice business Coverage = Service Voice requirement = 12kbps Data business Experience = Service Normal video (240p) = 300kbps HD Video (1080p) = 5Mbps Operators Voted for important issue on MBB Network Others Source: Huawei user group meeting 2013, 300+ customers from 103 operators /organizations
  • Unbalanced Service Lead Challenges for Experience Sharp Capacity Demand in Hot Zone Tokyo Hotspot traffic will increase 2000~ 3000 times, in Tokyo, there’re more than 100 site per KM2 Indoor Takes Up 90% Data Traffic. Small cell will be 50 times more than Macro Voice Service 69.7% 30.3% Outdoor Data Service 90% 10% Outdoor Indoor In China, 60% traffic in 20% cell and 60% users in 20% cell 60% 60% traffic in 20% cell 40% 60% user in 20% cell Indoor
  • Traffic load ratio SmallCell+WiFi Co-Deployment to Capture Traffic on Hot Area A typical MBB network traffic load distribution ( Statistics 8000 Cells network) Hotspot Dense urban Urban / Sub-Urban 80% Traffic Rural scenarios 20% traffic SmallCell+WiFi LTE UMTS GSM Small+Wifi Co-deployment: Economical MBB Solution in valuable Hot Zone
  • SmallCell+Wi-Fi Complement Each Other for Better MBB Experience Spectrum and deployment decide quality of network Small Cell + Wi-Fi : 1+1>2 License spectrum Mobility Fetmo (Home) User deployed Small Cell (Hotspot + public) 5 4 3 2 1 0 Terminal QoS Operator controlled Wi-Fi (Home) Wi-Fi (Hotspot + Enterprise) Unlicensed spectrum Coverage Small Cell WiFi Capacity
  • Huawei SmallCell Solution
  • Main Concerns for SmallCell Outdoor Implementations 1. Installation: How SmallCell to Satisfy Complex and Comprehensive Site Scenarios? 2. Transmission: How to Provide Flexible Backhaul for Complex and Comprehensive Site Scenarios? 3. Experience: How to guarantee user experience among macro & micro, cellular & wifi?
