Successfully Integrating Small Cells into the Network

  1. 1. Successfully Integrating Small Cells into the Network Alejandro Ferrer, Senior Strategy Consultant Broadband World Forum Amsterdam, 22 October 2013 Broadband World Forum 2013 | © Ericsson AB 2013 | 2013-10-22 | Page 1
  2. 2. Small cell objectives Today’s challenges WHAT? WHERE? Time to Market (TTM) Coverage? Suburban Dense Urban Capacity? Residential Enterprise Mall/Convention Venue Quality? Broadband World Forum 2013 | © Ericsson AB 2013 | 2013-10-22 | Page 2 HOW? Total Cost of Ownership (TCO)
  3. 3. Ready to deploy…but where do I begin? Broadband World Forum 2013 | © Ericsson AB 2013 | 2013-10-22 | Page 3
  4. 4. HN & Small Cell Modeling 3D models of existing cities to ensure accurate results Broadband World Forum 2013 | © Ericsson AB 2013 | 2013-10-22 | Page 4
  5. 5. Identify solutions for your network expansion Increasing DL capacity GB/User 20 16 12 8 4 0 Baseline (10 MHz 2X2) 10 MHz => 20 MHz 2X2 => 2X4 2X2 => 4X4 Increase bandwidth and antennas Broadband World Forum 2013 | © Ericsson AB 2013 | 2013-10-22 | Page 5 Doubling number of macro sites 12 LPNs/macr o Increase number of sites Baseline, 20 MHz, 4X4, doubling of macro sites +6 LPNs/site Baseline, 20 MHz, 4X4, doubling of macro sites Combination of efforts
  6. 6. Small cell planning Identify Define options and select solution Coverage? CM/SI Transport Capacity? Issues Requirements Quality? Broadband World Forum 2013 | © Ericsson AB 2013 | 2013-10-22 | Page 6 Deploy and integrate small cells
  7. 7. Geolocation to improve accuracy Clutter info Prediction + PM Network Geo-data (Parsed GPEH) Drive Test Social media Broadband World Forum 2013 | © Ericsson AB 2013 | 2013-10-22 | Page 7 HN Geolocation
  8. 8. Design for small cells a sophisticated process Traffic density TCO for each location/solution Coverage holes Capacity bottlenecks Dominance/geometry Available power/transport Small cell locations & solutions Adjustable Optimization technology (field-proven) Best solution by understanding all possibilities and constraints Broadband World Forum 2013 | © Ericsson AB 2013 | 2013-10-22 | Page 8
  9. 9. Where is the small cell? Broadband World Forum 2013 | © Ericsson AB 2013 | 2013-10-22 | Page 9
