10 Things You Need to Know about DAS Small Cell Networks

  1. 1. 10 Things You Need to Know About DAS/Small Cell Networks
  2. 2. What is the Key Challenge Facing the Wireless Market Today?
  3. 3. In the smart phone era, traditional large cell sites are challenged to deliver on customer demand in densely populated, urban locations.
  4. 4. Over 200 Million Americans now use cell phones* and more stress is being put on wireless networks to deliver data to their customers. * Based on a study by the Pew Research Center
  5. 5. The explosive growth in wireless data usage has placed capacity burdens on the traditional large (macro) cell site capacity, where every cell phone is competing for bandwidth, leading to spectrum congestion and poor quality of service.
  6. 6. What is the Solution?
  7. 7. What is a Distributed Antenna System (DAS) & Small Cell Network?
  8. 8. DAS & Small Cell Networks provide similar wireless capacity over much smaller areas, dramatically increasing the capacity of the overall system, especially in areas of highly concentrated users.
  9. 9. Increased capacity relies on the placement of large numbers of small radio stations with small coverage areas. To meet consumers’ service expectations, these systems need to perform even during power outages, therefore, uninterrupted power supply is critical.
  10. 10. • Provides reliable coverage in targeted locations • Provides much needed increase in voice and data capacity • Is similar to mini-cell towers – covering more people over a smaller area
  11. 11. Example: 1 Macro Tower has the capacity for only 72 cell phones covering 1 square mile
  12. 12. In Comparison: 6 strategically placed DAS sites have the capacity for 432 cell phones covering 1 square mile
  13. 13. How Does DAS Technology Work?
  14. 14. • Central Power (what GE provides) is delivered to remote Communication Nodes, which sends signals out to areas with a high density of users • The nodes then send a signal back to the central communications hub via fiber optic cable RRU RRU RRU RRU Main Unit RRU Optical Cable In the event of power failure, GE recommends uninterruptible power be provided to DAS units at -48Vdc, typically via a backup battery system with remote monitoring capabilities.
  15. 15. How Does Small Cell Technology Work?
  16. 16. • Distributed Power (what GE provides) is placed in each Individual Node, which sends signals out to areas with a high density of users • The Nodes connect back to the central communications hub via fiber optic cable • Each cell is “all-encompassing” In the event of power failure, GE recommends uninterruptible power be provided to Small Cell units at -48Vdc, typically via a backup battery system with remote monitoring capabilities.
  17. 17. What are the Key Differences Between DAS & Small Cell?
  18. 18. DAS One central power supply, powering multiple nodes Scalable Multiple frequencies (2G, 3G, 4G, LTE, VHF Bands) Can support multiple service providers Design intensive, network planning High up-front costs
  19. 19. Small Cell Individual power supplies in each node (typically) Faster deployment Less design-intensive Supports one service provider Lower up-front costs
  20. 20. DAS & Small Cell Networks Who & What Benefits?
  21. 21. We are seeing a trend in LATAM, where telecom providers are skipping the development of Macro Sites in favor of deploying DAS/Small Cell.

  33. 33. How much mobile data did Super Bowl 2014 attendees consume?
  34. 34. AT&T prepared in advance for the onslaught its network would experience from all those fans snapping photos, posting status updates and checking stats by augmenting coverage with a DAS system, and publicly shared some of the specifics behind just how much data football fans consumed at this year’s Superbowl.
