What is the Key Challenge Facing the Wireless Market Today?

In the smart phone era, traditional large cell sites are challenged to deliver on customer demand in densely populated, urban locations.
![Page 5: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/5.jpg)
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
![Page 6: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/6.jpg)
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.

What is the Solution?
![Page 8: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/8.jpg)
![Page 9: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/9.jpg)
What is a Distributed Antenna System (DAS) & Small Cell Network?
![Page 10: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/10.jpg)
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.
![Page 11: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/11.jpg)
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.
![Page 12: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/12.jpg)
• 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
![Page 13: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/13.jpg)
Example: 1 Macro Tower has the capacity for only 72 cell phones covering 1 square mile
![Page 14: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/14.jpg)
In Comparison:
6 strategically placed DAS sites have the capacity for 432 cell phones covering 1 square mile

How Does DAS Technology Work?
![Page 16: 10 Things You Need to Know about DAS Small Cell Networks](https://reader033.fdocuments.us/reader033/viewer/2022052906/558d3940d8b42a74688b45a3/html5/thumbnails/16.jpg)
• 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

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.

• 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”

How much mobile data did Super Bowl 2014 attendees consume?

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.

60% Figures were up from the previous year (as more people
move to smartphones, and those having them use more data), but the rate of growth might be a little shocking: in 2013, AT&T only measured 388GB during the game, meaning 2014’s event saw 60% higher usage.
