6. Qualcomm – Crown Castle Small-Cell Trial Summary • Small cells improved system capacity • The new small cells increased the number of sectors in the system by 29% and covered only 18% of the geographic area but increased the total system forward-link throughput by 61%. • Small cells can effectively offload traffic in all coverage scenarios • The small cell placed directly below a much higher power macro sector effectively offloaded traffic and created its own unique dominance region. • Excessive soft handoff was not observed at either of the small cells • Throughput within the coverage areas created by both small cells increase significantly • Small cells can improve in-building performance, even in areas with dense macro coverage • The small cell broadcasting near the street level improved in-building throughput and coverage even though there was strong existing coverage from a macro sector.

7. Overview of the DAS Forum • Mission: • The DAS Forum (a membership section of PCIA—The Wireless Infrastructure Association) is a broad-based organization dedicated to the development of the distributed antenna system (DAS) component of the nation’s wireless network. • About The DAS Forum: • Founded in 2006, The DAS Forum is the only national network of leaders focused exclusively on shaping the future of DAS as a viable complement to traditional macro cell sites and a solution to the deployment of wireless services in challenging environments. • DAS Forum members own and manage all of the neutral host and many of the carrier-owned outdoor DAS installations in the U.S. • The DAS Forum’s membership includes all of the major outdoor DAS infrastructure providers, as well as major carriers, equipment manufacturers, and professional services firms.

9. What is DAS? A distributed antenna system (DAS) is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure. DAS antenna elevations are generally at or below the clutter level of nearby trees and buildings.

10. Benefits of DAS • Coverage: DAS architecture provides coverage in areas that cannot be effectively addressed with traditional sites. • Capacity: DAS can closely align capacity to actual market requirements, managing available radio resources. • Spectrum: DAS uses available frequency spectrum efficiently through multiple low-power transmission points. • Interference: DAS reduces interference through low radiation centers and lower output power. • Data: DAS provides better data throughput given signal strength and proximity of transmission points to user equipment. • Scalability: DAS is a scalable network that can meet future capacity requirements, or additional carriers, by adding additional nodes. • Adaptability: DAS can respond to market dynamics, equipment architecture changes and new technologies.

11. DAS Drivers • Healthcare: • 78% of Americans expressed interest in mobile health(Harris Interactive & CTIA) • By 2012, mobile health monitoring will be one of the 10 most popular mobile applications(Gartner Research) • Clinicians are early adopters of wireless devices like smartphones and tablets • Physicians, staff, patients and visitors expect and rely on cellular/PCS for communications (mobile workforce) • Mobile access to patients’ electronic medical records (EMR) • Mobile monitoring of patient vitals, lab results, imaging exams

12. DAS Drivers • Higher Education: • Student and faculty multi-carrier cellphone coverage is a matter of convenience and safety • Demand for coverage in stadiums • Parents want instant access to their kids • Students use wireless as primary mode of voice and data communications • Colleges/universities are decommissioning land lines in dorms and buildings • 26% of wireless users are wireless-only • (no landlines)

13. DAS Drivers • Hospitality: • Unlike a university or hospital, hotel or casino customers can stay/go elsewhere if they experience poor cellular coverage. • • Travelers rely on smart phones, tablets and data cards • • Customer satisfaction and retention is driving DAS in the hospitality sector • • A meeting planner that books a • conference at a hotel with poor cellular coverage will only make that mistake once
