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.

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.

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. What is 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. Benefits of DAS

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

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)

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
