Wireless Demand at Universities Growing Demand and Expectations
Students and faculty depend on mobile devices
Parents need to stay in touch with students
Attendees at sporting and other events demand wireless connections Universities rely heavily on web-based content and delivery of on-line courses Universal campus demand in classrooms, residence halls, libraries, and stadiums
Growing Concerns
Students, parents, and university staff view poor wireless availability as a major security concern
University Wireless Network Challenges Coverage and Capacity
Traditional methods to provide coverage and capacity often ineffective ― Dense building materials and older construction ― Campus topography ― Mobile user crowds at sporting and other events ― Large complex facility footprints
Aesthetics and Budget Constraints
Preserving valuable campus real estate with an optimal solution
Limited network budget resources
DAS Solution/StrategyOptions • Build Your Own – Capital intensive – Still need carrier involvement and commitment to activate networks • Carrier Direct Relationships/Solutions – Manage multiple relationships and projects or – One carrier is the lead and manages all others • 3rd Party Neutral Host – Works with all carriers on university’s behalf – Some have the ability to manage macro and DAS environments on campus for the university
DAS Benefits for Universities Coverage, Capacity, Aesthetics
Campus-wide wireless coverage and capacity
Ubiquitous wireless availability via multi carrier host
Networks scale-up building-by-building as demand increases
Satisfy students, faculty, alumni and staff expectations
A competitive edge for attracting top students and faculty
Equipment blends into existing campus landscape
Streamlined Operations
Insure campus-wide efficiency of staff operations
Attractive Financial Terms
New Revenue Streams
No build-out costs
No day to day management expense
Requirements for the University • Availability of Fiber and Conduit, new or existing, to key locations • Dedicated Hub Location – Central to system and target coverage areas – ~2,000 sq. ft of space – Easy access to utilities demark
• 24/7/365 access to hub and service locations • Support and assistance with local regulatory agencies.

Goals
• Solve for carrier coverage and capacity offload needs • Balance aesthetics and economics in developing the most effective solution that will drive carrier participation
Design Methodology Approach:
Next Steps:
• Consider carrier direction on coverage and capacity needs
• Obtain RF requirements from carriers • Conduct benchmark signal testing
• Consider direction from the University on coverage expectations and priorities • Targeted coverage of defined coverage areas • Accommodate all FCC licensed frequencies and technologies: CDMA, GSM, iDEN, LTE, PCS and WiMax
• Create preliminary design and obtain carrier approval • Perform CW tests to validate design • Update design as needed (based on test results) and secure final carriers approval
Project Implementation Locations of HUB, Antennas and Nodes:
Fiber Design:
•
Will work with the University to develop a DAS that utilizes both new and/or existing structures
•
Based on meeting all of the WSPs RF link Budget requirements
•
Sensitive to the aesthetic concerns throughout the campus
•
Fiber distance limitation is 10 miles
•
Amount of fiber required will be based on the final design
•
Work with the University to utilize existing fiber or install new fiber to meet the DAS requirements.
•
•
Visual simulations of antenna and equipment locations will be presented to the University for approval Engineered construction drawings will be developed, local jurisdictional approvals and building permits will be obtained.
Project Management: • • •
Provide Construction Management and Project Management Services including project updates, schedules and progress meetings Equipment Procurement, Installation and Commissioning Carrier Integrations
