1 TV White Space Technical Overview & Rural Education & Research Applications Informational Meeting Oct. 16, 2012 Hilton Oakland Airport Boardroom 2 -- Building 5

2 Presentation Outline Introductions Technological overview Trial projects Product feature set Applications and features for the research and education community Summary

3 About Carlson RF design & manufacturing firm Northern California, since 1999 Specializing in rural regions & rugged terrain Full line of fixed--wireless equipment Leader in TV white--space device development with RuralConnect product line

4 Overview of the Technology Definition and background Benefits Non--line line--of of--sight broadband Long range & wide--area coverage Spectrum managed by database Cognitive, software--defined radio Technology roadmap

5 What are White Spaces? Available spaces located between occupied channels in the RF spectrum 200 MHz of available spectrum 2009 DTV transition made more space available in the UHF range 2010 FCC declared white--space spectrum can be used for broadband

6 Non--Line Line--of--Sight (NLOS) Operation Unlike microwave, UHF spectrum operates without line of sight Requires little infrastructure Quick and effective deployment Rugged or hilly terrain Forested areas City parks Blind alleys Secluded urban areas

7 Long Range & Wide--Area Coverage Wi--Fi vs. TVWS 25--mile propagation radius Red areas show the range of best coverage UHF spectrum consists of low--frequency ground waves Propagates farther than Wi--Fi Minimal infrastructure required Quick, effective deployment

channels Many channels available in urban and rural areas Carlson

8 Spectrum Database Management Available channels vary from one location to another FCC--designated database companies map available channels Many channels available in urban and rural areas Carlson works with the top database providers to ensure interference--free free operation

9 Cognitive, Software--Defined Radio Dynamically interacts with database Operates over entire frequency band Can scan horizon of spectrum and pick best channels Adaptable bandwidth Can use a fraction of a channel Or bond multiple channels for needed bandwidth Modulation rates auto--adapt adapt to environmental conditions

10 Technology Roadmap Rural Broadband Video Surveillance Smart Grid Smart Cities Agriculture M2M Vending machines Sensors Alarms Smart homes Transportation SOHO Oil & Gas High power, fixed Low power, fixed Low power, mobile

11 Questions about the technology?

12 Carlson TVWS Trial Projects 12 experimental FCC licenses 6 trials begun All at different stages of development Rural, underserved communities Rugged terrain Heavy foliage Low teledensity Seeking NLOS solution

13 Purpose of Experimental Projects Develop the most effective product Make improvements based on real--world scenarios Test product under challenging conditions Demonstrate the potential of the technology

Hilly, forested landscape Local WISP with hundreds of failed installs Rural

14 Carlson Trials: Eastern U.S. Vermont, Connecticut & Massachusetts Low teledensity & low fiber miles Hilly, forested landscape Local WISP with hundreds of failed installs Rural Central Florida Low teledensity Dense foliage, marshland communities 12,000 previously unservable users Public--private partnership

Known as radio black hole by area public safety officials Rural Oklahoma WISP

15 Suburban Michigan Carlson Trials: Central U.S. WISP formed to serve 3 bedroom communities near Grand Rapids Scattered homes on thickly forested acreage Known as radio black hole by area public safety officials Rural Oklahoma WISP with hundreds of failed installs in 3 counties Water tower & TV tower infrastructure

since1996 with Carlson narrowband VHF radio Klamath, California 40+ square miles along the mouth

16 Remote Alaska Island Carlson Trials: Western U.S. Rural telephone co--op op Remote island community surrounded by mountain ranges Phone service since1996 with Carlson narrowband VHF radio Klamath, California 40+ square miles along the mouth of the Klamath River Very rugged terrain, heavily forested Scattered population Yurok Tribal Territory Cultural prohibition on visible infrastructure

community Serving a scattered, remote population Near line--of of--sight 900 MHz would

17 The Yurok Connect Project: Challenge for the technology The Challenge Carlson chose the toughest proving ground we could find for our developing product Challenge for the community Serving a scattered, remote population Near line--of of--sight 900 MHz would require many towers and repeaters Culturally unacceptable Cost--prohibitive Needed a better solution

The solution The Yurok Connect Project: The Solution Carlson team picked

that UHF signal reached well into obscured areas Results: immediate community

station,, elementary school and office building Results: Product improvement

equalization algorithm necessary Innovative antenna design Effectively

18 The solution The Yurok Connect Project: The Solution Carlson team picked locations for 3 major access points that could be hidden in trees Discovered that UHF signal reached well into obscured areas Results: immediate community improvement Installed dedicated public safety line Currently installing fire station,, elementary school and office building Results: Product improvement Better equalization Sharp canyons created significant multipath A more robust equalization algorithm necessary Innovative antenna design Effectively capture NLOS capabilities of signal Omnidirectional and sector UHF base station antennas

19 Questions about the trial projects?

20 Carlson s s RuralConnect Software--defined UHF broadband radio True NLOS performance First model designed to WISP market specs Affordability Long range & coverage Reliability & ruggedness Compliance with FCC regulations Ease of installation & service

21 RuralConnect Feature Set Full UHF range MHz Up to 16 Mbps Low latency, resists fading Flexible configuration & applications Multipoint or point-to-point Reliability Remote management and diagnostics Web-based graphic user interface (GUI)

22 Carlson UHF Antennas Base station antennas High--gain gain omni Sector CPE antennas Yagi Log periodic

23 Rural Education Applications Wi--Fi hotspots backhaul Emergency call boxes Surveillance Remote/satellite classrooms Quick deployments of emergency communications

24 State--of of--the the--art Rural Campuses Put existing spectrum to work Complement existing broadband capabilities Enhance: Administration Academics Research Campus safety Student retention

Competitive Leadership in a Knowledge--Based

for researchers Advance online education

25 Competitive Leadership in a Knowledge--Based Economy Build meaningful collaboration Bring together scientists and researchers from around the globe Leverage distant resources for researchers Advance online education systems Assessment Curriculum development Student engagement

26 Improve Quality of Campus Life Better student participation in campus culture Increased student retention rates Better access to campus resources Timely communication with students Critical emergency communications Better safety at campus events

27 Sample Applications: Ubiquitous Wi--Fi Stay connected anytime, anywhere Blanket acres of campus with Wi--Fi coverage Classrooms Common areas Residence halls Benches Parking lots Walking between classes Learning in the outdoor classroom Lounging under a towering oak tree

28 Conclusion Carlson has more than a decade of experience in developing effective rural solutions Customer--driven product development TV white space offers 200 megahertz of top--quality spectrum Carlson s s trials demonstrate the effectiveness of the technology RuralConnect offers a robust feature set that matches the needs of the rural education community
