This webinar provided an overview of TV white spaces and the economic value of this spectrum. TV white spaces refer to unused spectrum in between broadcast television channels that has been made available for unlicensed use. This spectrum has advantages over existing unlicensed bands in that its lower frequencies propagate better over long distances. The webinar discussed the large amount of spectrum availability, potential uses cases, an expected timeline for certification and standards development, and the global interest in TV white spaces.

1. Welcome to: Introducing TV White Spaces VoIP Users: If you are using VoIP for the audio portion of the presentation, you should already be connected to audio using your computer’s microphone and speakers (VoIP). A headset is recommended. Telephone Users: If you are joining the audio portion of this presentation VIA TELEPHONE, and haven’t already dialed in, simply dial the number you see in the section of the control panel marked “AUDIO” and use the access and pin codes provided there. Questions: We will address questions at the conclusion of this webinar. You may send your questions to us ANYTIME throughout the presentation-- via the text chat tool in the control panel, titled “QUESTIONS”. Viewing Tip: At any time throughout the presentation you may MINIMIZE the CONTROL PANEL and view just the presentation screen by clicking on the small double black arrows at the TOP of the control panel . This session is being recorded. We will send all attendees a link where you can access it as soon as it is posted.

5. What is TV White Space? As a result of the Digital Transition (from Analog TV) additional spectrum became available for broadband applications. Traditional TV channels were from 2-69. Over time these channels have been compressed and some have been sold to cellular carriers for 4G solutions. The rules are quite complex and will be discussed in a subsequent webinar, but at 50,000 feet this spectrum will be available on an unlicensed basis to consumers for broadband applications similar to WiFi. The attraction of TV White Space is that it is a much lower frequency than existing unlicensed spectrum. The lower frequencies propagate better over distance and through walls.

7. The Macro Level View Rolling up all the “White Space” creates a nationwide footprint. . Note: the actual amount of White Space is dependent on device type. . The above sponsor logos are trademarks of The Brattle Group and Spectrum Bridge, Inc., respectively. © 2010. All rights reserved.

8. What is New About TV White Space? A new concept in spectrum allocation and access Before today most spectrum was allocated on an exclusive basis but with TV White Spaces the FCC is creating a new model for spectrum availability: -No nationwide contiguous footprint -Radios that use TV White Space will check availability with a database -A similar approach has been used for outdoor 5GHz deployments (www.spectrumbridge.com/udia) -We expect similar spectrum sharing approaches to be used to free up additional bandwidth for wireless devices in other frequency bands Today, the FCC leads the world in this innovative approach but the rest of the world is likely to adopt similar rules making TV White Space devices available worldwide.

9. Who Can Use TV White Space, and for What? The short answer: Anyone TV White Space has been designated as “unlicensed” spectrum so certified devices can be purchased and used by anyone without a need for special permits or licenses The FCC did not specify what TV White Space should be used for but the rules are most favorable to broadband data applications both indoor (around the home and office) as well as outdoor (community) solutions The FCC allows for extension of existing technologies like 802.11 (WiFi) and 802.16 (WiMax™) as well as new and innovative technologies and solutions, as long as they follow the rule and validate the spectrum they can use with a database. Note that the FCC has also allowed for people to propose solutions based on sensing technologies but these require more rigorous testing for certification.

12. Why TV White Spaces? Improvements of 3X to 5X over existing options For outdoor deployments VHF and UHF spectrum will provide up to 5 times the coverage of solutions deployed at 2.4GHz. In indoor applications the improvement in propagation through walls with the additional spectrum that has been made available should produce a 3X improvement over existing 2.4GHz WiFisolutions.

20. Using Radio Spectrum In producing spectrum based services, providers mix spectrum with capital and labor. It is optimal to add spectrum to the mix up to the point where the extra revenue (or cost savings) just equals the price of the spectrum. For example, a cellular network can increase capacity by a given amount by either adding radio spectrum or by dividing cells (i.e., by adding capital.)

21. The Good News for White Spaces Unlicensed white space spectrum is free! This means you can use more of it: -up to the point where using more no longer adds to your revenue or reduces your costs. Just make sure your business model is appropriate for the unlicensed environment: -no protection from interference The above sponsor logos are trademarks of The Brattle Group and Spectrum Bridge, Inc., respectively. © 2010.

22. The Bad News for White Spaces Unlicensed white space spectrum is free! This means others can use more of it: -up to the point where using more no longer adds to theirrevenue or reduces their costs. Just make sure your business model is appropriate for the unlicensed environment: -no protection from interference, -they do not consider the costs they impose on you!
