•Introduction to Spectrum Bridge

•Summary of the efforts of the Database Administrators

•TVWS status today

•Where we see things going•White space beyond TV band

•Co Existence

•Q & A

Spectrum BridgeSpectrum Bridge

•Privately held company based in Florida•Our background is in radios and wireless networks

•We know when to manage interference and when to avoid it

•SBI is a Spectrum Management Company•On behalf of Spectrum Holders

•Work with Holders to identify and monetize underused spectrum

•The Spectrum Holder dictates the terms

•Only authorized shared Access allowed

[ 4 ]

• SpecEx • an operational secondary marketplace for spectrum

• UDIA • a co-existence and interference manager for 5GHz TDWR

• TVWS• First commercial TVWS solutions

• Multiple international trials

Unlike our normal model, the FCC dictated the way we manage TV White Space, and requires us to look after Broadcasters protected interest at no cost to them, and secondary access is free – this alone is not a business model for us.

It does allow for us to continue to improve, and prove out, the basic technologies, provide value added services and use TVWS as a model for other spectrum bands

Database GroupDatabase Group

When the FCC announced 9, and then 10 entities to manage TV White Space, we took the initiative organize the group, to ensure that the results were consistent. 8 of the original 9, and then Microsoft, signed up to create 2 specifications.

 The first defines a mechanism for how we synchronize registration data amongst database operators. – That was critical because you would otherwise have to interact with all

the providers,

The second is a calculation document. This is designed to ensure that all the Databases yield the same results.

The first formal version of these documents was provided to the FCC for publication, they are available on ECFS, or you can access to the documents here:

Meeting the requirements is not good enoughMeeting the requirements is not good enough

The group has not been satisfied with the minimum requirements– We recognize it is in all our best interests

– The group is understandably proud of its efforts

Synchronization will be done in near real time – not the 24 hour minimum

Contour calculation is being driven to cm accuracy – not the 10m requirement

We are proposing variable, and shorter channel assignments

Certification and initial deploymentCertification and initial deployment

Spectrum Bridge has navigated the FCC certification process– Long and evolved process starting with trial system in late 2009

– Not without issues

– Process is still far from perfect

– It will take all of us to help improve it

Spectrum Bridge went through certification in parallel with a radio

The first commercial deployment is scheduled to go live in late January in Wilmington NC.

Still pieces of the puzzle to put together– Introduction of additional databases and radios

– FCC capability to support unlicensed microphones

[ 9 ]

1st Generation TVWS Radios1st Generation TVWS Radios

The 1st certified radio is a Fixed High Power radio designed for outdoor P2P and P2MP configurations for rural broadband and telemetry/SCADA applications

Several other Fixed High Power radios are in the pipeline

All these radios have to be professionally installed, stay in one place and have to register with the database– The number in operation in 2012 will be very limited

– We will have the ability to know where every single one is, and who is using it This provides us with an opportunity to study and understand the behavior, and make adjustments prior to the mass produced, consumer, personal/portable solutions anticipated in late 2013.

[ 10 ]

Unique ability to control and manage radiosUnique ability to control and manage radios

TVWS database management system brings a new level of flexibility and control that has never been possible before.

We are going to know where all these radios are because they are required to request channel lists at least daily. – The SBI solution has a high degree of capability and flexibility allowing us

to manage access with great precision in the time, frequency and area domain, by manufacturer and serial number.

SBI can restrict types of devices or specific devices from operating should it become necessary. And of course the FCC can also adjust the rules on a macro level and we can make adjustments to the ecosystem in real-time. – We can also get surgical to address specific problems quickly where and

when they arise, without the need for wide sweeping, and possibly time consuming changes

Going Forward: TV White Space being Going Forward: TV White Space being adopted worldwideadopted worldwide

Trials operating under experimental licenses

Spectrum Bridge has versions of it’s platforms working in several countries with plans to expand in 2012to several new international markets

A number of standards bodies are working on TVWS technologies:IEEE 802.11 (Super WiFi): low power personal/portableIEEE 802.22 (White Space Alliance) high power fixedIEEE 802.19 (co existence) IETF (PAWS -Protocol for Accessing White Space) database to radio interface

Going Forward: Other “ White Space”Going Forward: Other “ White Space”

• TVWS concepts can be easily adapted to provide shared access to other bands the government is considering opening up

• Shared Access with existing incumbents is a prerequisite

• Access could be on a priority basis

• Pre-emptive or planned (for Public Safety and DOD spectrum)

• QOS and co-existence can be managed

• Use can be monitored and, potentially, charged for

• One day we hope this will also allow you to monetize the sharing of some of your protected spectrum, without compromising your primary use.

• The Database manages co-existence through policy and regulation• How does this integrate with 802.19?

• How does this migrate to a combination of top down (database) and bottom up (sensing)?
