Spectrum 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


Why are we not sharing Radio Waves?

We rely on a 100 year old allocation system, from a time when coexistence was impossible, when we have all the technology, and most of the regulation, to permit significant sharing

We share the airways for commercial and government flights We share the roads for personal and public safety traffic We share other critical infrastructure

– Water and Electric Grids– The Internet– The phone networks

Different sharing methodologies but all effective


The Fear

Without some form of “supervision” the result will be a train wreck - or worse


The way we have to think of things

Access for Multiple, competing, services can be effectively managed in real timeAny unused spectrum is “white space” and has the potential to be sharedSharing does not have to mean uncontrolled, or free


• 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

• Authorized Shared Access• Proof of concept applications on android handsets• TVWS + Licensed spectrum trials in the works• Cloud based spectrum allocation system and co-existence manager• Radio/chip level integration

Current Implementations


Unlike our normal model, the FCC dictated the way we manage TV White Space, and requires us to look after your protected interest at no cost to you, 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

Unlicensed Spectrum: TV White Space


Rolling up all the “White Space” creates a nationwide footprint

Note Available White Space is not the same as useable White Space

What is TV White Space?

Each available Channel = 6MHz of spectrum


Going Forward: TV White Space being adopted 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 fixedIETF (PAWS -Protocol for Accessing White Space) database to radio interface

Worlds First commercial TVWS Deployment– Wilmington, NCPartnership with Local Authorities and Public Safety Entities


1st Generation TVWS Radios

All TVWS radios exploit the fact that they can get 3-5 times the coverage of comparable WiFi radios running at 2.4Ghz

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 18 Months from now low power devices will start to become

commercially available, devices that are “personal & Portable”– The next generation WiFi router– Enhanced sensor networks


What are they used for?

Industrial, Commercial, Public Safety and Local Governments:– Video Cameras

• Monitoring evacuation routes• Security• Counting traffic• Public access

– Sensors• EPA, water/air quality

– Energy Management• Lighting control• Industrial control

– Public Access• WiFi Hotspots in parks and open spaces


Wilmington NC, The worlds first Commercial Deployment

The applications in Wilmington and New Hanover County solved issues that they had previously been unable to address

Interference (congestion) and/or range with existing solutions could be overcome with the use of TV White Space

Applications include:– Video surveillance– Facilities control (Lighting)– Public Wifi Access– Improved city services

Applications that have an ROI in weeks or months and are repeatable in towns and cities across the country


Unique ability to control and manage radios

Frequency agile radios are a reality today– iPhone 4S (800,900,1800,1900,2100,2400MHz)– TVWS radios 450-900MHz

The database can manage allocation within a small geography, short duration and specific frequency– There is no reason that the rules have to be the same everywhere.– Behavior can be modified at any time– Spectrum can be added/removed from the pool in real time

Coexistence can now be managed (traffic control)


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

Spectrum Sharing can be monetized to allow for new funding options.


Fees based Spectrum Management

SBI platform translates Spectrum into an asset, managing it (licensed or unlicensed) in 3 dimensions to allow the asset to be shared, maximizing

the efficiency of use and realizing the maximum value
