$mart Money in White Spaces
What is TV White Space?• Result of the Digital Transition• Compression of TV channels 2-69 (From
24MHz > 240MHz across the US)• Rules a bit complex, but worth the effort• Now available on an unlicensed basis to
consumers for broadband applications similar to WiFi
• Much lower frequency than current WiFi• Better propagation over geography & line
of sight
What is New About TVWS?• A new concept in spectrum allocation and access• Previously, most spectrum allocated on an exclusive basis• TVWS - a new model for spectrum availability:
– No nationwide contiguous channel footprint– TVWS Devices will regularly check availability with a database– A similar approach has been used for outdoor 5GHz
deployments (www.spectrumbridge.com/udia)– Expect similar spectrum sharing approaches to be used to free
up additional bandwidth for wireless devices in other bands• Today, the FCC leads the world… in this innovative
approach The rest of the world is likely to adopt similar rules making TV White Space devices available worldwide.
Why TV White Space?
WiFi TV White Spaces Source: Dell Inc.
Improvements of 2X to 3X over existing optionsIn indoor applications the improvement in propagation through walls with the additional spectrum that has been made available should produce a 2-3X range improvement over existing 2.4GHz WiFi solutions. For outdoor deployments
VHF and UHF spectrum will provide up to 5 times the coverage of solutions deployed at 2.4GHz.
Rolling up all the “White Space” creates a nationwide footprint
TVWS Availability
Note: Available White Space is not the same as useable White Space.
TVWS Databases• This database maintains current status of all protected
TV band users.
• FCC rules require TVWS devices obtain a list of available channels (based on location) from an Internet-based TVWS database admin.
TVWS Status• The FCC has completed the rule making process and
recently announced the TVWS Database administrators on January 26, 2011.
• Open for Business - Based on FCC Certification• Numerous plans are in place to begin commercial
deployment• Spectrum Bridge will continue to deploy trials in 2011– International arena to make TVWS a global opportunity– Currently, high power networks being deployed– Focus in US moving toward low power solutions

TV White Spaces Moving Forward• At CES, FCC Chairman Genachowski said
“Conservatively, the forecast is for a 35X increase in wireless broadband traffic over the next 5 years.”
• TVWS will be included the next generation of WiFi.• Carriers will use TVWS to offload data traffic from
their networks.• Proliferation of TVWS devices will grow significantly.• Radio suppliers are currently receiving orders in the
thousands for white space radios.
What’s Next?• Database managed networks developing quickly• Spectrum efficiency increased dramatically• Spectrum aggregation across bands inevitable
TV White Spaces are the tip of the iceberg for Universal Spectrum Access!
