WhiteSpace Alliance and Inatel Demonstrate Coexistence of Whitespace Broadband and Digital Television in Brazil

The WhiteSpace Alliance (WSA®), a global industry organization enabling sharing of underutilized spectrum, today announced results of a trial in Brazil demonstrating coexistence of whitespace broadband and digital television signals. The test was conducted in collaboration with Inatel, the National Institute of Communications in Brazil, and is the first formal assessment of TV whitespace application in that country.

Whitespace technology uses idle TV band spectrum (whitespace) to deliver fixed wireless broadband services at distances up to 30 km. Ensuring that these signals do not interfere with normal TV broadcasts is a critical step in using TV whitespaces to provide widespread Internet access. White space solutions can support a broad range of commercial, education and government applications, and are ideally suited to delivering services to underserved populations in rural and remote areas. The technology can be used in environments where wired infrastructure is too costly to deploy, or vegetation makes traditional line-of-sight wireless solutions unreliable.

“The global transition from analog to digital television is freeing up large amounts of broadcast spectrum which can be used to efficiently provide Internet access,” said Dr. Apurva N. Mody, Chairman of WhiteSpace Alliance. “These test results will help speed development of a national regulatory framework for TV whitespace deployment in Brazil, bridging the Digital Divide for broadband services.”

The Inatel report, published in Portuguese, is available on the WhiteSpace Alliance website.

WhiteSpace Alliance, developer of Wi-FAR® and WSAConnect® interoperability specifications, has a following of more than 200 major commercial, academic, government and regulatory organizations around the world.
