WSA promotes architectures and technologies to enable more efficient use of spectrum to realize a wide variety of applications ranging from wireless broadband and smart grid to homeland security.

WSA promotes the development, deployment and use of standards based products and services for use in the WhiteSpace spectrum, thus enabling companies to provide broadband connectivity at reasonable cost. WSA conducts workshops, outreach activities and provides its members with much needed information & collaboration to succeed both in the market place and with regulatory requirements.
