requiring the licensee for the 2155-2180 MHz spectrum
to provide – using up to 25 percent of its wireless network capacity – free, two-way broadband
Internet service at engineered data rates of at least 768 kbps downstream. Additional obligations
associated with the licensee's free broadband service would include a requirement to provide a
network-based filtering mechanism for the free Internet service in order to protect children and
families, and a requirement that the network allow for the use of open devices.

The build-out requirements for the licensee, as proposed today, would be to provide
signal coverage and offer service to at least 50 percent of the total U.S. within four years and to
at least 95 percent of the U.S. population by the end of the 10-year license term.
