Chief executives from the Big Four broadcast networks wrote Federal Communications Commission Chairman Kevin Martin today over concerns they have about the reliability of “white space” devices relying solely on spectrum-sensing technology as well as the commission’s plan to set power limitations at 40 milliwatts, TVNewsday says. The letter asked, “If millions of unlicensed devices flood the market in the next few years, and it turns out that sensing still does not work, or that 40 milliwatts is far too high … how will that damage be undone?” The letter, signed by News Corp.’s Peter Chernin, Walt Disney’s Robert Iger, CBS’ Leslie Moonves and NBC Universal’s Jeff Zucker, also reiterated the broadcasters’ wish for public comment and peer review of the FCC’s report on white space.
