The Federal Register (PDF) today revealed that the FCC's white space wireless rules would take effect on January 5. The milestone will clear companies to start using the frequencies between channels and will also require the promised white space database to tell companies and users which airwaves are free. One company is expected to manage the database, but the FCC's Hugh Van Tuyl said that the agency was still determining who would be responsible and wasn't tied to the January 5 date.
