The FCC is reminding wireless microphone users operating in the 700 MHz band that they must retune or replace their equipment this week to ensure they don't interfere with commercial and public-safety LTE networks that are being constructed in the band. The FCC's ban on 700 MHz microphones becomes effective on June 12. The FCC said violators "may be subject to monetary forfeitures, seizure of the radio equipment, or criminal sanctions." Article
