A new Federal Communications Commission (FCC) ban of wireless microphones that operate in the 700 megahertz frequency went into effect yesterday (June 12, 2010), which requires churches that use them to replace them.
Only emergency responders -- such as police and firefighters -- are now allowed to use the frequency, according to the Christian Broadcast Network website.
Currently, about 10-12 percent of the wireless mics used in churches violate the ban, according to Matt Nodine, chief of staff of the Wireless Telecommunications Bureau of the FCC.
Churches or other facilities that now use the 700 megahertz frequency could face fines and criminal penalties.
Congregations across the United States have already spent millions of dollars to replace the devices.
