330LT2 - Frequency Changes to Wireless Sound Systems 


The Federal Communications Commission (FCC) has announced its planned completion of the transition of the 617-652 MHz and 663-698 MHz spectrum bands from wireless microphones and television broadcasts to wireless communicators (such as cellphone companies) by July 13, 2020. This transition began in 2017. Parishes should be aware that 600 Mhz wireless sound systems (an industry standard for churches, until recently) will be vulnerable to sound system failure as of the 2020 completion date, if not earlier. Churches are strongly advised to contact the company which installs or maintains their wireless system as soon as possible to determine whether an upgrade is needed.
