Last week, UTC and NEI filed an ex parte letter with the FCC listing 43 nuclear power plants that use Telex equipment operating on the 700 MHz and/or 800 MHz bands (i.e. above 698 MHz). The letter supplements the ex parte filings that UTC/NEI previously made with the FCC in regards to establishing a transition period to migrate off the 700 MHz band.

This move comes as an FCC deadline of June 12, 2010 looms for broadcast auxiliary operations, such as wireless microphones - including Telex headsets - to stop using the 700 MHz band which has been reallocated for 4G commercial and public safety communications. Not coincidentally, the FCC released a public notice reminding operators of wireless microphones in the 700 MHz band to either retune or replace their gear by June 12, 2010. Such an action would "avoid interference to public safety communications and next generation commercial services," according to the FCC. The list of equipment affected by this notice is listed here.
