The Federal Communications Commission announced that states that want to opt out of the FirstNet radio access network for first responders must do so by Dec. 28. Opt-out notices must be sent by the governors of the states or territories to FirstNet and the National Telecommunications and Information Administration.

The Federal Communications Commission last week approved guidelines it will use to evaluate network proposals for states that want to opt out of FirstNet, the wireless broadband public safety network that AT&T is developing. AT&T was awarded the $6.5 billion contract earlier this year.
