Prior to Oklahoma’s decision, 25 other states—Virginia, Wyoming, Arkansas, Kentucky, Iowa, New Jersey, West Virginia, New Mexico, Michigan, Maine, Montana, Arizona, Kansas, Nevada, Hawaii, Alaska, Tennessee, Nebraska, Maryland, Idaho, Texas, Louisiana, Minnesota, Alabama and Indiana—had announced their “opt-in” decisions, as did the U.S. Virgin Islands and Puerto Rico territories.

Meanwhile, the Oklahoma announcement means that the District of Columbia and 13 states have issued an RFP without having their governors announce an “opt-in/opt-out” decision to date: Colorado, Georgia, Massachusetts, Mississippi, Missouri, New Hampshire, North Carolina, Oregon, Pennsylvania, Rhode Island, Vermont, Washington and Wisconsin. Of these states, New Hampshire is only state to announce the winner of its procurement—Rivada Networks.

AT&T officials have stated that deployment of LTE on the 700 MHz Band 14 spectrum licensed to FirstNet could begin as early as this year in certain parts of the country. Public-safety agencies in “opt-in” states are eligible to sign FirstNet contracts that give first responders priority access across AT&T’s commercial networks immediately and preemptive access by the end of the year.

AT&T will build the FirstNet RAN in “opt-in” states or territories at no cost to each jurisdiction, although local public-safety entities will be responsible for paying subscription costs and end-user device expenses. However, the law that established FirstNet stipulates that individual public-safety agencies and potential first-responder users are not required to subscribe to the FirstNet service.

“We’re honored to deliver this game-changing communications tool to first responders in Oklahoma,” AT&T Oklahoma President Steve Hahn said in a prepared statement. “I applaud Gov. Fallin’s diligence and thank her and her staff for the care they’ve taken to ensure the FirstNet network that’s built in Oklahoma meets the needs of the public-safety community and Oklahoma residents for years to come.”
