The Federal Communications Commission has unanimously approved an order that would establish interoperability standards for a nationwide public safety communications network. The order, which the commission will publish in the Federal Register as a proposed rule, requires all public safety mobile broadband networks to use a common air interface, specifically Long-Term Evolution, to support roaming and interoperable communications. LTE is compatible with older and new devices, making network interconnection and interoperability more likely as technology continues to evolve, according to an FCC fact sheet.
