Verizon's Andres Irlando is officially putting AT&T and FirstNet on notice: The interoperability fight is not over. Not by a long shot.
"We don't have true interoperability," said Irlando, who is in charge of Verizon's "public sector" business, which includes sales of services to federal, state, public safety and education customers. "It's time for the industry to come together and solve for true interoperability."
Specifically, Irlando is calling for interoperability among Verizon, AT&T, FirstNet and others across a number of services that are specific to public-safety customers. Those services include priority and preemption (which ensures public safety users can access a connection amid network congestion); mutual-aid roaming (where public-safety customers would automatically switch to another nearby network if their primary connection is disabled); application interoperability (wherein features and functions specific to public-safety users work across all networks); and push-to-X interoperability (which includes everything from push to talk services to mission-critical video)
However, AT&T's FirstNet successes appear to have generated some concerns among its competitors.
"AT&T is merely attempting to leverage its FirstNet relationship to alarm potential customers into becoming AT&T subscribers," T-Mobile wrote to the FCC last year. "In fact, AT&T and FirstNet have exaggerated the purported interoperability limitations of other carriers in order to drive subscribers to AT&T's network. AT&T and FirstNet's scare tactics particularly disadvantage potential customers of providers like T-Mobile, which plans to provide innovative public safety offerings."
Others agree.
"The level of priority and preemption between users on FirstNet/AT&T and other networks must be standardized to avoid a situation in which a high priority public safety user on one network is treated as a commercial user on another network," wrote officials from New Mexico's Department of Information Technology in comments to the FCC. "This is particularly important in situations where users from different jurisdictions are responding to a common emergency, such as a wildfire within a remote region of the state."
