Tropical Storm Harvey disrupted at least 17 emergency call centers and 320 cellular sites, and it caused outages for more than 148,000 Internet, TV and phone customers, according to the Federal Communications Commission. It left many people unable to reach out for help or get in touch with family and friends to say they were alive.

It's likely that a similar scenario will occur with Irma, one of the most potentially devastating storms in the state's history, hitting Florida.

To speed up the process of getting everyone back online, telecom companies are starting to use drones. According to experts, these unmanned planes can access where the damage is, finding the best routes to get there and what equipment to bring.

Both AT&T and Verizon have confirmed they are getting drones in place to help with recovery efforts.

According to Kate Harris, a spokesperson for Verizon, the company began using drones last October during Hurricane Matthew to inspect cell towers in North Carolina. She says flooding would have made it hard to send out inspectors to all the sites.

"Reviewing video from the drone, our network engineers realized that one cell site had its equipment on stilts and was not damaged," she says.

The problem was that the generator needed fuel.

"The team was able to send in a team via boat and refueled the generator, getting the site back online to serve customers within just a few hours versus days," Harris says.

AT&T says it has been successfully using drones to help get its systems back up around Houston and other areas affected by Harvey. Art Pregler, National Mobility System's director at AT&T, says they kept drones just outside the area where Harvey was expected to hit so they could deploy them quickly.

The company actually embeds drone crews with repair crews. Pregler says the drone can get pictures of a cell tower, and then the repair team can see what's actually wrong with it. Knowing what's wrong is important.

"The worst thing is to send a crew who doesn't have the right equipment," Pregler says.

Drones can also be used to figure out which areas to avoid — which areas aren't flooded, where there are large piles of debris — and then repair teams can find ways to get out to the cell towers and other facilities without wasting time.

Pregler says they've moved drone teams to Florida, but that it's a more complicated situation than Harvey.

"The entire state is a target of the hurricane," says Pregler. "There is a lot of ongoing coordination."

Pregler says given the shifting information about where Irma is headed, they may have to keep the drone team out of state in Georgia or elsewhere.

The Federal Aviation Administration has now developed special regulations for drones during emergencies. The agency put in temporary flight restrictions. Hobbyists or people who are just curious are told they cannot send out drones during a crisis. But the agency will quickly register government, nonprofit and commercial drones involved in helping recovery efforts. The agency tracks flight plans for the drones — such as where they will fly, how high and when — to prevent collisions.

According to a spokesperson for the FAA, it's not only telecom companies that are using drones. Local fire departments, insurance companies, the Red Cross, railroad companies and even journalism organizations are sending out drones to assess damage.
