It could allow drones to be operated effectively beyond the line of sight.
The programme intends to evaluate the performance of the network at altitude, to experiments to assess video streaming capabilities, transmitting telematics and flight information.
The initiative will be driven from Palo Alto, California, via AT&T’s Internet of Things (IoT) division.
"AT&T and Intel will be testing how the network can enable the most exciting business use cases for drones," said Chris Penrose, AT&T’s IoT Solutions, senior vice president.
"Our LTE network is uniquely positioned to connect industries like delivery, agriculture, construction and insurance. We're using the network to transfer important information, images and video quickly and efficiently — far beyond the boundaries of short range connectivity."
Separately, AT&T also confirmed plans to plunge some $10bn into its enterprise services division in a bid to differentiate in a market fixated on price wars.
