GAO said Wednesday it reviewed data and interviewed leaders from 11 federal agencies that assist in research or community IoT projects or have direct authority over IoT matters.
The watchdog agency determined that eight of the 11 agencies reviewed perform broad research efforts on IoT-related technologies and concepts that include communications systems, wired and wireless network systems.
GAO also found out that the Transportation Department provided $40 million to help a community implement smart technologies designed to boost surface transportation service.
The Environmental Protection Agency allocated $40,000 for two communities to establish methods of deployment for air quality sensors, GAO added.
Officials told GAO that an interagency task force has drafted a Smart Cities and Communities Federal Strategic Plan and aims to finalize the plan this summer.
