A North Carolina research firm is flying drones over a volcano that are using Wi-Fi for telemetry: RTI International, based in the famous Research Triangle Park in Chapel Hill, N.C., will fly drones with cameras and Wi-Fi equipment over Mt. St. Helens. The drones will form an in-air network and will be able to relay to ground stations. This means that a few planes in air could span hundreds of miles back to a ground station. The challenges in maintaining long-distance, low-power mobile in-flight networks seems daunting, but the firm will test out the system in August--on lab carts.
