Explanation
'Project Loon' was an ambitious research and development project by Google (later Alphabet Inc.'s X) aimed at providing internet access to rural and remote areas. It involved high-altitude balloons floating in the stratosphere at an altitude of about 18 km to 25 km, creating an aerial wireless network. These balloons acted as floating cell towers, transmitting internet connectivity to ground stations and then to users' LTE-enabled phones. Thus, it was directly related to wireless communication technology.
