Abstract

The present invention extends to methods, systems, devices, apparatus, and computer program products for wireless communication between an operator of a remotely operated aircraft and a controlling entity. A communication converter at a remotely operated aircraft converts between radio communication (e.g., VHF airband) and communication over another wireless network (e.g., over a cellular network). Thus, aspects of the invention can be used to facilitate (e.g., more localized) radio communication between an operator (e.g., pilot) of a remotely operated aircraft and a controlling entity (e.g., a control center) when the operator (e.g., pilot) is physically located outside of (e.g., VHF) radio range from the controlling entity. Accordingly, a two-way voice communication link can be established between the operator and personnel at a control center.
