  Unmanned aerial vehicle (UAV) communications have attracted significant
attention from both academia and industry. To facilitate the large-scale usage
of UAVs for various applications in practice, we provide a comprehensive survey
on the prototype and experiment for UAV communications. To this end, we first
provide an overview on the general architecture of the prototype and experiment
for UAV communications, and then present experimental verification for
air-to-ground channel models and UAV energy consumption models. Next, we
discuss measurement experiments on two promising paradigms of UAV
communications, namely cellular-connected UAVs and UAV-enabled aerial
communication platforms. For the former, we focus on the feasibility study and
address the interference mitigation issue. For UAV-enabled aerial communication
platforms, we present three scenarios, namely UAV-enabled aerial base stations,
UAV-enabled aerial relays and UAV-enabled aerial data collection/dissemination.
Finally, we point out some promising future directions for prototype and
experimental measurements for UAV communications.
