Abstract
With the rapid development of low-altitude applications, there is an
increasing demand for low-altitude wireless networks (LAWNs) to simultaneously
achieve high-rate communication, precise sensing, and reliable control in the
low-altitude airspace. In this paper, we first present a typical system
architecture of LAWNs, which integrates three core functionalities:
communication, sensing, and control. Subsequently, we explore the promising
prospects of movable antenna (MA)-assisted wireless communications, with
emphasis on its potential in flexible beamforming, interference management, and
spatial multiplexing gain. Furthermore, we elaborate on the integrated
communication, sensing, and control capabilities enabled by MAs in LAWNs, and
illustrate their effectiveness through representative examples. A case study
demonstrates that MA-enabled LAWNs achieve significant performance improvements
over traditional fixed-position antenna-based LAWNs in terms of communication
throughput, sensing accuracy, and control stability. Finally, we outline
several promising directions for future research, including the MA-assisted
unmanned aerial vehicle (UAV) communication/sensing, the MA-assisted reliable
control, and the MA-enhanced physical layer security.
