Publication number: 20240080876Abstract: In one possible embodiment, a wireless network with dynamic transmission control is provided that includes a multiple of nodes. The nodes include an arbiter and multiple client nodes. The arbiter is configured to control an operation of the client nodes by defining communications operation cycles and allocating a bandwidth to each of the client nodes on a cycle by cycle basis in response to requests for bandwidth from the client nodes.Type: ApplicationFiled: May 31, 2023Publication date: March 7, 2024Applicant: AeroVironment, Inc.Inventors: John F.
