Abstract
Systems and methods to synchronize wireless device nodes in the presence of a FMCW radio altimeter are provided. In one embodiment, a wireless device network comprises: a plurality of device nodes that share a radio frequency spectrum using time-division multiple accesses; a network synchronizing device in wireless communication with the plurality of device nodes, the network synchronizing device coupled to a timeslot allocation function, wherein the timeslot allocation function allocates to the network synchronizing device a timeslot on a first designated synchronization channel within the radio frequency spectrum; wherein the network synchronizing device broadcasts an arbitrary timeslot synchronization beacon to the plurality of device nodes on the first designated synchronization channel in the timeslot; wherein the arbitrary timeslot synchronization beacon comprises a Sync Timeslot identifier that identifies the timeslot, and a Sync Time indicator that includes a time that the arbitrary timeslot synchronization beacon was transmitted.
