Abstract
In one embodiment, a wireless device network comprises: a plurality of device nodes using TDMA, the plurality of device nodes configured to transmit during a future TDMA frame of communication on channels having timeslots; and a timeslot allocation function comprising a processor and a memory, the processor configured to: receive signal characterization data characterizing a radio altimeter signal; using the signal characterization data, predict a frequency of the radio altimeter signal during the future TDMA frame of communication; identify conflicting timeslots for respective channels, wherein the predicted frequency of the radio altimeter signal overlaps with the respective channels during conflicting timeslots; and transmit a TDMA timeslot allocation, for wireless communications during the future TDMA frame of communication, to the plurality of device nodes, the TDMA timeslot allocation including non-conflicting timeslots where the predicted frequency of the radio altimeter signal does not overlap with the respective channels during non-conflicting timeslots.
