First Claim
1. A wireless device network comprising:
- a plurality of device nodes that share a radio frequency spectrum using time-division multiple access (TDMA), wherein the plurality of device nodes are configured to transmit wireless communications on a plurality of channels during a future TDMA frame of communication, wherein each respective channel of the plurality of channels has a plurality of timeslots associated with the respective channel; and
a timeslot allocation function comprising a processor and a memory, the processor configured to;
receive signal characterization data characterizing at least a first radio altimeter signal transmitted by at least a first radio altimeter;
using the signal characterization data, predict a frequency of at least the first radio altimeter signal during the future TDMA frame of communication;
identify conflicting timeslots associated with each respective channel of the plurality of channels, wherein the predicted frequency of the at least a first radio altimeter signal overlaps with the respective channel during the conflicting timeslots; and
transmit a TDMA timeslot allocation, for wireless communications during the future TDMA frame of communication, to the plurality of device nodes, wherein the TDMA timeslot allocation includes non-conflicting timeslots associated with each respective channel of the plurality of channels, wherein the predicted frequency of the at least a first radio altimeter signal does not overlap with the respective channel during the non-conflicting timeslots.
