Abstract
A system and method for time division multiplexing voice and situational awareness data with defined transmission and retransmission windows comprises coordinating the voice and situational awareness windows at defined times across all nodes. Control signal windows and control signal retransmission windows are also defined to propagate control signals to coordinate the various voice and situational awareness windows. Voice data is prioritized for bandwidth.
Claims20
A method comprising:
- defining a primary voice window in a time division multiplexed signal;
- defining a situational awareness window in the time division multiplexed signal;
- defining a voice relay window in the time division multiplexed signal;
- defining a situational awareness relay window in the time division multiplexed signal;
- receiving a voice data packet during the primary voice window;
- receiving a situational awareness data packet during the situational awareness window;
- retransmitting the voice data packet to other network nodes in a plurality of network nodes during the voice relay window;
- and
- retransmitting the situational awareness data packet to other network nodes in the plurality of network nodes during the situational awareness relay window.
