    > the maximum achievable throughput is 26 bps at 1.5 m and goes down to 22 bps at 4.5 m.

    And when there are more than one transmitters in real world conditions instead of anechoic chamber?

    It's cool and all and if this work is for it's own sake, for the sake of research, no issues. But otherwise, I struggle to think of practical use cases. I grant that my imagination may be deficient.

      Figure 9C in the paper shows testing in a wooded area. Figure 9F shows transmitted data collected in a residential building, so not a test chamber.
