Patent ID: 8670493

Claim:
A system that is configured to communicate information, the system comprising: a first communications mode comprising a wireless communications link that is based upon radio frequency emissions; and a second communications mode comprising a wireless communications link that is based upon radio frequency emissions and an increased level of privacy compared to the first communications mode; wherein the system is configured to preferentially use the second communications mode to communicate the information and refrain from using the first communications mode to communicate the information responsive to a privacy level of the information being above a threshold; wherein the system is further configured to preferentially use the first communications mode to communicate the information and refrain from using the second communications mode to communicate the information responsive to the privacy level of the information being below the threshold; wherein the system further comprises a signaling alphabet comprising a plurality of waveforms that are orthogonal therebetween; and wherein the second communications mode is based upon the signaling alphabet that comprises the plurality of waveforms that are orthogonal therebetween.
