1. A mobile device comprising:

  • a processor that is configured to; and

    a computer-readable memory having computer program instructions stored in the memory, that when executed by the processor control the mobile device to perform operations comprising;

    communicating using a first communications mode comprising, wherein the first communications mode comprises a first level of security/privacy and a first wireless communications link that is based upon radio frequency emissions communications comprising a first air interface, a first power symbol energy to noise level, a first cyclostationary signature and a first detectability measure that is based upon the first power symbol energy to noise level and the first cyclostationary signature;

    communicating using a second communications mode comprising, wherein the second communications mode comprises a second level of security/privacy that is greater than the first level of security/privacy and a second wireless communications link that is based upon radio frequency emissions communications comprising a second power symbol energy to noise level that is less than the first power symbol energy to noise level for the same bit error rate, a second air interface that differs from the first air interface, a second cyclostationary signature that differs from the first cyclostationary signature and comprises a reduction relative to the first cyclostationary signature and a second detectability measure that is less than the first detectability measure based upon the second power symbol energy to noise level being less than the first power symbol energy to noise level for the same bit error rate and based upon the second cyclostationary signature comprising said reduction relative to the first cyclostationary signature;

    determining a privacy level of information that is to be transmitted;

    responsive to the privacy level of the information that is to be transmitted comprising the first level of security/privacy, using the first communications mode to communicate the information that is associated with the first level of security/privacy while refraining from using the second communications mode to communicate the information that is associated with the first level of security/privacy;

    andresponsive to the privacy level of the information that is to be transmitted comprising the second level of security/privacy, using the second communications mode to communicate the information that is associated with the second level of security/privacy while refraining from using the first communications mode to communicate the information that is associated with the second level of security/privacy;

    wirelessly communicating with a base station, at a first distance from the base station, using the first communications mode comprising the first level of security/privacy; and

    wirelessly communicating with an access point, at a second distance from the access point that is less than the first distance, using the second communications mode comprising the second level of security/privacy that is greater than the first level of security/privacy, responsive to a proximity condition having been satisfied by the mobile device relative to the access point.
