1. A long distance wireless communications device for use with a handheld wireless communications device of the type designed for wirelessly communicating short messaging using short-wavelength wireless infrastructure using the handheld wireless communications device short messaging capability, the long distance wireless communications device comprising:

  • a housing that at least partially encases the handheld wireless communications device;

    a data interface disposed in the housing, the data interface configured to interface with the handheld wireless communications device short messaging capability, the data interface being operatively coupled to a high frequency (HF) radio communications transceiver, the data interface being configured to enable the handheld wireless communications device to communicate a short message via the high frequency radio communications transceiver as another way to exchange the short message the handheld wireless communications device is capable of communicating using the short-wavelength wireless infrastructure;

    the high frequency (HF) radio communications transceiver disposed in the housing and capable of operating in the high frequency (HF) range of 3 to 30 MHz, the high frequency (HF) radio communications transceiver providing short messaging wireless data communications on 3 to 30 MHz for long distance communication, thereby providing alternative, long distance wireless communications of short messaging to/from said handheld wireless communications device.
