Abstract
A communication system and method is described, including two or more transceivers at different locations, in which a region of the atmosphere at an altitude ranging from 150-350 KM is modified by applying an E-Field strength of 0.2 V/m to create a High-Frequency Ionized Lines/High-Frequency Plasma Lines (HFIL/HFPL) region. The HFIL/HFPL region provides a means for incoming RF transmission signals to be isotropically repeated and received by transceivers at other distant locations within line-of-sight of the HFIL/HFPL region. Incoming RF transmissions into the HFIL/HFPL region may use radio frequencies ranging from 100 MHz-20 GHz. The system described offers a means for users to transmit data from one over-the-horizon location to another at distances up to 4800 km without wires or physical satellites.
