A transceiver dongle enables signal penetration into a building. The transceiver dongle includes an interface for connecting the transceiver dongle with a processing circuit that provides a received RF signal. A signal processing chipset converts the received RF signals to a format that overcomes losses occurring when the RF signals penetrate a structure of the building over a wireless communications link. Transceiver circuitry converts between the RF signals and signals in the format that overcomes losses occurring when the RF signals penetrate the structure of the building as controlled by the signal processing chipset. An antenna transmits and receives the signals in the format that overcomes losses from the transceiver circuitry between the transceiver dongle and a second transceiver dongle.

A system, method, and device for RF upconversion. The system can include a laser, two EAMs, a photonic filter, a photonic service filter, two photodiodes, and a mixer. The first EAM can convert a received RF signal into the photonic domain by modulating an optical signal (received from the laser) based on the received RF signal to output a modulated optical signal. The photonic filter can output a filtered optical signal based on the modulated optical signal to the first photodiode which can output a filtered RF signal in the RF domain. The second EAM can output an LO modulated optical signal based on a received LO to the service filter which can output a filtered LO optical signal to the second photodiode which can output a filtered LO signal in the RF domain. The mixer can mix the filtered RF and LO signals to generate an IF signal.

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 0.2V/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.
