Enclosed space communication systems and related methods

摘要

Systems and methods for communication in enclosed areas. Implementations may include a high-frequency (HF) conversion side including an HF modulator and HF demodulator which is coupled with an HF antenna. A medium-frequency (MF) conversion side including an MF modulator and an MF demodulator which is coupled with an MF antenna may also be included. The HF conversion side may be coupled to the MF conversion side at the HF demodulator and the HF modulator. The HF conversion side may be physically separate from the MF conversion side.
