1. A system for communicating voice or data information in an enclosed space, the system comprising:
- a high-frequency (HF) conversion side comprising an HF modulator and an HF demodulator and coupled with an HF antenna; and
a medium-frequency (MF) conversion side comprising an MF modulator and an MF demodulator and coupled with an MF antenna;
wherein the HF conversion side is coupled to the MF conversion side at the HF demodulator and the HF modulator;
wherein the HF conversion side is adapted to receive a first HF signal from the HF antenna and produce a first baseband signal and to receive a second baseband signal from the MF conversion side and produce a second HF signal;
wherein the MF conversion side is adapted to receive the first baseband signal and produce a first MF signal and to receive a second MF signal from the MF antenna and produce the second baseband signal; and
wherein the HF conversion side is physically separate from the MF conversion side.

Abstract
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.
