Rep1 COFDM-Relaismodul

 — COFDM-Demodulation und Remodulation
    — Stabile Signalübertragung in NLOS und Hochgeschwindigkeitsbewegungen
    — Einstellbare Arbeitsfrequenz, Bandbreite, transmission power, etc

Rep1 relay module accepts COFDM signals from two antennas(can just use one too) and demodulates it, then re-modulates and transmits. The relay module can find and lock automatically to the incoming transmission quickly according to the pre-set frequency and bandwidth.
