Rep1 COFDM Relay Module

 — COFDM demodulation and re-modulation
    — Stable signal transfer in NLOS and high speed moving
    — Adjustable working frequency, band width, transmission power, vb

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.
