— COFDM demodulation and re-modulation
— Stable signal transfer in NLOS and high speed moving
— تردد العمل قابل للتعديل, band width, قوة الإرسال, إلخ
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.
