I used USRP1+BasicTX, USRP1+TVRX and ./benchmark_rx/tx.py to transmit packets but used different bitrate (35K, 125K, 216K) in FM bands (88Mhz~108Mhz)
Why the 35K can reached distance longer than 125K and 216K.
In my implementation result, the 35K was 20m, 125 was 18m and 216 was 16m.
Why have this result, the modulation was same, just different bitrate.
Thanks in advance.
