5. RF Characteristics The SoundCast RF algorithm is described below paying special attention to include information pertinent to FCC and ETSI regulations. The SoundCast software operates by selecting a palette (or group) of 15 random channels out of the total 38 to hop on. For the 15-channel palette, any channels with poor transmission rates are replaced with better channels from the remaining 23 unused channels. The hopping pattern from channel to channel is a random pattern.
