RF TRANSMISSION Radio frequency (RF) transmission uses radio waves like radio or television signals to transmit audio via a carrier from transmitter to receiver. The transmitter has an antenna usually attached to the transmitter unit, which needs to be positioned adequately cover the listening area. Transmitter and receiver communicate between them through Manchester coding for RF transmission. Manchester coding works on transitions from high to low (for bit 0) and low to high (for bit 1). The actual width of the pulses doesn’t matter particularly (within reason).Packet system transmission in terms of reliability. The packet consists of a no. of different sections.
