Quadrature phase shift keying transmits two information bits, combined as one symbol, for a stable transmission signal.
Control distance: 2.5 miles (4km) on air. (Actual control distance depends on the flying environment)
Lower signal noise with a channel Bandwidth* of 5.0 MHz, RF power output is over 100mW for a stable response. The AT9S is an excellent choice for Professional Aerial, Agricultural and Industrial drones.
*DSSS(Direct Sequence Spread Spectrum)
*FHSS(Frequency Hopping Spread Spectrum)
*Bandwidth: The difference between the upper and lower frequencies in a band of frequencies.
The AT10II uses 2400MHz to 2483.5MHz.
