2.4-GHz radio system makes flying RC planes and helicopters even more fun!
Until recently, the frequency of security is a concern for every flight, RC airplanes or helicopters, but with the 2.4 GHz radio, which is no longer a problem. Since the additional advantages of faster response and time of flight and the longest battery life, if someone new to fly RC planes definitely take into account a 2.4 Ghz.
In traditional narrow-band set, a separate frequency is needed to send data from the transmitter (TX) to receiver (RX) and then to the servant. When pilots and BC fly RC aircraft with the same frequency as the pilot, who will perform with the A signal interference and able to take it to crash. Spread-spectrum technology works in a different way, remove with a wider frequency band and "spreading" the signal over the whole area broader than narrow-band interference from other 2.4 GHz radios or groups.
There are two main types of spread spectrum systems, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS). DSSS radios to send data viaa wide range of frequencies, but to remain in a fixed part of the 2.4 GHz band, while FHSS systems operate on a narrow range of 2.4, jumping hundreds of times per second at different frequencies. JR and Spektrum radio systems use DSSS technology, Futaba and Airtronics 2.4 GHz FHSS uses deal.
Both methods of transmission of the signal and reject noise. Both have less power than set to narrow band, ie, longer flight times and a longer life for yourBatteries. Many RC pilots even as their narrow-band radio, but it's been flying RC planes 2.4 possible without fear of interference. If only come to the hobby, or thinking about updating your old radio sysytem, a frequency of 2.4 GHz is steadily growing!
