It uses 2.4 GHz for control and is powered by a 2000mAh battery, giving it a flight time of about 15 minutes. [2] [3] [4] It did not include a built-in camera, but it can be fitted with an optional mount for a GoPro HERO camera. [4] The drone uses a GPS-enabled NAZA-M autopilot system allowing it to hover with automatic wind resistance. [2] [5]
900 MHz, 1.2 GHz (amateur radio licensees only), 2.4 GHz, and 5.8 GHz. [4] Specialized long-range UHF control systems operate at 433 MHz (for amateur radio licensees only — especially with Switzerland having exclusive allocations for them, and secondary usage in much of North America) [6] [7] or 869 MHz [4] and are commonly used to achieve ...
In the early 21st century, 2.4 gigahertz spread spectrum RC control systems have become increasingly utilized in control of model vehicles and aircraft. Now, these 2.4 GHz systems are being made by most radio manufacturers. These radio systems range in price from a couple thousand dollars, all the way down to under US$30 for some. Some ...
Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. To reduce interference with other protocols that use the 2.45 GHz band, the Bluetooth protocol divides the band into 80 channels (numbered from 0 to 79, each 1 MHz wide) and changes channels up to 1600 times per second.
