Unmanned aerial vehicles are controlled remotely and wirelessly via radio waves. It is an invisible electromagnetic spectrum (frequency in MHz). There should be a transmitter to send the message and a receiver to get the message that the radio waves work. A lot is that the transmitter and receiver must operate at the same frequency.

Wireless Remote Control Portable Drone Blocker GPS Frequency
WiFi is often used for remote control drone work, such as Aum AR drone 2.0, and the quality of interoperability between drones and mobile applications is very good (computers, tablets, iPads, etc. if there are any). Higher frequencies also have a wider range than lower frequencies, and also bring better sharpness for intensive use, such as 900MHz for drone transmissions. GPS (Global Positioning System) frequencies L1 (1575.42MHz) L2 (1227.60MHz) L5 (1176.45MHz) are used to send location data to the drone control. GNSS (Overall Navigation Satellite System) mainly includes GPS (USD), Gaileo (Europe), Glonass (Russia), BDS (China), QZSS (Japan) and IRNSS (India). The normal frequency is the operation of common drones 433MHz, 900MHz, 1.2G, 2.4G, 5.2G, 5.8G, etc. (430-440MHz, 2.4G-2.4835GHz, 5.15-5.35GHz, 5.725-5.850GHz).

As drones become more common around the world, black flies are actually often seen. topsignaljammer provides an absolutely effective solution for drone blackfly - drone jammer.
