How do drones communicate over long distance?

The most common method of drone communications uses radio frequency (RF) signals in bands such as HF (high frequency) and UHF (ultra high frequency). RF data links can be analog or digital and offer a longer range than Wi-Fi, but they are still limited to line of sight (LOS). Autonomous drones require a radio or Wi-Fi to communicate with a connected network. Radio-controlled drones operate between 2.4 GHz and 5.8 GHz.

The quadcopter uses radio frequency to connect to a terrestrial transmitter. Drones can also be controlled with a cellular network that is constantly available throughout the city and the LTE base station makes them a more accurate and effective solution for controlling drones in a long-range communication system. Communication between the drone and the controller is usually via radio, Wi-Fi or GPS signals. The type and intensity of the type of communication affect the distance the drone can fly from the controller.

Today, drones perform many tasks and, as with all other devices that rely on electronic communications, drones send and receive transmissions over a particular frequency. To perform their tasks effectively, drones rely on long-range communication. That's why drones require a radio signal or WiFi to communicate with a connected network. We offer a comprehensive drone delivery solution that is easy, fast and accurate for any business use and for working with long-range communication drones.

The drone and the remote control are connected by an invisible strap that prevents the drone from flying away. The effectiveness of any drone in the sky depends on the communication between the drone and the controller. Another name for a drone controller is a drone radio controller, and it is solely responsible for all of the drone's activities. This can be useful for drones that need to travel a long distance or for drones that are used in search and rescue operations.

This is the most common way to control drones and involves a person flying the drone from a distance. Each drone's IP address changes each time it crosses a new cellular network, making it even more difficult to track each drone's IPs. The radio signal that is sent to the drone comes from this transmitter and is received by the drone's receiver. Some drones can also be controlled via Wi-Fi or Bluetooth, allowing for a more direct connection between the controller and the drone.

As for the use of a drone for search and rescue missions, the 4G network allows a drone to fly several miles from the controller or pilot. However, we should mention that, as drone technology and battery life improve, it's not uncommon for some drones to reach a range of up to 6 miles or more.
