What is drone transmission link?
Drones use various transmission technologies for communication between the drone and the remote controller, as well as for transmitting data such as live video feeds and telemetry information. Here are some common drone transmission types:
Radio Frequency (RF) Transmission:
2.4 GHz: This is a common frequency band for consumer drones. It provides a good balance between range and signal penetration.
5.8 GHz: Another frequency band used for drone communication. It offers higher data transfer rates but may have slightly shorter range compared to 2.4 GHz.
DJI Lightbridge and OcuSync: DJI, a popular drone manufacturer, uses proprietary digital transmission technologies like Lightbridge and OcuSync for high-quality video streaming and control signals. These systems often operate on 2.4 GHz or 5.8 GHz frequencies.
Some drones use Wi-Fi for communication between the drone and the remote controller. Wi-Fi is often employed for short-range communication and is commonly found in entry-level or toy drones.
Bluetooth is used for short-range communication, typically for tasks such as connecting a smartphone or tablet to the drone's remote controller.
Some advanced drones can leverage cellular networks for communication. This allows for extended ranges and the ability to control the drone from remote locations, although this is less common in consumer drones.
Infrared technology is used for close-range communication, often for tasks like obstacle avoidance. It is not the primary means of communication for most drones but is an additional feature in some models.
In certain situations, drones designed for long-range operations, such as in industrial or agricultural settings, may use satellite communication for control and data transmission.
Some drones use hybrid systems that combine multiple transmission technologies. For example, they may use RF for control signals and a separate video transmission system for live video feeds.
The specific transmission type depends on the drone's purpose, range requirements, and the manufacturer's design choices. Advances in technology continually bring new and improved transmission methods to the drone market.
