Data Links act as the transmission center that allow the drone to communicate with the ground operator while in flight.

Typically utilizing radio frequency technology to communicate, the data link provides the operator with crucial data like remaining flight time, distance from the operator, distance from target, airspeed altitude and more.

UAV control at $2.4 \mathrm{GHz}$ for control and $5 \mathrm{GHz}$ for video will provide the operator with approximately four miles of usability, while frequencies of $900 \mathrm{MHz}$ for flight control and $1.3 \mathrm{GHz}$ for video control can provide more than 20 miles of usability - adding to the list of reasons why pilots must use the right UAS for the task they mean to achieve.
